They are somewhat rare - I've seen three in my life, one was mine that
vanished when the business it was at was abruptly sold (it was out
on loan) :-(

Other than the size, it's nothing remarkable - an 11/730 CPU in a
box slightly bigger than a BA123. The RC25 has been hashed to death
here, but for its day, for 52MB of storage on a VAX, it was somewhat
compact.

It's a .6 VUPS machine that may or may not be able to take the full
5MB that the 11/730-Z backplane should (power and heat and what not).
I have seen one boot VMS 5.0, but there wasn't any elbow room.

I'm somewhat interested, but only because I don't have a Unibus VAX
up and running right now (I never got that DWBUA from Gunther to pass
self-tests in my 8200 - not sure if it's my UET board, the cables,
or the DWBUA itself).

They are no slower than an 11/730, and quite a bit more portable. It's
trivial to speed up the boot process to under 5 minutes, if you re-order
the files on the tape.

P.S. - speaking of tape, if the console TU-58 has gooey rollers, that
*will* keep it from booting. Unlike the 11/750, the 11/725 and the
11/730 *need* the console TU-58 to come up from a cold start.
