| 23:50 | Add ".decode()" to all uses of self_child.{before,after}. Now everything builds under python3. Closed-Leaf check-in: 9b105fe0f5 user: poetnerd tags: os8-run-python3 | |
|
2019-05-22

| 11:01 | Added a delay value in the STOP mode code path to avoid pointlessly burning host-side CPU cycles while waiting for the user to hit CONT or START on the front panel. Suggested by Ian Schofield. check-in: 46b8e18352 user: tangent tags: trunk | |

| 21:49 | Another systemd workaround for WSL check-in: 91ff28ae9d user: tangent tags: trunk | |
| 20:19 | Fixes to bin/pidp8i for systems that either have no systemd or where (as on WSL) it's broken. In these cases, the script approximates a SysV init script. check-in: 279555ae38 user: tangent tags: trunk | |
| 20:18 | Fix for Cygwin "which" in bin/pidp8i: unlike typical implementations, it gripes on stderr when it can't find a match in the PATH. Sending stderr to /dev/null. check-in: 15389943a9 user: tangent tags: trunk | |
| 18:35 | Added all of the files renamed in [1860880163] to *.in to the Makefile's INFILES variable, so we autoreconf when any of them get touched. check-in: c67bd86630 user: tangent tags: os8-run-python3 | |
| 18:32 | Changed xrange() call to range() in class simh to be compatible with Python 3. check-in: 6d23ecf72c user: tangent tags: os8-run-python3 | |
| 18:25 | The configure script now detects whether Python 2 or 3 is installed, and what its binary is called. If both are installed, it prefers Python 3. This then substitutes the value found into all scripts and module shebang lines that previously hardcoded "/usr/bin/env python". With this move, several files got renamed to *.in, as they previously had no other reason to be treated as Autosetup templates. check-in: 1860880163 user: tangent tags: os8-run-python3 | |
| 16:25 | Updated the discussion of systemd in the top-level README.md file: it was written in terms of the pre-release trunk implementation. We should have made similar changes shortly before release, but overlooked it. check-in: 1f0cad3572 user: tangent tags: trunk | |

| 13:02 | Added the Orientation section to the top-level README.md file and simplified the Prerequisites section following it. check-in: 8f7a8e5e59 user: tangent tags: trunk | |
| 10:34 | Math error fix in ChangeLog.md check-in: 5bd81437e7 user: tangent tags: trunk | |

| 09:40 | Small fix to tools/mkrel. check-in: 07a540166c user: tangent tags: trunk | |
| 09:40 | Released v20190425 check-in: 1999bfb59b user: tangent tags: trunk | |
| 09:26 | Expanded glob in previous to cover v3d.rk05 as well. check-in: 93796e07f6 user: tangent tags: trunk | |
| 09:25 | Updated tools/publish-os8 for the new OS/8 RK05 media names. check-in: 3d717c6324 user: tangent tags: trunk | |
| 08:56 | Changed the systemd service from "Type=oneshot" to "notify" allowing us to use systemd-notify to tell it when the service has successfully started and communicate the screen(1) PID to it. This greatly improves the reliably of systemctl commands on the background service. This solves some of the problems that lead to ticket [ce9ea9c96]. check-in: f9a56691d8 user: tangent tags: trunk | |
|
2019-04-24
| ||
| 11:12 | Adjusted the "make release" process so that the version tag ends up on the release branch, not on trunk, so that "fossil up vYYYYmmDD ; fossil up" results in the user staying on the release branch. If vYYYYmmDD is not the current release, it will switch them to the current release. check-in: 27340aeebd user: tangent tags: trunk | |
|
2019-04-22

