I'm trying to get a confirmation from other list members. =)

RS-432 really won't do me any good. So, is there always an RS-323 console on
the DB25?

Well, we have several. One MVAX II/GPX, one MVAX 3100 and one MVAX II whose
state is unknown for lack of time and interest (we're having enough trouble
with the DEQNA in our GPX).
And running such a machine without ethernet is no fun, I'm so spoiled
nowadays. =)
