An early 80's computer, competitor to such machines as the Commodore 64, Apple //, and Sinclair Spectrum. the difference from them being that it was programmed in Forth instead of the usual (for that era) BASIC. It received little Software support, mostly from Forth hobbyist programmers. The company that built it, Jupiter Cantab, went out of business in 1984, and their machine died with them.
