| 14:13 | Un-microcoded the RAL HLT instruction in examples/bit-rotate.pal: it tickles a palbart bug, because these are group 1 and group 2 OPR instructions, respectively! Consequently, the SIMH PDP-8 assembler sees only the HLT and doesn't do the RAL. check-in: 193d34204c user: tangent tags: trunk | |
| 06:58 | Clarity pass on the top-level README.md file. check-in: e2fd19eea1 user: tangent tags: trunk | |
| 06:18 | The mkrel process now does a "fossil diff -w | less" just before the "fossil ci" command, giving the user a chance to see the diffs in what they just built, to be sure nothing surprising got merged. check-in: c2eaa6ca27 user: tangent tags: trunk | |
| 06:14 | Removed src/gpio-nls.h: the differences between the two versions of the GPIO module are all in the *.c files. No point shipping two identical *.h files, especially given that no other *.c file has ever #included gpio-nls.h. check-in: a22a47a8fa user: tangent tags: trunk | |
| 06:03 | Similar comment fix for src/gpio-nls.c as was just done on the no-lamp-simulator branch. check-in: 63858bf03c user: tangent tags: trunk | |
| 05:56 | The check for brtval in src/PDP8/pdp8_cpu.c.in became obsolete when we extracted the bulk of the front panel interaction code to the new pidp8i.c.in module. Rather than change the test to look in that new file, changed it to look in src/gpio.c, which is shorter and accomplishes the same goal. check-in: d2dd4232ce user: tangent tags: trunk | |

| 19:17 | Clarified code style rules check-in: a0cbc61e11 user: tangent tags: trunk | |
| 15:45 | Assorted improvements to HACKERS.md check-in: b20d93bc02 user: tangent tags: trunk | |
| 15:19 | Reindented src/PDP8/pidp8i.c.in to match new style guide in HACKERS.md. Bascially, function bodies were indented one level, except for closing braces which came back out one level. check-in: f52f8dda3c user: tangent tags: trunk | |
| 15:09 | Added "Getting Developer Access" section to HACKERS.md check-in: f2e7f25699 user: tangent tags: trunk | |
| 15:07 | Added Fossil installation info and tweaked the one-sentence Fossil description. check-in: b2f9adf4ce user: tangent tags: trunk | |
| 14:56 | First version of HACKERS.md, a more thorough guide to contributing to the PiDP-8/I software project than the brief hints given on the front page of the site. (wiki/Home). check-in: 34cac8687c user: tangent tags: trunk | |

| 22:45 | The CPU cleanup branch seems to be 100% functional again. Merged it into trunk. check-in: 768cc6393f user: tangent tags: trunk | |
| 05:14 | Reworked some of the bosi steps after the recent change to where the usermod step happens. These changes should have been part of that. check-in: 2a4574d15f user: tangent tags: trunk | |
|
2017-01-17
| ||
| 05:00 | Small fix to previous check-in: 6888919960 user: tangent tags: trunk | |
| 04:58 | The usermod command in bosi's reset routine only worked correctly on the first pass, since the user was still called "pi". If run again on a later pass where that user is now called pipd8i, it now only does the password change. check-in: 34d25dce5b user: tangent tags: trunk | |
| 04:50 | The bosi script now calls tools/mmake instead of hard-coding a "make -jN" command. check-in: fd8a2cb4ab user: tangent tags: trunk | |
| 04:48 | Ported difference minimization between src/gpio* modules from the no-lamp-simulator branch where the only difference between these files is a comment to the trunk branch where the differences are more substantial, but where the needless diffs should still be removed. check-in: ec5fd1c92c user: tangent tags: trunk | |
| 03:42 | Auto-detecting the OS SD card dev name in the bosi script instead of hardcoding it to /dev/rdisk10. check-in: 74e29589ed user: tangent tags: trunk | |
| 02:59 | Put off the usermod command in the bosi script from the "init" step to the "reset" step so the user doesn't have to enter the long "edson" password during image builds. check-in: 8c87a6d3b4 user: tangent tags: trunk | |
| 02:19 | Grammar fix check-in: f0f422eae7 user: tangent tags: trunk | |
| 01:55 | Fixed "bash -e" -> "set -e" in mkrel script; not equivalent! check-in: bbdb2e69ef user: tangent tags: trunk | |
| 01:51 | Release v20170116 again: fix to the single-core + lamp simulator test in `auto.def` that only broke on the `no-lamp-simulator` branch, so had to fix it on trunk and string the changes back through the release process. check-in: a8e26c97f5 user: tangent tags: trunk | |
| 01:38 | The mkrel script now runs "fossil update" prior to any merge steps in case the local ../release and ../no-lamp-simulator checkout trees aren't at the tips of their branches at mkrel time. check-in: 1ff16590d5 user: tangent tags: trunk | |
| 01:36 | Tagged release v20170116 check-in: 01c815b3d6 user: tangent tags: trunk | |
| 01:10 | Lowered the single-core throttle value from 1600k to 1332k per feedback from the mailing list, and outright refusing to build the trunk branch on a single-core Pi. Explained all this in the relevant README*.md files. check-in: b9c60a41ad user: tangent tags: trunk | |
| 00:45 | The mkrel process now breaks out immediately after a merge that creates a conflict instead of waiting to fail in the build process due to hitting the <<<<<< characters, which give confusing error messages. check-in: 32be7a1d8a user: tangent tags: trunk | |
| 00:07 | Updated the COPYING.md file with the results from the SIMH mailing list thread (http://mailman.trailing-edge.com/pipermail/simh/2017-January/016159.html) about TSS/8 and ETOS. check-in: 0dfac12323 user: tangent tags: trunk | |
|
2017-01-14
| ||
| 07:49 | Moved the installation of the boot scripts from "make install" to "make mediainstall". We shouldn't overwrite the boot scripts for the same reason we shouldn't overwrite the binary media images. check-in: 54324622fc user: tangent tags: trunk | |
| 07:39 | Added a sched_yield() call to the end of the main GPIO loop to clue the scheduler that we're done for that iteration. The fflush() call we have there already may suffice, but at the very least, this is explicit. check-in: dc48d6cd85 user: tangent tags: trunk | |
| 07:37 | Lowered the scheduling priority of the GPIO thread from 98 (near the max of 99) to 4 (still well above the minimum of 1) since this seems to work just as well. This may simply be because no other processes on the Pi are using SCHED_FIFO. check-in: 3fd8bee1ba user: tangent tags: trunk | |

