> @siz: Indeed, the major suspect now is the 6510 based CPU replacement with patched KERNAL. I'm just wondering if there's any other solution than replacing both the CPU and the KERNAL.
The 6510 CPU has a different built-in I/O port which is not compatible with the one in the 7501/8501. With KERNAL patches it's usable for stuff using standard KERNAL routines. But as soon as you want to have something with custom loaders (like disk based games and demos) it won't work. You HAVE to replace both your CPU and KERNAL.
