Memotech Limited was a British computer company founded by Geoff Boyd and Robert Branton in Witney in Oxfordshire, England.
Norbit Elektronikk used their Super ToolBox system and was able to use 16-bits by adding two data blocks of 8 bits at the same time.
A contributing factor, beyond the poor commercial success of the MTX, was the substantial investment Memotech made in preparing the MTX512 for the Soviet deal.
As a result, Memotech required cash payments from the USSR prior to supplying the 64,000 computers.
Only a few thousand MSX computers were supplied to USSR schools and other educational institutions [6][7] before the deal went dead.
Boyd continued to market and support the MTX500, MTX512 and RS128 with the final MTX computer, the MTX512S2 being released late in 1986.
