The MicroVAX 3900 is rackmount only if you carefully remove the
skins. It includes an RA8x (maybe even RA9x) only if it comes
in an H9xxx cab (forget the exact number). The usual MicroVAX
3900 came in a BA213 (skunk box). The MicroVAX 3800 came in the
slightly smaller and slightly less heavy BA215.
You can find all sorts of info by heading over to Manx:
http://vt100.net/manx
and looking for BA213, BA215, KA650, KA655, MicroVAX 3800
and MicroVAX 3900.
If that isn't enough reading, you can look here:

for a BA213 and here:

You should be able to find plenty more with google.
Basically the 3200/35003600 use a KA650 and the 3800/3900
use the slightly faster KA655 processor. Almost everything
is interchangeable between the various versions.

Can anyone point me to info on the MicroVax 3800?
I may be
MicroVax 3800 is the same as MicroVax 3900 except for the
fact that MicroVax 3900 is rack mounted with RA9X disk. I have
a MicroVax 3900
bare box without the rack and disk at
http://www.wintersweet.com/computermuseum/VAX3900.html
A MicroVax 3800 is about the size of my 3900, weights around
100LBs,
has KA655 cpu, MS650 memory, KDA50 disk controller and TQK70
tape controller.
