I know this is not strictly Amiga but, I was going to get a C64 to midi with my Amiga. Sad news is my ebay win was a big looser. It has booted maybe twice, with some garbage screen and maybe twice with a normal looking blue start screen.No cursor blinking.
Well, question is, could it be fixed? Who can? Should not bother and just keep it for parts and find another one? If so, I hope to salvage the SID off this one...
Garbage screen? Check the 2364 ROMs. And, yes, it's fixable.
If you can't find any replacements, consider making your own 2764-to-2364 adapters (see
here)
I went through the exact same thing (and symptoms) while reviving an old C64 a few months ago.
