Since there have been many people asking about Sellam's posts: In the past he was a very active poster, and he has the collection and documents to be able to give very detailed answers. If I recall correctly, the major reason that he withdrew from the list was because he became a father and had very little spare time. Perhaps when his children require less time he'll come back. This is not to be read as an endorsement of his post, writing style, hairdo, or method of eating asparagus- just as an answer to the Sellam FAQ.

It is unfortunately a fact of life that stuff will sell better on Ebay. It is also a *very* unfortunate fact of life that I either need to buy this house or move. VCM will not provide enough money to do that, and the reality is that Ebay will. But I still try and list somewhat uncommon items on VCM that are unlikely to generate ebay bids. > As for Sellam, > > I've never met the guy. I've heard a lot. :-) What I like about Sellam and a lot of other people here is that they *DO* rather than just talk. VCF started out as a thought here, but he was the one that took it and ran with it to create VCF. And ditto for Jay when ClassicCmp needed a new site. Jay didn't just say woe is us, but took the ball and ran. And with his hosting other classic computer related websites, all I can say is that I greatly respect the man ... and I've never met him :). And look at Al with what he has done with Bitsavers, and Erik, and Curt, and ... The amount of knowledge available on this listserver and what is being done is truly incredible. I've met quite a few people on this listserver, and at times it is fun to just talk and listen. It would be nice if everyone would just get along and not jump on every annoyance that comes along.

Scrap equipment and fraud (was Re: Digital archaeology of the microcomputer, 1974-1994)

I did not witness this, but I heard at a DECUS that some time in the late 1980s, DEC had a different kind of scrap problem - they would scrap numerous things at the factory, load them into bins and sell them to gold scrappers. The problem came with a gold scrapper started selling bits and pieces (like MicroVAX CPU and memory boards) to other parties which would end up in the 3rd-party resale stream and end up in customers' hands. The damage was two-fold... 1) reputation, and 2) the IRS discovering that "scrapped" items were being bought and sold. The solution, I heard, was to get a chipper that could reduce boards, racks, etc., into postage-stamp-sized chunks before handing the waste over to the salvage companies. I understand that the first guys to get a bin of metal and PCB chips rather than boards and boxes they could cherry pick, were a bit surprised. OTOH, one of my co-workers from Software Results took a pile of boards >from the scrap bin and drilled and mounted them to make a 1.5m-tall PCB Xmas tree (the solder mask was green). The bean counters were initially upset until the drilled holes were pointed out to them - clearly the boards had been damaged sufficiently that nobody was going to be mistaking them for usable product. -ethan

Ebay idiocy

If he'd just reminded us that VCM was there and asked us for more support, fine; I'd probably have clicked on it right away and bookmarked it. As it was, however, I found his message quite offensive, FWIW. I assumed that his comment about the IPO was meant tongue-in-cheek (as he pointed out to me in a similarly "directly" worded, ("F"'ing) off-list reply), but I suspect that if he really did give eBay a run for its money and someone offered him a bag full of money (not so ridiculous these days), he just might say yes. Nevertheless, if he were truly as altruistic as you say, why is he ranting at us so forcefully for, essentially, not generating enough traffic for him to be able to justify charging for his service? I imagine that Jay and the moderators donate far more time gratis running this list than VCM demands of Sellam... Not that I see anything wrong with it, but perhaps it is relevant that he does make money from renting out equipment, sourcing obscure items, etc. I doubt that he will be able to address the stuff we grudgingly like about eBay: the wider selection of available items (and price range) for buyers, and the vastly larger number of potential buyers for the sellers; blaming us for that is pretty silly. Maybe good will isn't worth what it once was, but I don't think ranting at and offending potential customers has quite made it on the list of successful business tactics yet. m

Short answer: No. ;-) Heck, you can't get schematics, technical information, or anything on most newer hardware now, so one would need to reverse-engineer almost everything; and the tools that do evolve that are necessary to work on even today's stuff (fast oscilloscopes, etc.) are priced out of the hobbyist's pocketbook. Not to mention: Back in the day, there might've been more computer companies with more "different" computers and OSs back then, but at least each computer was "standardized" to a point. All CoCos ran a 6809, all Commies, Apples & 8-bit Ataris ran 6502s (or derivatives ;-)... Now, you get 10 people with PCs with an Asus motherboard, and you'll have 10 different motherboards, with 3 different CPUs, 2 different types of RAM, and gawd-knows-what for peripherals and interfaces. Even tho the OSs and whatnot are standardized, the underlying hardware is completely different >from machine to machine. >Am I the only optimist on this list? Cripes... I like to be an optimist, but I tend to be a *realist* and IMHO, realistically, today's PCs aren't "hobbyist quality..." read: with no available schematics, very little available information, expensive tools necessary for board/component rework, and whatnot, that to me anyway, it would be very hard to consider today's hardware platforms a good basis for a hobby[1]. Now software & whatnot, sure... Anywho, that's just IMHO and all that.

