I'm looking for a Mostek 3870 Databook from 1981 (I've got an older one; for that matter I've got the 1981 version too, but it ended up getting peed on by rodents in the basement of my old house while we were moving... *sigh I hope that wasn't some kind of mouse social comment; they didn't touch the Zilog Z-80 manual or the Intel 8086 book right next to it.) I've got a bunch of the 3874's & 3876's with EPROM sockets on the back; we've used several in personal projects. That book was extremely useful, but now it's not something I want to get close to; it's sealed in a plastic bag in case we come up with a way to deodorize it but... *thud. Any help would be appreciated! :-) (Wonder what happens if you bake a book in a kiln or something at 250-300 degrees for a few hours? Would that take the smell out? It's not sticky - just *stinky*.) -Bill Richman (bill_r(a)inetnebr.com) http://incolor.inetnebr.com/bill_r - Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.

Tandon TM 100 5 1/4" drives

by edick＠idcomm.com

I've got a -4A with a sticker on the door latch which says 96tpi. Do these also come in 100?

Outbid

by rkaplan＠accsys-corp.com

Hello all - About a week ago I put a bid on a Micro PDP-11/23 on ebay. I was top bidder until the end. Of course the end was when I was asleep (3 AM) this morning (serves me right for sleeping). Got up and was very disappointed. Since the recent discussion about collectors vs. enthusiasts I thought I would share this with the group. As a new collector, I have been reading alot about sources and establishing networks but they are not in place yet so one of my main venues is ebay at this time. I plan to start contacting scrappers, universities, and friends in companies soon. But, alas, today a PDP-11/23 flew by. Randy Kaplan

I EBay snipered these PDP extenders last night. Did anyone else see them?

by daniel＠internet.look.ca

I got two quad (looks to be originals for the 11) PDP extender cards for $21.50! I had to get up at 1 in the morning to nail it. If the spacing is the same on either side of the middle "slot" then I guess I just have to cut them down the middle for the PDP 8? Sorry "flipchip". http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=179610883 The guy had it listed under "Photo Electronics" with no PDP nor Digital in the subject/description. john -----Original Message----- From: Aaron Christopher Finney <af-list(a)wfi-inc.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Monday, October 18, 1999 3:03 AM Subject: Re: EBaying; howling after an auction > > >On Mon, 18 Oct 1999, Dave McGuire wrote: > >> >Sniping is the art of ignorance on the value of something. >> >> Huh?

Oz auction site & wanted list.

by black＠gco.apana.org.au

There ain't a great deal there, but Oz users can go to an Aust. auction site at www.sold.com.au I managed to pick up a PET 8032 plus dual drive for $27 & a whole heap (read - boxes full) of C64 equipment & software. With a bit of luck, more will become available. Now for the wanted list (preferably Oz, but will consider o/s if required): Commodore Plus4's, C16's & VIC20's plus s/ware, carts, manuals etc. C64's & 128's plus peripherals, software & manuals. Oz only (because of weight): Any type of PET plus peripherals (working or not). And I'm not likely to get either of these, but it's worth a try - a KIM-1 (possible) & a C65 (buckleys chance) // Lance Lyon black(a)gco.apana.org.au llyon(a)primus.com.au Ph: +61-3-6254-7376 Mob: 0416-012-331 //

Dec ID questions

by Innfogra＠aol.com

I am interested in finding out what some of these DEC products are and what systems they work on. Console panel KY11C M7228 KW11P RTclock M8265 CPU? M8266 CPU? M8090 ICS Controller? M6850 W7430 A005 Relays A007 Relays More of this batch are coming in. Also these, prob. OT due to age, but I am still curious. DEC 400X with RF31s & a TF 85. What size are the RF 31s & the tape. What systems does the 400X plug into. It looks like it has both SCSI I & SCSI II ports. DEC BA 350-KB case SCSI II BA 35X Power Module BA 35X-VA Power Supply TZ 87-VA Tape Drive No hard drives only the tape drive plugged in. I have another that is the same except the tape drive is a TX 87n-VA. What is the significats of the "n"? What is a DEC Infoserver 150? Thanks for the help. Paxton

