I think SASI and SCSI are virtually identical for most purposes.
SCSI basically adds fancy things like syncronous transfer, arbitration,
more commands, etc., that you probably will not need.
I built a SCSI host interface for a custom Z80 system out of
latches and gates; it only took about 10 chips or so.
If your stuff is supposed to be connected to a PC,
a local surplus place has lots of host adapters for $15.
These were made by Ampex for a hard disk add-on system.
They have no documentation, but I have disassembled
the ROM code on them and written a device driver to
control a hard disk on my PC.
Halted Specialties in Sunnyvale (Call 408 555-1212 for the phone)
has the host adapters. If anyone out there has bought one
or could use such a thing, let me know and I will post the code
for my device driver.
