iz8dwf | IZ8DWF gets mail #2! C64 PLA and how to quickly check a rebadged 6502. @iz8dwf | Uploaded September 2021 | Updated October 2024, 12 minutes ago.
Thanks to Marc for sending me a few spare chips! I've finally got an original "C64A" 82S100 so I can get the official fuse map. Plus, it's a 1982 chip
that's perfect for my Rev. A C64 PCB!
A quick look at the somewhat rare 24 pins 8 kBytes eprom MCM68766.
A few tests to determine what a "rebadged" or "remarked" 6502 from China can be.