| 16:17 | Set Fossil's "pull only" setting on the opened Fossil repo in tools/bosi so users can make local checkins without getting warnings about lacking permission to push. check-in: dcb3d283aa user: tangent tags: trunk | |
| 03:16 | On "make install" the *.script files have their savestate directories changed to $prefix/share/save, rather than depend on %HOME% in that condition. check-in: 5846d941cb user: tangent tags: trunk | |
| 00:14 | Reworked the PiDP-8/I custom SIGINT handler in terms of SIGTERM now that SIMH handles that properly. check-in: f4e7086472 user: tangent tags: trunk | |
| 00:04 | Extracted common elements of most boot/*.script files to boot/common.script.in and applied final changes that allow SIGTERM to work as we expect. Closes [ce9ea9c96]. check-in: dc8791be53 user: tangent tags: trunk | |
|
2019-04-19
| ||
| 08:45 | Updated SIMH again to get distinct SIGTERM handling. (Prior versions treated it the same as SIGINT, which is wrong.) check-in: 61903edc63 user: tangent tags: trunk | |
|
2019-04-18
| ||
| 12:32 | The new "pidp8i stop" implementation failed on a real PiDP-8/I because scanswitch fails when the simulator's running. Switched to a different method for detecting which simulator executable is running. check-in: 10339e6b1a user: tangent tags: trunk | |
| 11:33 | Rewrote "pidp8i stop" to send a SIGINT, wait 2 seconds, then SIGKILL to make use of the new savestate mechanism and hopefully close ticket [ce9ea9c96a]. (Checking it in to try on an actual PiDP-8/I next.) If savestate mode is disabled, we skip the first two steps and go straight to SIGKILL: this could lose data, but until SIMH gets proper SIGTERM support, this is the best we can do. check-in: 98a0b0305a user: tangent tags: trunk | |
| 11:29 | Fixed a few bugs in the new savestate.script: the ON ERROR handler doesn't help, and Ctrl-E CONT would cause a reboot. check-in: 780af010e3 user: tangent tags: trunk | |
| 10:12 | Removed a pointless "ECHO" from the new boot/savestate.script file. check-in: 4810c085f8 user: tangent tags: trunk | |
| 10:09 | Added the --enable-savestate configuration option, conditionally making use of SIMH's SAVE/RESTORE feature and the new Autosetup @include/@define feature to provide parameterized core/register/device state saving and restoration on simulator restarts. check-in: 555b5e5f8d user: tangent tags: trunk | |
| 10:07 | Added @include and @define features to Autosetup's template file processor. This is being pushed upstream as the template-include branch, but we're checking it in here rather than wait for our PR to be accepted because a) we don't want to wait; and b) it might be rejected, and our subsequent checkin requires this feature to work as it currently does. check-in: 3ea0b1ea99 user: tangent tags: trunk | |
| 07:25 | Updated SIMH again: we need the recent fix to ON ERROR handling. check-in: e5ae989411 user: tangent tags: trunk | |
| 06:17 | Fixed something checked into previous: we added $0 to a "chmod -x $(stuff)" line so there was always something to chmod -x if the subshell returned nothing to avoid a complaint from chmod about getting no args, but $0 should always have +x. Changed it to auto.def, something that should never be +x. check-in: 7e0d206df8 user: tangent tags: trunk | |
| 06:15 | Updated Autosetup to tip-of-master (post 0.6.9) in preparation for adding a new feature to it. This changes the syntax for @if expressions, so this checkin includes updates to the two affected boot/*.script files. check-in: 190c00fe14 user: tangent tags: trunk | |
|
2019-04-16
| ||
| 11:51 | "make run" now uses scanswitch to detect lack of GPIO, so it runs the simulator as "pdp8" not "pidp8i-sim" when there is no PiDP-8/I panel. check-in: cd3145ad2d user: tangent tags: trunk | |
| 11:49 | More print() fixes, this time for os8-cp. check-in: e05a907c3f user: tangent tags: os8-run-python3 | |
| 11:38 | Fixed a case where pexpect is giving us a byte string, which annoys Python's regex matcher. Explicitly converting it to an ASCII text string. It's basically a null operation, but it makes Python 3 happy. check-in: 560dc8061a user: tangent tags: os8-run-python3 | |
| 08:24 | scanswitch was returning -1 on no GPIO, which is 255 on macOS at least, which means the test for "no GPIO" in bin/pid8pi wouldn't get hit properly. Returning 127 as that script expects rather than change the script, since the script has established a kind of contract. check-in: 07be964914 user: tangent tags: trunk | |

