Kevin,

Thanks for the SCSI dope.

I called a supplier the other day to get some prices and info. He told me (in a
very knowing way) that the controller board WAS needed with a SCSI drive and
that the ST01 controller was *both* a host AND a controller (just like the MFN
controllers...). Guess that is why he is still selling IBM-type stuff .

Now I'll have to decide what size of HD I'll be needing. The fellow I talked to
offered a 110meg drive for 900+ $$. That's too much for sure--plus, then a tape
backup would be essential. Can you imagine backing up that much data onto
floppies! With prices as they are probably something around 30meg seems to be
reasonable.

So the cable acts like a bus and the devices have select pins (I guess like
floppies do right now). Is it possible to connect more than 8 devices to a
system? (Not that I'll be able to afford that many, but...).

Am I right in assuming that in order to hook up a "normal" disk drive to the
SCSI "bus" one would need a SCSI controller card for the drive? I guess that
the select would be on the controller, not the drive.

Okay, this is starting to make sense. Thanks.
