odd sounding box. The BA23 is a

The backplane is fixed in a main chassin and has a door over it and dress
covers. Sounds like a either a bs23 or BA213 skunk box. Most ba23s only
have one hard drive and either RX50 or TK50/70 tape.
This one is in a plastic case mounted on a pedestal..the cases outside
dimensions are: 6"W x 28-1/4" L x 24" H. The dimensions of the internal
chasis alone are approximately: 5"W x 24" L x 17-1/2" H. It certainly
doesn't
sound wide enough to be a BA123, which threw me off at first when Tim
suggested that's what it was. It doesn't seem to match the dimensions of the
BA23 though either, especially since it has two slide-mounted hard disks in
it, though it lacks a tape drive or any other type of removable media.
FYI the BA23 (Ihave one) slides into a plastic pedestal
case from the back.
or the metal box can have rack mount ears.
This one also alows the whole chasis to slide in and out of the pedestal
case...and it looks like it'd allow it to do it just as easily from the front
as it would the rear.
The 6x6 card? got me. A KA630a is quad width double
height (8.5x11).
Well my guaging of dimensions by eye leaves much to be desired..which is
why I took a seamstress tape to the case for the above dimensions!
If the OS is ultrix yes, VMS no. If the case is BA23
drve ready switches
should be off before turning on and off before turning off. I'd say don't
power it till you have a terminal anyhow as VAXen look for a console
terminal or they don't finish power diags or boot! It also queries the
terminal for what It is, the altos unless a vt100 clone will nto give the
right response (no biggie but there is some console editing that will not
happen then).
I'll keep an eye out for a VT-100 or such then....it doesnt look likely
I'll find a keyboard for the Altos anyhow. I think I've seen VT-100's for
about $50 on the newsgroups.

If it uses the answerback facility to do the query, you can probably get
by with any number of solutions. At least a couple of terminals I have
are able to set this string to match what a true vt100 would produce.
Also, don't discount the power of an old PC, or even a new PC running
e.g. Linux to communicate in the desired way.

If you're talking about the Altos III terminals (minus their
keyboards), I wouldn't give up just yet. IIRC, they used WYSE
terminals with (slightly) customized roms. If the keyboard plug is
round (kinda like a DIN plug, but with lots more pins) then a WY-50
keyboard should work.
If it is a modular phone plug, then it would be a WY-30 keyboard.
All bets are off if the terminal has a heavy, metal cabinet-- it's
probly a Wy-100, and keyboards for those are rather scarce.

Jeff,
Yes, I'm still referring to the Altos III, and yes it does have a DIN plug
with I believe 10 connectors. Thanks for the info!
