Most MicroVAX-I machines shipped in BA23s, but I believe they were
also available in BA123s. They are not picky; they just require a
standard 22-bit Q/CD backplane. I've run them in BA11-SA boxes before.

The cabinet for the microvax I is different that the BA123 and the BA23 that are
available for the later vaxes I believe. This model has a chassis which is
6"x28"x22", and a KD23 CPU (probably faulty). It has a maximum RAM
capability of 4MB. It definitely cannot run netbsd later than 1.61, maybe nothing before
that, but I haven't validated...
I figured that I had gone as far as I could go with the hardware anyway. If I can't
find a good priced replacement in the uv-II or uv-III/III+ line maybe I'll look for a
replacement CPU (if thats all that failed).
I do want to stick with the 5.2 license for the time being, perhaps I will play with my
7.3 hobbyist license when I get bored with it.

I have never seen a MicroVAX I, but according to this manual the
backplane is the same H9278-A that you would find in a BA23:
