My Biggest GRIPE, period...

by philclayton＠mindspring.com

>> I respectfully request that the parties discussing Ebay in gory detail >> please spare us all and take it to E-mail. >> >> Sheesh... > >I second that motion! > >Steve Robertson - <steverob(a)hotoffice.com> For what its worth I think most discussions on the forum will naturally end when everyone is tired of the subject, and not when one or two individuals say it should stop. I think "My Biggest GRIPE" was a good topic since most of us trade on eBay, I think it was an important discussion. I know the subject has been on this forum many times before, but there are new users here and I am sure they learned many things from the discussion on the In's and Out's of eBay trading.. Personally I don't read discussions on PDP-8's or Vax's, Have never even seen one, and likely never will.. My interest is mainly Pre-DOS Micro computers. To be honest about 50% of all that's discussed here is not in my main interest, but I have no right to tell anyone here not to talk about the subject.. So if you need to turn on your "eBay" filter, I will just turn on my PDP-8 filter, mine is called "Press the delete key" it only takes 1/2 a second.. Phil..

>4) If it has non-DEC stuff in it (like the memory is all 3rd party non-DEC >MOS RAM) then that would negatively affect the price. Some of the most valuable/useful stuff you might find in a PDP-(anything) can be the non-DEC stuff.

OSI C4P-MF board (was Re: Tandon TM 100 5 1/4" drives)

Preventing cartridge tape stickiness

by rdd＠smarty.smart.net

Can anyone provide any information about the best way to preserve cartridge tapes, such as DC300 tapes, so that parts of the tape don't stick together? Using new 3M DC300 tape several years ago, onto which I'd copied the source code to the S.6 version of the Accent operating system, the tape stuck together about two years later and was destroyed when I tried to read it. Not sure how to try to preserve the rest of the data, written with the Stut (the streaming tape utilitu software) software, that's still on the tape - any ideas? -- R. D. Davis rdd(a)perqlogic.com Be careful what you wish for --- you http://www.perqlogic.com/rdd may get your wish ...and it might not Tel: (410) 744-4900 be what you were expecting.

My guess would be a TU56 (DECTape) drive rather than TS03, but again, we're just guessing :-). Reminds me of the apocryphal story of the old lady who's son died in a hunting accident. She calls up a local car dealer, and asks how much her son's car might be worth. Dealer asks her what the car is, and she replies "a '67 Chevy". The dealer says that such an old car probably isn't worth much more than $100 on today's market, so she puts an ad in the paper and sells the car right away, for $100. Of course, the buyer was very happy with his purchase, for it turned out this '67 Chevy was a finely-preserved Corvette Stingray! -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Approaching Scrappers

by jeff.kaneko＠juno.com

Randy: Approach these guys as often as possible, because timing is everything. The one I deal with here locally, doesn't care a whole lot about 'collectability' (which is actually a blessing, because I can get stuff so cheaply). As a result, if you're not there before it gets torn down (or rained upon, as applicable), you're out of luck. I recently missed a VAX 6000 this way. Never saw the machine; just the (broken) bits in the bin when 'Axel' was done with it. I recently uncovered a bin filled with HP 98xx's (sorry Joe). It was obvious they had been under water for a *LONG* time. Heartbreaking. I've told them time and again that they should give me a call when new material arrives with the d|i|g|i|t|a|l or hp logo on them, but to no avail. They have bigger fish to fry (like aircraft fuselage assembly jigs, for example). Anyways, all I can offer you is to be vigilant, and poll the yard frequently. They recently chopped up a NOVA IV-- all I got was the 8" FDD's. Sigh.

