Well, we know one works in that it was running while we were there. Booted RT-11 off the fixed platter and then had to do some file deletion on cartridges.
As for the other two drives, we'll have to see as Rob finds time to check them. We won't be surprised if they have problems as they may well have earlier drives replaced by the functioning one. The power supply had been pulled out of one, but was still around. There are two spare logic boards for the drives, but I expect problems are more likely to be in the HDA area.
Should we end up finding a fault and succeeding in a repair, will let you know.
