I don't
know what machines you normally work on,
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. but I suspect it would be easily enough for 8 bit
micros, HP calculators
(including desktops), and so on
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.
FWIW, I do a lot of my work with a 3 channel logic analyser (HP
LogicDart), and I find that to be enough. Often all I need to look at is
one signal against an enable or something like that. Actually, a
single-channel analyser is sometimes enough.
