Hi After all the items I've bid on, I'd bid the same amount on a sealed bid as I'd snipe with. I've learned to look at an item and determine what I'll bid. I've learned to not change that amount, regardless of how the auction goes. Why should one let emotion rule their bid? If the item goes above my amount, I only watch the auction for interest. I've learned to never reassess my bid. I've found that after losing many bids, I'd rather lose to a sniped bid than to someone that pennies me up in open bidding. I realized that that person either doesn't know what he wants to pay or he may even be a shill bidder. It is the wrong place for either. Dwight

Supply and Demand (Was RE: Getting long; Was Re: eBay being sued. ..)

by Robert_Feldman＠jdedwards.com

While it is true that the ultimate numbers of an item are fixed, in this situation, it can be argued that the supply is not constant, since many the closeted items would likely have gone out in the Spring Cleaning trash. As long as there are only 3 of X for sale, then the demand will be high. The higher demand saves and brings out more items, the supply goes up, and the price (eventually, depending in part on the rate at which new supply appears) will go down. -----Original Message----- From: steve [mailto:gkicomputers@yahoo.com] Sent: Thursday, April 24, 2003 11:13 AM To: cctalk(a)classiccmp.org Subject: Re: Getting long; Was Re: eBay being sued over patent infringement <snip> People are digging stuff out of their closets that would of never been available for sale before, or available to only a very limited number of people. Many collectible items that were considered very rare before ebay, are now just considered common place, and prices have dropped greatly even though the actual supply has been constant. <snip>

eBay sniping

by mail.list＠analog-and-digital-solutions.com

Hello Mike, > But with sniping, people often bid a little higher just to protect their bid. That might be the case some of the time, but with extensions, a bidder has the opportunity to re-evaluate their decision, and go higher if they want to. With the snipe, you calculate what you think might do it, enter the bid, and then see how it ends ( for the seasoned bidder anyway ). > "I guess I got stuck. I was just trying to protect my bid." That "protecting the bid" strategy can backfire on the bidder just as you saw. > The people that whine the most about sniping, NEVER win auctions I hope you don't interpret my discussion as whining about sniping. I always snipe and usually win whenever I really want to. > The people that whine the most about sniping, NEVER win auctions, ... > they just NEVER bid high enough and would lose anyway. You're generally right. Most buyers that might whine about sniping are just expressing their disappointment that they couldn't buy the item as inexpensively as they had wished to. But from the sellers perspective, the exact ending time and the sniping would sometimes prevent their from being able to reach their best potential selling price.

by cb＠mythtech.net

>Starting it up is a bit of a problem, as I just have the system box -- no >monitor or software, and I shipped the RAM expansion card to TeoZ. You should still be able to boot it. There is a composite RCA output on the back. That will plug into anything that takes composite video (TV, VCR, game/tv adaptor box, whatever). It also uses a standard PC power cord. Plug those two things in, flip the switch, and you should get to the BIOS boot screen that will tell you the rom version. You won't get much further without software, drives, keyboard and anything else you might want to use... but at least you should get as far as knowing the ROM version. -chris <http://www.mythtech.net>

Source of Vintage CPUs: Vintage Burglar Alarms

by patrick＠evocative.com

Over the weekend I dissected two commercial alarm panels people had saved for me. While I was grateful for the thought, I didn't give my donors much credit for being discriminating. Boy was I wrong. When I opened the first panel, the board inside had a 6805 sitting smack in the middle of it. It also yielded a 2716, a 2764, a 6821, and a pair of 6116 static RAMs, along with numerous other Motorola-branded support chips and passives. I thought that was a pretty cool find, especially considering my short-sighted view of its potential. Panel #2, however, seems to have been the real gem. The large board within didn't look that interesting, just the usual myriad passives, and the panel was clearly very old (looked 20 years or more). It had a daughter board about six inches square and fully enclosed in shielding, hiding its contents. I removed the board, stripped it of its shielding, and found... an RCA CDP1806, two 1852s, an RCA-branded 6116, and three other support chips. The label on the 27128 EPROM on the board says "(C) 1984". Simple stuff, but I was jazzed. Classic computers are everywhere... --Patrick

286 Computers

by roger161uk＠yahoo.co.uk

Dear List, What is the concensus on disposal of 286 and 386sx hardware -- should they be consigned to the bin, or are there any folks out there collecting them? (or needing spares?). One is a Schneider 286 Tower PC (10Mhz), and the other is a Philips P3345 (16Mhz). Personally, I do not view either as being particularly noteworth (other than, perhaps, for sentimental reasons) .. but seems such a shame to turn them into landfill :-) Best regards, Roger For a better Internet experience http://www.yahoo.co.uk/btoffer