2019-04-15
| ||
| 07:33 | Merged in the tiny trunk differences relative to the SIMH update accidentally checked in on this branch. Now this branch contains only the Python 2-ism fixes relative to trunk. check-in: 18d667556a user: tangent tags: os8-run-python3 | |
| 07:25 | Updated SIMH to latest upstream. No functional change relative to prior source base as far as I can tell from the commit history since the last update. check-in: fc1b9bc0e9 user: tangent tags: trunk | |
| 06:39 | Opening class simh log files in binary mode to avoid a problem introduced by an unbelievably screwy change in Python 3 vs 2: https://stackoverflow.com/a/5513856/142454 check-in: f921ba10f9 user: tangent tags: os8-run-python3 | |
| 06:33 | Replaced use of dict.iteritems() with items() check-in: 394ecc357c user: tangent tags: os8-run-python3 | |
| 06:27 | First steps to getting os8-run working with Python 3: this is all of the print() calls. (print() is a function in Python 3, not a keyword as in prior versions, so it requires parens around its arguments, always.) This is the start of a new branch because this won't be the only thing needed to get these programs working under Python 3. This is needed on my macOS box because Anaconda Distribution installs Python 3 as "python", which is arguably wrong, but hopefully we can get os8-run and its helper libraries into a state where they run on both versions so this won't matter any more. This checkin *also* accidentally includes a SIMH update, because I was in the middle of the SIMH update and got distracted by fixing the Python 2-isms and accidentally checked the SIMH changes in as well. The SIMH update should have been on trunk only. I'll fix that on this branch a bit down the line. check-in: 05bd569e5e user: tangent tags: os8-run-python3 | |
| 05:40 | Updated bosi script to point at the Fossil 2.8 binary for RPi check-in: 5e51328bc2 user: tangent tags: trunk | |

2019-04-04

| 04:09 | Cleanup of all-tu56.os8 to perhaps head off some other race condition. There was a v3f td128 that blew out because of a mounted dt device -- a heisenbug, not reproducible. I've carefully limited the attachment of the dt device, and explicitly detached it now. check-in: 993ffbdfd3 user: poetnerd tags: trunk | |

| ||
| 07:15 | Another simh.os8_send_cmd() header comment rewrite. check-in: f02a71584b user: tangent tags: trunk | |
| 06:52 | Fixed a couple of locations where the prompt string passed to simh.os8_send_cmd() wasn't being escaped correctly, potentially leading to a breakage in the caller's state machine. check-in: e8a6d0e354 user: tangent tags: trunk | |
| 06:47 | Increased the default timeout to simh.os8_send_cmd() from 30 to 60 seconds in response to a report from a Raspberry Pi A+ user that the media build process can time out when building with the slow TD8E device. check-in: 614c94da4c user: tangent tags: trunk | |
| 06:46 | Rewrote the simh.os8_send_cmd() function comment for clarity and completeness. check-in: 0043a185db user: tangent tags: trunk | |
| 05:47 | Added explicit license grant to HACKERS.md check-in: 5ba94a47d1 user: tangent tags: trunk | |
|
2019-03-21
| ||
| 00:09 | Add error detection for LINE TOO LONG IN FILE to simh.py. Fixes bug f937eb1e32. check-in: 69f9981b49 user: poetnerd tags: trunk | |

| 05:29 | Added a section on CR+LF handling to the CC8 manual. check-in: c8664e03e3 user: tangent tags: trunk | |
| 05:20 | Several small improvements to the CC8 manual check-in: 3cf04448ad user: tangent tags: trunk | |
| 04:29 | Added documentation for putc() and fputc() in doc/cc8-manual.md. check-in: 5a0c639bfe user: tangent tags: trunk | |

| 00:56 | Checkin [a96f0c5f20] missed a location where the old, incorrect "MQO" operator definition in the OS/8 CC8's code generator wasn't changed to the corrected mnemonic, MQA. Bug reported by Ian Schofield. check-in: 9074f0ba54 user: tangent tags: trunk | |

| 11:40 | Fleshed out the discussion of malloc() in the CC8 manual, turning it into a new sub-section, "Fun Trivia: The History of malloc()". check-in: cb743198fd user: tangent tags: cc8-octal-output | |
| 11:12 | Found malloc() in UNIX V7, so added that info to the CC8 manual's poin on "no malloc() in CC8". check-in: 4b64cfdc4c user: tangent tags: cc8-octal-output | |