2017-01-13

| 08:38 | Modified copyright year on the AC/MQ blinker program license per email from Robert Krten. check-in: 063e8b86ca user: tangent tags: trunk | |
|
2017-01-12
| ||
| 19:47 | Obtained permission to distribute the AC/MQ blinker program under the SIMH license, so added that license to the top of examples/ac-mq-blinker.pal. Quoting the reply to my email asking for permission: "I, Robert Krten, the sole author of the program identified as the "AC/MQ blinker program" for the PDP-8/I, hereby agree to distribute the program under the SIMH license as found at https://tangentsoft.com/pidp8i/doc/trunk/SIMH-LICENSE.md" check-in: 58094e0cf4 user: tangent tags: trunk | |
| 06:43 | Another URL fix in the new licensing material check-in: e0241770dd user: tangent tags: trunk | |
| 06:40 | Added copyright messages to the Markdown files that reference SIMH-LICENSE.md so that it is clear who is granting the license. check-in: 160483044a user: tangent tags: trunk | |
| 06:37 | Added license section to end of examples/README.md check-in: 7024cc51a2 user: tangent tags: trunk | |
| 06:35 | Clarifications to the DEC hobbyist license claim in COPYING.md. check-in: 08b984e585 user: tangent tags: trunk | |
| 06:25 | Small link fix for previous checkin check-in: f360190dd4 user: tangent tags: trunk | |
| 06:24 | Many more software licenses chased down and added to the appropriate files. Where direct editing was not possible, created license files nearby, and pointed to them from a new COPYING.md file. check-in: fc7e5f2a91 user: tangent tags: trunk | |
|
2017-01-09
| ||
| 22:27 | Added the new SIMH-style license grant to the header comment of the gpio*.c modules, and added Ian Schofield to the gpio.c module (only!) and to the pdp8_cpu.c.in module, per this private email reply to my licensing proposal: "This looks absolutely fine to me. Do add this license to the tarball if we all agree." check-in: 06829f12b1 user: tangent tags: trunk | |
| 22:09 | SIMH doesn't support THROTTLE values below 1k (or maybe 10k) so changed the --throttle=human and =trace configure script options to use a different syntax which allows specifying speed in terms of instructions/ms. check-in: 26a6b02367 user: tangent tags: trunk | |
| 04:03 | Lowercased the "SET [NO]THROTTLE" commands to match the style of the existing boot/*.script commands. SIMH doesn't care, but it's inconsistent. check-in: 0e15f11ea2 user: tangent tags: trunk | |
| 02:56 | Added the license notice to src/scanswitch.c as well check-in: ffa1390cb8 user: tangent tags: trunk | |
|
2017-01-08
| ||
| 15:53 | The *BSDs all understand sysctl hw.ncpu, so added tests for those to tools/corecount, so it'll return the correct value on them, too. check-in: 4be8a6510e user: tangent tags: trunk | |
| 15:36 | We weren't cleaning up after a few of the recently-added *.in files in "make clean". Fixed. check-in: 8cd4016117 user: tangent tags: trunk | |
| 15:03 | A prior checkin accidentally changed the way HLT instructions are handled. It was an attempt to fix bug [f961906a5c] which wasn't intended to be checked in; the fix doesn't work, so it's now back to the way the code worked yesterday, which is still broken. check-in: 6155a4b535 user: tangent tags: trunk | |
| 14:39 | Adjusted the single-core SIMH throttle value down from 3.3 MIPS to 1.6 MIPS. The prior value gave about 50% CPU usage for all threads in pidp8i-sim on a Pi 3, so cut it in half for a Pi 1. Also had to change the notation from "3.3M" to "1600k" because SIMH refuses to handle fractional values; LAME. check-in: 0770a4a2ec user: tangent tags: trunk | |
| 14:26 | All of the boot scripts except for those generated from assembly code now have a SIMH throttle value set based on either detected CPU cores at configuration time or the value of the new --throttle configure script value. Added README-throttle.md to describe the values allowed for this option, as they're pretty extensive. On a multi-core machine, the default is to have the prior behavior, which is no throttling: run flat-out, taking up a whole CPU core for pidp8i-sim's main thread, leaving the rest for the GPIO thread and whatever else the Pi does. On a single-core machine, the default is to set a value that should give something like 50% CPU usage to pidp8i-sim on the slowest Raspberry Pis we support, allowing enough CPU power left over for the incandescent lamp simulator thread. Consequently, removed README-single-core.md and the references to it. Closes [dfd864da90]. check-in: 48b84d4bd9 user: tangent tags: trunk | |
| 11:11 | The mkrel process now attempts to do all the work automatically, with no user input. The prior release showed that the gap between releases is long enough that I can't remember what to write as release comments, and because the comment editor takes over the screen, I can't figure it out from the context of previously-executed commands, since the editor hides that. check-in: 58e0f138a0 user: tangent tags: trunk | |
