This is a portable CP/M computer with an STD back plane for system cards and expansion. The C2150 model shown here came with an additional card to add LPT Parallel, 64KB of RAM, video output(unconfirmed), and an RTC.

The front of the computer only has three controls, main power, reset, and CRT intensity.

The Sony floppy drives in the machine are very early models and may need the shutter held open before putting them in the machine.

Repairs - Modifications

A note for working on this machine, the front faceplate uses Velcro strips to hold it to the internal cage. So you will hear a "tearing" sound when you slide the cage out. The keyboard faceplate is also held on this way, the keyboard cable is on a connector on both ends as well.
