This electronic calculator was released by Sinclair Radionics in early 1978, along with the Sinclair President calculator. They were two of the last calculators produced by the company before they focused on home computers.

The calculator is slightly larger than its predecessors, intended for desktop use rather than being readily portable. The screen used is an eight digit vacuum fluorescent display and the system requires 2 AA batteries to power. The President Scientific had additional log and trig functions.
