My Tek 1230 is
definitely plain old IDC, and that
model is worth up to and including nothing without the
probes. Probes are $400+ (without the grabbers!). I
have 3 and have turned down an offer for $300 for one
of them.
Just out of curiosity, what's the speed rating of your 1230? My HP
1651B can
do 25MHz state and 100MHz timing.
My first logic analyer, which I still use if I need more than 3 channels,
was a Gould K100D. It came without pods, but I did get the service manual.
The inputs to the analyser were differential ECL signals. I wired up some
10124 (TTL-ECL translators) to make a TTL input pod for it, cabled up
with IDC cable.
I've never tried it at 100MHz, but it works fine at lower frequencies
(e.g. to trace PERQ microcode, etc).
I suppose I can always try IDC cable. It's not
exactly expensive stuff and
there's a good chance of it actually working. If I can't get any HP probes
My guess it that it will work, but you probably won't be able to run at
the specified maximum speed.
and the seller won't refund me for the analyser,
it's always an option.
My expeirience is that for classic computer work, any logic analyser,
even a 10MHz one, is a lot better than nothing, provided you know what it
can and cna't do.
In other words, I'd be inclined to make up kludge-pods for this analyser
and at least try it out. I don't know what machines you normally work on,
but I suspect it would be easily enough for 8 bit micros, HP calculators
(including desktops), and so on
