VICE emulates the 6502 including the illegals which are valid opcodes (or nops) on the 65c02. But you could always modify the cpu emulation in VICE, or stick to the opcodes which are the same on 6502 and 65c02...

1664 Byte = copy time at least 1664 * 2 * 6 = 19968 Well, if the memory layout isn't important, you could always move the STA's around and only have each possible LDA#$ once, thus using (worst case) (256 * 2 + 1664 * 4) * 2 = 14336 cycles. There is after all no need to spend time setting the accumu...

I have an MPS-801 at home, simply because it was the very first printer I owned. Haven't used it in years. I remeber using it with GEOS, which was a pain (not GEOS, but the MPS-801) as it has some weirdo 69x69 DPI resolution (or something) compared to the standard 80x72 one...

Maybe you could contact Loriano Pagni who have designed and produced cases for custom boards before. Look here. (I'm getting a case for my 1541U from him.)

Maybe it's the emulator that's skipping frames? What computer are you using?

The builtin zip-extractor in Windows has to be the slowest implementation of the algorithm ever. I wouldn't be surprised if the VIC-20 could do it faster... Just install WinRAR (or similar).

Altering the colour RAM on the fly doesn't work. A LDA/STA pair needs 9 cycles for transferring a single byte. A horizontal line amounts to 71 cycles available to the CPU. LDA #imm + STA abs should be 2 + 4 = 6 cycles, and assuming the same color change is to be done for several chars, the amount o...
