102b034 builds yaYUL exe 15 June 2020, 01:53:45 UTC
a38a94f Lots of changes for stuff I think (thought?) I had figured out about parity checks for the PRS instruction. It has gotten me farther along, but opened up a series of new questions that cast some doubts. 13 June 2020, 22:48:27 UTC
df18e4b Tab widths were messed up. Also, the RESET MACHINE pushbutton now changes the typewriter cartridge color to black. 10 June 2020, 20:25:45 UTC
4515df3 Corrected, I think, some carriage-return handling for the PTC printer. Added a very slight change to the background color for printed characters, so that it's possible to discern blank spaces at the ends of lines on the printer. Implemented the red cartridge for the typewriter peripheral. 10 June 2020, 20:11:40 UTC
346960f Of the 8 test routines in the PTC ADAPT Self-Test program, all except ROUTINE 4 seem to run without error ... at least, without the PROG ERR light turning on on the panel. That's just a preliminary assessment. ROUTINE 4 partially works, but doesn't make it all the way to the end. 10 June 2020, 19:13:22 UTC
b63c680 More fixes, facilitating the PTC self-test. Everything today was related to the typewriter peripheral, for which there was a lot of progress, but still not complete. (Stuck now at L27P1.) 09 June 2020, 00:14:59 UTC
51a0b6f Continued working through bugs discovered through the self-test. 08 June 2020, 02:38:04 UTC
0347366 Interrupts now implemented in yaLVDC; lots of changes to CIO instructions and PIO instructions, related to interrupts and discrete inputs and outputs. 06 June 2020, 23:09:20 UTC
9cfc7d5 Fixed several bugs in the LVDC/PTC CPU emulation that I found while running test procedures from the PTC ADAPT Self-Test Program. Many more to go! Also, improved the plotter and typewriter emulations slightly. 05 June 2020, 22:53:16 UTC
0a54533 Finished implementing the PTC plotter peripheral. It seems to work in so far as the test procedure says it ought to. 04 June 2020, 20:11:27 UTC
42bcdcd Yet again, made further corrections to how I think outputting data to the PTC printer is supposed to work. I think I finally have it correct now. Also, implemented the PTC typewriter. I don't see any way for the CPU to get keystrokes from it --- nor do I see that the PAST program tries to do so --- but perhaps some way will present itself later. 03 June 2020, 19:48:16 UTC
61443dd Added scaffolding for a gdb JUMP command in the yaLVDC's native debugger, but it doesn't do anything as of yet. 02 June 2020, 23:08:27 UTC
91f8582 I believe that my original interpretation of "octal mode" vs "BCD mode" in the PTC printer (i.e., of instructions CIO 164 and 170, as well as of CIO 160) was incorrect, and I've changed it according to my new understanding ... which is still incomplete and probably wrong in some respects. 02 June 2020, 22:25:39 UTC
f49dd17 Detached the printer peripheral from the emulated PTC panel, making it a separate window with better geometry and font than before, as well as now autoscrolling to keep the most-recently-printed line in view. Also added a similar typewriter window and a plotter window, though those don't yet actually do anything. 01 June 2020, 20:15:14 UTC
4860011 Simple printer-peripheral implementation for PTC. It sort of works, in a preliminary kind of way, but needs more work. 01 June 2020, 15:33:16 UTC
ba1eaf9 Added parts of Figure 7-9, but I no longer believe that the test-software version we have matches the one needed for the tests of Figures 7-8 through 7-10; this needs more research/thought. In looking at 7-11, I've fixed my implementation of indicators P1 through P40 on the PD, as well as the LAMP TEST for the PD (which was failing for indicator lamps that changed underlying states during the LAMP TEST). 31 May 2020, 14:43:18 UTC