2019-02-21
| ||
| 12:34 | Updated ChangeLog check-in: a6371d4cad user: tangent tags: cc8-octal-output | |
| 11:55 | Many improvements to the CC8 user manual. Basically, I began re-reading it from the top, improving it along the way with my new understanding of CC8. check-in: 0316450b57 user: tangent tags: cc8-octal-output | |
| 09:08 | Rewrote the history section at the top of the CC8 manual to give a better arc. check-in: 694c027652 user: tangent tags: cc8-octal-output | |
| 08:55 | Updated the CC8 user manual to cover the new octal output default. check-in: 84f718936e user: tangent tags: cc8-octal-output | |
| 08:12 | Squished the bug that prevents this branch from generating code that runs properly: I overlooked the #defines in libc.h which are treated by the compiler as text, not as C integers, so that integer indices emitted in the generated SABR code for calling into LIBC were in decimal but were then interpreted by SABR as octal. If this gave syntactically correct code, it would call the wrong function for every function past index 7. The fact that we never saw it generate syntactically incorrect code merely reflects the fact that we didn't happen to call any functions that used decimal indexes that have no corresponding octal interpretation, a possibility only 1/5 of the time. (e.g. 29) check-in: d5ab8f91d9 user: tangent tags: cc8-octal-output | |

| 12:21 | Merged the CC8 ABSYM and doc changes from trunk into this branch to reduce pointless differences. check-in: f8a2346503 user: tangent tags: cc8-octal-output | |
| 12:13 | Comment improvement check-in: 4693b7fe41 user: tangent tags: trunk | |
| 12:10 | Reverted the changes to the ABSYM declarations in init.h, header.sb, and libc.c, and documented the reason why the declarations in these files do not all match, and why they cannot be packed up into the top of any zero page involving LOADER.SV. check-in: 4dfc549077 user: tangent tags: trunk | |
|
2019-02-19
| ||
| 11:30 | Ian smacked me with a clue-bat: there are *several* zero pages, and their usages do not conflict! Fixed several bits in the CC8 user manual that resulting from this confusion. (This also explains why the discrepancies between INIT and LIBC's globals don't matter: they're in different fields!) check-in: 3ae7245274 user: tangent tags: trunk | |
| 10:44 | First pass at making CC8 emit octal in SABR output only, and to convert the decimal constants in the static SABR code within header.sb, libc.c, and init.h to octal. This also gets rid of all the DECIM directives, since SABR defaults to OCTAL mode. This is on a branch because the result doesn't yet run correctly, and I'm out of time trying to figure out why. check-in: ce071e8713 user: tangent tags: cc8-octal-output | |
| 09:33 | Found yet a *third* copy of the CC8 ABSYM table! These fixups allow the cross-compiler to produce code that links to LIBC properly. That then highlit some differences in the INIT code between header.sb and init.h, the latter of which has both more code and more globals. Mainly fixing this involves packing the new globals up tight against those that init.h shares in common with header.sb and libc.c, but also a change to the docs to reduce the space available to the [f]printf() buffer yet again. check-in: 778e8ff4ec user: tangent tags: trunk | |
| 08:48 | Fixed indents in CC8 init.h and header.sb: I've been fighting with these hard tabs all night, and I'm sick of it. They're space indents now, per HACKERS.md. check-in: e289bdbe25 user: tangent tags: trunk | |
| 08:32 | Merged cc8-libc-zp-reorg branch down to trunk. It appears to be stabilized now. check-in: b0097f70c6 user: tangent tags: trunk | |
| 08:01 | Merged VC8E OPDEF stuff up from trunk to reduce unnecessary diffs Closed-Leaf check-in: 2d4b00518f user: tangent tags: cc8-libc-zp-reorg | |
| 07:58 | Merged VC8E OPDEF feature for CC8 LIBC down from the cc8-libc-zp-reorg fix, where it's out-of-place. check-in: 23f886388e user: tangent tags: trunk | |
| 07:04 | Fixed a CPAGE directive in libc.c that could potentially lead to the LIBC entry point call table being split across pages. check-in: 64f9c6e820 user: tangent tags: cc8-libc-zp-reorg | |
| 03:55 | Checkin [228e1c8b3a] added a comment ending in an exclamation point to HEADER.SB, which is perfectly legal in SABR, but it breaks a hidden contract between the CC0 and CC2 stages of the native compiler, wherein a '!' character terminates the preamble part of the CASM.TX output! This caused un-assemblable SABR output, because everything after that in HEADER.SB got chopped off. (Actually, it was probably treated as the start of the first inline assembly block.) check-in: ae9dda1ecb user: tangent tags: cc8-libc-zp-reorg | |
| 03:31 | Decided to move the LIBC globals previously moved into 10002 thru 10007 to the end of the field 1 zero page, so we can dedicate these 8 locations for user code. Otherwise, user code has no zero page locations they can safely use, which seems rather grabby of us. check-in: ca6257496b user: tangent tags: cc8-libc-zp-reorg | |
| 03:13 | Cherrypicked [52aa88863c] onto trunk, primarily to ensure that those with recent trunk checkouts don't get unexpectedly sent to branch cc8-cleanups. This change is harmless to have in both places. check-in: 0c7432da84 user: tangent tags: trunk | |
| 02:50 | Checkin [1ea9133a37] is incomplete: the CC8 native compiler's HEADER.SB file contains a duplicate of the ABSYM declarations in libc.c, shared between the two CC8 compilers; they need to match! It's not clear to me the consequences of these two not matching, since our tests didn't fail earlier, but there's also no good reason for these to differ. Added comments to reduce the chance of these two pieces of code drifting apart again. check-in: 228e1c8b3a user: tangent tags: cc8-libc-zp-reorg | |
| 02:39 | Added OPDEFs for DILX, DILY, and DIXY instructions to VC8E, shortly to be used within CC8's dispxy() LIBC routine. check-in: 281ab90846 user: tangent tags: cc8-libc-zp-reorg | |

