This FDC board used IO ports to read/write to floppy disks (as opposed to
DMA access used by some boards). It utilized the Western Digital 1795
FDC chip and a Western Digital WD2143 Phase Clock Seperator. The
board/Software could be jumpered for a wide range of 8" and 5" floppy disk
formats in single or double density. Various modifications were given
for different drives types including PerSci drives.