680e071 Implemented the ACC display on the PTC panel. I don't know if it's right or not, since there are 58 bits instead of 26, but perhaps time will tell. Also, I was wrong in the note for my last commit: The DATA area (and ACCUMULATOR) are shown in their states _prior_ to executing the instruction, which makes more sense, given that ACC and DATA can show the before vs after states of STO and CLA instructions. 26 May 2020, 23:24:32 UTC
5ba3475 I think the ADDRESS COMPARE INS is completely implemented now, though I don't understand for STO instructions whether the DATA area is supposed to display the contents of the destination before or after the instruction is executed. I chosen _after_. I'm sure it will become apparent soon. By completely implemented, I mean that all 5 settings of MODE CONTROL seem to work, as does the ADVANCE button. 26 May 2020, 22:51:00 UTC
3b73342 Actually have some primitive watchpoint action going on in the PTC emulation now, in which you can watch the program execute and see a variable associated with an instruction address updating in real time on the panel. Still a long way to go, but it's a milestone. 26 May 2020, 20:14:33 UTC
0c5724a Improved to the point where I'm willing to say that the PTC test procedure from figure 7-7 "works", though in fact step 5.180 still fails and there are probably still other related problems I haven't detected yet. 24 May 2020, 20:18:37 UTC
6c799db More incremental improvements to PTC emulation, but mainly related to trying to work through the "Memory Loader Manual Checks" test procedure. A new file (LibreOffice spreadsheet) has been added that's basically a cut-and-paste of this test procedure, but with some typos corrected and with my notes added about differences when running the test in emulation. That's still not complete, but it's pretty substantial. 22 May 2020, 23:15:09 UTC
6f41b61 More improvements to PTC emulation. 20 May 2020, 22:33:57 UTC
bfbd33f More progress on PTC emulation. I seem to still be stuck on what ADDRESS COMPTR does, though; I keep thinking I have figured it out, but the test procedures still fail (Figure 7-7 sheet 3, 5.23). 20 May 2020, 18:48:59 UTC
d29bc1b Minor tweak. 19 May 2020, 23:07:31 UTC
f4148cf Lots of progress on the PTC panel emulation. 19 May 2020, 19:33:07 UTC
f0d8929 Some incremental updates to yaLVDC/yaPTC interactions. 18 May 2020, 14:31:08 UTC
27c3b27 Oops! Introduced a couple of unexpected compile-time errors in yaLVDC. 17 May 2020, 22:01:43 UTC
3cf7a47 Somehow the most-recent commits got bollixed, and there were conflicts for some reason. Hopefully this brings it back up to date. 17 May 2020, 21:57:55 UTC
aee3b68 Filled in a lot more of yaPTC's UI ... in fact, perhaps all of it, since I realize that I have filled in stuff (like the MBR) that probably can't emulated (at the level of detail of yaLVDC), so I may have to go back and remove some of it later. Not that much of it still actually does anything yet. 15 May 2020, 20:37:48 UTC
33e178a More additions to the PTC emulation user interface. 14 May 2020, 22:59:59 UTC
4fcfdd0 More work on the user interface for the PTC front-panel emulation. 14 May 2020, 21:11:05 UTC
f8a3204 Some prettifying for yaLVDC debugger LIST and DISASSEMBLE commands; this involves a change to the .src files produced by the yaASM.py assembler. Also, yaLVDC (and yaOBC/yaASM) build automatically when the Virtual AGC project is built from source. 13 May 2020, 18:47:19 UTC
5382684 Corrected source locations for certain address ranges of PIO instruction. 13 May 2020, 16:54:04 UTC
b1e1c91 Additional incremental fixes and extensions of the PTC emulation. 12 May 2020, 21:32:14 UTC
350660d I've added some placeholders for a C.E. Panel and Memory Load and Data Display Panel for yaPTC.py ... though unfortunately the minimalist instructions the PAGE tool gives explaining how very easy it is to have all these panels at once don't seem to do anything for me yet. 12 May 2020, 00:12:48 UTC
18d7a61 Continue incremental improvements to yaLVDC and yaPTC.py. 11 May 2020, 21:26:05 UTC
b32c97e Just a caution save, as I'm about to do some stuff I might want to undo. 11 May 2020, 15:50:09 UTC
