It's finally been done... after many weeks of talking about it and not having it happen, Allison and I drove up to New Hampshire this morning and drove back with a couple of tall (H960, 6') racks with the following: pdp-8/a pdp-8/e pdp-8/f lab-8/e pdp-11/34a vr14 lps DECwriterII 3 RL01s 1 RX01 3 Diablo RK05-work-similar TU56 DECtape dual drive Funny thing... the pdp-8/e was originally Allison's... she had given it several years ago to the guy from whom I got all of the above... In return for her help, she took the pdp-8/f (smaller unit than the pdp-8/e), a core stack from the -8/e, and a second serial line card. I believe she is pleased... I know I am... I took pictures and hope to document the procedure at some point in the future... Now to get them all wired back up and tested out...

Just passing on a message from Jon Titus, the inventor of the Mark-8 Microcomputer (1974)... "I don't remember whether or not I gave you a formal acceptance for the Vintage Computer Festival. Put me down as a Yes. Would you have the organizers keep in touch with me about actual dates, etc? I'll need to do some advanced planning, and maybe I can include the trip as part of a business trip.

Just another Rinky-Dink Florida hamfest

by edick＠idcomm.com

There were several manufacturers of cards shaped more or less like the S-100. One of the more common ones was the MOTOROLA EXORCISOR series, which were MOT's development system for their 8-bit devices. The way to start figuring out what you've got is to count the contact positions at the edge connector and determine the pin spacing. The S-100 used 100 contacts at 0.125" spacing. It also had on-board voltage regulator(s).

Kitchener, Ontario, Canada declared safe haven for vintage minicomputers.

by kstumpf＠unusual.on.ca

There are very few computer collectors in Canada, especially those collecting minis. Almost all of March I've been trying to seed the small collector-base in southern Ontario by selling a bunch of DG NOVAs. NOT ONE TAKER nor interested party. Remarkable. Perhaps my prices were too high, but if someone wants something bad enough you would think he or she would at least contact me. Not one phone call or email. Weird. So it is because of this experience I recommend shipping any precious minicomputers to Kitchener. They are safe here. They won't be sold, tinkered with, or cannabalized. They won't even be LOOKED AT. This isn't a last resort pitch because I plan to hold onto the NOVAs. I originally needed the space for twin PDP 11/70s, but the corporate management of the present owners have put a hold on the transaction. Double yikes, eh. Thanks for listening and happy collecting. ---------------------------------------------------------------------------- ------------------------------- Kevin Stumpf * Unusual systems * www.unusual.on.ca +1.519.744.2900 * EST/EDT GMT - 5 Collector - Commercial Mainframes & Minicomputers from the 50s, 60s, & 70s and control panels and consoles.

Just another Rinky-Dink Florida hamfest

by edick＠idcomm.com

Yes, that's probably a chassis for a 9900 system. I once marveled at the similarity to S-100 when it was shown to me in a TI sales office when I was considering using TI's 9940 single-chip microcontroller in a product. I've never seen one of these boxes that wasn't for sale, and the last time was ~20 years ago. They're quite an oddity. I wouldn't hold my breath until I see cards for one, though. This card set was not the same as the 990 card set. You can tell these cards, even with the connectors cut off, from S-100 by virtue of the S-100's on-board voltage regulators, so I wouldn't let that worry me. As little as I do remember about the system, it was quite unremarkable, not "better" than S-100 because of the lack of software, and not more attractive than it was because TI was the only vendor of boards, hence tye owned the market for both software and hardware. I'm not even sure it was appreciably faster than the typically 8-bit processors found on the S-100. It did claim to be a 16-bit architecture. They did claim to have SOME software, though I don't remember much about it. Unfortunately, I recall having tossed out what documents I had about five years ago.

We "persauded" him to go back home and get them. The other guy stood right at the seller's spot for over an hour till he returned.

