Looking for the Tek 465 of Logic Analysers

Ditto. Well, I can't remember which model I was given, it's the one that's maxed out with 'state' channels, but only the basic 'timing' channels. The manual is excellent (and available, AFAIK, from whoever Agilent became). The only schematic you don't get is that of the video monitor -- and be warned that is a bit unconvenitonal as the scan lines are vertical (across the short dimension of the CRT). But you do get schematics of the CPU board, state and timing boards, PSU, etc. One practical thing I like is that the pod cables are 'captive' (held on by a screw-on metal cover plate) so the pods are less likely to go walkabout (you've not seen my workshop :-)) As I mentioned earlier, it has both HPIB and HPIL interfaces. In theory you can control this thing from an HP71B handheld (or an HP41 calculator?) An HP1631 would be fun (it has a DSO board at the bottom as well as the LA functions). -tony
