Nanodata was a Buffalo, New York company that was formed in 1971 and seems to have sold its first products in 1973. They filed for bankruptcy in 1982, though they may have carried on business for a couple of years after that.
They seem to have manufactured two computers, the QM-1 (possibly also known as the "MultiMicroMachine") and the QMX. According to a 1978 brochure The QM-1 could emulate many other computers and peripherals: "A 'typical' customer configuration sells for $280K and includes emulators of the PDP-11, Data General Nova, IBM 360, etc." The only documentation I've seen related to any of this is this Bitsavers archive.
What's the history of this company? How well did their computers sell, and who used them? Has anybody (outside of the company itself) provided reviews of their systems describing their good and bad points, and how they compared to other systems of the day?
