MESS currently supports the tmc2000 with a "cassette" (cass) device, supporting tapes in .wav format.

Also, a "quickload" (quik) feature is present for .bin files.


This system requires full keyboard emulation to work correctly. At startup, full keyboard emulation mode is enabled by default. Whilst in full keyboard emulation mode, some key associated functionality may be disabled (like the ESC key for EXIT). The keyboard emulation mode is toggled using the "Scroll Lock" key (by default).

RAM options

Different RAM configurations are possible for the tmc2000 in MESS. You can switch between them, changing the -ramsize parameter. At command line, you simply have to add ''-ramsize ram_value'', where //ram_value// can assume one of the following values

16k (default)

History and Trivia

Telmac 1800 was a simple CDP1802 system introduced here in Finland around 1977. It was designed by Osmo Kainulainen, who built his own computer using a RCA CDP1801, that he already knew from his job. The design was published in a magazine and more or less started the hobby computing age in Finland by soon turning into Telmac 1800 kit, which used CDP1802. It was quite similar to COSMAC VIP, but not exactly the same.

Telmac 1800 was manufactured by Telercas Oy, which also was a distributor of RCA components in Finland. It was delivered as a kit and gained quite a big success.

The Telmac 1800 was followed by Oscom Nano and Telmac 2000, which had PAL version video chip (1864) with color also supported and more RAM, board could hold 16k bytes.

Finally, the more professional TMC-600 followed.
