The Saturn (which is used in a lot of later HP handhelds, including the HP48 family) is a strange chip. I'd not call it 20 bit, though. Addresses (nybble addresses!) are 20 bits, most registers are 64 bits, and the ALU is (I think) 4 bits. Call it whatever size you like. > -tony >

A boot disk will not work either. Does the floppy drive LED light up during startup? It should, whether or not the HDD works, and you should be able to boot from a floppy, even with a dead HDD. Therefore if a boot disk doesn't work, either your floppy system is defunct or it's in the motherboard. An easy fix -- which doesn't always work -- is to disconnect and replace all cables. It's fairly easy -- pull cables one end at a time *only*, so you don't forget where they went. Each device has 2 things going into it...a flat (usually, grey, sometimes blue) ribbon cable, for the data; and a power cable. Both are keyed, so you can't put them in backwards. Trace the data cable from the floppy(ies) back to the controller card, and pull & replace. Those are usually pins, and *can* be replaced backwards, so take care. You can swap the controller card into another slot -- any slot should work. If all slots are filled, exchange two cards. Chips work their way out of their sockets ("chip creep"); push every socketed chip back in. I have boxes of cables, controller cards and drives if you need any; e-mail me. If the floppy disk does its thing, are you sure the floppy itself is OK? It must be low density (you can tell by the hub ring) and have the proper files; try booting another machine with it. Not all DOS's will work on all machines -- I've even seen some older machines that won 't boot under DOS 6.x

I have to admit that I gave away my 600XL in favor of the ST long before the thought of collecting computers ever hit me. Similarly, my ST's and Falcons are pretty much dedicated to studio stuff (and I don't get to "play" with that much these days) and I use my windows laptop almost exclusively (6-16hrs/day). Nonetheless, I am president of ABACUS, the Atari Bay Area Computer Users Society, and probably will continue to be for a long time. Atarians are somewhat lucky in that there is a reasonably strong vendor market, good user groups, and wonderful emulation options. Still, ABACUS has been experiencing a seriously declining membership recently as people traded in their ST's for PC's. We talked about it, and decided that what even the PC people didn't want to lose was the "family" we had built up in the club. There are lots of PC user groups, but none with the character of ABACUS. (How many clubs have a Land Rover owner, a waffle collector, and a 76 year old newsletter editor?) So we changed a bit to meet the new focus of the club members. We now have a "PC SIG" and demo PC software and hardware at the meetings, along with ST stuff. We feature general interest (computer) articles in the newsletter (such as my never-ending part 2<x> of my 3 part series on building web pages) as well as humour and general commentary. We continue to support the ST/Falcon folks as we expand to service the new interests of members. This lets members move on to newer things (graphical web browsers (yes, we know about STiK/CAB, but it's not netscape), CD-ROM's, etc.) while still keeping the ST alive. But, we've not done much about getting new members (either PC or ST). Your message has gotten me thinking, though. Every now and then I get a call >from someone who's got an ST for sale, and I have to tell them there's just not much market for them here. Perhaps we could set something up to get those machines into the hands of someone who could use them and is otherwise unable to afford them. (Goodness knows we've got enough kids with no $ around here!) The biggest hurdle facing the general public in putting older computers to work is the lack of support. (P.S., Cliff Stoll is an idiot sometimes.) They can buy a PC at Circuit City and half their neighbors will be able to set it up for them or answer questions. (Etc.) Not so with machines not quite so mainstream. But if user groups made the effort to become known and to support these computers, they could do a lot of good. Maybe even working with teachers or youth programs to make the computers available, and the kids *WILL* use them. I've seen it happen and I know it makes a difference. (My living room is loaded with older Macs -- until school starts again.) Anyway, sorry to blather on so long, but I think that "obsolete" computers are still useable, valuable, and beneficial. So lets talk about turning people on to them! --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

