Tangerine Computer Systems
Tangerine Computer Systems produced one of the first 6502 kit based machines. The company was run out of offices in Ely, in the United Kingdom. The Tangerine had a 3U form factor, not much memory, a video character generator and a simple latch for entering hex data from a keypad. The majority of the chips were not socketed which led to all sorts of hardware debugging issues. The manual came with a 1K listing of Conway's Game of Life. An optional expansion board could be built with UART, for keyboard, more memory and BASIC ROMs.