VAX 11/750 available in TX (?)

by gunther＠aurora.regenstrief.org

Hi, I was looking at a vendor site and it looks like they are offering an DEC 11/750 for $158.76. It's not quite clear, but since I don't have room for one I cannot simply order it. If you want it for the price, you can go on their web site to just order it and then call and ask them that you want to pick it up, that way you can find out what really they offer here and if it's not a real 11/750 system you can jump off (but if it is, you have a pretty good price.) regards, -Gunther

Well today's been interesting. There was snow on the ground this morning. At a Lotusshpere today I won a pair of tickets to the hockey game this Friday. And I just returned with an Arix 800, (quite large, hard drives have been pulled but the tape drive and cards are there), a Wyse 60 terminal, a box of unisys docs for u5000, a tape with PDN-5000, and windows 286 in the plastic wrap, a scanner new in box, and two clones that are missing the drives but still have the cpu's and ram. I was also offered a very old telephone switchboard this past weekend.

Kaypro Software-Micro Cornucopia Disks

by jforbes2＠mindspring.com

When I got several Kaypro II etc. machines several years ago at the thrift store, I also found a bunch of related floppy disks. Several of them are apparently copies of disks from Micro Cornucopia at Bend, Oregon (a mid 80s magazine?). They appear to have lots of useful software, I think public domain...assemblers, utilities, etc. I finally got round to getting 22disk running on an XT, and I've been reading these old floppies, and copying the contents to the hard drive on my main computer. No read errors yet, and I've done a dozen! amazing.... Is there any interest in this stuff, such as on a CP/M archive server somewhere? I should be able to zip it up and email or ftp it somewhere. I don't have room on my home page (url below). Here's a sample of what's in them, from part of the .doc file for one of the disks: ============================================= KAYPRO USER'S DISK #10-------Assembly Language Disk Micro Cornucopia PO BOX 223 Bend OR 97709 ----------------------------------------------------------------------------- CROWECPM.COM CROWECPM.DOC CROWECPM.Z80 This program is for all of you that wanted a Z80 assembler without spending hundreds of dollars for it. We modified the CROWE assembler so that it would work under any CP/M system. CROWECPM accepts standard Zilog mnemonics and creates a .HEX and .PRN files. The .HEX file is in Intel format and can be used to create a .COM file with the CP/M LOAD.COM. A symbol table is listed at the end of the .PRN file. It is a good assembler and the source code is included if any one would like to make it even better. See CROWECPM.DOC for information on using the CROWECPM assembler. ----------------------------------------------------------------------------- LASM.COM LASM.DOC This is another assembler. It is a rewrite of the standard CP/M ASM assembler. The difference is that this version can link assembly language programs together at assembly time. This version also runs faster the ASM.COM. This could be a the begininning of a linker for our Small C+. See LASM.DOC for details. ======================================================= Neat stuff, obviously. -- Jim Visit the Selectric Typewriter Museum! http://www.mindspring.com/~jforbes2

Odessey 1 (was Re: Fw: Game console up to $200)

by cb＠mythtech.net

>Magnavox didn't test market in that way, since there was no market to test >in. The Odyssey, being the first video game console, was sold alongside >every other Magnavox product just like any other television accessory >(which is what it was considered by many at the time, and why many people >wound up mistakingly thinking it would only work on Magnavox television >sets). Makes sense, but that doesn't preclude my theory from being correct. (see below) >My guess is your parent's could have gotten a used model, or you just >don't remember everything that actually came with it because you were so >young and it was so long ago. Nope, it might very well have been a test product. My father owns a market research company, and in the past Magnavox has been one of our clients. There is a good chance that it was obtained directly from Magnavox for the purpose of a focus group to discuss it and get opinions on it. Knowing that people thought it was only for Magnavox TVs just makes me believe this even more, as it would have been ripe for a focus group to try to figure out how to alter public perception. I also have 2 (3?) Atari 2600's that were never purchased, but instead left behind after studies and focus groups were done with them. I was supposed to have a Coleco Adam from the same way, but Coleco opted to take it back (which just made me want my friend's even more, which he shipped off to the Philipeans after telling me I could have it... so I think I am destined to never own an Adam). I tried to get a TurboExpress (the Turbo Graphix 16 portable unit). But at the time that I was playing with one when we were doing groups on them, it was one of 3 in the US >from Japan (the other two of them NEC execs were busy playing with in the same room) I had more toys growing up than I new what to do with... all because they would be left behind after studies, a practice that most companies seem to have stopped. Unfortantly, I didn't know the gold mine I was sitting on, so many of the items were broken and/or disposed of (much like how I cry when I see what Star Wars action figures go for today, and I think about how many I blew up with firecrackers in my back yard). Of course, NONE of this means that is how I got my Odessey for sure. It is just my suspicion based on what my parents were willing to buy. If it was remotely interesting or expensive, they wouldn't buy it. So all the best toys came from study leftovers. Since I remember the Odessey as being fun, and I'm sure it wasn't cheap, I have to assume we did a job on it and Magnavox left it behind. -chris <http://www.mythtech.net>

