Usage


MESS supports the emulation of a microtan with a "cassette" (cass) device. Cassette tapes must be in .wav format.

Also notice that a "snapshot" (dump) feature is available for .m65 files and that a "quickload" (quik) feature is available for .hex files.

Keyboard

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).

Original Keyboard:

History and Trivia


Tangerine developed this computer before they became Oric and produced the Oric-1. It was mainly sold in kit with a little hexadecimal keyboard.

The unextended Microtan 65 couldn't use Basic (Basic65) due to its RAM limitation (1kb), so only machine-code was usable.

The 1kb ROM contained TANBUG, a monitor which allowed to enter machine code programs. But with the unextended Microtan65, there was no way to save your work (not tape facility), so you had to re-type your program each time you switched-on the computer!
