stuff to donate

Id like the Dataphone modem. Readers digest version is I grew up watching the dataphone infrastructure be dismantled. My (rip) uncle's house was literally lined with woodgrain panels from the front doors of the equipment cabinets, with the dataphone logo on every one lol. I gotta get a pic one of these days we still have the house. >> 2. An AT&T Dataphone II 2224B modem, with power supply. This was >> hot-shit in it's day. It would do 2400 bits/second.

K-Fest carpool?
by Evan Koblentz 03 Mar '17

03 Mar '17

I've always wanted to go to K-Fest. I may apply for one of their "golden tickets" this year, however that still involves getting one's self to Kansas City. Is anyone interested in getting together with a few people for a carpool? Obviously not in my tiny car :) but I'd be happy to split the driving and gas $$. Paying for a flight or the cost of all that gas by myself would be beyond my means right now. ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation

FS: Several 1960's Raytheon Nixie Tubes and Control Boards
by Systems Glitch 28 Feb '17

28 Feb '17

I know there are several people who like Nixie tubes on this list, so: Links: http://www.ebay.com/itm/272572418459 http://www.ebay.com/itm/272572420943 http://www.ebay.com/itm/272572429330 Two sign indicators and one numeric tube. All tubes have been tested with a homebrew switchmode supply built to drive Nixie tubes. One of the sign tubes is obviously heavily used, the glass is darkened in the front. All three boards include a socket with the full pin count populated, which may actually be more valuable than the Nixie tubes, especially the sign tubes :) There's also a great mix of really old TTL on these boards. Some of it is packaged in blue plastic DIPs made by...Sprague! I didn't know they *made* ICs. Appears to be standard 7400 series TTL. The board with the numeric tube includes a white ceramic TDD1100 which appears to be compatible with the usual 7441 or 74141 Nixie driver ICs commonly found in 1970's equipment. Tubes are tested, control boards are not. Thanks, Jonathan

Replacement VCF East speaker needed
by Evan Koblentz 27 Feb '17

27 Feb '17

Everyone, Oscar V. had to change his spring travel plans due to a family emergency. He sends his apologies, as he wanted to have an exhibit and give a Friday class about his Pi-based replica kits. We need a replacement topic/speaker. Emailed me privately (evan(a)vcfed.org) ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation

IM-6100 Availability (PDP-8 on a chip)
by Systems Glitch 27 Feb '17

27 Feb '17

All, I had a component supplier get back to me today -- they appear to have several *hundred* IM-6100s in stock. Looks like I'll be able to do a bulk purchase on these to at least fill OSI 560Z kit needs. Contact me off-list if you'd like to purchase some of these CPUs independent of a 560Z kit. Information: the IM-6100 is an Intersil product that implements most of a PDP-8/e on a single chip. It doesn't handle memory management like the later 6120, but you can implement it yourself. It's used in the Ohio Scientific 560Z "Processor Lab" to allow PDP-8 code to be executed on an OSI system. Thanks, Jonathan

Virtual Computer Museum Tour and (paid) Help Wanted
by rar 27 Feb '17

27 Feb '17

As of last evening, I have the beginnings of a virtual museum ( https://museum.syssrc.com/album/pan<https://musuem.syssrc.com/album/pan> ) Enjoy! I am looking to hire an interested party to document up to 1000 objects in the virtual tour. There are two parts to the project: 1) Create a base page about an artifact. For example: a. https://museum.syssrc.com/artifact/105/ b. https://museum.syssrc.com/artifact/personal-computers/410/ I will supply pictures of the actual object. You will write the text, find videos, emulators and provide other information. All the information goes into a Django CMS 2) Tag the item on the VR tour. It requires editing an html document like this: { "pitch": -7.0, "yaw": -15.408, "cssClass": "custom-hotspot", "createTooltipFunc": hotspot, "createTooltipArgs": "Japanese Abacus - soroban (算盤, counting tray) ", "clickHandlerArgs": "https://museum.syssrc.com/artifact/early-computing/20/", "clickHandlerFunc": modalpop, All are welcome to come to Baltimore to visit the real Museum.

museum report
by Evan Koblentz 27 Feb '17

27 Feb '17

I was in our museum from 1pm-4pm today. It was quiet. I feel asleep at the chair of our office PC, so I don't know if there were any visitors! Had a meeting at 4:00 with Fred and two of the Infoage board members about improving the Infoage website. Then I went to the main Infoage staff meeting at 6:30. Only thing going on that affects us is they're having a veteran's day thing on Saturday May 20 with extended museum hours. The rest of us is normal bureaucratic baloney. :) ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)3 educational non-profit evan(a)vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation
