The Soviet government was also evaluating computer systems from other home computer manufacturers. Memotech was relying on the British government for funding the project, but ultimately, they only received about £1m and did not receive the full funding required. As a result, Memotech required cash payments from the USSR prior to supplying the 64,000 computers. The Soviets decided against this cash deal and instead agreed to acquire

Since Memotech lost the deal to the USSR, and they had invested all their money in the project, money that was borrowed from the banks, plus the £1m funding from the UK government, Memotech went bankrupt. Some of the Memotech inventions still lived on, as several employees took some of Memotech's new video editing systems for televisions back to the USA. As a result of Memotech's bankruptcy, the UK government stopped funding to all computer manufacturers in the UK at that time, including Sinclair, Acorn

Successors
Robert Branton had left the company in 1985 as the financial situation deteriorated and when Memotech Limited folded, Geoff Boyd acquired the assets of the old company and re-launched the company as Memotech Computers Limited in February 1986. Boyd continued to market and support the MTX500, MTX512 and RS128 with the final MTX computer, the MTX512S2 being released late in 1986.