b494620 Made some additional tweaks that _may_ make it work adequately at --divisor=2. On the other hand, as more elements are added to the GUI, it will likely slow down somewhat, so I'm not sure I can make any firm inferences about what values of --divisor are likely to work on an ongoing basis. Still, every little improvement helps. 10 May 2020, 23:19:41 UTC
debac68 Okay ... I found a configuration which (on my 3.2GHz hex-core i7) seem to allow yaPTC.py to keep up with yaLVDC --divisor=3. It can actually sort of keep up at --divisor=1, but some graphical operations seem to be queued up and may lag real time under some circumstances. At any rate, I'm hoping it will be good enough for my debugging purposes right now. 10 May 2020, 22:52:56 UTC
ec82602 It turns out that the yaPTC.py peripheral is far too slow to keep up with the yaLVDC CPU emulator ... it keeps receiving messages from yaLVDC that have been buffered by the operating system long after the CPU emulation is paused. I've added a command-line option to yaLVDC (--divisor) that can be used to slow down the CPU clock, but even at a factor of 10 it's still too slow. Well, I'll keep experimenting, since I don't want to have to reimplement yaPTC on a more-difficult platform if I don't have to. 10 May 2020, 20:25:10 UTC
17c5393 Fixed how the STO instruction saved return addresses (776, 777). The emulation no longer obviously fails (in the sense of landing on empty or corrupted memory ... but it's still early days yet, so give it time! 10 May 2020, 18:19:52 UTC
df487e7 Finished adding the DISASSEMBLE command to the LVDC debugger. It's awesome. Probably a few bugs I haven't noticed yet. 10 May 2020, 16:49:06 UTC
9e8c25d Realized that LVDC/PTC self-modifying code was thwarting some of the emulation and debugger functionality, particularly checks that I had added to make sure code came only from places initially designated as code memory. Moreover, given that modified code no longer matched the source lines, I've added a number of hooks (and actual code) related to warning about that situation and providing a dynamic disassembly when detected. (It's not just a meaningless flourish; it's about having enough debugging horsepower to track down bugs I'm actually seeing.) 09 May 2020, 21:12:34 UTC
a49070d Added some backtrace capability to the LVDC/PTC CPU emulation. More LVDC/PTC-to-peripheral protocol fixes, and more work on the peripheral emulation for the PTC. It's working better now, but there's a long way to go before it's truly usable. I've found a way to crash the PAST program (or at least to jump someplace where no man has gone before), so presumably the CPU emulation has still got some bugs in it. The backtrace is hopefully going to be helpful in tracking that down. 09 May 2020, 15:57:00 UTC
2ffa3d4 Some protocol fixes. A lot of initial work on the GUI portion of yaPTC.py. 09 May 2020, 00:34:30 UTC
fa6013c Fixed various things wrong with the "virtual wire" networking protocol and code. Added a crude PTC client peripheral written in Python. It does very little at the moment, but I'm going to flesh it out a lot. 07 May 2020, 20:45:23 UTC
102df44 Outputting on virtual wires now works a little better. 07 May 2020, 00:23:51 UTC
a9fdc68 Simplified. Made some fixes to NEXT and RUN. Added part of the "virtual wire" interface for hooking peripherals to the LVDC/PTC emulator, though the portion I did add doesn't seem to be working entirely correctly yet. 06 May 2020, 23:59:20 UTC
e2e1b21 Added various features to the debugger: eXamine memory, Next (as opposed to Step), Run. I think the debugger is in good enough shape now that I can resume implementing emulating, particularly PIO, CIO, and interrupts. 06 May 2020, 00:58:24 UTC
10515bb A lot of fleshing out and cleanup of the gdb-type debugger code in the LVDC/PTC CPU emulator. 04 May 2020, 21:26:50 UTC
180951b Partial implementation of LVDC/PTC breakpoints. 03 May 2020, 23:58:21 UTC
834a76a More progress on LVDC/PTC emulator, mainly on the debugger interface. 03 May 2020, 20:57:59 UTC
