Recommended logic analyzer/scope tools?

Ah yes, fine instruments. I have an old Model 8 (I can't remember the version), a DA114 (early digital meter) and, of course, a Valve Characteristic Meter Mk 4. For the people across the Pond, AVO, of course, comes from the initals of Amps Volts, Ohms. It was the brand name of one of the first multimeters in the UK (the 'Universal AVOmeter' was around before WW2 I think, 'Universal' meaning it had AC and DC ranges). Amongst older engineers and scientists, 'AVO' is used as a generic name for any multimeter over here. So would I. And an HP3468. I think that's the model, the one with an HPIL interface on it. I have an HP3421 logger which is very nice, but you need a computer/calculator to control it. It has no front panel controls or display. -tony
