21:43
Added some forward references within the top-level readme, for those reading it online. check-in: c5b1607ded user: tangent tags: trunk
2019-09-03
00:01
Added prism.js, shortly to be used by the skin for syntax highlighting in repo code displays. check-in: 27d9da9dbe user: tangent tags: trunk
2019-08-18
00:57
Tightened up the Fossil vs Git stuff in HACKERS.md, added a bit more Fossil help, added some links to external help, and reorganized the top level sections to flow better. check-in: ce1fca0017 user: tangent tags: trunk
2019-08-17
23:15
Merged the use of libbcm_host from trunk with Oscar's new GPIO pull up/down setup code to get the best of both worlds. This requires a version of libbcm_host that was only just released: https://github.com/raspberrypi/firmware/issues/1161 Leaf check-in: 1eee471981 user: tangent tags: pi4-gpio-clean
2019-08-16
00:50
Changed all references to "FOCAL 69" to "FOCAL,1969", and linked to the new "[Running FOCAL,1969]" wiki article which explains why this naming difference matters. check-in: d10da9f386 user: tangent tags: trunk

22:49
Updated the docs talking about Fossil 2.x binaries now that Buster is out, shipping Fossil 2.9. check-in: 062d059f8a user: tangent tags: trunk
00:22
Added support for Pi 4 GPIO, based on code the Raspberry Pi Foundation published: https://github.com/RPi-Distro/raspi-gpio/commit/80fa7d04eafb3ea34fc6f2d32de5f1873b5fb369 This check-in is based on a version of gpio-common.c.in posted to the PiDP-8 Google Group by Oscar Vermeulen, which is why we're giving him credit for this check-in, even though I (tangent) have done quite a lot of changes to that code, mainly to match the existing code style. This is a branch because it conflicts with the current tip-of-trunk and because it's not yet tested on a Pi 4. It is unknown whether this branch will end up overriding the method we're using on trunk for Pi 0-3 or if we will instead wait for the Foundation to publish a new libbcm_host that obviates some of what this check-in does.

Create new branch named "pi4-gpio-hack" check-in: 9a444fb597 user: tangent tags: pi4-gpio-hack
2019-08-13
04:58
Clarified the tarball unpacking command in the top-level README.md. check-in: 74ae8b2240 user: tangent tags: trunk
2019-08-11
03:37
Assorted improvements to the top-level README.md file. check-in: c3f1846968 user: tangent tags: trunk
2019-08-09
10:57
Added link to "Fossil Versus Git" article from our HACKERS.md, near where we are making similar (but less detailed) arguments. check-in: 1be7a95d8e user: tangent tags: trunk
09:02
Updated Autosetup. This is mainly an update to Jim Tcl 78 check-in: bc107cc50c user: tangent tags: trunk
00:39
Removed +x bit on files that don't need to be executable check-in: 453bb7afc7 user: tangent tags: trunk
2019-08-08
08:40
Fixed a documentation bug (./configure --lowercase=none is actually =pass) and did a clarity pass on the surrounding text while in there. check-in: 87616c6220 user: tangent tags: trunk
2019-08-03
23:36
Small fixes to previous for the non-Pi case. check-in: b40c2f5f83 user: tangent tags: trunk
23:31
Calling bcm_host_get_peripheral_address() in libbcm_host.so from libraspberrypi-dev instead of the hard-coded version we had before, which was apparently copied from old versions of the Pi developer docs. Now following the current advice: https://www.raspberrypi.org/documentation/hardware/raspberrypi/peripheral_addresses.md Doing this in the hopes that it fixes the compatibility problem with the Pi 4, but if it doesn't, this is probably the correct thing anyway. Tested with a Pi 3B+, so checking it in straight on trunk. check-in: 55cfea5027 user: tangent tags: trunk
2019-07-21
10:13
Simplified the logic in tools/mmake for detecting whether GNU make is called as "gmake" or as just "make". check-in: fc2a0c1c8f user: tangent tags: trunk
2019-05-22
19:19
Removed the handler for "freeze display on STOP" to match Ian Schofield's original "LED dithering" ILS-lite patch for the Pi Zero. Leaf check-in: 7d1cd49fe2 user: tangent tags: pi-zero-ils
11:58
Untested application of Ian Schofield's LED dithering patch, which replaces the NLS mode with a different PWM-based incandescent lamp simulator scheme than either his original ILS or my "new ILS," intended to give much the same effect while using less host CPU power, so that it can run on a Pi Zero. This checkin is very different from the patch as posted on the mailing list, but I *think* it implements the same core algorithm. It's untested because while I have a PiDP-8/I front panel and a Pi Zero W here, I don't want to tear my PiDP-8/I apart to put the two together. That's and many other reasons are why this is on a branch. check-in: de6d1f5a43 user: tangent tags: pi-zero-ils
11:03
Removed an obsolete FIXME comment check-in: 0d1ada3484 user: tangent tags: trunk
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
2019-05-18
20:31
Added link to Balena Etcher from doc/OS-images.md check-in: 78e77bf3f0 user: tangent tags: trunk
20:30
Another clarity pass on doc/OS-images.md check-in: 824c33fa11 user: tangent tags: trunk
20:29
Assorted tweaks to doc/OS-images.md check-in: b20ee14442 user: tangent tags: trunk
2019-05-17
11:25
Clarified the "motivation" at the top of doc/os8-run.md check-in: ecff080a2b user: tangent tags: trunk
2019-05-15
18:35
Grammar fix check-in: 0a67aee2f9 user: tangent tags: trunk

Clarity tweak to the --enable-savestate doc check-in: 8a91c99445 user: tangent tags: trunk
2019-05-11
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. Leaf 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
15:33
URL update check-in: 89e22f5975 user: tangent tags: trunk
15:33
Merged in trunk changes check-in: 19490adbd4 user: tangent tags: os8-run-python3
15:17
Assorted small updates to doc/class-simh.md check-in: b4b89f2f1e user: tangent tags: trunk
13:03
Added TECO Pi macro creation credit to bin/teco-pi-demo. check-in: 57ccbf54aa user: tangent tags: trunk
2019-04-26
16:19
Updated to latest Autosetup master: my @include and @define features were merged upstream, and it improves syntax error detection for @if. check-in: fb4e965288 user: tangent tags: trunk
2019-04-25
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
10:29
Added -y to an apt-get command in tools/bosi check-in: 04cce6c025 user: tangent tags: trunk
09:46
Merged trunk changes for v20190425 into release branch Leaf check-in: 2e08e8ff1a user: tangent tags: release, v20190425
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
