[sgroup] S-760 SCSI troubles

I was given a S-760 ( with ctr/mouse ), PS Systems rackmount containing Syquest 44mg and a cd rom (without the cd tray insert). This system works great, except the cd rom is usless without the tray.   I want to expand the SCSI chain but can not. Even a Iomega 100meg zip between the S-760 and the Syquest locks up the sampler. Not to mention my attempts to add a computer.   -I've changed the SCSI ID # on the S-760 to all available #s, no luck. -Syquest ID 5 -started with really old computers, last being a dell optiplex gx240 (I'm looking for a mac)   Maybe someones kid can help me.   Bruce Riley, Chicago