Compaq Deskpro XT

That sounds like part of what I was thinking of as well... a place where people could bring all sorts of random PC parts and help put systems together for people who might not otherwise be able to afford a computer system... We'd be able to do a service for people... >Seriously, I think your concept is good, biggest headache is floor space, >my bet is that you need to set up in a smaller place, a country town, not >too far from a big city, but where the rents for warehouse space don't >look like the NASA budget. I suspect this is why most museums I've >seen/heard of concentrate on desktop stuff, they don't need a huge area >to house it. That is a problem... cost for space. I decided to call around today and see if I could get a ballpark idea of what space might cost. So far I've only gotten through to one place -- an old mill complex in Saxonville, Mass. When I called, I was told that all they had left was a 2500 sq-ft area... at *$8* per sq-ft. That's US$20000 (I believe for a year), $1667/month. If this could be a club formed as a non-profit organization, and if I could get $10/month out of people, we'd need 167 members just to pay for the space... Then we have electric, which I would suspect will be a major part of the cost for such a power-oriented hobby. I know of one group who has space at $3/sq-ft, and a person who posted recently saying that they had space for free... I've got a call into Whittier Partners about space at the Maynard, Mass. mill complex (birthplace of DEC) but have not gotten a call back yet. Does anyone know if there might happen to be any grants or something equivalent that such an organization might be able to apply for? Doing a little more thinking about memberships, I was thinking of a tiered approach (typical) which ranks members on their level of usage of the facilities. And maybe there could be breaks for those who provide help to others...

Another Lisa question

by rigdonj＠intellistar.net

OK I've done some checking and found out that there is supposed to be a parallel port availble inside the Lisa 2/10 (aka Mac XL). Does anyone know where it is? What's it used for? There are two serial ports on the back of the 2/10. Are they the same and what are they used for or are they standard RS-232 ports? This one came with an anti-glare filter in front of the CRT but the other two didn't. Is this standard or was it an add-on? Thanks for all the replys, Joe

Lisa question

by Marion.Bates＠Dartmouth.EDU

Re: memory error. According to the table of memory errors, 70 means read/write error and 71 means parity error. Don't know if that helps at all...the whole error table is here: http://www.cs.dartmouth.edu/~woz/lisatech/page16_17.html The same board failed in my Lisa 2 last summer. I guess try jiggling it, cleaning the contacts, looking for cracked solder points, etc. Sun Remarketing sells the whole board (unless they've run out), but it's not exactly cheap -- around fifty bucks. And you have to get hold of the right guy on the phone, some of the younger sales reps have no clue that the company sells Lisa parts. -- MB --- You wrote: I picked up a Lisa today but it's missing the "V" key from the keyboard.

Any interest in Windows/286?

by gregorym＠cadvision.com

While browsing at one of my local thrifts, I found a large number (20+) of disk sets for Microsoft Windows/286. Each set seemed to be 3-4 disks (Setup, Build, Options, PC Paintbrush ... can't remember what else). There were no manuals, but the 5.25 disks seemed to be in good shape. Is anybody interested in these? If so, I can pick them up tomorrow and make them available to anybody who has a use for them. Let me know.

You're right on the money with this assessment! I'm convinced of this because when I look at the items you've listed I think, "goodness! Why would anyone want that stuff?" while when I look at the pile of equally esoteric S-100 stuff I have in the corner, I think of it as "good stuff" which of course is a purely arbitrary judgment. I am not a collector and have held onto my "stuff" for two reasons, which I think may be pretty common in the world of computer "junk" ownership. (a) I bought the "stuff" when it was current hardware and I needed or wanted it for some specific purpose and still hope to squeeze the remaining value/utility out of it, and (b) it's a daunting task sifting throught the "archive" to determine what has to "go." This combines itself, quite naturally, I believe, into "Well, one of these days . . ." Auction prices would yield useful informaton IF . . . and only if. . . there were a completed sale to go along with a set of finishing prices published on the web. What's damaging to the usefulness of what we have now, e.g. eBay, is that they allow an auction to run to completion, record the final (winning) bid, and make no assertion whatever about whether the sale actually happened. As a consequence, putting your goods up for auction on eBay or Haggle is pretty chancy, as the only thing you're guaranteed of getting is a bill. That leaves the observer with a big question mark where an answer to the question of "What would someon give for this?" comes up. In the meantime, I, a potential seller, sit here saying to myself, "All I really want is for this stuff to GO AWAY!" When I advertise it as available, I get all kinds of offers to "take it off my hands," which means people will let me gather it up, package it, and ship it to them, on the off-chance that they'll use it for something, provided, of course, that I don't mind bankrolling the whole project, and what's always in the back of my mind is "I wonder what (how much ) this stuff would bring at auction?" If there were just a realistic way to find that out . . .

