| 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 | |
| 09:29 | update template files to my most recent versions - the initial commit version would not build Closed-Leaf check-in: 43ed427653 user: tony tags: simh-update | |
| 09:04 | created branch for merging updated simh files from github commit 5ced037b4bdbf36e04b78bcfde780b07871babb5 on 2016/12/19 check-in: a0a4ae25d3 user: tony tags: simh-update | |

| 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 | |

| 17:24 | Moved the new "disable competing services" install step above the "enable pidp8i service" step, and using parallel methods to enable the latter as we do to disble the former. check-in: cbbee9c080 user: tangent tags: release | |
| 17:20 | Disabling the 'deeper' and 'pidp8' services on 'make install' in case they're present, in which case they'll fight with our service. Closes [a1cd66327f]. check-in: 8060e0fbd2 user: tangent tags: release | |
| 17:11 | Appended gpio to the supplemental group list of @INSTUSR@ if group gpio is present on the install system, as it will be on the Raspberry Pi. This is needed for end users who build and install the software under a different account than the default 'pi' user or a derivative, as we do with user pidp8i in the binary installation media. Closes [56397a0c55] check-in: 4f68bc260d user: tangent tags: release | |

| 00:07 | Updated the FORTRAN item in the previous ChangeLog.md, on finding that both problems affected FORTRAN IV, not one affecting FORTRAN II as I supposed. check-in: b8f9c278e8 user: tangent tags: release | |

2016-12-19

| 12:52 | Background fix (again) check-in: 40d4a0a373 user: tangent | |
| 12:48 | Border and background improvements for VTEDIT diagram check-in: 6cb84eb396 user: tangent | |
| 12:44 | Layer fixes to previous check-in: e799bb8810 user: tangent | |

| 08:45 | Small fix to previous check-in: a70a030e1c user: tangent | |
| 08:43 | Put guards on the new reboot/poweroff switch combos to make them not run when the PiDP-8/I panel isn't present. check-in: f4ce8086b8 user: tangent | |
| 08:41 | Added missing etc/sudoers.in check-in: 2809cef764 user: tangent | |
| 07:44 | Swapped the meaning of Sing_Step + Sing_Inst + Start from poweroff to reboot, as the mnemonic seems to speak of "restart" rather than "shutdown and power off." Then instead of reassigning the + Cont combo to shutdown, gave it + Stop. check-in: 855e1e9883 user: tangent | |
| 07:33 | Moved the Sing_Step + Sing_Inst + X switch combo detectors outside the block that turns Sing_Step into a momentary switch in software. With the tests inside that block, the exact order of switch activations matters, but we want the combinations to take effect regardless of switch close order. check-in: 2ec003caf0 user: tangent | |
| 07:28 | Replaced many of the bare constants used for switch detection in the simulator with the new GPIO SSn_* constants. check-in: 6acd6b1416 user: tangent | |
| 06:22 | Added a series of #defines for switchstatus masks check-in: 656b4cc0f1 user: tangent | |
| 06:07 | Worked around a race condition in test.c that caused it to fail to start if the GPIO thread didn't start fast enough, thinking that the lock had not been acquired. (The proper fix would be a mutex or semaphore, but...) check-in: 510d648410 user: tangent | |
| 05:44 | Replaced the calls to shutdown(8) and reboot(8) with calls to /bin/systemctl, the proper way to do such things on modern Ubuntu. Then, added those commands to /etc/sudoers.d for the install user so that the user can run those commands via pidp8i-sim without superuser privileges. Closes [0584a955f5]. check-in: d1ca449bfa user: tangent | |

| 12:56 | Copied Rick Murphy's modified VTEDIT-for-VT100 stuff to SYS: on the OS/8 disk image, and added a slightly modified version of VTEDIT.DC (docs for the editor) given by Rick on the mailing list. check-in: 9fdbd48f6f user: tangent | |
| 03:02 | Ran SQUISH on both halves of the OS/8 disk image, in case the previous edits fragmented it. check-in: 67edb22601 user: tangent | |
| 02:58 | Copied FORLIB.RL over from Rick Murphy's advent.rk05 disk to os8.rk05 to solve an issue reported way back in April on the mailing list: https://groups.google.com/forum/#!searchin/pidp-8/fortran%7Csort:relevance/pidp-8/VACP-EhC-L8/omae17ZSBQAJ check-in: cdd0f01b45 user: tangent | |
| 02:55 | Copied FRTS.SV from Rick Murphy's advent.rk05 disk over the top of the broken one that came from upstream on os8.rk05. Now ".R FRTS" doesn't just hang. Closes [12dd9869d0] check-in: c696fa9b04 user: tangent | |

