That's the BA123, they're my favorite DEC Q-Bus Chassis! Lots of room for
expansion, and easy to get at stuff. Though as I learned a week and a half
ago when I got the side panel I was missing the side panels make a good
puzzle :^)
The system probably had a TK50 at one point in that empty bay you mentioned.

Well, the RD50-52 and RD31/32 are really to small to be of use, thankfully
the RD54 seems to be a fairly good drive. I personally believe that the
best answer is to get a 3rd party ESDI controller or get really lucky and
get a SCSI controller (you don't want to know what they cost).
BTW, I liked your comments about OpenVMS and NetBSD. I'm a firm believer
of running VMS on these systems (though I've got to admit I'm thinking of
installing Ultrix).
