I am not exactly sure which ones you are referring to. The power
connectors are mfg by Molex, and I believe they are still available.
(perhaps not the exact same form factor, but something close)
Perhaps you are referring to a rare device, the Q-bus slot extender.
At its simplest, the slot extender is quad-sized module with a Q-bus
slot on one end and Q-bus fingers on the other, and a set of traces
that link the fingers to the slots. When inserted into the backplane,
it allows a Q-bus card to be mounted above the plane of the other
modules. This slot extender can be very useful if you're building or
debugging a Q-bus module, assuming the timing and signaling changes
caused by the extender don't preclude its use.
Unfortunately I have no idea what the part number is. I've only seen
one a few times, never used it.
This slot extender is not to be confused with the M9400-series and
M9401-series bus extender. The bus extender can allow two Q-bus
backplanes to be joined, such as the two connected BA23 boxes
configured in the so-called Q5 series MicroVAX configurations.
Here are some possible modules you may be referring to:
M9400-YE: Headers and 250-ohm terminators can be used with M9401 as a
M9400-YF: M9400-YA with boot sockets with no ROMs
M9400-YH: LDP/COMM boot & floppy boot with terminators
M9400-YJ DMA refresh bootstrap, cable connector, 250-ohm
M9400-YK: M9400-YH with no terminators
M9400-YL: M9400-YH with cable connectors
M9400-YM: Refresh with DECnet bootstrap
If you are referring to the blue connectors on these boards, they are
mfg by Berg. I don't recall the part numbers as it has been too long
ago. I believe they are still manufactured. A second source is T&B
(Thomas & Betts) or T&B Ansley.
Here is a picture of a M9400-YE:
Hope that helps

if you are looking for the green connectors shown on the third picture
I can send you 4 pieces gegen Postgebühr France-Germany.
They are manufactured by EDAC reference 346-036-520-201 and I got them
from Sayal in Toronto.
If somebody needs a complete backplane with 8 slots 70-19986-00
contact me !
Oh yes Peter, that's exactly what I'm looking for.
I've found in the meantime EDAC 346 Seriex connectors at mouser.com but they
are all to long (40, 54, 100 pins).
Do you have a paypal account? Or would you get the shipping costs with
a std. EU Bank Transfer?
Wat do you want for the backplane?
I've simply want to repair some old Cards, in the moment I have a
defective DEQNA here, so I need some kind of slot extender to get out of
the card cage to do some measurements...
Just a heads up!! I have seen comments in some of my mainenance docs
about certain cards that can not be run on an extender. Some of the
stuff in the 11/44 comes immediately to mind.

Lets see, I'll check this, it's better as not to try it at all.
My biggest Problem is that there are no schmatics available for the DEQNA,
most of the logic is in some binary programmable logic sequencers and PALs,
there is almost nothing repariable..
Oh, I understand...you wanted a card extender....Yes, those connectors
are made by EDAC.
I have a few extender cards that I use with my HP logic analyzer on my
unibus and qbus system...I'll look and
see if I can find the p/n.
