'turns out that the doc's I have are for OptoTech drives, not Optimem.
Sorry - The doc's reminded me that the interface we dealt with most of the
time in the mid-'80's was a modified ESDI. If these are SCSI you're
probably OK, but if it looks like ESDI, be CERTAIN you get the matching
controller. The WORM drives I remember from Sperry, OptoTech, Cherokee,
etc, all used a modified ESDI interface. That meant you had to have the
matching controller with the matching firmware.

BTW ... Be careful what you get into with that R.J. Kulman guy, and don't
buy anything the functionality, condition, completeness, and normal price of
which is not precisely known to you. He's famous for selling things way
above retail when he can, and seldom has complete units.
