The Compukit UK101 microcomputer (1979)[1] is a kit[2] clone of the Ohio Scientific Superboard II single-board computer, with a few enhancements for the UK market - notably replacing the 24×24 (add guardband kit to give 32×32) screen display with a more useful 48×16 layout working at UK video frequencies.[3][4][5] The video output is black and white with 256 semigraphic characters[6][7] generated by a two kilobyte ROM. It has no bit-mapped graphics capability. The video is output through a UHF modulator, designed to connect to a TV set.
