Supra Corporation was best known as a manufacturer of modems for personal computers, but also produced a range of hardware for the Amiga and Atari ST, including hard drives, SCSI controllers, memory boards, and processor accelerators.

The company was founded by John Wiley and Alan Ackerman as Microbits Peripheral Products (MPP), a provider of interface products for Atari 8-bit computers.

The company was successful for some time, but a number of factors led to its bankruptcy around 1986, and its reformation as Supra, initially selling hard drives for the Atari ST.

Originally from Albany, Oregon, they later moved to Vancouver, Washington.

Their SupraFAXModem 14400 was sold at prices points about half that of the slower 9600 V.32 models of the same era, and its introduction led to a rapid downward spiral in modem pricing.
