Industrial Micro Systems -
The model 400 and 430 Floppy Disk
Controller boards were used in the IMS Series 8000 and 5000 Series systems
The IMS FDC boards used the NEC 765 FDC
controller chip rather than the WD 179x series. The boards could be configured
to work with 8" or 5" drives in single and double density. An on board 8257 DMA
controller provided for fast disk I/O. The board could control up to 4 drives.
The 400 series were hardware fixed to I/O ports 80H - 8FH. The
closely related 430 board could also be jumpered to I/O ports C0H - CFH.
The board could also use the S-100 vectored interrupt lines.
