No, I think I have 4 of them (!). The Goold I just mentioned, a
cheap-n-nasty thing designed to trace microprocessor programs (the pod
has 4 40 pin headers, you connect a ribbon cable ending in a DIP clip to
one of them, I think they're for the 6800, 6802, 6502, Z80), A Tekky
development system which happens to have the 8-channel logic analyser
option in it, and, of course, the one I use all the time, a LogicDart.

Mu Gould has full GPIB control, you can even display messages on its
internal display, sent from the GPIB port....

I'll say! Good pod/probe sets are not common, and not particularly cheap.
If you buy a second-hand analyser without pods/probes, make sure you can
either get them, or can get the spec of the interface to the analyser and
that it's nothing too exotic (most of the older isntruments used
differential ECL signals, which are not too bad).
