CBM B256-80


The CBM 256-80 truely represents the top of the CBM-II line. The stylishly curved plastic case with detachable keyboard and built in monitor are a contrast to the rest of the CBM-II models, giving it the "High Profile" distinction.

The CBM 256-80 HP is the big brother to the CBM 128-80 HP and was known as the CBM 720 in Europe. Like the other CBM-II models, the 256-80 has a full-sized qwerty keyboard, 80 column display, Commodore BASIC 4.0, RS232-C and IEEE-488 ports, and the ability to attach an optional 8088 or Z-80 coprocessor board. The CBM 256-80 HP has an ample 256K of banked memory, and the particular model in this collection was also lucky enough to include the 8088 coprocessor board for running MS-DOS programs. MS-DOS compatility was considered an important feature at the time, as IBM was just beginning to envelope the business computing world.

The CBM-II High profile machines, which include the CBM 128-80, 256-80, 710, and 720, could all be purchased with built-in disk drives. These drives are said to be 8050 compatible mechanisms.
