I resued a complete system of these not too long ago. They are from a CD 
Force network CD server, usually used in hospitals after they have moved 
archived records over to CD's. The server itself is a Pentium 233mmx 
socket 7 board in a 4u or 6u rackmount case. It has two dual channel LSI 
scsi controllers in it as well as an IDE boot disk. When the thing boots 
up it caches the cdrom data to those scsi disks so that it's faster 
access across the network. It doesn't really do any kind of array, more 
like a JBOD of CD's. I have the server side as well as three of the CD 
shelves. I haven't really had a chance to play with the original 
software, but I do have the original IDE boot disk sitting somewhere 
here since I didn't know if I'd ever need it. I may be able to take a 
disk image of the original boot disk if you need it, but I don't know if 
it's password protected, or even what OS it is as I wasn't kidding when 
I said that I've never played with it. Are you coming to Dayton for the 
Hamvention? If so, let me know and maybe we can work something out.
