HP vintage boards being sold as scrap

Where are you, relative to the seller? I can see a problem though. Isn't it impossible to have ebay-won items shipped to other than one's ebay-verified address? I'm not sure... I know to get things sent to my reshipper, I have to have them set as my 'real address' before bidding. That's why I asked if anyone is close enough to pick up the boards. Not to mention sidestepping the seller's problematical packing intentions.

NOS old media and other stuff available

by sales＠elecplus.com

Send him an email, and he can send you a list. He is NOT interested in selling 1 or 2 boxes of floppies. He needs volume deals. I have a list of items available from a Value Added Reseller that closed several years ago and had these items in storage. All items are OEM, NOS and include LOTS of data media spanning generations (Round Reel data tapes, 4mm Cassette tapes, ????? Tape Cartridges, 35???, 5.25??? and 8??? Diskettes), Trillium and EnGenius phone equipment, various electronics components and packaging materials. Have images of many of the items available.

DEC RP04 service manual available

by jnc＠mercury.lcs.mit.edu

> From: Evan Koblentz > I know of two RP04 drives in the wild. One belongs to a private > collector. VCF has the other. Right, but does VCF need it scanned? Oh, one other place that might have one: the MIT MC KL10 had a couple of RP04's; when it was taken away to Scandanavia, they might have gone with it. I think that machine is now at LCM? Noel

Cleaning an old keyboard

by jnc＠mercury.lcs.mit.edu

> From: Al Kossow >> This is documented in NASA's official history of Project Mercury, for >> which it was invented. > could you post a pointer to the document where this appears? If the reference is to: Lloyd S. Swenson, James M. Grimwood, Charles C. Alexander; "This New Ocean: A History of Project Mercury"; SP-4201; NASA; Washington; 1966 "WD-40" does not appear in the index. There's another less likely book ("Project Mercury: A Chronology", or something like that), but I can't be bothered to drag it out and look, because I'm pretty sure that's incorrect. My understanding is that WD-40 was invented to protect the stainless steel skin of the Atlas ICBM (which was often left un-painted), built by Convair. I do recall seeing this in one of my Atlas books, which is alas currently not shelved, and I don't have time to find it. FWIW, Wikipedia agrees. The rest of that post (about how it's a waxy material in a solvent) is I think correct; it certainly agrees with its original intended usage (above). Noel

DJ11 Maintenance Manual available

by jnc＠mercury.lcs.mit.edu

> From: Pierre Gebhardt > there seems to be a copy of the maintenance manual in the unibus-folder > on bitsavers: EK-DJ11-MM-003_DJ11_Maint_Man_Aug76.pdf Argh! I looked in that folder, but didn't see it! (And Manx says its not online, either.) > Would be worth checking the document revision. Mine's earlier: DEC-11-HDJAA-B-D. > What is missing, however, is an engineering manual with the schematics. Well, the M7820's will be the same as in the DH11. The M7285 and M7279 are DJ11-specific, though. I was going to say that 'does anyone even have any DJ11's any more, to need the drawings' (they're like lobotomized DZ11's - the serial line config is done with jumpers!), but on looking it turns out the RICM probably has some in their -11/45's.

Cleaning an old keyboard

by trash80＠internode.on.net

I resurrected an old keyboard and mouse I like. Not wishing to gross anyone out but it looks like over time there was a build-up of oil etc from my hands etc and over time being stored away its turned to a really almost hard paste like stuff on both the mouse and keyboard. I've tried number of agents to clean it off but limited success. Any tips please. Kevin Parker

simh, professional 350, 380

by emu＠e-bbes.com

Hi all, I saw an old version from 2006 as "xhomer" which emulates the professional 350. Was there anywhere a version, which emulates the 380? Cheers

Vintage computer store hints in Minneapolis?

by jplist2008＠kiwigeek.com

Morning all; I was up in Minneapolis over the weekend and will probably be back next weekend - I was wondering where the local geeks might go for some nifty goodness (for sale or just to gander at)? When I was up there I hit FreeGeek and picked up a SCSI SyQuest EZ135 external drive and a couple of carts. I also rolled through The Ax-Man... for 3 hours because I'd never even heard of the place before and was absolutely astonished at what I'd found. (If you've never been, you _must_ go) But I thought I'd poll and see what else might be found up there? I'm mostly a non-PC collector (Sun/SGI/Digital/+ random things) - but easily amused. Speaking of, there's a set of power supply modules for a PDP at The Ax-Man on University. There were several h744s and 745s and and an h754, although one of them someone has started to pry apart and the Molex (?) connector is broken from the PCB, although the pins were still attached to the board. They were asking $9.95 for each and I wasn't willing to buy and hope they worked. Cheers; - JP