| 11:05 | Replaced the "make -j11" hard-coded values with a call to a new helper script, tools/mmake which calls another newly-added script (tools/corecount) to get the core count on this system and multiply it by 1.5 and pass it to make -j. It currently knows how to do this on Linux and Mac OS X. For all other systems, it returns 1, so it gives you make -j1, since the math truncates, rather than rounds. This is not just a nicety: "make -j11" can lock up a Pi in some cases. It appears to be worst when most of the files in the system have to be rebuilt. It's probably running the system out of RAM, and it isn't handling it gracefully. check-in: cffeb65eb8 user: tangent tags: trunk | |
| 10:53 | Style improvments to the coverage of ./configure script options in README.md. check-in: e30b30d2ef user: tangent tags: trunk | |
| 10:31 | Backed out part of [842fb3ef61] since now all of boot/*.script are generated in one way or another. Therefore, we no longer need to install @srcdir@/boot/*.script. (This doesn't revert the change, it effectively *inverts* the way this install step worked prior to that checkin: we used to install only from the srcdir, but now we install only from the builddir.) check-in: 71586b261d user: tangent tags: trunk | |
| 10:27 | Added tools/mkbootscript, a Perl script that parses palbart listing files generated during the normal build process and turns them into SIMH boot scripts. This in turn means we can remove boot/1.script and boot/5.script, since they can now be generated from corresponding programs in examples/*.pal. Closes [87cb9ca2f0] check-in: d77e169826 user: tangent tags: trunk | |
| 10:21 | Added examples/bit-rotate.pal, a very simple demo, which we'll be using as a test case shortly. check-in: 06b08e0c58 user: tangent tags: trunk | |
| 10:21 | Added examples/asr33-rim-loader.pal, the Teletype Model 33 ASR version of examples/hs-rim-loader.pal, corresponding to what is currently checked in as boot/asr33-rim-loader.script. check-in: cd98f98dd1 user: tangent tags: trunk | |
| 09:53 | Added examples/hs-rim-loader.pal, PAL assembly code for the high-speed RIM paper tape loader currently given in boot/1.script. It produces the same code, except that it starts 1 location earlier in core with a HLT instruction, which will become important later. check-in: 5b4b65874f user: tangent tags: trunk | |
| 08:42 | More style improvements to examples/ac-mq-blinker.pal, plus some rework to the memory locations it uses to match boot/5.script. check-in: f7c67eb7f8 user: tangent tags: trunk | |
| 08:17 | Comment improvement check-in: 8dd4e8e1d1 user: tangent tags: trunk | |
| 07:37 | Small fix to prior comment change check-in: 595d5cc4f8 user: tangent tags: trunk | |
| 06:39 | Minor code cleanups in examples/add.pal check-in: 6b8786042e user: tangent tags: trunk | |
| 06:30 | When cloning the SIMH license agreement for the new authors, accidentally included "ROBERT M SUPNIK" in the no-warranty clause. Substituted generic "the authors" language. Also regularized the whitespace of the clause after that to match the rest. check-in: 81915a1c50 user: tangent tags: trunk | |
| 06:19 | When building out-of-tree, only the boot/*.script files in the src tree would be installed. Now installing both those and the ones in the build tree generated from boot/*.script.in. This means that building in-tree causes the same files to be copied twice for each such generated script, but that's harmless. check-in: 842fb3ef61 user: tangent tags: trunk | |
| 05:53 | Replaced several gotos with "continue" statements: the goto label was at the end of a while() loop, and all of the "goto skip" statements were up at that while loop's level, so there was no need to use goto here. check-in: 270d24975c user: tangent tags: trunk | |
| 05:31 | Fixed a needless whitespace difference with respect to upstream SIMH code. check-in: 7085e873a6 user: tangent tags: trunk | |
| 05:19 | Applied a patch from the mailing list: https://groups.google.com/d/msg/pidp-8/DzpKgmC7bck/4_3hr53yCwAJ This patch allows the simulator's internal EAE's step counter value to be displayed on the PiDP-8/I front panel. Without this patch, those LEDs remain dark, even when the simulator is doing work that should make them blink. This patch got lost for so long because it was supposed to go into the "next version" of Oscar Vermeulen's source base, but there was no such version. Since this happened well before my maintainership, it was lost until Paul R. Bernard pointed it out to me. check-in: ab402f9eaf user: tangent tags: trunk | |
| 03:31 | Added a copy of the SIMH license agreement to the top of src/test.c, modified to refer to its author, Paul R. Bernard. The license grant was obtained via private email; in reply to the same message referenced in the prior checkin, PRB said, "I agree with your license changes." check-in: 17b7de432b user: tangent tags: trunk | |
| 03:27 | Added a similar license to the existing SIMH one to the top of pdp8_cpu.c.in and scp.c.in, allowing the changes made by Oscar Vermeulen and Warren Young to be used on the same terms as SIMH itself. The license grant from Oscar Vermeulen was obtained via private email: WY: "To make things truly simple, I propose using the same license SIMH itself uses. I hereby agree to license my changes to the current software under the following license: [same text as committed here snipped]" And in reply: OV: "I agree - happy to keep my part under the original simh license." check-in: b536178bf2 user: tangent tags: trunk | |

