Drive inventory

The 10+10 and 20+20 Bernoulli boxes did, indeed have a "nearly" SCSI interface
that was proprietary to Iomega, thanks, in part, to that DC37-cable
implementation they whipped up. It wasn't the same as what anyone else who
used that connector used, nor were the others, among which was Xebec with
their "Sider" drive, identical one to another.

I can come up with a host adapter, cable, and drivers, if you have something
to swap. I've got several of these old Bernoulli boxes, including quite a few
adapter boards, some of which actually work OK as 8-bit SCSI adapters.
Unfortunately, the media formatting software only works if you have their
adapter.
