Or maybe I should just run simh... I'm not
really a hardware guy anyway!
You could make one like DEC used to: Take an 8-slot backplane, and
fill in four of the slots with epoxy. You now have a 4 slot backplane.

I didn't know it was OK to use a hydraulic press for PC board installation,
I was always told that if it didn't fit then you needed a bigger hammer. 4
pound hammers are less likely cause less damage than hydraulic presses.

Is there a description somewhere of all of the BA11-?? variants? It
seems that there are many of them and they are of various sizes and
shapes. In fact, I think that the cabinet my 11/23-AH is mounted in is
a BA11 of some sort (a BA11-AH maybe?) but it is nowhere near as small
as this BA11-VA that you describe. I've found various lists of QBus
modules on the net but no list of the various boxes that DEC produced.
Can someone point me to one?
And, I'll repeat my question, does anyone have one of these small -11
QBus boxes they'd like to sell or trade? It seems that the BA23 might
be a good choice as well.
Thanks,
David
