The Telmac 1800[1] is an early microcomputer that was delivered in kit form.[2] It was introduced in 1977 by Telercas Oy,[3][4][5] the Finnish importer of RCA microchips. Most of the 2,000 kits manufactured over four years[5] were bought by electronics enthusiasts[1] in Finland, Sweden and Norway.
An expansion board, OSCOM, later became available, and included an alphanumeric video display, and up to 12 kB of memory. A 4 kB Tiny BASIC could be run on this configuration.[6]
The first-ever commercial video game to be developed in Finland, Chesmac, was developed by Raimo Suonio on a Telmac 1800 computer in 1979.[7]
The Telmac 1800 was followed by the Oscom Nano and the Telmac 2000.