2017-01-06
| ||
| 02:13 | Merged auto.def fix down from release branch into trunk. (Should have been committed on trunk in the first place. It wasn't due to doing it on a system that still used the old "release" tag, as opposed to the "release" branch.) check-in: 99b6a17f83 user: tangent tags: trunk | |
| 00:26 | "Trouble with grammar have I, yes!" -- Yoda check-in: f81e019087 user: tangent tags: trunk | |
| 00:22 | Minor tweaks to the new ChangeLog.md entries check-in: 9d5cc2b126 user: tangent tags: trunk | |
| 00:15 | Release version v20170105 check-in: c44994abee user: tangent tags: trunk | |
| 00:14 | Updated SIMH to upstream Git commit ID 0db0236bed using the new simh-update mechanism. (No manual adjustment was required, other than the whitespace fix committed a few hours ago.) check-in: cd1db2713d user: tangent tags: trunk | |
|
2017-01-05
| ||
| 23:55 | Added "make simh-update" and "make simh-update-f" targets which run a new script, tools/simh-update [-f]. That script attempts to merge the latest upstream SIMH changes into our source tree by checking out both the last version we successfully merged and the current master tip and applying the diffs between our software and the old checkout version to the new software. Closes [c20a953737] check-in: 8f452f4205 user: tangent tags: trunk | |
| 22:43 | src/scp.c.in is also allowed to have CRLF line endings check-in: 383f3f6bd1 user: tangent tags: trunk | |
| 22:42 | The recent SIMH update missed a trailing space in one of the files, causing a needless diff, and preventing automatic merging. check-in: d84c630e8f user: tangent tags: trunk | |
| 19:23 | The generated Makefile now passes the upstream SIMH git commit ID of the software we most recently merged into our distribution to the compiler so that it's built into the resulting pidp8i-sim program, so that it's displayed as part of the version string. This allows users of our software to report bugs upstream while referencing a version that is meaningful to the upstream project. check-in: 69b66e7294 user: tangent tags: trunk | |

| 22:30 | Added Tony Hill to the AUTHORS.md file, and credited him for the SIMH update. check-in: 8f2ec6aeec user: tangent tags: trunk | |
| 22:25 | Added bit about `no-lamp-simulator` branch merge to the release process doc check-in: 6aa9caad1f user: tangent tags: trunk | |
| 22:24 | Updated the release process document to reflect the latest changes to the way we handle the `release` branch, as opposed to the old `release` tag. check-in: b8588b9af5 user: tangent tags: trunk | |
| 22:04 | Release v20161226 check-in: 242018031d user: tangent tags: trunk | |
| 21:44 | whitespace cleanup of oscar's mods to the simh code - just because check-in: 6a57d2c5cc user: tony tags: trunk | |
| 20:34 | Linked the README.md file to the new "Major Differences" wiki article. check-in: 3058858d68 user: tangent tags: trunk | |
| 20:23 | Merged simh-update branch into trunk check-in: 9025c14510 user: tangent tags: trunk | |
| 20:07 | Merged the tip of the release branch into trunk again. Not sure why the previous merge didn't get absolutely everything, but it did manage to miss the last few release branch changes somehow. check-in: 0e9d5e4a4e user: tangent tags: trunk | |
|
2016-12-25
| ||
| 15:32 | Moved all trunk checkins from the v20161203 release point to a new long-lived "release" branch, then merged the tip of that branch (the previous trunk tip) into the actual trunk. The end result is that we have a few weeks of checkins that all appear to be release versions, but that will disappear into history soon. check-in: c39069fdfb user: tangent tags: trunk | |

| 08:06 | Using those new GPIO module API array constants in scanswitch and pidp8i-test now, too. check-in: 4cff15b2c9 user: tangent tags: trunk | |
| 08:00 | Added a time-based state machine to the GPIO module's switch state change handler that doesn't report the new state of a switch after observing a change until it has remained stable in a state different from the last one reported to other modules for at least 50 ms to give the switch contacts time to stop bouncing. Closes [fcbd41dd0d] This checkin also replaces a bunch of naked constants in that same module with named constants that are calculated by the compiler, so they're always correct. check-in: 07882c14fe user: tangent tags: trunk | |
| 04:10 | Fixed a typedef, broken in one of the recent checkins. check-in: b6d5aeffdd user: tangent tags: trunk | |
| 03:58 | Comment fix check-in: 07a2501c15 user: tangent tags: trunk | |
| 03:27 | Much of scanswitch.c and gpio.c were duplicated. Exported these things as public API elements of the gpio module, and simply linked scanswitch to gpio.o. Also unified the delay mechanisms. check-in: d6d34de7ec user: tangent tags: trunk | |
| 01:53 | Moved the "extern foo" stuff scattered around the various programs into gpio.h, and #including that from them. Also replaced some of the custom typedefs for sized int types to stdint.h types. (e.g. uint32 -> uint32_t.) These are in the same checkin because both affect the public interface to gpio.h. check-in: 0d657a6e12 user: tangent tags: trunk | |
| 01:47 | Removing tags file on 'make clean' check-in: 3aa505c477 user: tangent tags: trunk | |
| 01:37 | Made 'tags' a phony target, so make(1) won't consider it always up-to-date check-in: 39578d0dd6 user: tangent tags: trunk | |
| 01:24 | Added ctags/tags target check-in: e8d6640336 user: tangent tags: trunk | |

| 05:34 | Added a dependency on bin/palbart to the *.pt targets. Without this, a parallel make can fail because it doesn't understand that the examples can't be built until bin/palbart is present. check-in: 176a5804e6 user: tangent tags: trunk | |
| 05:26 | Removed some unnecessary instruction definitions at the top of examples/pep001.pal. (Things I defined during development but ended up not using in the final version.) check-in: d736d3fccf user: tangent tags: trunk | |
| 05:22 | Assorted fixes to new palbart target check-in: 1901c58073 user: tangent tags: trunk | |
| 05:17 | Added palbart 2.13 from https://www.pdp8online.com/ftp/software/palbart/ to the source tree and building the examples with that version instead of whatever is lying around on the system. Not only does it mean we can stop checking *.lst and *.pt into the source repo, it means we get a much newer version in many cases since the standard version you find most places is 2.4 or 2.5, which is about 6 years older, with many missing features and fixes. check-in: c77171d87c user: tangent tags: trunk | |
| 04:19 | URL fix check-in: 768019fb21 user: tangent tags: trunk | |
| 04:18 | Added README-single-core.md, and referenced it from the Prerequisites section of the top-level README.md file. check-in: 781d9c2cba user: tangent tags: trunk | |
| 04:02 | Clarity pass check-in: be2e8fa894 user: tangent tags: trunk | |
| 03:57 | Noted that "make install" does everything the old install scripts did. check-in: 3193b776f6 user: tangent tags: trunk | |
| 03:54 | Whitespace fix check-in: f8f8604fd1 user: tangent tags: trunk | |
| 03:53 | In the top-level README.md file, noted that pidp8i-test will not run if the simulator is running. check-in: 268219655c user: tangent tags: trunk | |
| 03:50 | Updated the top level README.md with the solution to a problem a user had building the software. check-in: 3030672baa user: tangent tags: trunk | |

| 15:49 | Fixed some Makefile syntax problems in the "make install" bit that removes the serial console stuff from /boot/cmdline.txt if it is present. check-in: 75f5bf32c1 user: tangent tags: trunk | |
| 15:42 | Rewrote the "make install" commands to install necessary helper programs on Debian type systems. The previous method basically skipped these steps, so those installing this on a fresh SD card wouldn't get these programs installed for them. check-in: a35d6b1ec8 user: tangent tags: trunk | |

| 15:20 | Described all the new example programs in examples/README.md check-in: 5565b86dbb user: tangent tags: trunk | |
| 13:57 | Project Euler Problem 1 is complete. I am the 617255th person to have solved this problem. Woo! check-in: e7f7715b20 user: tangent tags: trunk | |
| 12:44 | Fixed another pair of hard-coded absolute /opt/pidp8/* paths. They weren't fixed earlier because the feature involved with this code is broken ([d9592e0e7570]), so normal testing did not find the problem. check-in: b9258abd16 user: tangent tags: trunk | |
| 06:27 | Fix to the "make distclean" fix.... check-in: f85674696d user: tangent tags: trunk | |
| 06:22 | The distclean target wasn't getting rid of boot/$n.script generated from $n.script.in by autosetup under Raspbian, but did on OS X. This is probably due to the bash vs dash /bin/sh difference, as that "rm" glob pattern uses a bit more advanced shell features. check-in: 9a0b71808c user: tangent tags: trunk | |

| 20:36 | Hyperlinked README-test.md to README.md, in case you're reading the latter via Fossil UI. check-in: f17e4c520b user: tangent tags: trunk | |
| 20:00 | Added src/test.c's author to AUTHORS.md check-in: 0c06739141 user: tangent tags: trunk | |
| 19:59 | Renamed bin/pidp8i-testswitch as pidp8-test. It also tests the LEDs, and there's no reason to make the long program name even longer. check-in: b038293b7e user: tangent tags: trunk | |
| 19:21 | Merged the pidp8-test program from the mailing list as bin/pidp8i-test. It builds with the normal build process and installs as pidp8i-test in $prefix/bin. Its plain-text README is now README-test.md, formatted for display via Fossil UI, with some changes owing to its new position, but mostly unchanged. Source: https://groups.google.com/forum/#!topic/pidp-8/UmIaBv2L9Ts check-in: 05dbe80a7e user: tangent tags: trunk | |
| 08:40 | Added DEC's "Unsigned Decimal Print Subroutine" (Digital-8-22-ASCII) as examples/routines/decprt.pal check-in: 26ea2ec097 user: tangent tags: trunk | |
| 08:39 | The palbart build rule now includes -l to tell the assembler that it is allowed to generate inter-page links. check-in: 1d27f07c4a user: tangent tags: trunk | |

| 15:14 | Replaced autosetup/system.tcl with the one from upstream checkin 1899ec427 so the defaultprefix value set in auto.def shows in ./configure --help output. This replaces my local change to the previously hard-coded /usr/local string. check-in: 6c234d9cf4 user: tangent tags: trunk | |
| 14:50 | Removed the redundant copy of ETOS under the TSS/8 media directory, too. I can't see any difference between these two from an OS/8 "DIR /A =3" or "VER" command within each ETOS instance, even though md5sum assures me that there is a difference. Closes [09c24666be] check-in: cc9e5a1392 user: tangent tags: trunk | |
| 13:35 | Removed the OS/8 RK05 image under the TSS/8 directory. The only difference appears to be that the BASIC.WS file is a bit larger in the one normally used. (7 blocks rather than 5.) I'm going to assume that it's a feature we want. check-in: 81b807f0df user: tangent tags: trunk | |
| 13:29 | Removed duplicate media entries under media/tss8 for non-TSS/8 OSes. This partially addresses [09c24666be] but there are nonexact duplicates that still have to be looked into. check-in: b1f849c7b6 user: tangent tags: trunk | |

