FS: Vintage 24 Bit Pattern Generators

I've got three of these for sale: http://www.ebay.com/itm/272038025877 Zero information on them, they're just a RC oscillator driving a bunch of CMOS counters. Copyright date of 1985. They're powered from a single 3V lithium cell, which is included. Verified operation with my oscilloscope. These were probably intended to produce stable patterns for students familiarizing themselves with logic analyzers and/or oscilloscopes. Thanks, Jonathan

Wow! Impressive list support
by Evan Koblentz 06 Nov '15

At my request, Jason H. sent our group's list research to the provider support people. They said there is one IP per server, and there's one U.S. server, so that issue is moot. Jason also told them: ------------------------------ We were seeing inconsistent spam flagging from some providers, the biggest of which was Google. We noticed that in some cases, incoming mail from www.mailmanlists.us to Google's SMTP servers were failing SPF validation. Looking into the headers of said messages showed two different scenarios. One where SMTP communication occurred over ipv4, which was fine. And one where it occurred over ipv6 which resulted in the following header: Received-SPF: softfail (google.com: domain of transitioning vcf-midatlantic-bounces(a)lists.vintagecomputerfederation.org does not designate 2604:3400:dc1:43:216:3eff:fe36:d305 as permitted sender) client-ip=2604:3400:dc1:43:216:3eff:fe36:d305; Adding your ipv6 address (2604:3400:dc1:43:216:3eff:fe36:d305) to our SPF record has cleared up the random spam flagging issue, but does raise a couple of other issues. Many times reverse lookups are used to help identify spam, since you don't have an AAAA record defined for www.mailmanlists.us, nor a reverse ptr record, this may cause an issue for some clients. Though we've not witnessed any adverse behavior attributable to this, it is something to keep in mind. A few suggestions on how to fix the issue for all your customers who may unknowingly be experiencing issues: 1) Either kill ipv6 on your host (which is probably not the right way forward given the way things are moving). or 2) Get your ipv6 entries setup, and have your clients add analogous ipv6 entries for their lists DNS and SPF records. Honestly, don't feel bad about this, I think google made some change a couple weeks ago and I was caught flat-footed on this with my own mail server when everyone suddenly started talking ipv6 to each other. ------------------------------ List support guy wrote back: "We'll follow your suggestions and get them done this afternoon." ------------------------------ That is amazing. - Evan

Possible spam fix: DNS change
by Evan Koblentz 05 Nov '15

05 Nov '15

Yesterday's messages about our headers + spam made me realize we were on to something. I called Jason H. and he determined that the txt record in our DNS settings -- the GoDaddy registrar side, not the mailing list side -- needed to have an IPv6 entry (vs only an IPv4) to properly synchronize. We made that change. Jason will explain it better than I could. If it seems to be fixed then we'll inform the list company.

Everyone, Here are some very important updates. Vintage Computer Federation, a 501(c)3 federal non-profit, is documented by the IRS at http://tinyurl.com/pmvrur7. We are working on expanding our presence in popular sites such as GuideStar, Charity Navigator, and wherever it seems appropriate. Our fiscal year ends June 30. At that time, we'll make a public financial report as required by federal law. However, with the calendar year ending in less than two months, now is an excellent time for everyone to consider donating to us! You'll receive a form to complete. You keep a copy, give another to us, and the third to your tax preparer. Where would your donation go? Lots of places. It costs money to (for example) build our new museum exhibits, conduct 'rescues' of vintage computers, host the Vintage Computer Festival East, bring our exhibits to other events, get supplies for workshops and Festivus, keep the storage warehouse organized, maintain our (coming soon!) new web site, pay various accountant/legal fees, buy insurance, market ourselves, and grow a capital fund for future projects. There are two ways to donate. Traditionalists can send a check to: Vintage Computer Federation, P.O. Box 417, Eatontown, NJ, 07724. PayPal fans should use the email address donations(a)vintagecomputerfederation.org. (There will also be a button on the new web site, but that probably won't be ready for a while.)

Semi-OT: Old Test Equipment
by Systems Glitch 05 Nov '15

Fired up my GenRad 1217-B Pulse Generator, which is mostly tubes (I think there's transistors in there somewhere, haven't had it apart in a long time), and set the pulse width to 1 mS: http://imgur.com/X1KwZ8e Automeasure on the Tek 2432A says 1.04 mS, not bad! Especially since 1 mS is the range select, and the actual width is set with a vernier dial! Unfortunately it's probably worth more for the tubes than as a pulse generator, nowadays. Thanks, Jonathan
