I have an S100 amchine called a CASU Super C. It contains a Cromemco CPU 
board, some other stnadard 64K RAM bvoard, a Micromation Doubler disk 
controller and CASU-designed boot ROM and seiral interface boards.

The disk drive (a Persci) is in a separate box. The 50 wire interface 
cable is split down the middle adn connected to a pair of DB25s...
