Computer People for Peace
by Bill Degnan 22 Apr '20

22 Apr '20

I was reading through some People's Computer Company newspapers and came upon a reference to a group called the Computer People for Peace. I did some research and found that they were active from 1969-1973 and they put out their own newsletter, based out of Brooklyn, NY. So, for you who care about MidAtlantic history, here is a link to the archive and articles I compiled. http://www.vintagecomputer.net/browse_thread.cfm?id=761 Some of you may not know exactly how militant they were against IBM back then. Someone bombed one of their offices back during this time. I have a 1968 ComputerWorld article about it. The late 60's have a rich computer history if you care to explore beyond the 80's :-) I plan to make an exhibit of some of this at Kennett Classic some day, after the current exhibits are done. Bill

Gallery talk about Univac 490
by rar 21 Apr '20

21 Apr '20

The System Source Computer Museum has been closed due to Covid 19, so we started making video gallery talks. The first one is about our Univac 490 real time computer from 1963. It is about 10 minutes. https://www.youtube.com/watch?v=hq7aVCc2GP8 Bob Roswell https://museum.syssrc.com museum(a)syssrc.com<mailto:museum@syssrc.com>

21 Apr '20

Nowthat Mke Ruane has extended the closure of IA until June, I figured it would be a goodtime to continue the shout out that Jeff Brace started and see how everyone’sdoing. Stuffhere in Brick is moving like Ground Hog Day, although business paperwork seemsto keep me focused if not only for a little bit of time and I have to come backto it later. Waitingon shipments of PCMCIA stuff for the HP660LX so I can play further. Anybodyworking on interesting stuff? BillInderrieden

OT: HP 660LX Color Palmtop PC available
by svcatitc＠aol.com 19 Apr '20

19 Apr '20

HP 660 is up and running. Amazingly, for the age, the NiCd packs charged up fine. Now I am looking for PCMCIA memory for the thing so as to bring over other files and programs, from the main PC's. Once you get used to the stylus operation, it is a neat little thing. Thanks again to Bob Shuster for all his assistance. Bill Inderrieden svcatitc at aol.com svcatitc at aol.com Tue Apr 7 09:23:07 EDT 2020 - Previous message (by thread): [vcf-midatlantic] ACM digital library is free thru 30-June - Next message (by thread): [vcf-midatlantic] Wanted: Disk Jockey 2D/B - Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] So that the final disposition of the HP palmtop is not in question, it has been spoken for. Many thanks to Bob Shuster for his assistance. Bill Inderrieden ---------- Original Message ---------- Jim Scheef js at sdf.orgTue Mar 31 23:21:59 EDT 2020 The HP660 is eminently collectible along with the other four or five models in the HP palmtop product line based on WinCE. The DOS-based palmtops starting with the 95lx are even more interesting although not as 'rare'. Hopefully someone will take Bob's offer.Jim

Re: [vcf-midatlantic] ADM-3A display problem

This project finally got popped of the stack and finished, and I wanted to "close the loop" on it. The culprit turned out to be C112, a 47uF 50V in the monitor section. Ian nailed it. Thank you!

Collection of Commodore items for sale in Facebook Group
by Christopher Gioconda 18 Apr '20

18 Apr '20

Sharing this to everyone because it’s a private group on Facebook and folks may not be members- there’s a pretty impressive collection of Commodore items being sold up in Schenectady NY, but it sounds like the owners aren’t aware of the value of the collection. https://www.facebook.com/groups/2006480029587942/?ref=share is a link to the group. There’s a CMD RamLink, SuperCPU, CMD hard drive, SX-64 amongst others. Good luck, and hope everyone is staying healthy. Chris

InfoAge update from Mike Ruane (CEO of InfoAge)
by Jeffrey Brace 18 Apr '20

18 Apr '20

To All - Due to the continued impact of the coronavirus, InfoAge is now scheduled to be closed until June 29. A further decision to open on June 29 or to remain closed will be made in mid-June. In the meantime, as I mentioned in my March 16 email, some organizations and/or volunteers will want to work on their museum projects, exhibits, buildings, etc. These organizations/volunteers can use their own discretion as to whether or not they wish to work on their sites or various projects. However, many of our volunteers are in the “at-risk” category and should stay at home if at all possible. Again to repeat what I put out before, be aware that the COVID virus is thought to spread mainly from person-to-person, and especially between people who are in close contact with one another (within about 6 feet). COVID is transmitted through respiratory droplets produced when an infected person coughs or sneezes and these droplets land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Therefore: if you have any common flu symptoms — coughing, sneezing — please refrain from visiting InfoAge. It is an unnecessary risk, even if you are not presenting the additional COVID symptoms of fever, cough and shortness of breath. If you are coming to InfoAge make certain you observe the following guidelines are observed to insure your good health: 1. If you feel sick, stay home. Do not come to InfoAge. 2. If you do come, practice social distancing. If you are working alone, there is no problem. However, if you are working with someone else, keep at least 6’ apart and wear an N95 mask or another mask that protects your face. Remember, a mask pulled below your nose is of no help at all. 3. Remember to continue to always practice good hygiene: Wash your hands frequently, especially after touching any frequently used item or surface. Avoid touching your face. Sneeze or cough into a tissue or the inside of your elbow. Disinfect frequently used items and surfaces as much as possible. To learn more about the virus and what you can do to protect yourself and your family and friends, please visit the Centers for Disease Control website https://www.cdc.gov/coronavirus/2019-ncov/about/index.html.” Organizations – Please pass this email to all your members. Thank you and be safe. This will end!!

Re: [vcf-midatlantic] MITS Altair 8800 C&K switches

My apologies for all the fuss. Again: who knew this was difficult? > Jeff Galinat writes: > > According to Mike Douglas AKA deramp .. the American > Switch brand was used in the original Altair not C & K. > > S1 Toggle Switch On-None-On (Silver) APEM 5236AB > S10-S25 Toggle Switch On-None-On (Gold) APEM 5236CDB > S2-S9 Toggle Switch (On)-Off-(On) (Gold) APEM 5237CDB > > Take this as you wish but I do value Mike's opinion on this Um, I also saw this information 1) in the VCFed discussion list referenced earlier in this thread and 2) on notes it referenced on the deramp site, about a MITS Altair front-panel replica. But... But: those references to a replica, have confused me, as to whether the original Altair switches were of that brand; or if these identified switches are reasonable replacements; or if these are for the replica. Pardon my confusion. Also: in my most-prior post here, I acknowledge I *do not know* what brand was in-use. My error, to suggest C&K. That's why I'm asking. Again: proof beyond doubt, would be a photo of an original switch, in place, on an original front panel. Such a photo seems to be surprisingly hard to produce, hard to find. I certainly don't want to disassemble my MITS Altair just to take an internal photo. And my apologies, this is not a "personal trust" issue. I appreciate the identifications given, it's a "lead". My request for evidence is not unreasonable. I'm surprised it's so obscure! At least in year 2020. I've seen BUNCHES of photos of lots of MITS boards. But not of the original front panel, in profile. I'll be sure to provide those, should I tear my Altair apart. (No it's not for sale). Regards, Herb -- Herbert R.
