Were both Memotech MTX and TEC-1 single-board kit computers?
Memotech MTX The Memotech MTX500, MTX512 and RS128 were a series of Zilog Z80A processor-based home computers released by Memotech in 1983 and 1984. They were technically similar to MSX computers, but were not compatible.
UTEC UTEC was a computer built at the University of Toronto (UofT) in the early 1950s. It was one of the first working computers in the world, although only built in a prototype form while awaiting funding for expansion into a full-scale version. This funding was eventually used to purchase a surplus Manchester Mark 1 from Ferranti in the UK instead, and UTEC quickly disappeared. The name was an acronym for "University of Toronto Electronic Computer".