H89: Soft-sectored controller help/question

by patrick＠evocative.com

Thanks to Wayne Smith's timely docs for the Heath Z-89-37 soft-sectored floppy controller, after another person who shall for the moment remain nameless has failed to fulfill his (repeated) promise of spare parts and docs paid for seven months ago now, but I digress... I think I'm in the home stretch of getting the board installed and working. But... The installation instructions for the controller state that CPU board ICs U557 and U558 are to be removed, and a DIP header/ribbon cable from the controller board is to be connected into the now empty U557, and a "20 pin plug with jumper" are to be installed at U558. However, I do not _have_ the 20-pin plug with jumper that replaces the 74LS240 removed at U558, and the connection of a jumper in this socket is not immediately evident to me from studying the schematics. Can someone with an H/Z-90 and the soft-sectored controller please take a look and tell me what pins in the 20-pin plug at U558 are jumpered? Thanks! Patrick

Coming up dry for Alps/Radio Shack/Atari/Commodore plotter gears

by dwightk.elvey＠amd.com

Hi As long as the load is not that great, one can whack out the center with a drill and then notch it with a file. The drill needs to be larger than the OD of the inner splins. You then fill the voids with a mixture of epoxie and fiber glass wool. Using something like JB Weld will make the material as hard as most plastics. To keep things aligned while the epoxie is setting, make a jig to hold things by drilling some concentric holes in layers of plywood that are bolted together, for alignment. You need to put a wax surface on the plywood where the epoxie will be so it doesn't stick. It isn't real clean looking but should be functional.

Having worked out the pitch of the broken drive gears (120), and having looked on a couple of web sites _and_ contacted someone at Boston Gear, it's looking grim. According to the e-mail I got back, Boston Gear doesn't carry anything finer than a pitch of 64. When I asked who did carry such gears, the answer was: "I am not familiar with any company that makes miniature gearing." :-( My goal all along has been to find a company that has a bag of these on the shelf. I had no idea it was such an unusual item. I don't relish the idea of fabrication, but maybe that's what we're facing.

One other thought would be to make a mold with a good gear and use that to make new gears using something like JB Weld ( I do like this stuff ). You'd mold the gear on the shaft so that there would be no tendency to split the gear from pressing it together. The gear in the camera looked like it was a nylon gear and not the typical plastic. I didn't make a check on it though. Dwight

F/U HP 9134A HDD problem

by rhahm＠nycap.rr.com

Hello, I want to give some follow up on my problem interfacing a 9134A HDD to my HP 85. Nothing seemed to work and I was about to toss it when I decided to follow the advice of Alex Knight and vp**. Alex suggested removing the HDD and trying to initialize each one of the 4 logical drives with the HDD on it's side, "to loosen things up a bit". I took the top off, and hey, does HP use the biggest darn capacitors you have ever seen or what? There are two side by side capacitors in there that look like sticks of dynamite. Mindful of these I had the first screw holding the drive out when I noticed under a big dust ball that the ribbon cable connection from the HDD to the PCB was loose. I pushed it back on and to my delight everything now works fine! After a little detailing she looks and works great. Thanks again for your help. >I am having trouble interfacing an HP 9134 HDD to my HP 85.

KIM-1 question

by ssj152＠charter.net

I recently got a KIM-1 Rev. A (on eBay) and have a question about it. This particular model, the Revision A, doesn't say Commodore, and has a low (< 3000) serial number on it. What it DOES have, is a PIN 10 of U26 is cut in half, and a twisted pair of wires are attached 1) at the chip, and 2) at the board. The end of the wires not connected to U26 is not connected to anything other than each other. The schematic showing this component is in the KIM-1 User Manual, section 3.7 Is this part of a known mod for the KIM-1? It looks to me like it might have been used with a switch on the free end to select half duplex (open) and full duplex (closed) for the TTY interface. Your suggestions and comments are solicited.

