A friend of mine and I worked for Arium, which are well represented on
ePay. If anyone is interested we have a pile of probably 20 analyzers,
which are probably not going to get used. I am in posession of a 16500C
and quite pleased with it, though the ML4400 can run faster with more
channels.
We do have the pods, and manuals. Would consider requests for any or
all of the pile. I talked to my buddy, and pretty much are willing to
let it go.
The pods would mostly be for the ML4400, though I think I have a working
4100 with one pod set.
Arium had started making a trace product which went under a Pentium and
the ML4400 with a third party (paratronics or such) made capture board
to capture the 133mhz bus. At the time it was clunky, but INtel
couldn't keep up with the bus w/o a "deathstar" HP 16xx or 16xxx setup
to capture all the pins which cost way up near $100k.
So they kept making the 4400's plus the trace unit, called a TRC54 for
quite a time longer after they made any standalone analyzers. And
almost none with the pods for the TRC54 / ML4400 combo.
So what you see are the ML4400 units with two capture cards and 200
channels of trace.
Note also with the ML4400, for what it's worth the actual loop from the
pod to the clip is also active with a mini coax and balanced resistor
network on both ends, so you have to have the ML4400, pod, and the lead
set (or make up the leads, I can get you the formula).
The roll of mini coax was snarfed by another employee for scrap, so you
are on your own finding that. It was quite expensive and hard to get,
and actually looks like the small 30 guage stranded lead wire, but
actually is coax.
Other useless data is that the drives are 720k drives if anyone wants
one that won't read 1.44 (there are a very few that had the 1.44mb
units, but for the most part are 720k standard).

Weirdstuff is where I got the main unit (
actually a 748, diskless
version ). I got it at auction but didn't get any probes. Did you see
probes and if so, where would I look for such things? I'd be interested
in a copy of the manuals, especially if they have schematic but even
operation would be nice to have. Yes, this is the box that had a CP/M
based OS ( when used with the disk models, like the 764 ).
Not to rain on your parade, but I've long been fascinated by the
numerous offerings for logic analyzers on eBay--all without pods--and
all advertised as "working".
I've wondered if there's an underground smuggling ring for those
things were they all end up in Paraguay. Or maybe the bottom of the
Sargasso Sea is carpeted with discarded logic analyzer pods...