| 01:31 | Grammar fix check-in: b2f266258f user: tangent tags: cc8-libc-zp-reorg | |
| 01:23 | Moved [f]printf() buffer down into the otherwise sparsely used zero page, and rearranged the constants previously declared there to make better use of the space available. This then opens another half-page of space for the stack. Updated docs to cover all of this. EDIT: This is the start of a new branch because this checkin breaks some things, and some of the subsequent checkins destabilize CC8. I'm moving it to a branch until all that's fixed. check-in: 1ea9133a37 user: tangent tags: cc8-libc-zp-reorg | |

| 19:12 | Added more detail about file I/O limitations to the LIBC user documentation section of the CC8 manual. (What used to be the "stdio" section is now broken up into several sections at the same level.) check-in: 23f92ab553 user: tangent tags: trunk | |

| 05:27 | Passing --disable-cc8-cross now effectively sets --disable-os8-cc8. That wasn't necessary before, since we were distributing a pre-built version of the native CC8, but now that we're building it from source, we need the cross-compiler to produce cc8.tu56. check-in: ff7ab04cc3 user: tangent tags: trunk | |

| 05:03 | Decided to put the "1" back at the beginning of the addresses for the UDF ranges in the CC8 manual: it's a pretty good bet that the UDF will remain field 1 despite LOADER jiggery-pokery. check-in: d166926273 user: tangent tags: trunk | |
| 04:51 | Changed all of the bare CRs in the output from the final stage of the OS/8 CC8 (CC2.SV) to CRLFs. This solves a problem where PIP couldn't read the input file correctly, preventing us from using os8-cp in ASCII mode to copy the CC.SB file out to examine it in a civilized text editor. check-in: 529c0ee697 user: tangent tags: trunk | |
| 04:46 | Changed all uses of fprintf() in src/cc8/os8/p8.c that don't use printf() format specifiers to fputs() instead, saving 200 core memory locations due to the lower amount of stack manipulation required to call a straight function with a single parameter. check-in: 0b3919909f user: tangent tags: trunk | |

| 01:03 | src/cc8/os8/header.sb was using size-4 hard tabs to emulate size-8 hard tabs, causing ugly output when you TYPE CC.SB or HEADER.SB on the OS/8 side. Changed these to size-8 hard tabs. Also added a Vim modeline to the top of the file to ensure that Vim (at least) will preserve our intent here. check-in: e7dd3c2c38 user: tangent tags: trunk | |

| 09:13 | Fixed a bug introduced by [c20811f34c] affecting uses of printf "%d": the implementation wasn't passing "10" as the new radix parameter. It wasn't caught because CC8, being a K&R dialect, doesn't need or support function prototypes. check-in: a230f38ad3 user: tangent tags: trunk | |

| 04:30 | Fixed some nonstandard OPDEFs in the SABR code generated by CC8: its "MQA" is normally called "ACL", and its nonstandard "MQO" opcode is what's normally called "MQA". check-in: a96f0c5f20 user: tangent tags: trunk | |
| 04:18 | sprintf() now returns -1 when it hits an unknown format specifier, as cppreference says it should. This is actually smaller than the prior code, which incorrectly returned the number of characters written so far and then failed to terminate the output string. cppreference doesn't say we should terminate the output string in this condition, but the error return is enough to clue the user in that they shouldn't use the output string. check-in: 7e5e3a226d user: tangent tags: trunk | |

