SPDC PC-Compatible Floppy Disk Controller

The SPDC is a floppy disk controller for STEbus PC-compatible systems. Controlling up to four drives, the SPDC can be used with 5.25" or 3.5" drives (40 or 80 track double-sided double density). An on-board custom IC interfaces with the industry standard Intel 8272 or NEC µ765 floppy disk controller chip, to provide complete PC-compatibility, when used with other STEbus PC boards. With no links on-board for set up, the SPDC is simple to install and use.
