The CBM 128-80 sits at 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 128-80 HP is the little brother to the CBM 256-80 HP and was known as the CBM 710 in Europe. Like the other CBM-II models, the 128-80 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 128-80 HP has 128K 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. This model also included a third party IEC board for using Commodore serial drives, such as the 1541
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.
