Digital Development Corporation Memory System.
UL 6200-128 Disk/Drum memory unit, mid-1960s, with blue-painted metal cover.
San Diego-Based Digital Development Corporation created a hybrid of drum memory and what would become the hard disk drive. The present unit utilizes an 11-inch disk and stacks the electronics into a drum format. Apparently a rare piece, this unit is serial number 2.
