The Viking QDT (disk/tape also available as tape or disk only) aren't 
the fastest boards out there (I think those are the CMD boards), but 
they're good rock solid boards.  With the most recent versions of 
firmware they should work good with a CD-ROM.  While I use mine in 
PDP-11's, I'm thinking about putting one in a MicroVAX III (I want to 
move off RA72's and RA73's).  I typically have Seagate 2GB 
Barracuda's, a Plextor 8x CD-ROM, and either a TZ30 or TLZ06 (4mm) 
attached.  I've also used a 2x DEC CD-ROM, and IBM 100Mb and 200MB 
SCSI drives in the past.