2016-11-28

| 13:24 | Assorted fixes to "make clean" target; re-tagged v20161128 check-in: bbbd662b1f user: tangent tags: trunk, v20161128 | |
| 13:16 | Squished warnings about "use parenthesis around assignment in if statement" in newer GCCs. These problems are in SimH proper, so we can't really fix them without creating needless diffs relative to SimH head, which will just complicate our eventual forward-port to SimH tip. check-in: 6cf87f044c user: tangent tags: trunk | |
| 13:14 | Fixed a bug introduced in previous in the build-in-tree case. check-in: 53715a3de2 user: tangent tags: trunk | |
| 13:11 | Assorted improvements for building the examples, particularly in the out-of-tree case. check-in: c5e65a4383 user: tangent tags: trunk | |
| 12:45 | The recent changes to make some src/*.c files autosetup templates so we can substitute $prefix/* paths into them broke out-of-tree builds. Fixed. check-in: dd83548f6a user: tangent tags: trunk | |
| 12:41 | Minor cleanups to Makefile.in. No functional change. check-in: 96c58ed962 user: tangent tags: trunk | |
| 12:31 | Improved the make clean and distclean targets. (Recent developents weren't tracked here, so they left things behind.) check-in: 0ab8580cc5 user: tangent tags: trunk | |
| 12:04 | Fixed a Tcl dialect problem in auto.def. (It works fine under the provided jimsh0, but fails under the "real" tclsh.) check-in: 4290a6b58c user: tangent tags: trunk | |
| 12:01 | Fixed a remaining vestige of the old halt-and-jump flavor of the add.pal program in examples/README.md, and made a few other clarifications. check-in: 6316f5ecde user: tangent tags: trunk | |
| 11:41 | Clarified the examples/README.md text explaining the problem with trying to run examples/add.pal under OS/8. check-in: 50d75d52d9 user: tangent tags: trunk | |
| 11:15 | Released v2016.11.28, since these recent boot script finding fixes are too important to hold for the next. check-in: 3306636201 user: tangent tags: trunk | |
| 11:13 | Replaced the two remaining uses of relative paths for finding boot scripts with absolute paths. Turns out that when running under from systemd, we can't count on the CWD to remain in $prefix/bin, so trying to restart into a different bootscript would fail. (Thus the recent change to make it not spam the console when this happens.) check-in: 308e7643d0 user: tangent tags: trunk | |
| 11:12 | Fixed a place where we were building up a boot script path too-manually. autosetup already determined the proper value for us. check-in: 926e741794 user: tangent tags: trunk | |
| 11:04 | Better error handling in the code that maps IF switches to boot script names. If the files weren't present at the expected location, it would spam the console as fast as possible. Now it just screams and dies. check-in: f08cae1d9d user: tangent tags: trunk | |
| 10:39 | Added ./configure --debug-mode flag, for setting CFLAGS+=-O0 -g. Also including -O2 when this flag is not set, for a release build. check-in: e785375d85 user: tangent tags: trunk | |
| 10:26 | Relaxed permissions on installed media and boot scripts. No point making them world-unreadable. check-in: 655ab53277 user: tangent tags: trunk | |
| 09:35 | Updated USB stick label document, created PDF version so the dot matrix fon can be embedded, and added labels/README.md, now referred to from examples/README.md. check-in: 1d19ec8a17 user: tangent tags: trunk | |
| 08:48 | Documented the method for loading the RIM-format examples/*.pt files from USB sticks, so that all three options listed at the top of the file have a full explanation below. check-in: c654e600ac user: tangent tags: trunk | |
| 08:47 | Re-assembled examples/add.pt in RIM format. check-in: d4ddafefaf user: tangent tags: trunk | |
| 08:29 | The palbart command for building the examples was generating *.pt in BIN format, but we don't want to depend on the BIN loader for such small programs. Made it emit RIM format files instead. check-in: 1da5a192e4 user: tangent tags: trunk | |
| 06:49 | Typo fix check-in: 666dfa81a9 user: tangent tags: trunk | |
| 06:47 | Fixed a couple of "PDP-8/I" references that should be "PiDP-8/I" check-in: 43ef1b33b5 user: tangent tags: trunk | |
| 06:43 | Converted some hard tabs to spaces check-in: b280b43d67 user: tangent tags: trunk | |
| 06:40 | Moved previous text a bit lower in the README.md for clarity and esthetics in the web-rendered version. check-in: 695309f535 user: tangent tags: trunk, v20161127 | |
| 06:38 | Added the "build essential" fix for "No working C compiler found" check-in: da70707573 user: tangent tags: trunk | |
| 06:28 | Released v2016.11.27 check-in: 95de43f25c user: tangent tags: trunk | |
| 05:43 | Header tweak check-in: 6c374cc6f9 user: tangent tags: trunk | |
| 05:29 | Added a link check-in: 638f0605e8 user: tangent tags: trunk | |
| 05:27 | Added a section to examples/README.md showing how to transcribe these example programs into an OS/8 session, then to edit, assemble, and run then within it, all without roaching OS/8. check-in: 83531ee345 user: tangent tags: trunk | |
| 03:26 | Added links from examples/README.md to referenced files in the repo check-in: 050f70179a user: tangent tags: trunk | |
| 03:14 | On systems without palbart, the previous checkin caused a build failure because of a strangeness in the way autosetup handles undefined values. Fixed. check-in: e66b7967af user: tangent tags: trunk | |
| 03:10 | If palbart is found at configure time, the examples are added to the list of things to be built, so that any changes to examples/*.pal can now be automatically built, including renaming *.bin outputs to *.pt. check-in: 9aa3b48ea3 user: tangent tags: trunk | |
| 02:59 | More examples/README.md improvements check-in: de0862ec06 user: tangent tags: trunk | |
| 02:37 | More tweaks to the examples' README check-in: 35a792aa9a user: tangent tags: trunk | |
| 02:29 | Simplified and clarified the "add" example check-in: d55acb82ff user: tangent tags: trunk | |
| 01:41 | Updated binary-glob settings for media/*/*. (Missed these when moving imagefiles to media.) check-in: c23bee4ae1 user: tangent tags: trunk | |
| 01:40 | More improvements to the `add` example and our explanation of it check-in: 8edf63a8f3 user: tangent tags: trunk | |
| 01:14 | Updated the change log check-in: d6a59a3f3a user: tangent tags: trunk | |
| 01:11 | Added a README.md file to the examples directory explaining their use, and included the add.lst file so users don't have to have a PAL-III assembler in order to get the octal dump of the program. check-in: 9bf2da570b user: tangent tags: trunk | |
| 00:29 | Replaced the description of the new build system in ChangeLog.md with a reference to the new README.md file. check-in: efc3e42fee user: tangent tags: trunk | |
| 00:10 | Added a simple PAL-III example program check-in: 414bf01d85 user: tangent tags: trunk | |

