It would appear that my 3478A is in a non loading tristate mode
until it is addressed, and you are relying on the devices on the
bus to do their own pull up. Clearly that isn't always going to
work.

It thinks the 3478A should be at a different point in the handshake
sequence than the 3478A thinks it should be in. The main clue is in
that the Prologix restores itself when I disconnect it from the 3478A.

Sending T3 locks up the Prologix.

3438A, which is about as old as GPIB
gets. Also with a 3437A, which is pretty old too.
Something is broken here. The prologix is probably violating some timing
requirement in the handshaking, and the 3478A isn't playing along.

sically, if I do any commands that require bus activity, the Prologix
locks up and refuses to respond to even the ++ver command. When I unplug
the HP3478A, the Prologix once again finds its happy spot, and responds
normally.
Any ideas?
