And the MV3100m9{0,5,6} are identical to the
VAX4000m10{0,5,6}. The difference is that the MV models can't
use the QBus adapter (on the base
board) and have no DSSI (on an opton board?).
The mainboards are the same (i.e. a KA50 *is* a KA52 etc.)
and there is a console test that switches the identity
back and forth. So if you switch the identity you can use the
Qbus interface and the DSSI. Obviously you have to have a
Qbus extension cable and some way of connecting it - the easiest
way is a VAX 4000-1xx cab :-) I don't remember whether
DSSI needs an additional board which is part of the VAX 4000-1xx
cab or whether it too just works.
Sad that I have not the QBus cabling for my MV3100m95.
A 83
MHz NVAX (32
VUPs?) desktop VAX wirh QBus would be nice.
It would indeed. The VAX 4000-1xx range is something that
I only rarely got to play on. But there are plenty of
other Qbus boxes around.
