This computer is what is the ZX-80 to the ZX-Spectrum, but for the Oric 1. Tangerine developped this computer before they became Oric and produced the Oric-1.
It was mainly sold in kit, without the complete keyboard shown in the photo, but 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.
Te 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 !
Hi, I am looking for a Microtan 65 in any condition. Bye, Achim

Mine travelled up to Applecross in 1984 when I was working at Kishorn in the Oil industry. I think it probably taught me what I needed to get that job! One highlight was writing a "word processor" for a Wang in 1983, learnt from the Microtan, that the whole department used as no one had seen a word processor before!
