2020-01-27
17:45
Allow SCREEN_MANAGER=none mode to work under systemd: don't redirect commands through systemctl if isatty. check-in: 31a8e26aa0 user: tangent tags: screen-mgr-none-dtach
17:33
Fixed a whitespace bug in the method dtach mode uses to extract the PID for passing to systemd, if present. check-in: 021f889a86 user: tangent tags: screen-mgr-none-dtach
17:32
Removed -E mode from the dtach call in the pidp8i script: we *want* to be able to detach from the terminal. This should not interfere with terminal escapes from the simulator since dtach should be scanning for this only from the terminal *input* side. If someone comes up with a reason that SIMH or the simulated software needs Ctrl-\ for its own purposes, we can change the detach character to something else. check-in: e13467f10a user: tangent tags: screen-mgr-none-dtach
17:27
Installing a default etc/pidp8i.rc file if it doesn't already exist so users will have an example to work from. check-in: b9f771a73b user: tangent tags: screen-mgr-none-dtach
17:26
Changed -A mode in the dtach command in bin/pidp8i in SCREEN_MANAGER=dtach mode to -n: when running under systemd, there is no controlling terminal, so there is nothing to detach *from*. tmux and screen handle this automatically, but dtach has to be told. check-in: a7e811e6bf user: tangent tags: screen-mgr-none-dtach
2020-01-26
21:48
Whitespace fix check-in: e7411b636d user: tangent tags: screen-mgr-none-dtach
21:47
Markdown fix check-in: 936d63bd1c user: tangent tags: screen-mgr-none-dtach
21:46
Improved explanation of new SCREEN_MANAGER=dtach option. check-in: 02377ee417 user: tangent tags: screen-mgr-none-dtach
21:34
URL fix check-in: 07a0439868 user: tangent tags: screen-mgr-none-dtach
21:33
Tweaked a potentially confusing message output from "pidp8i stop". check-in: d044732095 user: tangent tags: screen-mgr-none-dtach
21:32
Added the SCREEN_MANAGER=dtach option check-in: dd5ad30192 user: tangent tags: screen-mgr-none-dtach
20:53
Added the SCREEN_MANAGER=none feature, being an alternative to "make run" for running the simulator hard-attached to the local terminal while still making use of the media in the install tree, rather than the pristine pre-install versions. check-in: b6e58203de user: tangent tags: screen-mgr-none-dtach
2020-01-14
15:26
Fixed an incorrect line break in os8-run.md check-in: 059aac0685 user: tangent tags: trunk
2019-10-21
04:34
Fixed some heading levels in the top-level README.md file check-in: a8298c604e user: tangent tags: trunk
2019-10-05
11:27
Merged pidp8i-tmux down to trunk check-in: be3a3d9bd0 user: tangent tags: trunk
11:17
Merged usb-floppy down to trunk check-in: 348a62931c user: tangent tags: trunk
2019-10-04
18:53
Move README.md runtime configuration section below compile configuration section. Closed-Leaf check-in: 3d0d5dc385 user: ryan tags: pidp8i-tmux
18:12
Added option to allow the pidp8i screen session to be managed by tmux(1) instead of screen(1). This introduces a new optional sourcable runtime configuration script, pidp8i.rc. check-in: 3df1c859f7 user: ryan tags: pidp8i-tmux
16:38
Added udev rules to allow mounting media from disks on USB floppy drives. Closed-Leaf check-in: b33153775e user: ryan tags: usb-floppy
2019-09-22
08:48
Added "bsdmake" to the list of "make" flavors checked for by tools/mmake. The PiDP-8/I build system won't build with BSD make, but these scripts may be used in other projects, and BSD make does understand the -j option. check-in: eec38b61e1 user: tangent tags: trunk
08:46
Quoted an argument to "test -z": if the arg is empty, it must be quoted to give an empty argument rather than just disappear in the shell processing. check-in: 8eab979d44 user: tangent tags: trunk
2019-09-10
22:51
Explained why tab size 4 with spaces is important in the C style guide. check-in: 530ae2d758 user: tangent tags: trunk
21:47
Added forward link to info on starting OpenSSH on a Pi within the top-level README.md file. check-in: 579e02166b user: tangent tags: trunk
21:45
Removed a few stale references to Zip file source tree downloads in the top-level README.md: we removed those links some time ago after getting a complaint about such files missing +x perms on things like the configure script. check-in: b3d05a02f0 user: tangent tags: trunk
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 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
2019-08-15
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. Closed-Leaf check-in: bd10d4dde2 user: vermeulen.oscar tags: pi4-gpio-hack
2019-08-14
23:43
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

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