Seller's market

by edick＠idcomm.com

The information I got from eBay's site suggests that only 70% of the auctions which are completed result in actual sales. What I get from this is that nearly one in three auctions which result in a fee to eBay don't result in a sale for the seller. I would say that the items with "ridiculous" initial prices are not included in this figure. That situation seems quite plausible to me, as there is no means availailable for "forcing" a sale. The fact that someone bids doesn't obligate them in any real way, nor does the fact that someone lists an item for sale obligate them to sell it if the price isn't sufficient. It seems quite plausible to me that an individual might overbid on an item in order to "queer" the auction, running the price up to where no one would pay that amount, irrespective of the value of the item being sold. This is no different than publishins software with a virus, or spraying graffitti on someone else's building. There's really no penalty.

HP equipment

by lemay＠cs.umn.edu

Does anyone recognize these items: HP 9145: appears to be a cake-box size unit, with a cartridge tape drive of some sort. HP 98571X: probably a computer or some sort. has a expansion slot in back, whatever was in teh slot has been removed. rs-232, HP-IB, HP-HIL, thinnet connectors on back. Seagate sticker applied on side of unit claims it is TEST EQUIPMENT, and is called HP 340 CPU serial number 334. PS: I may have a line on a pair of 3B2's (somethingorother/300), and the base unit for an Amiga 2000. -Lawrence LeMay lemay(a)cs.umn.edu

PS/2s nicer than expected; some questions

by gregorym＠cadvision.com

Over the weekend I acquired some interesting PS/2 machines: a PS/2 P70 386 portable, and a PS/2 Model 95 XP 486 server. This was my first experience with the PS/2 family, and I was pleasantly surprised. From what I remember when PS/2s were new, the media savaged them, mainly due to high price and the incompatibility with all existing ISA cards, RAM, etc. I was impressed with the build quality and design of the machines (the power supply in the M95 XP486 for example: undo one butterfly screw and the whole thing swivels out, allowing easy access to the drive bays) and with the ease of configuration of Microchannel cards - better Plug and Play than with many peripherals on Win 9x machines. Some questions: 1) Why did Microchannel fail so completely? From a user point of view it seems quite nice. 2) Can MFM or IDE drives be used with an ESDI controller, or do the drives have to be ESDI drives? 3) Anybody know if the 486DX33 on the processor board can be replaced with an Overdrive chip to make it at least a 486/66; or, does IBM still run their parts depot in Boulder for old machines? 3) I'm having some trouble with the P70. Originally, it wouldn't boot at all. I ran the diagnostics from the Reference Disk, and all tests were passed. I re-ran the Auto Configuration with no errors. I installed PC-DOS 6.3, and formatted the built-in HD at the same time. Everything seems fine, but the system won't boot from the hard drive alone. If I boot with a floppy in the drive, I can access the HD and run programs off of it. But without a floppy, nothing works. Any ideas? Thanks in advance. Mark.

Ohio Scientific Model 560Z CPU (PDP-8!)

by edick＠idcomm.com

Back in the old days, somebody or other, I'll look it up later (General Instruments, I believe), made an LSI which was essentially compatible with the PDP8-E. The idea was that it was much less of a maintenance headache to have the CPU in microelectronic form as opposed to the ssi-msi implementation commonly seen. These didn't fare to well on the market because of the rapid evolution of the commercial microcomputer industry.

Seller's market

by sinasohn＠ricochet.net

>If I sell to you for $50 when someone else offers $500, the blame is on me >for taking less than the highest offer, Keep in mind that money is not the only method of payment. That situation could easily be $500 cash or $50 and a promise to care for it the way you would want it to be cared for. >You've undoubtedly read my comments about the low (70%) completion rate [...] >walk away, having ruined the auction by bidding out the more serious >bidders, when there was no serious commitment to buy. A couple of comments: sellers can (and often do) contact the second highest bidder if the first "walks away". Also, I think there may be other reasons for backing out than the malicious attacks on sellers suggested earlier. Shipping might be one reason (I recently "walked away" from a couple of DEC computers I bought on eBay because of the shipping. (I'm sending the guy the full bid amount plus shipping on the items I *do* want; he was nice enough to throw in a couple other computers to replace the ones I didn't want!)) In any case, a 70% completion rate is not necessarily a sign of people artificially raising bid prices with no intention of following through. >EBay does charge the would-be seller a fee based on the final bid price and >not on the actual selling price. It benefits them to have the prices as >high as they will go. Okay, so yes, the eBay people sit there, rubbing their hands and cackling gleefully as they watch the selling prices for altairs soar through the roof. But what is it that they do (other than provide the service) to encourage the higher selling prices? >My belief on this matter is that the very thing which drives the prices up >is also the thing that causes the high transaction failure rate. but eBay doesn't get paid if the trx falls through, so it would make sense for eBay to prefer a lower commission on a smaller sale than no commission on a sale that doesn't go through. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Rebirth of IMSAI