HP storage formats on ss80 protocol disks

by peterbrown10＠hotmail.com

Hi Joe and Paxton?, Joe, I'm using device level calls to the NI GPIB board via the GPIB-32.DLL so any NI card that uses this driver should work - that includes NI ISA based cards (TNT-GPIB etc.), PCI cards (PCI-GPIB - the one that I'm using) and probably the PCMCIA-GPIB as well. For the record, my development machine is XP based though any Win32 operating system should be OK. I'm going to try to tidy the code up a little - if people think that the idea of making an online catalog of files is a good one then I have no problem with making this application available to help making it. Paxton, Apologies if Paxton is where you live and not your name - I live in the UK so my knowledge of US place names is a little lacking! My development machine has two GPIB cards in it both are PCI based - one is an NI PCI-GPIB card, the other an HP 82350 card. The NI configuration utility only displays the NI card that is installed in the machine however the HP utility shows both cards. It may be that the HP card can be controlled using the NI software but I haven't tried it yet - I'll have a play this evening. If the HP PCI based card can be recognised then it is possible that an HP ISA card would be OK. If not then it should be OK to use an NI ISA based GPIB card (around $20 on e-bay). I'll let you know how I get on.

FREE Some kind of SIMM card

by cb＠mythtech.net

I have some kind of 72 pin SIMM card here. I am pretty sure I pulled it >from a dying Zenith 386 before the PC was scrapped. The only label on it says JABIL APE 240-7929-20 I think it might be some kind of BIOS card, or Cache card. Silk screened between two chips says 32K Cache 85-3749-01. I don't know if that refers to the card, or just the two chips it is printed between. None of the other chips on the card have screened labels of value. If anyone wants it, send me your address, I'll stick it in a padded envelope and mail it out to you. -chris <http://www.mythtech.net>

Coming up dry for Alps/Radio Shack/Atari/Commodore plotter g ears

by Robert_Feldman＠jdedwards.com

Allied Devices (http://www.allieddevices.com/web2000/documents/pinhubgears.80.120.html) lists 120 pitch gears. Making a die (internal cuts) is probably harder than machining individual gears. -----Original Message----- From: Ethan Dicks [mailto:erd_6502@yahoo.com] Sent: Tuesday, April 22, 2003 10:13 AM To: cctalk(a)classiccmp.org Subject: Coming up dry for Alps/Radio Shack/Atari/Commodore plotter gears Having worked out the pitch of the broken drive gears (120), and having looked on a couple of web sites _and_ contacted someone at Boston Gear, it's looking grim. According to the e-mail I got back, Boston Gear doesn't carry anything finer than a pitch of 64. When I asked who did carry such gears, the answer was: "I am not familiar with any company that makes miniature gearing." :-( My goal all along has been to find a company that has a bag of these on the shelf. I had no idea it was such an unusual item. I don't relish the idea of fabrication, but maybe that's what we're facing. Rather than machining each gear, I wonder how hard it would be to make an extrusion die to pump out a long gear and cut it into 5/32" slices? -ethan The New Yahoo! Search - Faster. Easier.

PIP problem solved on Apple ][ CP/M

by vcf＠siconic.com

I was finally able to devote some time to my Apple CP/M issues and figured it out. It turns out that the version of MS CP/M that I'm using has got the device identifiers correct, even though Steve Hirsch warned that they were reversed in Microsoft's implementation. I apparently have a version where it is fixed. I first connected up my laptop to the Super Serial Card in slot #2 and then tried to PIP RDR:=B:file. I got a message to the effect that the RDR: device cannot be written to. Then I tried to get slick and use STAT to change the RDR: device to what PUN: was pointed to. That didn't work. Then I decided to just try PIPing to the PUN: device and it took, but I didn't see anything across the serial port. A little more digging and reading and I verified that, as Steve said, the Apple ][ CP/M standard is for a serial card in slot 2. In fact, the documentation I read indicated that the hardware configuration pretty much matches that of Apple Pascal. So I did a STAT DEV: to show me what devices were connected where. RDR: was set to PTR: and PUN: was set to :PTP (presumably Paper Tape Reader and Paper Tape Punch respectively). So then I did a STAT VAL: to see what the possible connections were for each device. PUN: could be TTY: PTP: UP1: UP2: I thought for a second and then figured it would be worth a try to see if UP2: stood for the device in slot 2. Sure enough it did, and when I tried a PIP to PUN: it worked. So I was able to PIP the files directly from disk over the serial port to my laptop. Very convenient. There apparently is a utility that allows you to copy files from CP/M disks to Apple DOS disks but it must have come on a DOS utility disk that I just don't have. I'm sure KERMIT or some sort of X-modem protocol was written that would have made this a lot easier, but I seem to have misplaced my Apple CP/M disks. Oh well. At least I know how it's done, and this can serve as quick docs for someone attempting to do the same in the future. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Odessey 1 (was Re: Fw: Game console up to $200)

by cb＠mythtech.net

>I've had one these since I was a kid, but I've never seen the rifle >or the boxed games before. I've never seen boxed games, but then A: I was pretty young when I used to play with mine, (and I believe it predates me in existance), and B: I have a feeling mine was never obtained via the market, but rather as a test item directly from Magnavox, so it may never have been complete with market packaging (I know I have a white labeled box that the system and controllers and stuff goes in, I'm assuming that was standard packaging). As for the rifle. I don't remember everything it was used for, but I know I LOVED the haunted house game that used it. There was a haunted house overlay, and basically "ghosts" appeared at various windows and doors and you had to shoot them. (IIRC, the ghosts were nothing more than white blocks, but hey, for early 70's that kicked ass!) -chris <http://www.mythtech.net>

TrantorMini SCSI Epp

by xdale＠yahoo.com

Hi Fred: You Wrote:Trantor was bought out by Adaptec. You might try them. There were three models that I'm aware of: T338 (rectangular thin box) that hangs off of the parallel port, or screw it on so that it gets enough leverage to break the connector. The black labelled earlier sub-model is significantly less reliablke than the later blue labelled one. Also marketed briefly through NEC (they once had the drivers on the web) T348 cable based model. T358 cable based model with ECP/EPP support NONE of them are very reliable; but it's a handy way to hook things up to laptops, etc that don't have provision for a "real" SCSI controller. Would you like me to snail mail a copy of the disk? Or would you prefer e-mail attachment? COULD YOU KINDLY SEND ME THAT DRIVER AS AN ATTACHMENT IN REPLYIN TO THIS EMAIL?

LOL! > It sure would make sorting drives easier than > trying them out on an old peecee! (Which actually > needs to be done anyways, to test for > functionality.) A rule of thumb I use, but I won't swear is universal... Is the LED color. USUALLY... Red LED signifies 360k/180k Drives, and a Green LED signifies 1.2mb Drives. And I also think that as for IBM Drives, the 360k at one point were made with and Asterisk molded into the front case. I could have this reverse. But, I seem to remember some discussion (perhaps here) that someone thought it was odd that IBM would start adding the asterisk to 360k Drives, hence having some with and some without, rather than just making all 1.2mb drives with asterisks. I may have this one reversed though. But, I've used the LED color as a good indicator for years. Also, if you look at the jumpers on the logic board, near the drive select jumpers... A 1.2mb drive should have a Speed Select Jumper (SS) to select High speed Data Transfer to work on AT-Standard Floppy Controllers, and low speed (for what? I don't know... Maybe to work on an 8in Drive Controller?) So, that's another indication of whether the drive is high or low density. Regards, Al Hartman The New Yahoo! Search - Faster. Easier.

need CP/M boot disks

by xtguy＠mindspring.com

I was told that Don Maslin can help me with boot disks for some old CP/M computers. I need boot disks for the following: Morrow Micro Decision MD 1 Epson QX-10 several different Kaypro models I tried to make a boot disk for the Morrow using 22disk and the 'STDCPM22' file at 'www.retroarchive.org'. 22disk did not have a file format for the Morrow MD 1, so I used the format for the Morrow MD 2. (As far as I have been able to find out, the MD1 had full height floppy disk drives and the MD2 had half-height drives, but they were the same capacity). When I tried to use the floppy to boot the computer, it would spin for about 15 seconds, then the computer would reboot. I was making the boot disk on a computer which had a 360K floppy drive.

Compaq EISA Netflex-2 ENET/TR adapter?

by rschaefe＠gcfn.org

Well, in the Big Box of Token-Ring Stuff I received a few days ago, there was one EISA TR adapter, a Compaq Netflex-2 ENET/TR. ENET as in Ethernet, TR as in token-ring. That's right, this baby apparently can speak ethernet *and* token-ring! I've been going over Comp^H^H^HHPs site for the last half-hour, and the only thing I've found out about it is that a part number is COMX142151, the TR side is an option that I presubably have installed (as the card has a jumper block on the TR side and not the ENET side), and it was avaliable on just about everything from the pro-whatever-500 through the -4500. Does anyone know where I can find the .cfg file for this? Can it speak ethernet and token-ring at the same time? Is there a manual for it anywhere? Thanks! Bob

cctech digest, Vol 1 #476 - 3 msgs

by musicman＠satcom.whit.org

I had an accident involving 2 liters of coke and two dozen of my prize 5 1/4" floppies. I carefully slit the top (away from the access hole) and rinsed them in a sink of dishwater, then rinsed and let dry completely, then slit new disks, remove the new media disk and put the old (now cleaned) media into the new sleeve, and taped it with clear tape. Then immediately copied the disks to good new disks...They worked like a champ and I recovered everything....