Macintosh Hardware Question

by af-list＠wfi-inc.com

Hello, Mac gurus... Can someone tell me whether the IIsi PDS slot is compatible with the PDS slot on the IIfx? I know that the PDS slot in general is fairly different between models, and the IIfx is fairly unique in a hardware context anyway. What I want to do is use a PDS-based video card in a IIfx, and it's a working pull from a IIsi... Barring that, does anyone know if there was ever a 3rd party video card for the PDS slot that is compatible with the IIfx? Cheers, Aaron

VaxStation Questions

Mr. Pietkiewicz: > 1) The output from a >>> sh mem command is: > 01000000 > 00000000 > 00FE3E00:00FFFFFF > What does this translate to??? I'd say 16MB (1000000 hexadecimal). > 2) What monitor would I need / be able to use with this box? I'm using > VT320 for a console now, but the thought of an OpenVMSWindows box has > potential.... Assuming the (cheaper) GPX graphics, 1024x864, 60Hz vertical (?), one DEC monitor is the (19-inch) VR299. A Web search on that should provide more details. If you got the (deluxe) SPX graphics, then it's 1280x1024, 67Hz vertical (?). I'm using an HP 98754A on my AlphaStation, and I'd bet that it'd work with an SPX card in the VAXstation, too. You could steal the keyboard from your VT320 (or a VT220, and probably others). The mouse (DECburger) is a VSXXX-AA, and it's pretty DEC-specific. > 3) When I try to boot from the external RZ55 I got with it, VMS 5.5.2 > comes up and hangs (solid) after displaying: > %TMSCPLOAD-I-LOADTMSCP, loading the TMSCP tape server > This happens even trying to boot to VMS's single user mode, and > with or without a TK50Z attached... What's "VMS's single user mode"? Whether the tape drive is connected should not affect this, agreeing with your observation. I suspect that it is trying to form or join a cluster, and, as its old cluster pals are all missing, it's unable to get a quorum. You need to do a conversational boot, and set the SYSGEN parameters VOTES and EXPECTED_VOTES both to 1 (so it won't expect to find anyone else), or else VAXCLUSTER to 0, so it won't do any cluster stuff. The procedure's probably in the FAQ, ""ftp://ftp.digital.com/pub/DEC/dec-faq/vms"", but something like the following might be close: >>> B/1 [device, if necessary] SYSBOOT> SHOW VOTES \ SYSBOOT> SHOW EXPECTED_VOTES /[If you're curious.] SYSBOOT> SET VOTES 1 SYSBOOT> SET EXPECTED_VOTES 1 SYSBOOT> WRITE CURRENT SYSBOOT> CONTINUE [Begin hoping here.] ------------------------------------------------------------------------ Steven M.

My Biggest eBay gripe..

by mbg＠world.std.com

> My main concern with the eBay auction algorithm is that it is >time-limited, rather than bid-limited.... the aution closes after a >fixed span **no matter what the bidding activity is**. I have to agree (to a limited degree). The problem is that how do you decide on how long to extend it. If you are trying to help those people who might be asleep when their 'high bid' is topped, you have to remember that no matter when the auction ends, *someone* who might want it may be asleep. I'll admit to sniping and being sniped (sometimes I even send mail off to the winner saying something like 'Well sniped... :-)' ) The reason sniping is done is to get a bid in such that the others bidding don't have a chance to get in another bid. If the auction was extended by as litle as five minutes beyond the last top bid, you wouldn't stop sniping, but you would prevent people from playing the game just mentioned... there would always (so long as you were at a terminal) be time to bid again. But then you have the problem of being able to ensure, within some timeframe, the end of the auction. Also, it means they have to keep it on the books for longer...