> I don't know if $500 is the right number either, but I figure that in a >"new" IMSAI 8080 kit in low quantities, there'd be at least $75 in boards, >$100++ for the case, $50 for the power supply, $25 for a silkscreened front >panel and the rest, silicon, passives, switches, and the backplane >connectors. And that doesn't iinclude any re-engineering costs to account >for parts that have been discontinued or marked as "end-of-life." You forgot one vital component: the switches. The 7101 and 7103 series switches used in the IMSAI front panel are still available new from C&K, at $5-$6 each. They start adding up fast! And cost of a full-length (22- slot) backplane would come to around $150-$200 these days. (Though you could easily argue that now that we have memory boards larger than 4kbytes you don't need all those slots, all of my real IMSAI's have 22-slot backplanes...!) A year or so ago I looked at what it would cost to make my "TIMSAI" IMSAI clone into a commercial product. Street price, I calculated, would be about $2000, and most of that was in the metalworking. There was only about $30 in semiconductors in the whole unit (and that included 256K SRAM and an IDE/floppy controller). -- 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

Question regarding a VAXstation

by cem14＠cornell.edu

First of all, let me introduce myself to the list. My name is Carlos Murillo, computer enthusiast and HP collector, though my collection is still pretty small. Many of my choices when it comes to computing are influenced by my addiction to automation and data aquisition. I have been lurking for a few weeks now, and I have learned a lot about classic computing from the members of the list. Thanks to you all. Now, I would like to ask for advice: I have a VAXstation 4000/60 sitting in front of me. I have been told that this ran ok about 8 years ago; I really don't know if this fits the topic of the list (I guess it could be slightly newer than 10 years). The thing is, it won't boot. When it is turned on, it flashes several colors on the monitor, it tests its 16M of RAM and then it aborts and dumps me to some sort of monitor program. This is what the screen shows: KA46-A V1.1-31E-V4.0 08-00-2B-2A-F8-AB 16MB <bargraph representing memory tested here> ?? 003 3 DZ 0112 <---loud beep heard here >>> _ I played with several of the monitor commands; in particular, here are two that seem to give some info about this machine: >>> show dev VMS/VMB ADDR DEVTYPE NUMBYTES RM/FX WP DEVNAM REV ------- ---- ------- -------- ----- -- ------ --- ESA0 08-00-2B-2A-F8-AB DKA300 A/3/0 DISK 209.81MB FX RZ24 4041 ..HostID..

Question regarding a VAXstation

by cem14＠cornell.edu

Thanks to everybody for the information. Indeed, the missing mouse was the culprit. The next time it loaded VAX/VMS V 5.5; it started by asking for the date, and I made the mistake of actually providing the current date; as it loaded, I got about a hundred instances of "license has expired for XXXXXXX", with XXXXX being a bunch of installed software, including FORTRAN and Pascal compilers and a lot of things that looked like networking stuff. Oh, well, I guess that by booting the machine I have stripped it of a lot of software. Finally, a login screen popped up, but nobody around here remembers any user name or password. It is the first time that I have seen a machine boot VMS. Nice. Carlos.

Partial OS/8 Software Support Manual online

by IVIE＠cc.usu.edu

Having been blessed with a bit of a lull at the office this week, I've typed in and HTMLized a chunk of the OS/8 Software Suport Manual. The parts I have so far are the introduction through Chapter 5. Web on over to http://cc.usu.edu/~ivie/ and click on "The OS/8 Software Support Manual". The copy I have is a copy of a copy and no one bothered to copy the back of the title page, so I don't know the date or version of this particular copy of the manual. I also don't know when I'll get to the appendices. The appendices, of course, give the really exciting details such as the directory format. The part I have done so far may be interesting to that fellow who complained a while ago about having a DECmate III and not knowing how to program anything on it. Roger Ivie ivie(a)cc.usu.edu

The DZ is programatically similar to the DZ for UNIBUS and the DZQ/DZV for Qbus. It is a multiple asynchronous serial line multiplexor (I don't know how many lines on Vaxstations...) I'm not familiar with the 4000/60... but if it is anything like other Vaxstations... the DZ is usually connected to the keyboard and the mouse. If you don't have these, then it may report an error (missing the mouse may be enough).

