Actually, in the category of data that I have easy, web-based access to, I'm finding that I'm having the best luck with patent searches. As I find interesting ones, I'll post the links. I plan to put them all at scribd.com to provide one-stop (free) shopping. To start, here's the link to the 207 page ENIAC patent: http://www.scribd.com/doc/4960983/ENIAC-Patent-US3120606 If anyone knows of patents likely to have good tube or relay logic circuit descriptions within them, please give me the patent numbers and I'll post the patents as PDFs on scribd.

It is discourteous and disrupting to other members of the community who might be trying to follow the original subject. How would you feel if you had started a new subject only to later see the discussion taken in a different, unrelated direction. -Mardy

ACCRC blog: It Ain't Dead Yet

by pdp11＠saccade.com

The ACCRC (Alameda County Computer Resource Center) has started a blog showcasing some of the more unusual equipment they get turned in for recycling: http://deadmeatmarketing.blogspot.com/ The about column says "Anyone with ideas about how to put this stuff to good use please leave a comment." My brief perusal turned up a Wang 600, a wire(!) audio recorder, and an WWII O-Scope. Actually, I think I still have a scope just like that at my Mom's house.... Cheers, jp http://www.saccade.com

Free stuff!

by derschjo＠msu.edu

Well, now that the mailing list is back up I can list some stuff I need to get rid of :). Local pick-up in the Seattle area, only -- please. (Most of this stuff would be so expensive to ship it wouldn't be worth it anyway...) I'm willing to drive a bit to meet someone halfway if necessary. - IBM PS/2 model 25. In good shape but does not power up. Color screen, some manner of hard disk installed. - TRS-80 Model 12. Kind of rough, but with a little work it'll clean up. Runs, but power supply needs some work (was running fine while I was testing it but a cap let out the "magic smoke" and I haven't had a chance to recap it.). Has card cage expansion but no cards. Dual 8" floppy. - 5 boxes of TRS-80 Model II/12/16/6000 documentation. I bit off more than I could chew when I took this in, I hope someone can use this... all manner of manuals, if you're interested I can give you a list. - A Wang word processing terminal (I can't seem to find a model # on it). Heaviest terminal in the world. Powers up and beeps but that's about all I can get it to do. - Cipher M995S 9-track drive. Works. 1600 & 6250bpi, SCSI interface. Desktop enclosure. Heavy :). Josh

Terak 8510 system on eBay (# 300248208909)

by classiccmp＠crash.com

It's listed for $199 plus shipping for the main unit, an 8512 additional 8" floppy, and an 8532-1 monitor. Includes keyboard, some floppies, and some manuals. It's been discussed here before, but in brief: Significant LSI-11 based system with bitmapped graphics, perhaps best known for it's use as a platform for the UCSD p-System. No connection to the seller. Was tempted, but can't really justify it given some other upcoming expenses. But they sound like pretty neat systems to mess about with... See http://www.threedee.com/jcm/terak/ for details and other links. --S.

PDP 11/45 multi processor systems

by jim＠g1jbg.co.uk

Hi all, whilst reading my 11/45 processor manual the other night, I came across the statement that, if Unibus A and B are separated, Unibus B can be used for inter-processor links, so long as one of the connected devices is a Unibus controller. Does anyone have any experience of this configuration, and if so, what operating system was used. Finally, is there any reason why I couldn't link the Unibus in my 11/44 to Unibus B in my 11/45, assuming I had some software that could take advantage of it. Jim.

First Northern Germany DECnet Party

by hoelscher-kirchbrak＠freenet.de

First Northern Germany DECnet Party, who wants to join? Who wants to install, configure, network, cluster or program ALPHAs, MIPSen, VAXen and PDPs just for fun together with 10 to 20 other DEC enthusiasts for a day or two? We want to join everything running on DEC hardware or talking DECnet, including simulators (e.g. simh). Beginners are welcome! Everyone brings along his computers and together we will build something really nice! Maybe there will even be some VAXstations to lend for the event. If there are enough persons willing to participate I will arrange a large room and other things needed ... Beside the activities mentioned above there are further things planned: - Barbecue - Hardware/Software/Manuals Swap - Talk, Discussions, Helping each other, ... A possible date would be the weekend 18./19.10.08. The location will be in the "Weserbergland" a little south of the town of Hameln. Details will follow when I know more! Please let me know if you would like to come! Ulli The VAXorcist P.S. I really do not know how many persons might be interested, but as a precaution I want you to know that I will limit the number of participants to a maximum of 20.

OT: PC keyboards

by jules.richardson99＠gmail.com

Hey all, I'm soliciting ideas for a (full-size) PC keyboard to go with my laptop (which one of the dogs saw fit to trample) - which unfortunately means it has to be USB (spit!) I don't want to spend an utter fortune (it's just a keyboard, after all), but nor do I want some sort of "dead flesh" monstrosity (which seems to be *everything* I've tried in real stores so far). I used to find the old PC XT keyboards a little too 'clicky', but on the other hand everything I've tried since seems a bit too spongy. Maybe someone does a USB to PC-AT or PS/2 converter unit, which would allow me to connect an older keyboard? Ideally I really don't want 'Windows' keys or other stupid extra keys (email / web etc., or all the other crud modern manufacturers seem to like including) - I'll take them if I have to (and if I can them pull them out and fill in the holes, even better :) Any recommendations from the list? (off-list if needed; I don't want to jam the list with modern PC chat!) cheers Jules
