PSI Comp 80

It was sold in the form of a kit of parts for a cased single-board home computer system.

In 1979, the British magazine Wireless World published the technical details for a "Scientific Computer".

Ahead of its time, it incorporated a number crunching coprocessor and a novel language embedded in EPROM called Basic Using Reverse Polish - BURP.

It was based upon a backplane and plug-in cards and modules and featuring a Hitachi HD64180 processor, up to 512 kbytes of RAM and a high-resolution colour graphics system.