But the winner's curse afflicts auction eBay is not selling futures. It's selling objects which (at least in terms of classic computers) are not being purchased (by us, anyway) with plans to resell at a profit. So for us, if we think an altair is worth $10, and we're outbid, we lose nothing. The guy who bids $10K and wins, may feel it is worth that much to easily and quickly obtain something they want. Again, no problem. The guy who bids $10K and wins, hoping to sell later for more money is either a) a shrewd investor and we're all just jealous, or b) an idiot who is going to lose his shirt. In the case of the latter, all it means is that we have to wait to get the altair for $10 until the fad dies down and we see naked guys wandering the street carrying altairs.

Our Spectrum Management Agency (or whatever it's called this week) has a less enduser friendly attitude towards dipsticks in fringe areas that think they should be able to watch marginal signals on "rabbit ears" inside a substantial building. It amounts to "Get an outdoor antenna." No outdoor antenna, no valid grounds for complaint. There are no specific regs regarding emf emission >from computers, they have put the onus on the RECEIVER manufacturer to ensure adequate filtering & shielding from unwanted signals. The CB fad of the 70's was a direct cause of this, after it was discovered that perfectly functional CB's would drive certain televisions berserk because of stupid choices of IF frequencies (Amongst other "They did WHAT!" type design, um, features.) If you have a properly installed external antenna (Yagi of some kind - cut for the channels you are trying to receive) and proper coax feed into the set, and you are STILL getting interference, only then will they look into it.

The oldest ones could be about twelve years old but they were made for several years. They are for reading DOS format 5.25" floppies on a Mac. Dayna made several variants for reading 360K and 1200K disks. I think that you'l need a system extension as well as the hardware itself.The drives should work on virtually any SCSI capable Mac, but they are >from the Mac II generation so don't be surprised if they're incompatible with recent system software. Dayna don't have a great record of supporting older hardware, alas. However these things do pop up rather a lot and the power supply pin outs have been posted on the comp.sys.mac.* news groups in the last year or so, so check out DejaNews.

sellers market - firearms

by Watzman＠ibm.net

E-Bay banned fire arms for two reasons: First, they couldn't do the background checks or check for stolen weapons. A legally valid reason, but likely an excuse. Second, if someone were assaulted with a weapon bought on E-Bay, the way things are going, E-Bay could be sued, and lose, BIG TIME. That's probably the real reason.

Mark-8 microcomputer - interview with Jon Titus

by adavie＠mad.scientist.com

Hi Guys and Gals. No, I'm not "back" but thought you might like an interesting read. I've been working on interviewing Jon Titus, the creator of the first "home" computer, the Mark-8 Minicomputer - which was featured in the July 1974 issue of Radio Electronics. Jon was kind enough to spend a considerable amount of his time typing up memories of the machine and how it all came about. I've placed this on my site, along with a few images. One image, of the RE front cover - was sent to me or I grabbed it from some website - but alas I can't remember where or by whom. So, if it's yours please contact me and I'll talk to you about copyright/image theft, etc. Without further ado, point your browser to http://www.comcen.com.au/~adavie/weird/mark8b.html I'd really like some feedback on this one - it's taken a fair bit of work! Cheers A adavie(a)mad.scientist.com

Remember that big blue has different brands and I can only assume that the R6K division didnt like the PC company giving it competition. correction: for CONSUMER machines, MCA was discontinued unfortunately.

Well, I've been involved with various collectibles for nearly 30 years, and I have to agree. I bought two Chein tin wind-up Donald Ducks last fall through eBay for ridiculous prices -- about 25% of what I could have turned around and sold them for at any antique show. And the Sharp PC-5000 I got for $15 was pretty ridiculous, considering the significance of the machine. >Think of it this way: if a toy stuffed with beans that cost a couple >dollars to manufacture were to be made for sale in a way which makes >people perceive a scarcity, and that toy was then subsequently priced up >to $1000 because of dealers and price speculators feeding on the perceived >scarcity of that toy, is it really worth $1000?

