Hi Alain:

The connectors are for Q-Bus extension of VAX400-100. You will need
the following to
complete your task.

o Q-Bus extension cable set. (Two cables)
o Q-Bus Paddle cards to connect to other ends of cables.
o Q-Bus chassis of some kind. (For DR11 Q-Bus controller)

I don't have all these part numbers handy but if you want to proceed
along these
lines I can sell them to you. (Could get expensive: Like $800 - $1000)

You might be better served finding an old Q-Bus VAX in France. (Like
MVII,
VAXIII, VAX3600 or etc) We have that stuff here if I can help.

Best regards,

Len Whitwer
