The Commodore 65 (also known as the C64DX) was a prototype computer created by Fred Bowen and others at Commodore Business Machines in 1990-1991. The project was cancelled by CEO Irving Gould .
The C65 was an improved version of the Commodore 64, and it was meant to be backwards-compatible with the older computer, while still providing a number of advanced features close to that of the Amiga computer. When the company was liquidated in 1994, a number of prototypes were sold on the open market, and thus a few people actually own a Commodore 65. The guesses of the actual number of machines found on the open market range from 50 to 2000 pieces. As the C65 project were cancelled, the final 8-bit offering from CBM remained the triple-mode, 2MHz max., 128KB (expandable), C64-compatible Commodore 128 of 1985.
