That's what I thought.

Well, in this case, I'm still trying to get the hang of the front panel
controls on the 1651B. The badly-OCRed copy of the Getting Started Guide I've
got is just about usable, but a lot of the OCR errors are subtle - changing
commands and suchlike in non-obvious ways.
I'll probably buy a manual later, but the manual comes after the pods and
cable kit on my list of priorities.
Speaking of manuals, I've got the service manual for the 1652B - no
schematics, just a boardswapping guide. Yecch.

I've got it hooked up to a PICmicro development board - it's rigged up to the
1-wire bus output. At least I know Pod 1 bit 0 works - now to test the other
31...

8-bit micros mainly. 6502, 8080, Z80, that sort of thing. I was going to get
one of the 80-channel HP analysers, but I decided I didn't need to probe that
many lines at once - I don't do much work on 16- and 32-bit CPUs.

If I need an 80 channel analyser, I'll probably build my own - it can't be
that hard to shove a bunch of FIFOs and an oscillator on an ISA-bus card,
then write some software to drive it.
Later.