Laser 50 computer

by coslor＠pscosf.peru.edu

I posted a message a day or two ago, and I wanted to thank Sam Ismail for responding. I am wondering if anyone else might have one of these Laser 50 computers available (Sam wasn't able to part with any :-( ?? Some more information on this computer. It was manufactured by V-Tech (Video technology Ltd.) in the mid 1980s. It was a small, white, lap-top size computer. It had a single line LCD display and was marketed as a childrens education or beginner's computer. You could expand this 1.5k system by buying cassette recorder, two different printers, and a memory expansion cartridge. OH, yes... you could save up to 9 different programs internally on the computer. Now I also remember it ran on batteries though you could hook up a DC converter to plug into the wall. Had a full-feature BASIC programming language built in, including sound commands... although it didn't have any graphics capabilities (that I know of) it was a fun little computer. Anyway, what I am asking is if anyone out there has one of these or knows where I might be able to find one.... PLEASE let me know. I used to have one (lost it YEARS ago) and I would like my children to be able to use it a bit... plus it's kind of a piece of my computing history that I would like to bring back to my collection! Thanks a lot, and I hope someone has an inkling obout this machine. P.S. This isn't an Apple or IBM close. Best Wishes, CORD COSLOR //*=====================================================================++ || Cord G. Coslor P.O.

(Goodness knows we've got enough kids with no $ > around here!) An idea. Sell them the machines cheaply, and then allow them to attend your club meetings for (say) one year free of charge. Having been involved with many user clubs, I realise that the membership money does go to good use, and that it costs a lot of money to produce and print the newsletter. But a lot of people don't see it that way. It costs nothing extra to have a few extra people at meetings, and (a) they will get support for their new toy (thus keeping it running) and (b) may find how useful the club is and will thus join. > The biggest hurdle facing the general public in putting older computers to > work is the lack of support.

I may not care for the Apple ][ hardware design, but it is an extremely important computer historically. I don't tend to use this class of machine too much. c) I got them because if I hadn't they'd have been lost for ever.

I hate to say this here, but I would _not_ recomend a classic computer (any classic computer) as the only system for a non-computer-literate user. IMHO such a user will quickly become disapointed when they find that the things that _they_ can do with the machine are somewhat limited, and that nothing from the local computer store will be of any use to them. I can have advanced video on one of my older machines because I am prepared to write drivers, solder up interfaces, read technical manuals, patch existing programs, etc. OK, I enjoy it. But to suggest that a PERQ 2 driving an I2S image processor and a homebrew GPIB -SCSI interface would be a good machine for the average home user to view his photo-CDs on would be nothing short of insane. Yes, it _could_ be done, but for such a user, a normal, boring, PC-clone would be much more suitable. Even I don't use a classic machine (or at least, what _I_ consider classic) all the time. Earlier this week I needed to write some letters. I could have used a classic-PERQ and printed the results on a Versatec V80. I could have used the paper tape editor on my PDP8/e to punch a tape containing the correct postscript commands and then printed it to my laserprinter using a serial-interfaces paper tape reader. In fact I used something non-classic - a much hacked PC/AT running Linux. I used LaTeX to format the text, and then printed it on said (fairly modern) laserprinter. There are plenty of other things that would have been just as good, but that's the one I chose. The people who (IMHO) we should be trying to attract to classic computers -- and in fact the ones I've had some success in attracting -- are those who are already computer literate to some extent. People who already can write simple programs and want to understand exactly how a system operates. I think it's a lot easier to understand many classic computers (minis and micros) than modern PCs, and the educational value of such machines should not be overlooked. There are (IMHO) at least 4 different types of tasks that can be done with computers : 1) A standard application for which software (commercial, GPL'd, freeware, shareware, whatever) already exists. In which case you pick whatever machine the software runs on. If it runs on more than one system, you choose between them using whatever criteria matter _to you_ (hence me picking a classic computer for its better documentation over a modern PC since both can carry out the tasks I want to do) 2) An existing embedded system. Although it's possible (and sometimes common) to 'modernise', say, a control system based on a minicomputer, there are still a lot of PDP8's and PDP11's running machinery, etc. Provided the old machine works reliably and support/spares are available, it's fine to keep on using it. 3) A new 'embedded' system. Although my example of the I2C chip tester was, I agree, slightly contrived, I was simply pointing out that if you are making a single-purpose machine _for youself (so you can maintain it)_ there's no reason not to use a classic. There's probably no reason not to use something modern either. 4) Education. This includes 'writing programs for fun', understanding how computers (hardware and software) works, etc. This is IMHO the main use of classic computers to the average person these days, and the way we'll attract more people into the hobby. I've said before that you can learn more about processor operation by spending a couple of days with a minicomputer CPU, the schematics for it and a 'scope than by sitting through most lecture courses on the subject. And, I can fully understand the joy that comes from getting a computer to do something that is widely claimed to be 'impossible'. When the CoCo was current, it was normally claimed that you couldn't have PMODE 4 graphics and Semigraphics 4 blocks on the screen at once. I did it, and totally amazed the staff in the local Tandy store. Since it's easy to do most things on a fast PC (you don't really have to save every last cycle, etc), it's more of a challenge to do them on an old home micro. Again, we may be able to attract people because of that. It may be worth looking at how (say) classic car clubs keep their membership. They may well have similar problems - why would you drive (say) a pre-war car when you could have a modern one. Rationally it probably makes very little sense... > My previous remarks about mainframes, which were interpreted as saying > that they are not "home computers", were made from the point of view > (and perhaps in ignorance) that, while C64s, Atari 8-bitters, TIs, > CoCos, and other "home computers" that were sold FOR THAT PURPOSE in > K-Mart and other department stores DO (or at least did) have a user > community, sharing programs, encouraging other users, forming User > Groups, publishing Newsletters, etc., other machines (such as the > PDP class of mains, minis, etc. and maybe Altairs and S-100 bus > computers) do NOT have this aspect to their existence. I guess I I will have to disagree with you there. The larger machines that I am involved with have very active user comunities who offer a lot of help and support to newcomers. To give a couple of examples : PERQ : When I was trying to add a printer to my PERQ, I had a few questions. The result was that other owners dismantled their own machines, 'buzzed out' cables, e-mailed me wirelists, and talked me through the whole thing. That's not an isolated incident - a person who was having monitor problems got other owners to pull the covers off their monitors and measure voltages, etc. This is just about the only machine where this level of support still occurs over 10 years after the entire line was discontinued. PDP11. The user community here is split (IMHO) into the professional users who need to keep the machine running, and who can afford DEC diagnostics, replacement boards, etc, and the home hackers who debug everything with a logic probe and printset, rebuild modules and even repair dead fans. I am certainly in the latter category here. But again, questions get answered. People will dig out manuals for obscure hardware and look up pinouts and jumper settings. Newcomers will get answers to introductory questions. BTW, I'm not flaming the support that other user communities give. I'm sure it's excellent, but I've never experienced it, since I don't (in the main) use those machines. > do know about DECUS; don't know if something like that existed for > PDP-11 owners or not, or even if professionally-oriented thing like > DECUS would be applicable here. I certainly did not mean to imply that The UK chapter of DECUS is pretty useless for home hackers. I am told that other chapters are a lot better in this respect. > * David Ormand *** Southwest 99ers * -tony

