Hello list,
I've had this HP logic state analyzer for many years now, but never found actual use for it and thus never used it. So I decided that a new home would be more suitable for it. The analyzer comes with the option to debug and analyze 8080 microporcessors. Probes are provided, but no manual. However, there is a small command overview on the front of the keyboard.
The system completes the selftest and I did let it run for two hours yesterday. No more tests done, but if anybody wants me to do a specific test, then I can do it, provided you explain to me what to do.
Pictures are under

Make me an offer via private reply. Pick-up in Bonn (Germany) or international shipping possible. However, keep in mind that the system weights 13kg (29 lbs), so shipping is not going to be cheap.
Cheers,
Pierre

HP 4952? I have two with tapes from the old days (they contain a
formatter, and we did wipe some scratch tapes for storage of our
analyzer programs, including a PU Type 2 BIND simulator that filled
the program memory, but it worked well enough for us to debug SNA BIND
sequences in the absence of a real PU Type 4).

Now I'm triply bummed that he was sick, and didn't manage to make it to the
last VCF East.
He was one of the giants - somewhat unsung, but a giant. RIP.

We will be up for getting one to round out the HP display here
When I was in the biz they were out there but we did not sell any parts
for them,
I remember some developer friends complaining that the A version of
RTE version of the os did not have SESSION
Let us know if you have one folks even a dead one as it is a physical
display only situation
*(However if a complete setup running was to be had....that might be
fin too!)

The PDP-11 at the RICM says "dec pdp 11" on the system configuration paper
label on the back, and "M11 15" and "4720" on the metal tag. Unfortunately
it has an OEM front panel.

Would anyone out there happen to know the whereabouts of one or more
specific videos that were hosted on the Microsoft research web site maybe
10-15 years ago, starring James Gosling, where he talked about NeWS
(Network extensible Window System)?
I may even be able to dig up the URL for the video(s) when I get home, but
it's been dead for a long time now.

Here's an interesting tid-bit.
I just got off the phone with the AT&T corporate archives, where I had
hoped to find schematics and internals documentation for the AT&T 3B2.
They do have it, but unfortunately they will not give access to any
of it because they still consider the 3B2 to be proprietary
information.
I'm disappointed, obviously, but not all that surprised. 25 years is
not a long time for a company like AT&T, and I understand the 5ESS
system still runs a 3B20 emualtor. They may even still have support
contracts for 3B2 installations, I'm not sure.
Anyway, all that aside, will soon have access to a couple of 3B2/310s,
so I hope to continue reverse engineering the hardware directly.

In spite of the floppy drives, I don't think these are general-purpose
boxes. The thing that strikes me, given the displays is that they might
be graphics workstations of some sort. There's just too much there for
a simple floppy-based computer.
The problem is that Hitachi is a huge outfit with tendrils in all sorts
of industrial areas.
