All, I just finished reading these posts, and watching the accompanying YouTube videos, and I was absolutely blown away: http://eab.abime.net/showthread.php?t=79346 Amazing work, and really neat to see someone doing such a modern reconstruction of core. Definitely worth a look. - Alex

Core memory
by william degnan 27 Nov '15

Getting intermittent stuck bits with my pdp 11 non parity core stack. Without getting into a lot of detail, I noticed that something is causing the inhibit to fart high every so often, effecting address bits and to a lesser extent data bits. I have been doing a lot of research. My question.. aside from manuals and the tech docs does anyone have any anecdotal info, advice or test procedures related to DEC core RAM and intermittent stuck bits? Shielding tips?

I remember ~10 or so people got nice cheap mostly working Heathkit 3400's at VCF 10 last year. Anyone do anything with theirs? Someone today sent me a question through my web site about terminal settings for the 3400 monitor program, I pulled my 3400 system out and fired it up to test and confirm mine is 2400 7/n/2 -- Bill

Manuals For Sale or trade or for the V.C.F.

Just found several more boxes of manuals. Specifically, I found about 300 pounds of old TRS-80 model II, 12, 16, and 6000 manuals (both hardware and software). I have most of them. Looking for a loving home. Lots of Xenix, programming, database, and OS manuals as well as hardware reference manuals. I want these to find a home, not the recycle bin. The "federation" has first dibs if they want them for a donation. Any interest? Make an offer direct to my email. Two manuals I found that I've been looking for for several years are the Informix for Xenix and the VideoTex and Office System server manual. Not software yet, but I'm just getting started.

We give you a letter describing your donation. You and your tax advisor have to figure out what it's worth and what it does to your taxes. corey cohen uǝɥoɔ ʎǝɹoɔ > On Nov 23, 2015, at 4:29 PM, Bill Sudbrink via vcf-midatlantic <vcf-midatlantic(a)lists.vintagecomputerfederation.org> wrote: > > Evan Koblentz wrote: >> It's certainly interesting, but we do not purchase artifacts. > > Yes, but you give generous tax breaks.