Well, dunno if this will be helpful to you or not, but we had a zillion 3.5" floppies from 1984 (first Mac) and they got immersed in water during Hurricane Andrew in 1992...they didn't work at all, so figuring we had nothing to lose, I slit the labels, popped 'em apart, and removed the disk itself, wiped down both surfaces with Q-tips and rubbing alcohol. Then I took new floppies and disassembled them, tossed the blank media, and put the old disk inside the case...taped back together, and almost all of them worked well enough to recover the data. The real issue seemed to be that the two paper pads swelled and wrinkled, then dried, depositing lint on the disk surface and impeding spin. The disks themselves seemed to weather the water fine. (The Mac itself survived Andrew also -- I still have it. Only hurricane damage was a couple dead keyswitches on the keyboard, I replaced those and all's well -- 11 years later. :) If only the roof had been so durable...)

>A Magnavox Odyssey from 1972 is up to $200 with a few hours left to bid. I >would like to have one but not at these prices. I have one of these, but not complete. Its missing most of the little stuff like chips, cards, cash. Some overlays are missing, and I am pretty sure the rifle is long since destroyed. I'm also not positive if the unit itself works or not.

Howdy...new to list and a couple questions.

by mike＠shawnuff.net

Hey there! I hope this isn't bad form but I'm new to the list and just wanted to put my collecting needs out there and ask a question or two. Currently I'm partial to anything TRS-80, PCjr, or PC XT related. But I'm also trying to fill in some gaps with Commodore , TI 99, and Apple II(e). Also, where do y'all find most of your stuff? There's always ebay, but that's usually at a premium. I've thought about notifying some of the local auction houses to keep an eye out. Any input would be appreciated, and it's good to know that there are folks out there who don't immediately think "samford and son" whenever they see "obsolete" hardware! -Mike

PDP-11 Freeware CDs for RSX-11 and RT-11 (Originally Produced by Tim Shoppa)

by jhfinepw4z＠compsys.to

The last two times I posted this, another person contacted me either for help or to request the CDs. This will be the last time for about 6 months unless more people reply. In regard to the Freeware CDs for RSX-11 and RT-11 that Tim Shoppa originally produced: I am in the middle of finishing a second (very small) batch of CDs and could easily add a few additional copies. I will be making all copies of the CD images from: ftp://ftp.trailing-edge.com/pub/cd-images/ http://www.classiccmp.org/PDP-11/RT-11/ http://www.classiccmp.org/PDP-11/RSX-11/ Since not everyone has both a high speed internet connection and a CD burner, I thought it would be helpful to make them available. If you have both requirements and are using Windows 98 SE / Nero Burning, I can help with the details if you don't know how to burn a CD from an "Image File". I have even been able to produce a label for each CD that is close to the original label from Tim Shoppa, although since they were scanned (THANK YOU FOR THE HELP), they are not perfect. They are available at $ 5 / $ 9 / $ 12 for 1 / 2 / 3 CDs. In addition, I understand that Memorex Black CD-Rs have a longer shelf life and are available at Business Depot. If anyone wants those instead, add $ 1 for each CD that you are requesting. Thus those amounts are $ 6 / $ 11 / $ 15 Please contact me directly for my snail mail address. I picked up some Memorex Black CD-R blanks and started on the copies for those who have already requested that a Black CD-R be used. Please include your mailing address!!!!!!!!!!!!!!!!!!! In general, I will regard any funds you send as a gift so that if anyone really can't afford the CDs, please state why that is so. Outside of the US, probably about $ 2 should be sufficient for extra postage. All amounts are in US dollars. Please ask if you are not in the US. No point in converting twice. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

FS/A: Northern Telecom (NT) DisplayPhone Plus NT6K90AC

by big_boy_toddy＠yahoo.com

I have for sale a few Northern Telecom (yes, NT, not Nortel) Model NT6K90AC Displayphone, Date of Mfr. Nov 15 1984 (yeps, that makes them almost 19 years old, way ahead of their time). If you are interested, and know what this is for, do let me know. I think 50 USD for each is fairly reasonable. They are in very, very good working condition taken out of service a number of years ago, stored and finally sold off recently. I picked them up at a government auction, and they are being sold as-is. I know little to nothing about them, and am by no means an expert, you are more than I am...PS. I hope this is ok to offer these here for sale. I looked at the listing, and it seems this kind of device was WAY ahead of its time, so much so that NT didn't do much with them, but they are prized for collectors. I hope I can find a nice home for them.Best wishesTodd Nathan The New Yahoo! Search - Faster. Easier. Bingo.

