Re: CBM prg Studio

A small error in the debugger:

Code: Select all

     LDX  #2
     STA $FFFF,X
This crashes the debugger (and the program suite) with an exception error. This is under V3.13.0

Re: SuperCPU for the Vic-20

Another update: The Vic-6560 emulation now seems to work as it should. I had to rewrite the clock logic completely as it was screwing up when screen map and character map was sharing the same space. Dual char height and column register now works as expected. Still have to implement left border adjus...

Re: 40 80 column cards

No and as a matter of fact, my Protecto 80 was destroyed while I was hospitalized and my stuff recovered. :cry: Oh no, thats too bad! This, I thought I already did. Didn't I post it on the Wiki ? I could only find the files for the Zero 18 board. In fact, the Data 20 files (in the wayback archive) ...

Re: 40 80 column cards

Imagine when teachers punished naughty school kids with having to rewrite the same sentence 200 times. It's not 'complicated'. It's long and tedious... That's what cloning the Protecto 80 represents. It uses only through-hole circuits and there's no copy protection per se. Everything about it is kn...

Re: SuperCPU for the Vic-20

After alot of debugging, the SD Card code has been improved with error correction. The card is now driven from the external clock so that it has a more stable frequency of 24.966MHz. Previous attempts at driving the SPI bus that fast did not work very well. Still, some read errors were seen once in ...

Re: Screen POKE - Help

With screen at 7680, color map is at 38400, so try

POKE7702,0:POKE38422,0

Should set the first character of the second line to @, then change the color from white to black.

Re: SuperCPU for the Vic-20

Well, I finally got some Ecliptek Oscillators at 16.384MHz. After some troubleshooting I got the VGA working again and its very stable compared to using the internal silicon oscillator. The rightmost edge is not oscillating anymore: IMG_0844.jpg The 65.5MHz clock is 0.7% higher which gives a mismatc...

I think he meant that many MOS6502s from China are in fact other types of 6502's.

WDC 6502 should have the STP and WAI opcodes...

Re: SuperCPU for the Vic-20

Small update: After some rigorous testing, I found that the internal silicon oscillator of the MachXO3 is too unstable to be useable. I tested the board at several temperatures, which showed that the internal counters would have to take temperature into account (which would be too complicated). Fort...
