That's a problem for all of us. Be happy that you're not dealing with
Unibus. Those SCSI controllers are even more rare and expensive...

Problem isn't building a SCSI controller, but the fact that you want it to
look like an MSCP controller from the computer perspective.

Having it talk raw SCSI isn't a good option. No boot programs exist, and
you'd also have problems booting it even if you did write you own boot
proms.
