An impressive system for the time, in both size and capability. 64 KB of RAM and a full height Shugart 8 inch disk drive (capable of storing a whopping 500 KB) rounded out this 4 MHz Z80A microprocessor machine. The unit here also came with extra drives and even the printer. Capable of running CP/M, this machine found many uses with many different types of programs. The model is often forgotten about given the popularity of some of the other models, and the initial high price point ($3495 US). The machine is capable of 80x24 text but no pixel addressable graphics (only graphic characters to simulate).

This computer also ran Xenix - a version of Unix. It could serve several dumb terminals. As you say . . a very impressive computer in its day.