When I was at Lucent in Columbus, they started drilling through the HDAs of discarded drives, not to protect against data theft from a working drive, but against employee harvesting of the scrap bins. Saw a lot of things there I wish I could have saved, including a 3 cu ft box loaded with PDP-11 core memory, and other DEC items from the 1970s and 1980s. I would have happily have paid many times the gold scrap value of the boards, but, for obvious bean counter reasons, no mechanism exists for that. -ethan ---------------------------------------------------- There is another reason for this. Warranty fraud has become a 7 digit problem for most OEM manufacturers. Get a good stock of scrap products, take parts off a good product, replace them with the bad parts and send the good product in for repair. Whether very little effort, you can amass a huge stock of good parts and sell or assemble them in units for resale. There are even places on the internet where you can get labels made, or do it yourself. The best way to discourage this type of fraud is to physically damage the parts so they can't be reused. At Philips, we specified a hydraulic punch through the PCBA and the Optical Pick Up unit. But by time this was implemented, Philips had lost several million dollars to the fraudsters. So most OEM companies have explicit protocol for scrap destruction. There are just too many people out there trying to make a buck out of it. Billy

Early Unix micros; AT&T 3B5

by cclist＠sydex.com

This mention of the Lisa, M20, Onyx, etc. running some flavor of Unix around 1982-84 and my memories of the Hated Plexus reminds me of an experience that I had about that time (i.e. right about the time of the Ma Bell breakup). I'd read in one of the trade rags about the AT&T 3B5 and thought it would make a great development machine. To this day, I don't know if my hunch was right or not. I called AT&T computer sales and got the runaround for at least a week. Fortunately, most of the referrals I was given were 800 toll-free ones. I never could find someone who could sell me one. It seems that everyone thought I was talking about the 6300. It was very frustrating--"We have dollars; we like trade them for computer. Don't want 6300; want 3B5. Ugh" Did anyone on this list ever succeed in acquiring one around that time? If so, how was the service and performance? Cheers, Chuck

If so, how was the service and performance? AT&T carpet bombed Georgia Tech with 3B stuff around the time I got there (1985). There were at least 2 3B20s (rebadged control processor for a 5ESS) brutally overloaded with freshmen writing Pascal programs, lots of 3B2 + AT&T 5620s and as I recall at least one 3B5. Compared to the Sun gear I got to use at the time (3/160 & 3/50), they were slooooow, but built to last. Seriously physically over-engineered.

After developing for Lisa we continued to use the Lisas as hosts to develop software for the Mac using a serial cable to send the software and to run the debugger on the Lisa screen and the target software on the Mac. I think at first we had Lisas with twiggy drives so we could not write Mac discs on the Lisa, but maybe I've got it wrong again. I do know that Apple loaned us a Mac with a 5 1/4 inch slot in it for a twiggy drive, though there was a 3 1/2 inch installed in it. That would probably be worth something now. Back to the crashes, I remember they really made you jump out of your chair, the screen went haywire and the horrible sound it made like hitting bone with a coarse circular saw. Though the Lisa was black and white, the phosphor must have been made of a mixture of two, as you could get a purple effect if you crash made the screen flash at a particular frequency, and on another time it seemed to make one flash of pale green, though maybe thats the 'Pink Elephant' effect. Even with only square wave output you can make more than beeps, my old mainframe built in 1962 can play crude music. Not that Handel and Bach wrote crude music, it was the rendition which was crude. > > Nothing is available to the OS to derange the CRT scanning.

Yes thats all the system routines allow anyway, I just checked (on Lisa). As both 128k Macs and Lisa had a single built in CRT I can't see why the refresh rates would have been programmable, but thats just how it appeared. The only other option I can think of is we had somehow managed to do something which had affected the power supply rails, but the machines rebooted OK so there was no permanent damage. Could switching the position of the framebuffer between frames full of ones and ones full of zeroes cause this perhaps? I remember you could get the spark gap capacitors to fire on old monitors on the Apple ][ when you rapidly changed the screen image.

