IIRC, it will run up to either v7.2 or 7.3, at least I know I had v7.2 on a MicroVAX III (well, technically I still do, if it will boot).

I have booted both V7.3 and V5.5-2 off a 4GB SD with SCSI2SD V4.6 on a MicroVax II with 16 Mb. Note that DEQNA will not work (at all) on either version. You’ll need a DELQA.
You should be able to build a system with an emulator and then copy the binary to an SD card. i’ve taken images both ways without problems. Alternately if you get a DELQA, you can netboot off of another Vaxen and build an bootable disk that way.
