According to Zimmer's site, the following is true of the ROM in position U47
970018-12 2764 EPROM Waterloo A000-BFFF
I tried to read mine, came up all FFFFFFF's.
Chip works fine. Curious if I am missing something. Is this a 2764A? Anyone have a ROM they can read in their ePROM device to confirm my finding? I want to make a replacement ROM, and I was hoping to simply make a copy of a working one.
Nothing with Commodore is easy, but sheesh.
