Usually at MicroVAXen in those cute little enclosures, the QBus can be
connected to 2 50pin DSub connectors (those with 3 lines of pins, one male and
one female). So it is e.g. at the VAX 4000-105A. Do you have such connectors?

Hm. Has it any more connectors? Maybe SCSI or DSSI, which is included as
add-on-card on some newer models.

Correct. This is the problem on all the NVAX-machines i did the support for.
Currently, you can just boot off the network or QBus. Feel free to have a look
into the booter sources, if you find more time than i do ;)
