Unknown Z80 CPU board and backplane ID anyone?

by binarydinosaurs＠gmail.com

Hi folks, A friend of mine in the UK is looking for any info on the following boards. The CPU board is marked ?VA 03-907023-00? and features a Z80 with 16K RAM and an 18.432MHz crystal. The backplane is also VA and has 11 132-pin slots that aren?t all identical implying usage for different cards in those locations. Voltages are +5/-5/+12V.

Unknown Z80 CPU board and backplane ID anyone?

Agree about Varian trademark. In 1937 the Varian brothers developed the Klystron tube. In 1965 Eitel-McCullough (EIMAC) merged with Varian Associates, but in 1995 the EIMAC division was ?spun off? (now part of CPI). In 1999, the company was reorganized into three distinct businesses: Varian Medical Systems Inc., Varian Semiconductor Equipment Associates Inc., and Varian, Inc. == The Card Edge connectors on motherboard are Sullins Connector Solutions, Inc. http://sullinscorp.com/catalog/ MPS-0125-50-DW-5H Edge Card Catalog http://www.sullinscorp.com/pdfs/edgcards-catalog.pdf Card Edge Connector, 100 Contact(s), 2 Row(s), Straight, 0.125 inch Pitch, .025?

Global Village 56k modem for shipping

by mtapley＠swri.edu

All, pursuant to the modem discussion the last couple of weeks, i searched briefly and came up with: Global Village Teleport 56kbps fax/modem in original box (opened and inspected, not tested), includes power supply and software on CD (for Mac OS 8). Cable connects to the Mac serial port (round DIN connector) For cost of shipping; I?ll add some bubble-wrap to the box to kee things from rattling inside and if you are concerned about the original box I?ll add another layer outside. - Mark 210-522-6025 office 210-379-4635 cell

Extraordinary creativity, remarkable breakthroughs, fierce competition, hubris and heartbreaking betrayal dominated behind the scenes of General Magic. While some never recovered from the failure that accompanied its downfall and bankruptcy, others went on to soar. The lessons learned at General Magic were instrumental in the creation of the iPod, iPhone, Android, eBay, even in the corridors of President Obama???s White House. And although General Magic died, the concepts and the people who worked there went on to change how the world connects today. Described by Forbes as ???The most important dead company in Silicon Valley??? and combining rare archive footage with contemporary stories of the General Magicians today, this documentary tracks the progress of anytime, anywhere communication from a thing of sci-fi fiction to our modern day reality.

Troubleshooting HP 2116B

by gerardcjat＠free.fr

Christian, I absolutly agree with David s post. Back in the ' '70 when I was maintaining 3 x HP 2116 B running 24/24 7/7 FOR around 10 YEARS, the ONLY memory related problem that I got was traced to a faulty transistor !! ( But I do not recall exactly, may be it was on a Driver Inhbit Card ) Anyway, from this only one case , not statisticaly signifiant ;-) the problem was a Tx, not a C.I. Wish you the same ...

Microware OS-9 68000 SPF

by david＠thecoolbears.org

Anyone familiar with the SPF file manager on Microware OS-9? I have an MVME162 processor and for no good reason, other than an intellectual exercise, I've decided to try and get OS-9 68000 running on it. Mostly this has been a pretty simple exercise, since the necessary ROM images are on the Internet, however, the one thing that I can't seem to make work is SLIP (or PPP for that matter). I have the MVME board connected via an RS232 connection to a Raspberry PI. PPP doesn't work at all but SLIP works partially. I can PING from the PI to the MVME and from the MVME to the PI. I can send TCP traffic in both directions. I can send UDP traffic in both directions. When I try to start a telnet session from the PI to the MVME, it seems like the session is established: Trying 192.168.2.2... Connected to 192.168.2.2. Escape character is '^]'. But I never see the login prompt on the PI. Pretty much the same thing applies to other telnet clients including Windows, NetBSD VAX and 211BSD on my PDP-11. Furthermore, I see that the connection handler in OS-9, telnetdc, is started and also login is started 20 0 0.0 128 48.00k 0 e 0.03 0:00 telnetdc <pks01 21 20 0.0 128 24.00k 0 e 0.02 0:00 login <>>>pks01 40 0 0.0 128 52.00k 0 s 0.12 25:42 telnetd <>>>nil but I never get a login prompt at the PI. Any suggestions?

Tim Paterson / QDOS lecture @ VCF West next weekend

by cctalk＠snarc.net

I am excited about this!! Tim Paterson, of Seattle Computer Products, is speaking at Vintage Computer Festival XIII next weekend (August 4-5). The event as always is at the Computer History Museum in Mountain View, California. Tim created QDOS - Quick & Dirty Operating System -- which was the basis for Microsoft's MS-DOS. Tim rarely (if ever?) gives historical lectures, so this is a coup for the hobby. Everything you need to know about VCF West -- online ticketing, all the other speakers, exhibits, consignment, etc. -- is on the VCF web site at http://vcfed.org/wp/festivals/vintage-computer-festival-west/. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan at vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation
