Konan SMC-200 -- Hard Disk Controller Board
This was essentially Konan's SMC-100 dual board set compressed into a
single S-100 board.
The boards were used for fixed and removable media disk drives with storage
module (SMD) interfaces. It could control up to 2 drives per board set
ranging from 4 to 1200 MB, including most Winchester type drives.
Typical hard disks were those of Kennedy, Control Data, Fujitsu, Calcomp
Memorex and Ampex. Data transfer was fast (6-10 MHZ rates) with full
on-board sector buffering and DMA transfer. The controller was format
compatible with it's predecessor the SMC-100. The board appeared to the
CPU as six I/O ports (Drive select, Commands, sector address, sector buffer and
status). There was a common "bus cable" to both drives and a two
smaller cables, one to each drive.