| 09:24 | Fixed a bug in the recent $prefix/share/boot changes to "make install" check-in: d2ae60a7be user: tangent tags: trunk | |
| 09:21 | Moved bin/scanswitch into libexec/scanswitch, per FHS. (That is, it is a program that's normally used internally within the software, not something that should be in the user's PATH.) check-in: 3850bf3c78 user: tangent tags: trunk | |
| 09:12 | Renamed bootscripts/ in the source tree to boot/ and installing its contents into $prefix/share/boot according to FHS. check-in: 6a4641388f user: tangent tags: trunk | |
| 09:05 | Renamed imagefiles dir to media in the source tree, and installing its contents to $prefix/share/media to conform to the Filesystem Hierarchy Standard, the official way of doing things on Linux. check-in: 136f311902 user: tangent tags: trunk | |
| 08:40 | . check-in: 5ca3498c8c user: tangent tags: trunk | |
| 08:40 | Whitespace improvements to previous check-in: 041e883a4a user: tangent tags: trunk | |
| 08:34 | Rewrote the readme.txt file as README.md, and wrote a longer version of the brief credits found in that file as AUTHORS.md. check-in: 455d4da843 user: tangent tags: trunk | |
| 07:32 | Renamed all "pidp" references remaining related to the initscript and screen(1) to "pidp8i". Closes [5a50b2b21e] check-in: e8a260f907 user: tangent tags: trunk | |
| 07:10 | The install make target now overwrites the OS and program media in $prefix/imagefiles only when os8.rk05 is missing at install time. You can force a reinstall with "make mediainstall". check-in: a1e313a8af user: tangent tags: trunk | |
| 02:51 | Made "install" target depend on "all" check-in: 2d6ab60acf user: tangent tags: trunk | |

