Among the odd HPIB things I'd like to get working, it would appear I can 
send things to a 7475A set to address 5 per the driver, but it never seems
to get all there.  Is this an interface that requires a read for every write?
Also, is it trivial to modify the ct driver such that it sees a 35401 as a
9144?

TIA, and sorry for the bandwidth if I missed something.