| 23:52 | Merged BOOTDIR fix from trunk check-in: beb62e8230 user: tangent tags: no-lamp-simulator | |
| 23:51 | Reverted the renaming of pdp8_cpu.c.in. The removal of the references to @ABSPREFIX@ wasn't the total removal of all autosetup-provided values. There was still a use of @BOOTDIR@, at least. check-in: 9adbcad6b9 user: tangent | |
| 22:27 | Merged in trunk changes check-in: 72ad17c733 user: tangent tags: no-lamp-simulator | |
| 22:15 | The recent change to autodetect available C compiler flags accidentally dropped out -D_GNU_SOURCE, which broke the build for sim_fio.c. check-in: af1e357fb1 user: tangent | |
| 20:48 | Removed a stray "RKB0:" in examples/README.md. The rest of the commands don't expect this file to be on the second slice. check-in: 0a869556c4 user: tangent | |
| 19:53 | Added BASIC section to examples/README.md check-in: ad15ce98aa user: tangent | |

| 06:12 | Fixed a few problems with the "make clean" and "make distclean" targets check-in: 0dbecf027d user: tangent | |
| 06:09 | Conditionally added several GCC-specific flags to CFLAGS to better match how upstream SimH 4.0 is built. Also made some of the existing flags conditional, in case Clang drifts away from GCC-compatibility. check-in: cf898b1ffa user: tangent | |

| 20:08 | Improved comments in boot/5.script check-in: 676a0faae1 user: tangent | |
| 19:53 | Added assembly language version of 5.script as ac-mq-blinker.pal check-in: 91297147ab user: tangent | |
| 05:09 | Diked out the USB media mount/unmount features added to the buildroot version, since it isn't necessary with my binary images. In fact, if you *don't* use the original buildroot custom OS, it doesn't work at all. Since I don't want to use buildroot, we might as well free these front panel switch combos up for other purposes. check-in: d13004a8f5 user: tangent | |
| 04:49 | The /dev/gpiomem mmap/unmap pair now acquires a lock on the device so that two LED-manipulating programs cannot grab the device at once. This prevents multiple pidp8i-sim simulators or combinations of simulator and pidp8i-test from fighting over the LEDs. We *do* allow scanswitch to run in parallel with these other two, since that's harmless. Closes [9390414809] check-in: f26340b636 user: tangent | |
| 02:51 | Minor adjustments to AUTHORS.md check-in: 81ff3fa674 user: tangent | |
|
2016-12-08
| ||
| 03:25 | If the simulator fails to open /dev/gpiomem or to mmap() the GPIO peripheral into its address space, it now disables the PiDP-8/I front panel functionality so that we don't get phantom switch activations on non-Pi systems. Basically, it reverts to nearly-stock SimH behavior. This lets you build and test off the Pi, on a faster system, and deploy to the Pi once you've got something worth testing on the actual hardware. Closes [0a89046aab5]. check-in: 1486a28eb2 user: tangent | |
| 03:07 | The init script now drops superuser privileges before executing any screen(1) command so that the simulator and its attached screen session are owned by the user who configured the software, which is presumably the one who will be trying to run it. Similarly, the bin/pidp8i script now no longer runs screen(1) via sudo. The practical upshot of this is that the only remaining commands that you have to run via sudo are the ones to start and stop the simulator, and that's only because service control feels like it should belong to root. Closes [aa4c9ba77]. check-in: 477b1549b6 user: tangent | |
| 02:28 | The binary media images now install as group-writeable by the primary group of the user who ran the configure script, so that you can run the simulator against the installed images as a regular user and still be able to write to the installed media. check-in: 023ef97693 user: tangent | |
| 01:56 | Prior checkin didn't work because setcap doesn't accept more than one executable name. check-in: c741e0ffe0 user: tangent | |
| 01:52 | Applying the "let user program increase its priority" setcap fix to bin/pidp8i-test as well. check-in: 88c2045e7d user: tangent | |
| 01:49 | Applied the /dev/mem -> /dev/gpiomem change check-in: 12f1c46bcd user: tangent tags: no-lamp-simulator | |
|
2016-12-07
| ||
| 16:26 | The gpio-nls module now uses /dev/gpiomem instead of /dev/mem, so it can run without sudo, which is a doubly good thing because sudo resets the path so that the normal installation location's bin subdir isn't included. check-in: f1572cc816 user: tangent | |
| 16:01 | Got rid of STMAX as a separate constant, since it suffices to just reuse MAX, with the understanding that MAX < 1024 now, so that the subtotal rollover point is <= 1024. A separate constant makes sense when MAX is much smaller than STMAX, but they're so close now it's pointless have both. Closed-Leaf check-in: 8dea8cc325 user: tangent tags: pep001.pal-stripped-ascii | |
| 15:54 | Dropped an unnecessary CLL in SAPRT: we aren't rotating bits any more, so we don't care if the link is set. check-in: 15e5c13878 user: tangent tags: pep001.pal-stripped-ascii | |
| 15:52 | Moved the SANEXT label down an instruction: it was on a redundant instruction with respect to the next iteration of that loop. check-in: 9b1e789139 user: tangent tags: pep001.pal-stripped-ascii | |
| 15:33 | Squeezed two more words from SAPRT by using the PDP-8/E's SWP instruction instead of two RTR's, and using the MQ for storage instead of a named core location for temporary storage. check-in: b1903a5e57 user: tangent tags: pep001.pal-stripped-ascii | |
| 14:59 | Merged trunk changes check-in: 8b7ba265bf user: tangent tags: pep001.pal-stripped-ascii | |
| 14:59 | Added examples/*.err to the list of things the clean target removes. palbart normally removes these for you on a clean build, but it is possible that someone could say "make clean" just after a failed build and expect these files to be gone, too. check-in: ab1e41e4a0 user: tangent | |
| 14:57 | When assembling with palbart, if the assembler returns an error we now cat the *.err file to the screen for you, so you don't have to switch editor buffers to see what error(s) it caught. check-in: 1bb0304c3d user: tangent | |
| 04:54 | Binary OS images now use zip format to match the Foundation's docs, and so Windows users don't need 7Zip or similar. check-in: 058ddc4488 user: tangent | |
| 03:23 | Copied gpio.[ch] over from the no-lamp-simulator branch as src/gpio-nls.[ch] for use by pidp8i-test, allowing the tester to run properly when built from this branch, too. Re-tagged as v20161206. check-in: 7a21d3f627 user: tangent tags: v20161206 | |

