Daves Old Computers - Commodore 128

The successor to the wildly successful Commodore 64, the Commodore 128 was both capable of running almost all Commodore 64 software, AND able to run CP/M software. This was accomplished by outfitting the machine with two CPU's, a 6502 compatible 6510, and a Z80.

I've listed this machine as "Fair" condition, due to the fact the it has suffered severe yellowing. It was used in a school, where it sat in direct sunlight for most of it's life. In all other respects, the machine is in excellent condition and works perfectly.

Later the same year (1985), Commodore released the Commodore 128D. Styled more like the IBM-PC this machine features a keyboard separate from the main unit which contains an internal 1571 disk drive. Additional video RAM gives this machine higher graphic capability than the orignal C128. Donated by Bill Mckinnon.
