Compukit UK101

From Wikipedia, the free encyclopedia

The Compukit UK101 microcomputer (1979) was a kit clone of the Ohio Scientific Superboard single-board computer, with a few enhancements for the UK market - notably replacing the 24x30 screen display with a more useful 48x16 layout working at UK video frequencies.

It was powered by a 6502 microprocessor CPU running at 1 MHz, and was equipped with up to 8 kilobytes of RAM using 2114 static RAM chips of 1Kx4-bit. An additional memory-mapped 1K of RAM was used for the video display. It had the 8K Microsoft BASIC interpreter stored in ROM together with 2K of monitor ROM. The video output was black and white with 256 characters generated by a 2K ROM. It had no bit-mapped graphics capability.

The UK101 design was published in Practical Electronics, a popular hobbyists magazine at the time.

Kits of parts for building the machine were available from Comp Shop Ltd of Station Road, New Barnet (North London).

In common with other home computers of the time, software could be saved and loaded on standard cassette tapes. The UK101 uses the Kansas City standard tape format.