Seeking good home(s) for old hardware [UK]

by Paul.HILLS＠landisgyr.com

I would love to take the SWTP6809 system. I already have an SWTP6800 that I acquired recently. Getting on 20 years ago I built a 6809 based computer from a series running in the UK magazine "Electronics & Computing Monthly", called the 77/68 system. This was based on the SWTP stuff but was marketed through a company called Stirling Microsystems in Baker Street, London. Does anyone else here remember that system? There's one reference to it on a Google search here: http://www.jakelod.demon.co.uk/7768.htm, although now even that link isn't working anymore. Was I the only person ever to build it?!!! I never got it working, and I think my parents must have chucked it all out unfortunately, although I've still got all the docs including circuit diagram and hex dumps. paul -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]On Behalf Of Brian Chase Sent: 16 April 2003 21:20 To: Classic Computers Subject: Fwd: Seeking good home(s) for old hardware [UK] Here's something of possible interest to rightpondians. -brian. ---------- Forwarded message ---------- Date: Wed, 16 Apr 2003 10:23:51 +0000 >From: John Carlyle-Clarke <john.cc(a)nospam.europlacer.co.uk> Newsgroups: alt.folklore.computers Subject: Seeking good home(s) for old hardware Can anyone provide any suggestions, flippant or otherwise, as to where I might seek new homes for some old kit that has been cluttering my attic for many years?

They do use HP 88140 tapes (and may take 3M DC6xxHC tapes too). I don't think you can easily use the 791x/4x standalone disk->tape backups to restore the image to another model of drive. For that matter, I'm not sure what the drive writes on them in the course of a standalone backup or whether the drive will permit user-level read access to the standalone backup media. I don't see any reason why it wouldn't, except for notions about security, but then I'm pretty sure these drives will write to some regions of the tape even if you've set the write-protect knob to "protect" -- so I think they're too smart for their own good. -Frank McConnell

message from comp.sys.cdc

by aek＠spies.com

Just saw this on comp.sys.cdc Unfortunately, they may have waited too long for help :-< Greetings: Our computer museum, The Cybertheque Museum, has been preserving important CDC computers and their software, manuals and spare parts since 1971; we are currently in a major funding crisis and there is jeopardy of the irretrievable loss (lien sale) of the following machines (and more): 1. CDC 160 S/N 18 (handwired at Chippewa, overhanging desktop, rising punch) 2. CDC 160A S/N 270 3. CDC 606A S/N 9 (non-corporate switches) 4. CDC 8092 Teleprogrammer S/N 24 5. Librascope General Precision LGP-30 vacuum tube computer S/N 254 6. Various IBM card unit record peripherals for the 160. 7. CDC 1604 Console (with typewriter and punch) 8. CDC 3200 Console and Typewriter Console and various 3200 frames. 9. CDC 6400 cabinet 10. large amount of 1604, 3000, 6000, 7000, Control Corp, DDI, and peripheral logic cards 11. The entire FOCUS program library for the 160/160A 12. Much of the software library for the 1604 13. Much object and source for 6000 SCOPE 14. Experimental Operating Systems from Roseville and Rochester for the 160A/8090 15. 1700 Software 16. The entire software library for the Roseville TFC/MTC 32bit mini- computer. And much much more. Since a crisis precipitated by the unreasonable real-estate tax and redevelopment policies of Anoka County, MN in 1991, we were denied our musuem building and forced to store the above systems in storage unit warehousing in the Twin Cities area. The rental agreement was reasonable at the time but in the ensuing years the warehouse company decided to breach the agreement and forced us to pay ever increasing rent until it has become a major burden. The intent was to ready new facilities in Northern Minnesota and move the collection; the high rent at the warehouses and the high cost of transportation has delayed the relocation effort. We must pay $900.00 per month for the storage; we are attempting to raise money to cover some past rent to avoid a lien sale on April 23. We are open to discussions to salvage the collection before the sale and/or to partner with others and receive donations to support the ongoing rental until relocation is possible. Please help us avoid the sad loss of such important artifacts. Michael Grigoni founder and president Cybertheque Museum

Cranking up a HP 7914.

