|California Microlink Corporation 8" disk
drive controller for Atari Computers. This interface
board has 2 Atari SIO connectors on it for interfacing it to
standard Atari 400/800 computers (and later the Atari XL and
XE series computers.
Originally designed by Atari engineers Dave Shepperd
& Mike Albaugh as a way of being able to store larger
amounts of data with the Atari 800 computers. The design was
sold to a company called CMC where the final production
board design was made it was was sold through them. The interface is an
electronically elegant design, incorporating all the
necessary logic to allow Atari home computers the ability to
access large storage medium diskettes which could hold 10
times or more storage than a standard Atari 810 disk drive.
Sales of the interface board and other CMC
products did not sell well and eventually CMC would close in
1986 and the remaining inventory of boards & materials were
bought by Dave Shepperd. All items were acquired from
Dave Shepperd by the Atari Museum in 1998.
