Big "was", not "is". We shut the doors there in the Fall of 1993, IIRC.
I scooped up what I could, but we left the 8530 (and the TU-78, and
a pair of RK07s, and about 30 CiTOH VT100 clones, etc., etc.) behind.

I did get its Pro380, the 11/730, 11/750, 11/04, 11/24, 11/34s, 11/03,
11/23s, MicroVAXen, the 8300, the TU80, the raised floor (about 110 tiles)
and a bunch of other stuff (test equipment, printers, dozens of DEC
terminals, comms racks...) There just wasn't room for everything.

I don't remember any particular problems with reliability, but OTOH, it
was mostly a driver test bed for our VAXBI product - the NMI was
substantially different from a native VAXBI machine like the 8300...
turns out we were doing the "wrong thing" in the driver when we went
to stop the board (bad advice from a VMS device driver manual). The 8300
didn't care, but anything with an NMI curled up its toes and died hard.

The fix... commenting out one line of the driver. :-)