At the urging on one of the other local collectors and against my better judgement, I went back and picked up the HP 7914 disk drive that was part of the HP 1000 system that I recently acquired. I think this is going to be a waste of time since I've never found one of these old drives that still worked. But I'm going to try this one and see what happens. Anyone have any suggestions about anything that I should check or do before I try to spin this drive up? Joe

DEC RRD40 CD caddies (was Re: DEC newbie)

I managed to obtain > some caddies for my RRD40, so I think I've been rather lucky. > I remember reading not too long ago that the things seemed to > be made of unobtanium. I recall back in the 1990-91 timeframe when VMS was first being distributed on CD as well as tape, we got these plastic cases that held the CDs, and each CD was in an RRD40 pincer caddy. Which was fine for my lab because we actually had an RRD40 on hand... I'm not sure if the CONDIST started early enough to be delivered the same way. I used to have one of these VMS 5.x CD kits around here, but it seems determined to remain hidden so I can't confirm. --S.

PlusTek Spectra 1200 and 6000 scanners

by cb＠mythtech.net

Anyone know if the interface card for the PlusTek Spectra 1200 and 6000 sheet feed scanners is a SCSI card? I have both of these scanners. On the back is a DB25 Male port. No power input, so it pulls power from the connector. The manuals I have just indicate that it uses an "Interface Card" that comes with the scanner. Naturally I don't have the card or the cable. I'm curious if it is a SCSI card as many older scanners used. I'm looking to possibly bring one back to life to try using for archiving of old manuals (the HP All-In-One I had set aside for the purpose I just found out is a Print/Copy/Fax, no scanner). If it uses a special custom card, either A: does anyone have one that they want to give me (and the cable if it is something special as well), or B: does anyone want the scanners? I don't know if either works as they were given to me as is years ago and have never been used. I do have the manuals for them, as well as one driver disk (but the drivers appear to still be downloadable from PlusTek's web site). -chris <http://www.mythtech.net>

DEC newbie (was need caddy for RRD-42DA CD-ROM drive)

by healyzh＠aracnet.com

> > Just checking since I've seen others slip before ... > > > > The RRD42 takes the standard "flip-top" caddy that > > must have been made in their millions. > > Well, that's a relief. Can you point me to a source for these common caddies? Try places that carry old PC junk. This type of CD-ROM was used primarily in 1-4x CD-ROM's that were seen in PC's (the fastest I've seen is an 8x that I put in my PDP-11/73). Of course you can also find this style CD-ROM in DEC, Sun, and probably other manufacturer's equipment (I think Apple had one drive of this style). Actually your best place to look might be eBay, I'd imagine they're pretty easy to find there. Just be glad you don't have one of the drives that use the 'pincer' caddies! Zane

Last call for Printronix

by cb＠mythtech.net

Last call if anyone wants my Printronix or parts from it. The printer supposedly has a fried transformer in the power supply. I know it does not power up. I have the complete printer, rolling stand, and at least one paper basket. Its located in NJ (07450), I'm not willing to ship the whole thing, but I am willing to hold on to it for a pickup, or to strip any wanted parts >from it and ship those. It goes in the dumpster Monday afternoon if someone doesn't speak up first. -chris <http://www.mythtech.net>

5.25" drive identification

by cb＠mythtech.net

>Machines with 1.2M drives weigh less than machines with 360K drives? No, no that doesn't work... my Leading Edge machines have 360K drives, and they weigh less than my IBM AT's with 1.2M drives. :-) -chris <http://www.mythtech.net>

5.25" drive identification

by dlormand＠aztecfreenet.org

I have been told (by an IT professional, take that for what it's worth) that 5.25" 360K drives have the latch handle on the left side of the drive, and the 1.2M drives have it on the right side. All the drives I have in view right now, this is true. Anybody have a notion of whether this is absolutely true in fact? It sure would make sorting drives easier than trying them out on an old peecee! (Which actually needs to be done anyways, to test for functionality.)

Was HP 7914 - Priam 15050 & 3350s

by Innfogra＠aol.com

Actually IIRC the HP 7914 has a Priam 15050 single platter(?) hard drive with a 14 inch platter. The HP 7912 used the similar Priam 6650 drive. These were used in many early computers from the late 70s to early 80s. Early Xerox 8010 Stars had them so there may be some info on the drives on Al Kossow's Site. IIRC these auto head park (with a loud clunk) when powered off. There may be drive &/or head locks too. I am looking for information on starting up some Priam 3350s, 8 inch HD drives. I have an Intel 330 (6 slot Multibus 1) and an Intel 380 (14 Slot Multibus 1 with separate drive cabinet) that I want to fire up before I part with them. Both these use Priam 3350s. Also looking for ideas on how to start them safely. Last time I used them was about 1989. I did park the heads and locked the drives for the intervening years. Paxton Astoria, OR

Need command codes for Epson Stylus Color 600

by vcf＠siconic.com

Does anyone have documentation for the complete command codes of the Epson Stylus Color 600 printer? The command codes are apparently identical to those of the LQ-850, so a manual for that printer will also do. Any help would be greatly appreciated. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
