I have an AVIV TFC-825 UNIBUS board, which I believe is a Pertec formatted TS11 interface. I also have an ABLE 10412-0 QBUS board, which I believe is some kind of UNIBUS->QBUS bridge. Naturally I've got absolutely no documentation on either. I've sent email to both AVIV and ABLE but haven't heard anything back. I'd like to use one or the other to help bootstrap a PDP-11/44 that I just got running last night. Plan 1 is to use the AVIV to interface to my existing DigiData 9-track drive. However, the DigiData uses 49-pin ribbon cables while the AVIV seems to want 59-pin cables. Plan 2 is to use the ABLE board to bridge the 11/44s UNIBUS to a QBUS backplane and then use a DigiData QBUS controller to connect to the tape drive. I've got all the hardware, cables, etc. to do this but I'm a little gunshy of just plowing ahead lest I end up letting the smoke out.
