I recently "fixed" my C16. And by "fixed," I mean I tried to replace the 8501 with a 6510, only to discover that the replacement ROM chip was not working. Replacing with the original ROM and CPU brought it back. I tried multiple 6510s and all had been tested in multiple C64s. So I'm relatively sure that the replacement CPUs were not the problem.
In any case,I also have a CBM 4040 floppy drive that needed a similar part substitution, in this case it was the 6530 RRIOT which I ordered from Monotech, due to a single flash error that indicated either a zero page RAM fail related to the 6530 or a bad 6504. I ended up replacing both, however, the issue continued. This has me wondering if I ordered the right ROM version for my drive.
As such, I'm wondering if anyone has or can direct me to the correct files for these so that I might program a replacement? Assuming I can with the Promenade C1 I got for my C64.