The Lisa Pascal compiler had an option for "automatic stack expansion". IIRC, this was off when compiling for Mac and on when compiling for Lisa. Each routine started with something like LINK A6,#constant where the constant was the space for the local variables and maybe the parameters too. If automatic stack expansion was on, the compiler would then generate the weird instruction, which was not useful to the program but would apparently cause the allocation of more stack space if necessary. I have just found the reference in the manual: "6.6.1 The Run-Time Stack Automatic stack expansion code makes procedure entries a little complicated. To ensure that the stack segment is large enough before the procedure is entered, the Compiler emits code to 'touch' the lowest point that will be needed by the pocedure. If we 'touch' an illegal location (outside the current stack bounds), the memory management hardware signal a bus error that causes the 68000 to generate a hardware exception and pass control to an exception handler. ... then allocate enough extra memory to the stack that the original instruction can be reexectuted without problem. To be able to back up, the instruction that causeed the exception must not change the registers, so a TST.W instruction with indirect addressing is used." It then goes on to talk about a compiler fudge factor and what gets generated if more than 32k of extra space is needed on the stack, and what is needed if working in assembly language. Best regards, Roger Holmes.

This is an argument that people in archives and museums have to confront every day when donations come in. If there was infinite conditioned storage space time/money to process donations, much more would be accepted than happens in the real world. As a curator, I have to make the decision to commit CHM's resources to preserve something in perpetuity. From the time I have spent talking to Doron Swane about the British Science Museum's collecting policies this is not unique. "You cannot save everything, where would you put it?" isn't a joke when you are talking about collections expected to last hundreds of years. One of the most serious responsibilies that I have, along with the activities of physical and electronic artifact preservation at CHM is making the decision to accept an artifact into the collection. Things created in the PC era and forward are especially difficult, since there was so much produced in a fairly narrow product niche (personal computers). Do you need to save EVERY version of a software package (and all of the documentation)? Remember, storage and processing isn't free.

Well OK 5k dollars is not much, but in January the following year for 10k, Apple's Lisa had several of the above, though I have to admit I have seen some spectacular crashes as it was possible to corrupt the sound buffers and also to seriously derange the CRT scanning. The compiler generated some strange code to 'touch' the new top of stack on subroutine entry so the OS could allocate all the extra space in one go rather than in little bits. One enterprising British software house even got Unix running on a Lisa with the (then) optional 5MB profile hard disk. It wasn't C.A.P. but one of the other big ones of the time. Before I left Marconi in 1980, we had at least one Z8010, but I don't know what date they became commercially available.

In a prior life I owned a company that was a Pick dealer (Pick Systems, Microdata, GA, Ultimate, etc.), so all kinds of interesting Pick-related stuff still floats around the house and I rediscover things from time to time. Today one has surfaced that I thought was lost forever. My father sold his business recently and in cleaning out things he found a QIC cartridge tape I had left there for safekeeping as an off-site backup many years ago. It's a GA (General Automation) Zebra Pick OS Dealer Sysgen tape. This is a tape that was only provided to GA dealers (for dealers to replace an end-users lost or damaged boot tapes, or to sell with new systems {the licensing was in the terminal ports, not the OS}). It was an Account-Save format tape of an account called DEALER-SYSGEN. On that account was stored the monitor and ABS sections for every different system GA made. A menu ran when you logged on to the account and it asked you what system you wanted to make an OS load tape for (1700, 1750, 2820, 3820, 3000, 3500, 5500, 7820, 8830, etc.), and what tape media you want the tape created on (QIC or 1/2 mag tape). It then wrote a complete bootable tape with bootstrap, monitor, abs, and files sections for any of those systems. What a find!!! Of course, I haven't tried to read this tape, perhaps it's got some worthless datafile backup from something else on it. But it still has the original GA Zebra lable stating it's the dealer sysgen tape and the write protect is on.... so I'm hopeful. I happen to have a GA1750 and a GA2820 in my collection, so I'm thrilled to know that I can make new boot tapes for them now. More importantly, I can make boot tapes for any other GA Zebra system. Note that this tape is for rev 3.8, which was the last non-R91 Pick GA produced (I wasn't a fan of R91, so I'm really glad it's the pinnacle of the 3.8 train). I need to see if I can find my manual patch sheets that bring it up to 3.8T1. Anyways, if anyone has GA Zebra's in their collection and needs a new boot tape I can help you out. Now I just need to find the DEALER.ASSY account for 3.8 :) Jay West
