DRC called this board the "Light Speed 100". It acted as a very
fast CPM disk with a capacity of 256K. It utilized the Intel 8203-1 Dynamic
RAM refresh controller and so was very reliable. It was also IEEE-696
compatible. All operations went through 4 constitutive I/O ports which was
switch configurable. The board came with some basic software to get it going
under CPM. Up to 8 boards could be configured in a S-100 system.
