A few years back I remember reading on a list somewhere that HP's
(Agilents?) web/ftp archive of documents related to test equipment of
this type was soon to go offline. I recall mirroring a ton of it that I
have stuck away on a set of CDR disks somewhere. I think it was 3-5 CDs
that I archived at that time. Specifically I remember it having a lot
of the 1630/1650/16500 materials. I may have the manuals you want on a
CD here. Reply if you're interested. I probably can't put this all
'up' on a site for everybody as it would have to be cleared by HP for
such use/distribution.
I am the proud owner of an HP1630G with pods. I have used the 1650 and
16500 on occasion professionally. I earlier had one of the earlier 16xx
analyzers and took a stab at one point at making my own pods for it. It
was much slower than the 1650 tho.
I'm surprised that nobody has made replicating these pods in some
fashion into a published project somewhere. It seems like a worthy
design effort that many people would benefit from.
My guess it that it will work, but you probably
won't be able to run
at the specified maximum speed.
That's what I thought.
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.
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. In other words, I'd be inclined to make up
kludge-pods for this
analyser and at least try it out.
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...
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.
Later.
