That ubiquitous black foam

After 4 years, it was nothing but a gooey yucky mess. And that was the time in the shade; Ozone+sunlight was far far worse to all sorts of stuff. Bike tires made out of synthetic rubber would last for a few months; real rubber had a chance of lasting a year or two. Good that you found a source for small quantities; I always got the equivalent from the HVAC suppliers and they sold it by the truckload only! Tim.

That ubiquitous black foam

by IanK＠vulcan.com

I haven't seen anyone discuss this (nor is Google showing anything), so for all of you doing DEC restorations out there, I thought I'd pass along something I learned. DEC loved that black filter foam that falls apart after fifteen or so years. I'm restoring a couple of VAX-11/785s and they were liberally dusted with black foam detritus. So I took a piece that wasn't beyond recognition to a local shop here in Seattle called Friendly Foam (www.friendlyfoam.com). They identified it as "40ppi (pores per [square] inch) reticulated foam." They were also kind enough to sell me several square feet of it. They warned me that yes, it will still fall apart after a couple of decades, but for now it looks sooo nice. The machines I'm restoring have good paint, so with the new foam in place they look like they just left Maynard. It's funny how the little touches make such a difference. BTW, they also found adhesive-backed foam that is an exact match for the stuff DEC used on the cardcage cover panels. I hope this helps everyone who's trying to keep their Olde Beastes healthy and happy. - Ian UNIX is user friendly. It's just selective about who its friends are. Ian S.

The Crossbar System That Controlled MIT Trains

by johnmcnamara1＠verizon.net

During the period 1962-1966, members of the Tech Model Railroad Club of MIT conceived and constructed an unusual use for telephone equipment that functioned essentially as a combinatorial network. Specifically, they used five10x10 crossbar switches and more than 100 wire-spring relays to construct a control system for their large HO-gauge model railroad. Pictures of this control system can be seen at http://tmrc.mit.edu/progress/images.tcl?year=2002&month=5&day=26. Like all good electromechanical telephone systems, it remained in service for almost 40 years, even surviving a move between buildings. In 2002, it was replaced by an electronic system (not related to telephone systems) and retired to the New England Museum of Telephony ("The Telephone Museum") in Ellsworth, Maine, where it has been stored since that time. Unfortunately, the folks at that museum have decided to "de-accession" it, as it is not really part of their mission, and is taking up too much space. It is also likely to get damaged by future activities near its present location. If you have confirmed that someone or some organization would like it, please let me know. The deadline before scrapping begins is October 15th.

DEC 5' cabinets for sale cheap! - LIVERMORE, CALIFORNIA

by sellam＠vintagetech.com

Sorry, I forgot to mention that I'm in Livermore, CA. No, they aren't radioactive. These were employed for use in mobile whole body counters. The nearest they got to anything nuclear was if someone who was heavily irradiated walked into the trailer where these were installed. I don't think shipping would be worth it unless you really want one. This is more of a hail Mary before they get scrapped. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

something's missing from my kit

by jeffj＠panix.com

I have a Nicolet Z80 NICE in-circuit emulator. Unlike a logic analyzer, it MUST replace the CPU (cannot just clip over the CPU since some signals are asserted or blocked). 1) The 40 pin DIP's pins are on the bottom of the box so it plugs in directly, if there's space. If there's NOT enough space, it comes with a ribbon cable but with .6" 40 pin dip-PINS on both ends. Mine came with a hand-made PCB with 2: 40 pin sockets hand-wired together to act as a F-F adapter. Is there are more "graceful" way to handle that, such as a female/socket 40 pin DIP connector directly to ribbon cable? There are compact gender changers for DB9/DB25 RS232 connectors, why not something similar for 40 pin DIP? 2) What if the CPU is soldered to the board? Must I desolder it entirely, or just certain pins? Thanks! Jeff Jonas jeffj at panix.com

DEC 5' cabinets for sale cheap!

by sellam＠vintagetech.com

I have about 7 complete 5' standard 19" cabinets for sale. I'm not sure if they are genuine DEC (they are branded Helgeson Nuclear Services) but they used to hold DEC equipment. See them here: http://siconic.com/crap/racks/ They have front and rear (locking) doors (some have key, others do not), removable sides, an internal power strip, and come with optional blower. I'd like $25 a piece, or give me $30 and I'll throw in a blower. The price will approach scrap value as the quantity you buy increases. I mean, really, offer me anything more than scrap value and you can have it. Priority (and the lowest price) goes to someone who says they want them all. These will go to scrap in a few days if there are no takers. Please contact me directly!