| 23:03 | Fixed some more "PiDP-8" -> "PiDP-8/I" references check-in: 605fe0aa51 user: tangent tags: trunk | |
| 22:48 | Fixed autodependency include for new location of scanswitch.c check-in: e962572e34 user: tangent tags: trunk | |
| 22:44 | Removed commented-out stuff from src/gpio.h and rearranged the header check-in: b3e2b1fb56 user: tangent tags: trunk | |
| 22:41 | The differences in the near-duplicate copy of gpio.h have no effect, so moved scanswitch.c up to the top src level and removed its subdirectory. Closes [0c6553aaa36]. check-in: 2b3b157d60 user: tangent tags: trunk | |
| 16:43 | The new build system now allows building out-of-tree check-in: ce17709249 user: tangent tags: trunk | |
| 16:23 | More ChangeLog work check-in: 596b45e203 user: tangent tags: trunk | |
| 15:50 | Fixed a portability problem in auto.def that prevented some of the recent changes from running on OS X. check-in: 5783b221d5 user: tangent tags: trunk | |
| 15:42 | More work on the changelog check-in: 6565719ef8 user: tangent tags: trunk | |
| 15:26 | Added ChangeLog.md check-in: b0fb73d366 user: tangent tags: trunk | |
| 14:50 | Fixed the upstream bug in the init script where failure to run scanswitch would cause it to try and load 127.script. check-in: 667edea287 user: tangent tags: trunk | |
| 14:41 | Added "/I" after "PiDP-8" references in the initscript check-in: 31ab49e486 user: tangent tags: trunk | |
| 14:39 | Fixed a couple of bugs in the recently-reworked initscript check-in: 8ffac8526b user: tangent tags: trunk | |
| 14:34 | Installing the script formerly known as pdp.sh as $prefix/bin/pidp8i. Between this and the recent chnage to the installer to put $prefix/bin into the non-root user's PATH, you can now type "pidp8i" to enter the simulator. check-in: d7e04ec845 user: tangent tags: trunk | |
| 14:25 | Changed default installation prefix to /opt/pidp8i, partly to address [5a50b2b21e7a] but also so we don't conflict with upstream distro's use of /opt/pidp8. check-in: 95b1f3616b user: tangent tags: trunk | |
| 14:16 | Merged the functional contents of install/*.sh into the make install target. check-in: 0b9be72eeb user: tangent tags: trunk | |
| 13:09 | Renamed etc/rc.pidp8 to etc/pidp8i-init.in, into which template we substitute the absolute install directory name for much the same reason we just did it for the bootscripts. check-in: 65b1b8269a user: tangent tags: trunk | |
| 12:55 | Each of the bootscripts that uses ../ paths to find other files in the system now use absolute paths based on the "prefix" value from autosetup, so that it doesn't matter what your CWD is when you start the simulator. check-in: 53537b0268 user: tangent tags: trunk | |
| 11:34 | Added top-level "make install" target. Closes [b3521c15d6f] check-in: 669621ba0f user: tangent tags: trunk | |
| 10:27 | Silenced the new "clean" targets check-in: 2cb32c646f user: tangent tags: trunk | |
| 10:08 | Removed -lrt from LDFLAGS. It's only needed on old Linuxes, which we don't encounter on Raspberry Pi, and it impacts portability to non-Linux OSes. check-in: 10486f1b1a user: tangent tags: trunk | |
| 10:05 | Replaced Linux-specific nanosecond-resolution sleep calls with portable alternative, with the best local option determined by autosetup. Closes [13d74235b70a]. check-in: a4aebcb04c user: tangent tags: trunk | |
| 09:45 | Replaced the simple Makefile based build system with one based on autosetup, with the following advantages over the prior system: - autodependency generation - better "clean" behavior; added "distclean" target - the serial mod config is now separate from the source code, so mistakes like the one fixed in [a3bd0f7154] don't happen - object files are sequestered in an "obj" subdirectory - scanswitch build is now fully integrated into the main build system; no more recursive Makefiles Partially addresses [b3521c15d6], but there is more in that ticket that this checkin does not provide. check-in: caf26ab564 user: tangent tags: trunk | |
| 02:58 | Commented the SERIALSETUP flag setting back out. (Shouldn't have checked it in like that; that's a local change only.) check-in: a3bd0f7154 user: tangent tags: trunk | |
| 02:33 | Added comments explaining what each of the stock bootscripts does, as well as "echo" messages that send a short explanation of what is happening to the simulator console. Also redefined 7.script in terms of 0.script, so that one is not lead to believe that these two scripts are redundant. The new commenting is especially heavy in these two scripts, as it explains why we need two scripts to provide "one" (actually two!) functions. check-in: 90f8b7c9f9 user: tangent tags: trunk | |
| 01:37 | Added a script for the ASR-33 and added comments to 1.script explaining why they differ, and the conditions required to use the new script instead of 1.script. check-in: 84a0e8d0d8 user: tangent tags: trunk | |
|
2016-11-24

| 08:53 | Added a new SVG DECtape label document. Somewhat unfinished, but usable at this point. check-in: d990ace086 user: tangent tags: trunk | |

| 21:22 | Removed the obsolete SERIALSETUP comment from the top of gpio.c and moved the #include for gpio.h to the top. check-in: d7084b2f87 user: tangent tags: trunk | |
| 08:36 | Added power input and power switch schematic check-in: 5bd9319683 user: tangent tags: trunk | |

| 12:17 | Removed an unwanted +x bit check-in: 0bb1838f17 user: tangent tags: trunk | |
| 12:14 | Added a top-level Makefile, so you don't have to cd down into src check-in: 93d49a25d1 user: tangent tags: trunk | |
| 10:54 | Fixed a bug in 2.script, where a "../" was in the wrong place, preventing TSS-8 from loading correctly. check-in: 869d391320 user: tangent tags: trunk | |
| 10:39 | Made ../bin/scanswitch a top-level dependency, so you don't have to remember to build it separately. The top-level initrc script doesn't behave sanely when that binary is missing. (Symptom: starting pidp8 either gives "0" as a result or you drop into the SimH monitor with a complaint about a missing "127" bootscript, since 127 == "failed to run scanswitch".) check-in: 11b31c536d user: tangent tags: trunk | |
| 09:55 | Applied Ian Schofield's "Display update for the PiDP8" patch from the PiDP-8 Google Group. check-in: 3a85f08639 user: tangent tags: trunk | |
| 09:40 | Creating ../bin if it doesn't already exist. Fossil doesn't store directories, and there's no point checking an empty file in just to create the bin dir. check-in: d0c31db7f9 user: tangent tags: trunk | |
| 09:37 | Made serial mod setting easier to enable check-in: 7c16f39bc8 user: tangent tags: trunk | |
| 09:33 | Upstream version 20151215, containing everything from the tarball except for backups and *.o. Also, all CRLF text files converted to LF. check-in: ec36ee3dab user: tangent tags: trunk, v20151215 | |
