I [don't] hate E-Bay (was Cromemco 68000 on ebay)

by Watzman＠neo.rr.com

E-Bay now requires buyers to accept Pay-Pal, and forbids them from advertising that they will take any other form of payment. So I if you look at one of my auctions, it says Pay-Pal and doesn't list any other form of payment. BUT .... that doesn't mean that a buyer won't take another form of payment, indeed, if a customer asks me if I will take a money order .... of course I will, I don't have to pay the Pay-Pal fees if he sends a money order. And almost every other E-Bay seller will do the same. [it's "dicier" if you want to send a personal check, for obvious reasons] I'd like to see someone challenge their policies on this on anti-trust grounds (for those of you who don't know this, E-Bay owns Pay-Pal], but so far it hasn't happened. If you have your own private credit card account with a bank and can take credit cards DIRECTLY, they will allow you to do that (and advertise it) instead of Pay-Pal.

Looking for internals docs for an IBM 7861-015 modem

by ethan.dicks＠gmail.com

Hi, All, Going through a pile of stuff in the basement, I uncovered a hamfest find from a couple of years back - a short stack of frontpanels for an IBM leased-line modem. I picked them up because they have a 4x5 keypad with the keys marked 0-F (and a row of blanks). That alone made them worth it, but having looked at them in detail, it might be fun to adapt them as is rather than part them out. Cursory examination reveals o a 16x1 VDF display with "british flag" segments o the aforementioned 4x5 keypad o several DIP parts that may be equivalent to ULN2803s that seem to drive the VFD segments o some sort of TI-branded 40-pin DIP microcontroller o a 34-pin pigtail cable to the modem Since most of the cable pins are clearly grounds and Vcc, there appears to only be about 12-14 non-power signals which disappear into the microcontroller and the (I think) transistor arrays. What I'm hoping to find is any sort of documentation that might reveal to me how the modem MPU drives the front panel. I don't have the modem, so I can't scope the signals. I can produce a reverse-engineered schematic from the real board up to a point, but a mysterious MCU is difficult to scope out. Worst case, these were worth the $1 I paid for them just for the parts. Best case, I can stick some sort of MCU on the 34-pin connector and talk to that from a "real" computer. Second best case, I could dike out the TI MCU and wire something in its place. So... google did not reveal any obvlous locations. Does anyone know of any secret repository of IBM hardware docs? Thanks, -ethan

anyone know how to run maindec-11 papertapes?

by brad＠heeltoe.com

Does anyone know how to run maindec-11 diagnostic paper tapes? Say I wanted to run maindec-11-dfkaa-b1-pb which is an 11/34 cpu test. I know I could run xxdp, but if I had no disk and I wanted to run the test from paper tape, what's the procedure? Naturally I'd like to try it on simh first... Is there a manual for the maindec diags anywhere on line? thanks, -brad

looking for a good HP to industry std. part number list.

by g-wright＠att.net

I'm been working on a HP 3000-37 and I can't find a list that gives the ROM size or industry std. numbering for the ROMs. These have the HP # 1818-3449. I would also like to find some tech. manuals for the same, but I'm probably dreaming again Thanks, Jerry Jerry Wright g-wright at att.net

CC list archives?

by sellam＠vintagetech.com

Is the CC list still active? If so, does anyone know what happened to the archives? They are currently 404. I sent an e-mail to Jay, but as usual he did not respond. I'll probably get a response in 6 months. This is not meant as a slam against Jay since I'm much worse :( Anyway, just checking, since my only conduit to CC is through the archives. In fact, I won't know if anyone responds to this inquiry since I have delivery set to off. If anyone knows anything and wouldn't mind shooting me a private message I would appreciate that greatly. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

I [don't] hate E-Bay (was Cromemco 68000 on ebay)

by chrism3667＠yahoo.com

the internet could have *brought* us any number of things. One party organized and brought us eBay. For the most part it's a racket. Sure someone low on cash can get more money for an item then they otherwise would have dreamed of (can you say vintage computer?). But there methods of dealing with issues is atrocious, for instance this recent piece of debauchery (see I'm becoming incoherent) where a seller is prevented from reporting truthful feedback about an atrocious bidder. It is, of course, the seller's fault when people refuse to read through a listing, then refuse to pay, THEN get to leave you negative feedback. ?My rating is about 71 I think. But I've participated in HUNDREDS of transactions. The reason my score is so low - I utterly REFUSE to play the one hand washes the other game. I think I left negative feedback once (really really wanted to another time, but couldn't). I guess though that that particular debacle isn't ePay's fault (coercion). ?I'll utilize from time to time, but personally I'd cackle w/laughter if their stock values suddenly plummeted. And this is coming from a rather unapologetic conservative Republican (for the most part). All brokers will have their part in the lake that burneth w/fire and w/brimstone. --- On Sun, 3/29/09, Barry Watzman <Watzman at neo.rr.com> wrote: From: Barry Watzman <Watzman at neo.rr.com> Subject: I [don't] hate E-Bay (was Cromemco 68000 on ebay) To: cctech at classiccmp.org Date: Sunday, March 29, 2009, 2:36 PM I am a "Power Seller" with over 10 years on E-Bay, probably 5,000 transactions, but I am not a business and most of my activity is buying, not selling. First, re: "I hate [ebay] because it defrauded me in 2005", that is, in all probability, BS.? E-Bay didn't defraud you, the other party (buyer or seller) did.? E-Bay is not a principal to the transaction; it is merely a venue for bringing buyers and sellers together. Second, IF YOU KNOW HOW TO USE E-BAY, it is EXTREMELY safe.? Most of the sellers (and buyers) are honest, more than 99% I'd say.? If you pay through Pay-Pal with a credit card, you have about 3 levels of protection even if the seller is fraudulent:? E-Bay, Pay-Pal and your credit card company.? You do have to know how to use the various systems to protect yourself; you can look at a seller's history, and about the comments that people who have dealt with that seller previously have left about their transactions.? If you educate yourself about how to use E-Bay, it is quite safe.? Is it perfectly, totally safe?? No, of course not (neither is any other marketplace), and getting issues resolved when they do occur can be a hassle and can take months and require that you be persistent and well organized. There are a surprising number of people with an aversion to E-Bay.? That's their loss, because it's one of the greatest things that the Internet has brought us, both as buyers and as sellers.
