The Alfa DiskFax was a communication device created by Alfa Systems of the United Kingdom. It was launched in 1990. The DiskFax was designed to allow the transfer of digital files over a conventional telephone line to a remote DiskFax machine. In operation users would insert an PC-compatible floppy disc into the unit, at which point the data would be transmitted automatically to a receiver, which would write an image of the data on a local floppy disc. There were two models, one equipped with 5¼-inch, and 3½-inch drives, and a second with an internal hard drive for storing incoming data.[1]
Encrypted versions of the DiskFax were sold to the military and intelligence markets.[2] The DiskFax was also used by Britain's Conservative Party during the 1992 general election.[3]
Alfa Systems was founded in 1985 by David Karlin, formerly of Sinclair Research.[4]
