===== History and Trivia =====

Telmac TMC-600 is the only microcomputer ever designed and manufactured in Finland. Only 600 units were produced, hence the model name. The computer casing was available in black and brown. The computer was designed by Timo Virtaneva and Hannu Peiponen. Two versions were released, the later allowing the connection of multiple peripherals simultaneously.

The TMC-700 expansion added Centronics interface with a custom connector, an RF modulator, and a real-time clock. 360KB 5.25" and 8" floppy disk drives could be connected using an external controller card. Other add-ons included RAM expansions, an I/O controller, an A/D converter, an RS-232C controller, a B/W 132-character display controller, and a parallel/serial slave computer. The TMC-600 was designed also for use in industrial process control applications, so BASIC ROMs with user-customized keywords were available on order.

The manufacturer, Telercas Oy, was an early Finnish distributor for RCA semiconductors. Telercas Oy was merged with the Finnish electronics retailer Yleiselektroniikka Oy in 1988.
