The MicroVAX 3800 and MicroVAX 3900 are very similar, the only distinction being the enclosure and accompanying disk drives: the 3800 was available in the BA213, and the 3900 in the H9644 cabinet. The MicroVAX 3900 includes an RA90. They both used the KA655 CPU.
The MicroVAX 3900 is the original model of VAX emulated by SIMH. (It now also emulates a VAX 780.) It can run 4.3 BSD, VMS 5.1-1 to 7.3, and NetBSD, and OpenVMS 7.3 under Debian on a Tinkerboard.
