UNIBUS extension card/cable sets

Somewhere I have the expansion box that went with this VAX. The thing is that I moved some items into a storage unit for the house move and haven't moved them back again. I suspect the expansion box was amongst them. When I get a circular tuit of a suitable type I will take a look at what is in there. The M9014 is just connectors. There are 3 40 pin Berg headers, one row of each appears to be ground (or at least they're all joined together and if they go somewhere other than ground I will be very surprised) That leaves 60 pins for the unibus signals. Of course power will not be carried. I would be very surprised. Unibus is normally terminated at the ends and not in the middle. I guess the 11/730 terminates the 'start', you put an M9302 in the 'end' I think I did read somewhere you could use a BC11A cable with the 11/730 (this does not surprise me), so that would not have extra termination. -tony
