Yes. I still have it, but the drive has been dead since before I got
in 20 years ago.

I don't know the exact model, but if you sent me pictures, I'd
probably recognize it. I can't easily get to mine or I'd take
pictures for you.
We bought it at Software Results sometime before 1986, IIRC. It was
many thousands of dollars and pretty much never did what it was meant
to do. I ended up with it because nobody could make it work and I
think we were kinda left out in the cold for vendor support. ISTR
getting something going with the floppy controller, but we had no docs
on the DQ614 at the time (I think someone on the list sent me
something a while back) so I never saw this thing do much more than
It seems to be a nice (large) desktop package. At the time I saw
this, my small DEC experience was PDP-8s and the smaller PDP-11s like
the 11/34 and 11/24 (the /24 was the accounting machine, running RSTS
on 4 RL02s for OS and data). The Dataram box was, to me, a good-sized
"personal PDP-11" packaging. The BA23, when it came out, was clearly
intended for single-user or very small (2-4) groups, but prior to
that, all I'd ever seen was racked.
