Microvax I is apparently BA23

Good point. Since he said MicroVAX II, I assumed BA123, but it could
be in
a BA23.
I've never seen a -I in a BA123, only BA23s. That may just be
incidental, though.
I don't have any yet, and they're packed away. I will get them out at
some point and do a nice photo shoot. They really are nice little
boxes, and very different from the final production BA123. They are
built around a BA23 power supply and backplane (so only eight slots as
compared to the BA123's twelve). They only have four drive bays,
mounted horizontally in a vertical column on the right, with no
vertically-mounted left bay like that of the production BA123. They are
much smaller and lighter than a production BA123, but they still have
casters.
I have the wood tops for both of mine, but I am missing one side
cover, which is very sad. I'll hire a machinist to make me a new one
when I can afford to. Some of the sheet metal parts still sport some
blue layout dye and scribe marks!

If nothing else the powersupplies, and if it has them,
the side panels
should be saved. It has been my experience that the side panels are
harder
to get than the chassis itself.
What chassis are you talking about, BA123? I don't think Joe
mentioned what chassis his -II is in. I am
short a BA23 power supply. I have two hand-built BA123
prototypes, called "woody boxes" because of their gorgeous wooden
lids, that use BA23 power supplies...one of them has a dead PS. (yes
I checked that sentence for typos...BA23/BA123 above is correct :))
Very cool sounding! Pictures?
