Hi, the UNIBUS FAQ sais that the grant cards G727A is a dual-height card with NPG grant. But from the cards I have I see the G727A is a single height card with only bus grant, not NPG, and it is a knucklebuster. The one that's dual-height and has handles is the G7273. I also have a 3rd party vendor dual height bus+NPG grant card. I suppose it shouldn't be too hard to make grant cards yourself. I think I have my VAX11/780 UNIBUS under control now. I threw out all cards except for the UDA50 pair, put in a new terminator and filled all with appropriate grant cards. Now the UDA50 initializes fine and I get the 8/9 blink fine the port-A light goes on on the RA90. Still the VAX doesn't seem to get anywhere and after a while the lights go off. May be I'm too impatient and should just wait long enough? -Gunther
