I started reimplementing Multicomp6809 (Grant Searle's Multicomp FPGA project, see: http://searle.hostei.com/grant/Multicomp/ ) You can start it with: /DragonPy$ ./DragonPy_CLI.py --machine Multicomp6809 run or with the shell script: /DragonPy$ ./run_Multicomp6809.sh Looks currently like this: http:...

I modify the test script a little bit and count to 500: 10 COUNT=500 20 CLS 30 TIMER=0 40 FOR I=0 TO COUNT 50 PRINT @0,"COUNTER=";I;"- TIMER=";TIMER 60 NEXT I run this on a real Dragon 64 and get: COUNTER=500 - TIMER=761 I start it multiple times and get: 760, 761, 760, 761, 761, 761, 761, 761, 761,...

I found the IRQ trace part of XRoar: https://gist.github.com/jedie/4400c4c086c3b2d84592 (on gist, because of linebreaks here) So, the IRQ routine reads PIA from $ff03 and $ff02: 9d3d| b6ff03 LDA $ff03 cc=98 a=b5 b=01 dp=00 x=00b4 y=b39b u=82ec s=7f1e| E..IN... 9d43| b6ff02 LDA $ff02 cc=94 a=00 b=01 ...

I add a "config" menu (Currently the values are not load/save)... Now you can limit the speed: http://www.jensdiemer.de/static/jensdiemer.de/screenshots/20140913_DragonPy_PyPy.png I also add a IRQ callback function. It's not really "realtime" possible, because the target cycles/sec does varies very ...

Good question... I will check this. Maybe my simple PIA implementation is wrong here... Thanks for the suggestions...

I have update the CoCo code and add a logging routine for the TIMER read/write: https://github.com/jedie/DragonPy/compare/8c02cfc...804f7b4 Coco logging looks like this: ... MainProcess/MainThread $a7d5 *** IRQ, set PC to $010c E....... MainProcess/MainThread 8955| read byte $00 TIMER value from: $0...

There is a Wiki page about Dragon Plus: http://archive.worldofdragon.org/index. ... ragon_Plus

Maybe, place this pictures there and link the page also here: http://archive.worldofdragon.org/index. ... e_Pictures ?

I have IMHO now a better implementation via callback, with: https://github.com/jedie/DragonPy/commi ... 1d5b476194

I see that IRQ is called and PC goes to $010c but the TIMER value doesn't increase as it should

Wow. All self written? Are all pure BASIC ?
Are the code open source? Which licence?

btw. the MC-10 emulator from your homepage has some very interesting debug features
