This was where he tried to put a mainframe on a 6" wafer. It was a failure, pushing the limits of LSI technology at the time. I went to their final auction in 1989. In the lobby of the building was Gene Amdahl's first computer, not for sale. It was very interesting. I wonder where it is now? It was destined to be saved. Paxton Hoag Astoria, OR

Columbia

by micheladam＠theedge.ca

I'll venture this guess: Concorde Only one loss of craft and passengers & crew. Statisticaly, measured in passenger/kilometers flown, it went from one of the best safety record to one of the worse, since there are so few of the planes...

OT: Anyone in/near Cambridge, MA; Kansas City, KS; or Detroit, MI looking for IT work?

by erd_6502＠yahoo.com

I would like to share in my recent good fortune with folks on the list (and pick up a referral bonus, naturally ;-) by attempting to hook people up with internal job postings. Write me off-list (erd_6502(a)yahoo.com) and tell me where you are at (from the above list of Cambridge, Kansas City or Detroit) and I'll send back job decriptions for those locations. Unfortunately, not much looks like ClassicCmp-type stuff (except the Mac Software Engr position in Cambridge), but we all gotta have current skills to keep on the treadmill. If you don't live within commuting distance of the above places, please don't write and ask me what's available - The openings for tech types are where I've described. Enjoy, -ethan

HP 5423A analyzer

by jwest＠imail.kwcorp.com

I just receive an HP 5423A Structural Dynamics Analyzer. I have no interest in it, but being curious, what the heck is it used for?? From googling I get the impression it does fourier modal testing? Jay "Idly curious" West --- [This E-mail scanned for viruses by Declude Virus]

PDP-8: (and others) anyone tried NVRAM simulation of hard drives?

It is similar to the 8/I external bus which is a daisy chained bus with 10 or 11 cables for full version.

A quick google di not reveal any source.

The book in question is "PULSE: An > Ada-based Distributed Operating System". Ian Wand has just retired from Computer Science at York, but Andy Wellings is still there. I'll ask Andy about that... CompSci had Vaxen and unibus 11's (I've got one of them), but I didn't know they ever had any small QBus machines. -- Pete Peter Turnbull Network Manager University of York

Emulex QD 211

by Innfogra＠aol.com

A quick Google search nor looking through Emulex's site was I able to find out what this card is? The actual number is QD2110202-00 rev L. From the connectors it is either ESDI or a MFM hard disk controller for Qbus but I am not sure which.
