I couple of years ago I got a VS3100M30 with 2 RZ23 SCSI disks. They 
both seem to work fine in that VS, but I have NEVER gotten them to 
function with any other SCSI controller. Not that I have spent the 
intervening years hunting for a place to use it, but I know that I have 
tried a CQD-220/M for example and a couple Adaptec SCSI boards in a PC 
and a sound card SCSI once.

The RZ23 is about 100MB. Pretty small really, but I am curious if this 
is typical. Is it really that picky about the controller?
