For programming the WD33C93 there is an Application Note from Western
Digital:

WD33C92 and WD33C93 SCSI Bus Interface Controller Starter Kit V1.0
Western Digital Corp. Applications Engineering, November 1986
written by John Spongr
(WD Document No. 79-000116)

There are also some Application Notes available on how to connect the
Device to Intel-type CPU's.

It was VERY difficult, to get these Notes from WD ....
