High Quality Content by WIKIPEDIA articles! The Compukit UK101 microcomputer (1979) was a kit 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. The video output was black and white with 256 characters generated by a two kilobyte ROM. It had no bit-mapped graphics capability. The video was output through a UHF modulator, designed to connect to a TV set.