| 22:56 | Moved a hyperlink inline in the release process doc check-in: 23b058bb45 user: tangent | |
| 17:12 | Rewrote PRINTS in pep001.pal to accept a subset of the "stripped ASCII" encoding produced by the assembler for TEXT directives. It is untested, and so far, it's 8 instructions longer than the ASCIIZ implementation, so I don't want to commit it as the main version even if it does work. I'm saving it as a branch in case it's useful later, and possibly someone will find a way to bum those 8 extra instructions back out. check-in: 80fe276c70 user: tangent tags: pep001.pal-stripped-ascii | |
| 16:03 | Extracted updated PRINTS routine from examples/pep001.pal check-in: 45501a8440 user: tangent | |
| 15:05 | Replaced the space at the end of the "ANSWER: " string constant since the previous checkin bought us two instructions at the end of page 1. check-in: e1e4f9fbe7 user: tangent | |
| 15:04 | Dropped two unnecessary CLAs from examples/pep001.pal: DECPRT leaves AC = 0 and SHOWST calls that at its tail end, so removed the CLAs following the two calls to SHOWST. (Patch by Rick Murphy.) check-in: a9330964a2 user: tangent | |

| 09:03 | Carved two lines off of the OS/8 BASIC example check-in: 1858541d03 user: tangent | |
| 08:15 | The process for creating a bootable Raspbian image for the PiDP-8/I involves removing SSH host keys. Since the stock OS apparently only does this on the first actual boot, I've added a step to the init script to regenerate these keys if they're missing. Ideally, I'd find a way to re-trigger the OS's own key generation process, but a whole lot of grepping has failed to turn it up. check-in: 1072cdb004 user: tangent | |

| 10:44 | Minor improvements to the init script check-in: d50cef7245 user: tangent | |
| 10:15 | Added several missing *.in dependencies to the Makefile target. The most critical are those under src, since editing the *.c.in file should force a reconfiguration, re-generating the *.c file from it. check-in: 0fc0e814b1 user: tangent | |

| 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 | |

| 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 | |

| 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 | |

| 05:17 | 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 | |
