This was the only FDC board Delta made.

Delta FDC

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.

The (rudimentary) manual for this board can be obtained here.