Approaching Scrappers

by edick＠idcomm.com

A couple of relatively important things to keep in mind: (1) scrappers sell the items they collect as scrap. Homogeneity is important to this pursuit, i.e. unpainted pure aluminum scrap is more valuable than mixtures of painted and unpainted aluminum, and there must be no non-metal or non-aluminum mixed in, else the value goes WAY down. This means that they have to add labor to the mix before they can scrap most computer components, e.g. disk drives. (2) they are ALREADY in business and ALREADY plan to make money with what is in their lot. They already know what they will get for their stuff once it's "cleaned" and sorted. That often means they have to add considerable amounts of labor in order to get top prices. (3) they already know that there is some stuff that YOU will pay for if you think it's going to be of value. Some people will pay more for old stuff than others, though and they know it is out there, though they don't know what YOU specifically want. If you treat them as though they know their business, and as though you know yours, i.e. with appropriate respect, even though you may not believe either to be true, a simple question at the outset about how he wishes to set prices on the type of materials you wish to take home is probably all you need to get started. Many yards have these prices posted somewhere, so look around and read the signs before you start asking questions. It might not hurt to start with a "look around" the yard. If you see others collecting what you think might be of interest to you, then watch and listen. You'll be surprised what you can learn!

Vax 4000-305A - what is it?

by Philip.Belben＠powertech.co.uk

A couple of weeks ago, I was told that a vax was to be thrown out at work. I assumed it was the rather nice pair of Vax 9000 machines that was our main server for many years, but alas no. It is a Vax 4000-305A (with some well cool disk and tape accessories) It is a desktop box but lives in a DEC 3/4-height 19-inch rack that used to house a machine called SF200. Another shelf in the rack houses a fun-looking tape drive of which I can't remember the number, and two SCSI boxes (the sort that take about 8 drives in one box) are standing on the floor of the rack. Anyway, what sort of machine is the 4000-305A? AFAIK it was running VMS when last it was running... (The other question is... Where do I put it??? With luck, I may have rented somewhere suitable within the next couple of weeks, but I don't know. And then there's the SGI monitor I got given today. Aargh!)

Wanted: MOSTEK 387x Manual

by bill_r＠inetnebr.com

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.

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

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

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

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.

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.

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...

EBaying; howling after an auction

Bidding up the $X + n cents edge? <<< BIGGER GRIN >>>! > >Have fun with it, from one who varies his $X + n cents and keeps it a >secret ;-), Chris >-- -- > >Christian Fandt, I agree with having fun on eBay, it is a lot of fun sometimes.. Also have had a lot of fun seeing how close I can get to the end of the auction, like kicking in my maxim bid at exactly 5 seconds remaining.. Depending on the traffic load on eBay server at the time, I have scored a bid (Victory) with only 1 second remaining.. (Can you heard the crowds cheer). Sometimes I have also lost this way because the server on eBay was running slow and I got the very unpleasant notice that "The bidding is now closed on this item" << GRIN >>.. Seriously though if you see something you really want I suggest not to bid on it till the last 15 seconds, then place your maximum bid. Bidding early will only drive the price higher.. In a way all auctions on eBay are sealed bids simply because you do not know what someone else will bid in the last few seconds.. And in that respect its kinda fun.. So I say if you want to play the eBay game, better play the same way others do.. So have fun... Phil..

OT: Not-classic Hardware Freebie

by af-list＠wfi-inc.com

I've got the mainboard and cpu card from an AST Manhattan P5090 server (dual Pentium-90 sockets) that are marked "non-working" with no further details. IIRC, we pulled this from service a couple of years ago and it didn't want to post when we tried to test it sometime after that. If someone wants this, let me know. Otherwise it finds it's way to the round file...

Frustration..and part of the RT11 System Manual is Online

The perfect end to today... Somehow, I've lost my backup to the image files of an RT11 System Manual. Ugh.

Wanted: Mac 128K/512K schematics and service manuals

by jlewczyk＠his.com

I've recently acquired one 128K and one 512K Macintosh and am looking for technical documentation on it (schematics, logic diagrams of pc boards). I thought that it would be easy to find on the web, but I've had no luck after more than a week of searching. Any help with schematics or service manuals would be appreciated. I've found some pdf files that have some rudimentary diagnostic procedures: "if the logic board is bad, replace it" "if the floppy drive is bad, replace it". The 128K's floppy isn't working, even after cleaning the coagulated lubricant and I am trying to diagnose the problem. Thanks! John jlewczyk(a)his.com

EBaying; howling after an auction

by fpp＠concentric.net

There are a few eBay tricks. Bidding you maximum by $X + 1 cent or = 51 cents etc. Most people bid in even dollar amounts. Adding 1 penny to your maximum bid often gets you the item. A lot of people know this so now they add 51 cents. It has worked for me several times.

