An interesting 3 hours on PBS last night: - 'Steve Jobs - One Last Thing': No description necessary. - 'Long Distance Warrior': McGowan/MCI's David & Goliath battle with AT&T and disastrous merger with Worldcom. - 'Digital Man/Digital World': Ken Olsen/DEC's growth and ultimate decline. (No doubt everyone here except myself had already seen this one ;-) Interesting comparison of the different styles and personalities of three men who profoundly influenced the tech world of today and their companies. Thoroughly enjoyed it. m

Vaxstation 3100 of odd sort on epay

by jwsmail＠jwsss.com

This might be a tempest or shielded vaxstation? Anyone speculate or know for sure. The vendor may have these mixed in as equivalent to their other vaxstations. If you search for "DEC vax VS42A-BN" you end up back at the vendors listing for the ones with plastic covers. I didn't turn up any info yet, not hoping to. but the thing has what appears to be optical, and a huge connector which may be shielded SCSI on the back. I can't tell from the front, but there may be a hatch to allow it to be opened and a floppy inserted, not sure from the photos. VINTAGE-RARE-DEC-DIGITAL-VAXSTATION-3100-PF-VS42A-AA-RF-VS42A-BN-COMPUTER-SYSTEM/ http://www.ebay.com/itm/370930391341 Kind of an interesting device. I looped back into the vendors listings to this auction for the plastic topped version, by the way VINTAGE-DEC-DIGITAL-VT1300-VAXSTATION-VS42A-BB-COMPUTER-SYSTEM-VT-1300-TERMINAL/ http://www.ebay.com/itm/370912245260 It is badged VT-1300 so may not be a vaxstation. And the other box may be one of the VT-1300's that is tempest or shielded. thanks Jim

Tek 40xx computer users

by rdawson16＠hotmail.com

I bought the Tek 4051 on ebay today; Jason brought it to my house and it works perfectly, with about a half hour of programming instruction my 12 old daughter was plotting a cat face. https://www.facebook.com/Thelma.Franco/videos/10154277153852670/ I would like to get in touch with other users of this first personal computer, and find additional resources. Do you know where I can find an archive of BASIC programs for this? Has anybody built plug in cards in the back, mine came with a realtime clock and a "file manager", I do not know what that one does. I have some Tek scopes with IEE-488, and I will see if I can get the IEEE interface working. There was a DC300 tape in the machine: biorithm craps blackjack artillery tanks weatherwar The belt is broken in the tape, I have ordered some new DC300's and will transplant the tape. Any resources will be welcome! Randy

DS12887 pcb substitute with battery

by cctalk＠ibm51xx.net

Jon, Then why not use a dip compatible version of the DS chip? I mean yes this allows for switchable battery which is very nice but SMT soldering is not for everyone. I wonder if there is a way to determine if there will be BIOS issues by switching the DS12887? -------- Original message -------- From: Jon Elson <elson at pico-systems.com> Date: 1/22/17 9:16 AM (GMT-08:00) To: General at classiccmp.org, "Discussion at classiccmp.org:On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: DS12887 pcb substitute with battery On 01/22/2017 10:07 AM, Ali wrote: > Al, > I thought the problem with switching these chips was that part of the ROM code was embedded in them? I.e. it isn't just an issue of battery? Am I wrong? If I am then why not use one of the replacement chips that are available? > These don't have a lot of memory on them.? many early PCs stored some config info there, but generally the BIOS can reconstruct it if it isn't there.? I suppose there is a possibility that random data in the CMOS memory could cause the BIOS to try to use unavailable features and hang.? I don't think anybody put actual executable code in there. Jon

No you are not. I use (al)pine on my OpenVMS system here as well as my main Linux host. I have mail going back to 2004 here and since 1996 at another public access Unix host I use. It's great when I'm out of town and can ssh in from my phone and check the mail. :) Pine does most everything I need without having to worry about malware, phishing, etc ... the beauty of text. Fred

What is this bus?

by mhs.stein＠gmail.com

I have a bus backplane here, very similar to an S100 backplane but the 2x50 connectors use .1 in spacing instead of .125 and the supply voltages are regulated +5 and +/- 12V. I also have the power supply; what are they from? TIA, m

RL02 to image file

by jcwelch＠hal-pc.org

Hello, Does anyone have a setup to image RL02 packs to a pc file that can be mounted with simh? I have a couple of dozen I would like transferred because I am downsizing. I have a bunch of gear I can trade, also rum and/or dollars. Hopefully you are close to Houston. Sincerely, John Welch

HP 9836 systems and Fuji Pictrography 4000 printer available

by bobalan＠sbcglobal.net

Spring cleaning time! I have three vintage HP 9836 computers, two monochrome monitors, one color monitor and three printers. I'm sure they are going to need work to get running. No testing has been done. Could probably get two out of the three working. Somewhere I have a few various I/O cards also that will be included. Photos can be seen here: http://anifur.com/clist/ Pickup in Santa Cruz, CA, I just don't have time to (or the back) to pack and ship, though I can help load. -Bob -- Vintage computers and electronics www.dvq.com www.tekmuseum.com www.decmuseum.org

Firefly dual processor card

by spacewar＠gmail.com

Did you get an actual Firefly (research) board, or a prduction VAXstation 3520/3540 board? I don't think you're likely to find schematics or pinouts for either, but it's not impossible to find 3520/3540 stuff, while I've never before heard of anyone encountering any actual Firefly boards in the wild.
