Offer: HP 1611A logic state analyser with option A80 for 8080 microprocessors

by p.gebhardt＠ymail.com

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 http://www.digitalheritage.de/other/hp_1611a/ 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 ------------------------------------------------------------------------------- Pierre's collection of classic computers moved to: http://www.digitalheritage.de

Serial analyzers (was Re: VAX 11/730 quickie)

Notably, I specifically avoided one with the same type of tape drive; I got one with a nice, reliable 3.5" floppy drive! ;) 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). -ethan

Who, on this list, Owns / Collects / Plays with an HP1000 A or L series ??

by gerardcjat＠free.fr

Just curious. It seems ( at first ) that most collections stops at 21MX ( M/E/F ) era. Am I correct in my view ?

PDP-11/20 vd one that just says pdp 11 what are the date differences?? OEM?

by michael.99.thompson＠gmail.com

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. -- Michael Thompson

NeWS video(s) with James Gosling?

by echristopherson＠gmail.com

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. -- Eric Christopherson

The AT&T 3B2 is still proprietary

by lists＠loomcom.com

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. -Seth -- Seth Morabito web at loomcom.com

Australian CP/M era computers?

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. --Chuck
