Commodore 65 prototype sells for $7,625

Developed around 1991, the 3.54MHz Commodore 65 was designed to build on the C64's success and, like the Commodore 128, be generally compatible with its software.

The 8-bit C65 had improved graphics, a built-in 3.5-inch floppy drive, up to 8MB of RAM, and 128K ROM. It ran Commodore BASIC 10.0.
