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.

>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

Tonights pickings,

by kenziem＠sympatico.ca

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. Regards, Stuart Johnson

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>

Quadram "Golden Quadboard"

Hello - I got your email address from a websearch - you seen to know about the Quadram Quadboard. I have a "Golden Quadboard", what the difference is between this and the regular variety - I don't know. However, I'd really like to be able to use the real time clock, is there a setclock program, and a readclock that sets the DOS clock from the board at bootup? Do you have any idea where I could get programs like these? Any help would be appreciated! Thanx! -Zorba

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?

5.25" drive identification

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.