| 03:31 | The CC8 LIBC's itoa() function now has a radix parameter, like the function of the same name common in Windows and DOS C compiler standard libraries. This also effectively exposes the previously internal itoab() function, itoa() basically acting as a wrapper for it for bases other than 10 and for positive values in base 10. That is, the only difference between the two is for negative values in base 10. check-in: c20811f34c user: tangent tags: trunk | |

| 20:30 | Another cc8/cross update from Ian Schofield. Addresses bug a4123bb743, making the cross compiler at last allow typed function declarations. cc8 now builds silently with -Wall. Supporting struct in the pdp-8 target had a storage management bug that is now fixed. The void type is now added to cc8. The resulting native C compiler for OS/8 is unchanged -- bit for bit identical, because that code does not use any of the enhancements to the cc8 cross compiler. check-in: dc687b9f08 user: poetnerd tags: smc85-cc8 | |

| 12:57 | Fixed [b33f80acd8]: the Ctrl-E exit to the SIMH command prompt causes our new SIGINT handler to be called, which was not only turning off the LEDs but also shutting down the GPIO thread. That means that on sim re-entry, we'd refuse to turn the LEDs back on because the GPIO thread is no longer running. The fix is to turn LEDs off conditional only on whether the PiDP-8/I extensions are enabled, but to stop the GPIO thread only if we're going through the exit(3) path on handling SIGINT. check-in: 85596d132e user: tangent tags: trunk | |

| 04:54 | Checking for error return from a read(2) call in d8tape to squish a complaint from GCC on Ubuntu 18.04. check-in: a6aa94eee4 user: tangent tags: trunk | |
| 04:49 | Specifying "Python 2" in the configure script messages: Ubuntu ships Python 3 by default, so when we claim "Python isn't installed" because Python *2* isn't available, it was jarring. check-in: d8244b866f user: tangent tags: trunk | |
| 02:51 | Removed the "@builddir@/" prefix on the call to os8-cp in Makefile.in: relative paths work even in out-of-tree builds, and this comes from os8-cp.in, so it's definitely in the build tree. check-in: c237120a73 user: tangent tags: trunk | |
| 02:50 | Fixed some drift in the INFILES definition in Makefile.in check-in: 670a6a98a0 user: tangent tags: trunk | |
| 02:40 | Raised the timeout on initial SIMH startup again, from 5 to 10 seconds. We still occasionally get pexpect timeouts on busy systems. Also, we've now seen it on a single-core FreeBSD VM while the host is busy running test-os8-run and such. check-in: 76ff6246c9 user: tangent tags: trunk | |
| 02:36 | Changed all the Python script shebang lines to use /usr/bin/env so they work on systems where Python is not in /usr/bin, such as FreeBSD, where it's in /usr/local/bin due to its being a non-core package. check-in: 91c645ba93 user: tangent tags: trunk | |
| 02:25 | Changed use of "type -p" to "which" in tools/mmake for portability to FreeBSD, whose /bin/sh doesn't understand that. It's in Bash and probably in ksh93, but we don't want to require that on FreeBSD. check-in: 72a6435832 user: tangent tags: trunk | |
| 02:21 | tools/mmake now tries harder to find the bin dir for the corecount call. This is needed on systems where $0 isn't set to an absolute path when a program is called via the PATH, like FreeBSD. check-in: 1124a3e512 user: tangent tags: trunk | |
| 02:14 | tools/mmake now runs "gmake" if found in the PATH instead of "make". This is required on FreeBSD since our Makefile.in isn't BSD make compatible. On macOS, /usr/bin/make is an older version of GNU make, so if gmake is available, it must've been installed separately, so we can assume the user wants us to use the newer version. check-in: 8146518605 user: tangent tags: trunk | |

| 01:58 | Moved the Perl test up in auto.def: tools/version is called before the prior location, which we thought was a good place to put it since it's just before the Python test. check-in: b0fb14bedb user: tangent tags: perl-existence-check | |
| 01:57 | The configure script now checks for Perl in the path. It's required by tools/version, tools/mkbootscript, and tools/test-os8-run. check-in: de63545335 user: tangent tags: perl-existence-check | |
| 01:43 | The configure script now tells how to get "pip" on Debian type systems. check-in: d3c0d7536f user: tangent tags: trunk | |

