> The BBN CPUs are odd in that they don't plug into a socket This is a BBN Butterfly system. The processors interconnect through a "Butterfly Switch" I have to check with the Computer Museum, but this may be the only surviving system. It's a drag you weren't able to save at least one of the chassis. try googling "bbn butterfly switch" Butterfly Switch A parallel processing topology from BBN Advanced Computers Inc., Cambridge, MA, that mimics a crossbar and provides high-speed switching of data between nodes. It can also be used to create a hypercube topology.

Stump the Historians at the Computer History Museum this Friday

> does anyone know what happened to the sigma computer I asked Lee Felsenstein, and it was scrapped. Some of the documentation and a few of the magtapes are at the Computer History Museum. I don't know if enough of the software survives to get it running in simulation. Even if it does exist, according to the histories I've read of the Community Memory Project, the mass storage interfaces were custom.

BBN and SMS pictures. More

by rigdonj＠cfl.rr.com

Added more pictures. Here <http://www.classiccmp.org/hp/bbn/multibus/> are pictures of the Multibus cards that are used in the BBN. I don't think I mentioned it but the BBN has two card cages plus a place for the Switch card. As I mentioned earlier, the BBN card cage has no sockets and all the card connections are made through cables on the front edge of the cards. In addition to the BBN CPU card card, there's also a Multibus card cage for the IO controllers and such. These house an IKON DR-11W emulator card <http://www.classiccmp.org/hp/bbn/multibus/DR-11W.jpg> that's used to talk to the BBN CPU cards. A Burr-Brown 830-72 72 channel TTL I/O board <http://www.classiccmp.org/hp/bbn/multibus/Burr%20brown%20830-72.jpg>. A CMC or Excelan EXOS201 Intelligent Ethernet controller board <http://www.classiccmp.org/hp/bbn/multibus/CMC%20Ethernet.jpg>. A Data TRanslation DT5712E high performance A/D converter card <http://www.classiccmp.org/hp/bbn/multibus/Data%20Acq%20module.jpg> and a NCR HPSIO card with 8 RS-232 ports and 1 parallel printer port. Joe Here are some pictures of SOME of the stuff that I got last weekend. Besides a huge box of manuals that I've sent to Al, I found five BBN computers and I'm attempting to rescue enough of one to make a workable system for Tom Uban. Plus all the cards out of the other ones for him for spares. The BBN chassis is just too big to deal with but I got ALL the cables, the complete PSU (on the back panel!), the multibus card cage (and all the MB cards) and the switch card that lets all the CPUs talk to all the other CPUs. The BBN CPUs are odd in that they don't plug into a socket so the card cage isn't absolutely necessary. All the power and signals go through connectors on the front of the card. Warning: this is a SCRAP place and some of it isn't pretty! <http://www.classiccmp.org/hp/bbn/> Here's also some pictures of the internals out of one of the 7 1/2 (yes half!) SMS Multibus computers that I rescued. These are pictures of the card cage and cards from the 1/2 computer. The scrappers had already started on it but I managed to find the cards, hard drive, floppy drive, etc. <http://www.classiccmp.org/hp/sms1/> I'll post more pictures and details about these later. I also rescued three Masscomp Multibus systems but no pictures or anything for them yet. OOPS! I forgot, I also rescued four Intel 86/384 computers and a MN-26C radio compass on Saturday. More about those later too. Joe

tracing out schematics

by melamy＠earthlink.net

yes, those mains light switches are complicated... -----Original Message----- From: der Mouse <mouse(a)rodents.montreal.qc.ca> Sent: Nov 18, 2004 10:14 PM To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk(a)classiccmp.org> Subject: Re: tracing out schematics > You will _never_ successfully trace a schematic you don't understnad. I think that's a bit of an overstatement. There have been devices that I understood not a lick until I sat and studied the traced-out schematic for some time. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

OT: OS/X - X11

You can download it from various places online, or it comes with OS X.3 (but I don't believe it is part of the default install, so you have to choose to install it). I know OpenOffice was ported to OS X for use with X11. I just don't know how much was involved beyond a recompile. -chris <http://www.mythtech.net>

Cool finds: Apple, Be, Commodore

by julesrichardsonuk＠yahoo.co.uk

Picked up some nice stuff just now: Apple Powerbook 170 Apple /// + Profile unit Apple Lisa BeBox + manuals + software Commodore PET 3032 Commodore PET 8096-SK Only just got back so I'm only just about to start poking around inside things :) What's more impressive is that it all works apparently, apart from the Lisa... I'm sure I'll have questions to follow as I pull cases off... cheers Jules