Hard vs soft is a controller issue, not a drive issue (at least for non-customized drives like those found in the Commodore 4040, et al.) The drive has to have a sensor for the index hole. The Tandom TM-100 series does.

That would be the case. It is the exact model used in the first IBM PCs and XTs. My Kaypro II has a pair of TM-100-1As. -ethan ===== Infinet has been sold. The domain is going away in February.

Zenith Terminals

by dlw＠trailingedge.com

I picked up a couple of Zenith Data Systems Terminals this weekend. I can't find any indication of a model number anywhere on them. They look sort of like the Heath H-89 system (I think that's the one) but without the built in disk drive. Any one tell me what model this is?

I got these for cheap, and am passing that on to whomever may be interested. Email me if you are interested in these before they go to eBay.... Joe

My Biggest eBay gripe..

by jpl15＠netcom.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**. 'Normal' auctions close when **no further bids are recieved** in an agreed-upon span. I have bought and sold hundreds of thousands of dollars' worth of aerospace and industrial surplus at auctions large and small, sealed-bid and open-floor, honestly run and 'otherwise'. The reason I dislike the eBay model is that the item most often goes to the fastest/luckiest bidder (sniper)... and that's totally wacked, IMHO. I am not going to join the "capitalism vs. overvaluation" debate. I'm a captialist *and* a collector... that's internal conflict enough. I wonder how much tweaking would be involved on the part of eBay's logicians to convert it over to the more familiar "going, going, gone!" type of format. What do You All think?? Cheers John

More early -11 stuff unearthed

by ethan_dicks＠yahoo.com

As the weekend progressed, I kept digging. Under a PDP-8/L I found an MM-11 box with five MM-11 backplanes (for the 4K sets), a peripheral backplane (KM-11?) a PSU, several UNIBUS jumpers, missing only the fans and bracket. Presumably now, I could assemble several MM11 sets and test them from some other PDP-11, say an 11/34, which happens to be nearby. Hopefully, additional digging will uncover the 11/20 cpu chassis. I did locate the box with the CPU boards and all the core drivers. The box had apparently gotten wet and some of the cut leads on the back of the board have rusted a little. I'll need to figure out how to get that stuff off before I power anything up. Another gem I thought I'd lost was my TVT-6 - a T.V. Typewriter I bought and assembled as a kid with lots of intentions of doing something interesting with it. I never even applied power. Looking back on the shape that board is in, I must say that I've gotten *much* better at soldering. :-) Perhaps I'll attach it to my SYM-1. -ethan ===== Infinet has been sold.

My Biggest eBay gripe..

by edick＠idcomm.com

The eBay folks are making money, and that's what they set out to do. It's to their advantage to get the highest bids because they get a cut. Sealed bids don't necessarily get that, because, though they tap into the insecurity a bidder may have about what an item will bring, they don't tap into the last-minute feeding frenzy which often drives prices up. If you set up your bid so you enter your highest bid right away, but let the system make minimum incremental bids automatically each time someone overbids you, that's essentially the best of both worlds for the buyer. He can pay less than, but not more than, what is essentially a sealed bid. He is allowed to continue bidding after his maximum is reached, but the system won't do it automatically.

Programming the Z-80

by edick＠idcomm.com

The various CP/M resources out there not only have Z-80 code and development resources, but 8080 and 8085 code as well. Be careful you don't try to run some 8085 code. Most of the code is 8080, since that's the common denominator, but many of these sites even have 8085-family support and the housekeeping isn't always perfect. The Rodnay Zaks book is one of a few Z-80 books written just for Z-80 coding. It was a disappointment to me, but it is not half bad. Check your local library. They often have these things sitting on the shelves in considerable (unused) quantity.