| 14:45 | If the pidp8i script doesn't detect the PiDP-8/I front panel via scanswitch, it falls back to our new pdp8 alias to suppress the GPIO thread. You can thus install the PiDP-8/I software on a systemd based Linux distro and say things like `pidp8i start` and get our new HLT handling, skip the complaints about no GPIO, etc. check-in: 8848227626 user: tangent tags: trunk | |

| 10:48 | Typo fix check-in: 0514b6a5e4 user: tangent tags: trunk | |
| 10:26 | The optimized PRINTS routine requires that AC point at the word *before* the string you want it to print, so we were printing "ELLO, WORLD!" The prior bug with mkbootscript masked this. check-in: 59b81c7034 user: tangent tags: trunk | |
| 10:23 | Set 8th bit on the ASCIIZ strings in pep001.pal, in case it's used with a terminal that cares about this, such as an ASR-33. check-in: 397c6d8901 user: tangent tags: trunk | |
| 10:21 | The pep001.pal program could hang in the TSF loop on writing the initial "ANSWER: " leader if the terminal device isn't prepared to receive characters. Added a "TLS" to send a null character to kick things off. This eats up the one remaining word left in PAGE 1! check-in: 15e91ae82b user: tangent tags: trunk | |
| 10:19 | Fixed a bug in tools/mkbootscript that caused it to write a SIMH "dep" command for only the first word in an assembly file data table, currently used in our examples for ASCII terminal output strings. This caused our "HELLO, WORLD!" demo program to do nothing useful, and for the "ANSWER: " leader from pep001.pal to be truncated to "A". check-in: 2702b89257 user: tangent tags: trunk | |
| 08:30 | If you run the simulator via the new "pdp8" name, we revert the change to the behavior of the HLT instruction: it drops you to the sim> command line instead of halting the CPU in expectation that the user will then poke around with the CPU state or hit CONT via the front panel. check-in: 2b00fa32cd user: tangent tags: trunk | |
| 08:24 | Set 8th bit on ASCIIZ characters in the PDP-8 assembly "HELLO, WORLD!" demo program: some terminal configurations may require it. check-in: 174d0dc11e user: tangent tags: trunk | |

| 20:38 | The PRINTS routine in examples/hello.pal was not Rick Murphy's optimized version that we're shipping in examples/routines/prints.pal. Updated it. Also fixed the header comment so that the resulting boot script doesn't have a dangling clause in its startup message. check-in: a4075c7cd0 user: tangent tags: trunk | |
| 18:20 | Updated the references to "mkos8" in doc/class-simh.md. There are still two references there for historical reasons, but the bulk of the text now refers to os8-run instead. check-in: bcf566411e user: tangent tags: trunk | |
| 18:07 | Rethought the policy on overwriting binary media: although it made sense to allow the new RK05 disk file names to merge with the old, this step also overwrites the boot scripts when that happens, and those may have user changes as well. Therefore, the new policy is that if *any* IF=0 default disk image is found, past or present, we skip mediainstall. You have to choose to run it by hand in that case, or follow the manual merge steps from README.md. check-in: 685d583d5a user: tangent tags: trunk | |
| 17:53 | Changed a bunch of "os8v3d*.rk05" references to their equivalent and current names. check-in: c2fc076dcc user: tangent tags: trunk | |
| 17:51 | Changed "make install" so that it skips "make mediainstall" based on the existence of v3d.rk05 rather than local.tu56 so that we merge our new media with v20171222, as that release was able to merge its os8v3d-* with the os8.rk05 of prior releases. This does mean the prior release's local.tu56 and pristine source tapes can get overwritten, but those weren't supposed to be changed by the user anyway. We don't wan't people doing "make install" and not understanding why their "new" system behaves just like the old one. check-in: 384bf04b34 user: tangent tags: trunk | |
| 16:22 | Changing boot scripts via IF + SING_STEP now detaches all devices, shuts down the GPIO thread, and re-launches the simulator with the new script rather than just call "do SCRIPTNAME" in order to get a fresh simulator configuration, free of conflicts. The case that prompted the need for this is switching between boot scripts that assume the tape controller is TC08 to one that assumes TD8E, or vice versa. The only other way we could solve this is to write "detach" commands at the top of every boot script to undo everything done by every other possible boot script.
