:o Indeed, there is! Damn you, I've already got too many projects piling up! ;) I'd love to try to have a go at this and see if I can do something about the couple problems it supposedly has.

Why the hell would he have blurred out the part numbers in the photo?? :wtf: They're all in the schematic...

PaulAm:
Somebody mentioned the 5000 series.  These are mostly low bandwidth scopes, but they were like the 7000 series with bunches of plugins.  I think most of the mainframes were in the 15MHz BW range, although one went to 50MHz and there was one that had digitizing ability.  I think these are most useful for either audio work or if you have a specific plugin (eg spectrum analyzer or curve tracer) that doesn't need a high bandwidth scope.  Working with high speed logic we tend to forget that there are lots of applications for a low BW scope.

Yup, got a navy sticker on it. I mainly went with it for the price. It was definitely treated like a bit of military gear, hence the coax falling of the bnc connectors.