Hmmm... Sounds like numismatics in the 80's, gold and silver at various times, collector plates, etc., etc., etc. And your point is? Speculators who buy based on fads are idiots. "Buy the book before you buy the coin." Smart folks do their homework before spending a lot of money. No matter what the "investment opportunity!" is, those that get in before it hits big and get out at the peak make a lot of money. Those that don't, don't. (Think back to around 1929...) Btw, I still don't have a Commodore SX-64, one of the few portable versions of an 8-bit home machine, in my collection. There have been a lot up for bid on eBay, but they all seem to sell for just over $100. (The same price as they were going for at VCF 2.0, btw.) That's more than I'm willing to pay for a Commodore 64, no matter how portable. On the other hand, I put out close to $300 for 2 Zorba's (with Shipping from the east coast) that I got through eBay. I don't think that that's a ridiculous price to pay for a rather uncommon machine. (Especially since I'm getting manuals and software, plus a couple of Kaypros, an IBM portable, and a couple of other goodies to go with it.) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

'0' is the id Apple traditionally uses for the internal hard drive, though it doesn't have to be. A Mac can boot from a SCSI HD with and id setting (eg. I've booted a Mac Plus off a Zip drive, which can only be set to id 5 or 6). If the hard drive doesn't have a System Folder, you should be able to just copy one off a boot floppy. This will usually work, though you'll have a very minimal system. Tom Owad

Kits vs ready-made (was RE: Rebirth of IMSAI)

by edick＠idcomm.com

Kits appeal to a much smaller segment of the market. Here in the US, selling kits offers a way to avoid having to meed stringent FCC specifications for electromegnetic interference, among other things. For that reason, if I were going to get into the business of selling a product, I'd let the initial kit sales pay for getting past the FCC testing/approval procedures. That way there would already be kit users out there to assist and teach ready-built product users so I would not have to do that. Kits are often more costly than ready-built products because kit builders fix their mistakes, while you can't expect the user of ready-made stuff to fix your mistakes. Tech support is a necessity, yet most kit builders don't need it. Tech support is what costs when you're selling a ready-built product for the home computer market. What scares me about the notion of resurrecting the really old IMSAI product line is that some of the designs, and this is more true of ALTAIR than of IMSAI, by the way, took the characteristics of the logic family they were using, mostly standard TTL, into consideration and would probably suffer >from glitches and other timing race conditions e.g. metastability if current-generation and available pin-compatible HCMOS or LSTTL logic were substituted. This probably wouldn't be too common, but I've done this (long ago) when these logic families were new, and had mixed-to-poor results. Mostly this was the result of placing a fast decoder where a slow one had previously been specified, and mostly the result was not serious except where one-shots (YUCHK!) and clocked logic were driven by it. This was particularly true in DRAM circuit interfaces.

CBM bonanza!

by black＠gco.apana.org.au

As anyone who follows any of my posts knows, I'm a dedicate Commie collector-freak. Well, today I scored the jackpot. Went to Glenorchy Tip Shop, one of the women that works there grabbed me & took me out the back (no, my luck hadn't changed) & said "I've been keeping something for you". Some business that had been holding old Commodore inventory dumped 12 removalist boxes (tea chest size) on 'em.... For $50 I scored 6 1571's, 3 1581's, 4 Commodore 128D's, three more 64C's, several CBM modems (1670's), around 40 cartridges, two more MPS 803 printers, two VIC 20's, two Xetec CBM to Centronics adaptors & a multitude of VIC, C64 & C128 software.... everything was still boxed & plastic wrapped.... This'll keep me happy for ..... ohhh.... a week or two :-) (Time to open a Commodore museum I reckon, the house no longer has any room ....... & my partner is threatening to move out.... oh well, the 'puter are more entertaining anyway.....) cheers, Lance

Rebirth of IMSAI

by edick＠idcomm.com

That's exactly what Todd Fischer was writing about building. I certainly hope he doesn't do it. Those cases or, for that matter, any cases, in low volume, meaning fewer than, say 5000 per week, would be the bulk of the cost of nearly any computer. When you can use the most sophisticated machinery to make a simple product, however, the cost comes back down around $3 per pound. That's why, although I can't buy a decent fan for my power supply for under $40, though I can buy a power supply for $35, I can buy the case, with power supply and a fan, though still not a "decent" fan, for $27. It's the economy of scale.

I got from a good source that the >reason MCA was discontinued was because if the bus speed was increased in >order to keep up with PCI, that would have started encroaching on the RS/6K >machines. That's an extremely confusing statement, as MCA is quite common in many small-to-medium RS/6000's from just a few years ago. How can MCA compete against RS/6000's when it's part of many RS/6000's? I'm also confused by your statement that "MCA was discontinued", as IBM continues to sell RS/6000's (both the R50 and the SP system 9076 are listed in their February 1999 sales brochure) with MCA busses and MCA cards and MCA peripherals. -- 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