I know you can get some classic stuff for free, but unfortunatly, as with every hobby we love, it costs money. and here is an interesting idea- to beat microsnuff, write as many competeing programs that work BETTER than billy's ( not hard to do), and sell them. and with that cash, you can get more machines! <G> and remember, billy also writes MAC software, that for some reason are worse than you can get for IBM... so we support IBM and MAC, as well as your favorite classic, the more platforms supported, the better it is for everyone! :)

'Home' computer: Definition

by dlormand＠aztec.asu.edu

Somehow, a discussion I started of actually USING "home computers" (versus merely collecting them) degenerated into a fight about what a "home computer" is. And a sister discussion I attempted to start about putting "modern" applications on classic machines yielded discouraging words, too. I guess I should have started out with my ulterior motives. For a computer to survive as anything more than a relic, it has to have a user community. Now, I suppose I could use my TI for "typical home computing tasks" with the software I already have whether there was anyone else in the world using a TI or not. And I suppose I would, too. But for other jobs I wanted done that my computer COULD do (even if being a Web browser is NOT one of them), I would either have to program it myself, or find someone else to do it. And if I did it myself, most of the fun is sharing it with other TI users. And part of the fun of having this old computer is that there are other people bucking the trend along with me. In other words, we have a TI computer user community, and that is a very hefty reason for sticking with the TI computer. In fact, the TI community is shrinking, and as the members of the community observe it shrinking, some are inclined to bail out ("rats abandoning a sinking ship"). Given that trend, the community will waste away to a few hardcores unless there is new life added, either in exciting new "modern applications" or attracting new people to adopt a simple machine that can perform "common everyday household computing tasks" that they DON'T need a Pentium to do. Of course, while my main loyalties are to the TI-99/4A, I recognize all the other "home computers" suffer from the same conditions, and I was hoping to create a dialog for HOW to do this, particularly strategies to attract people to join the community, and to share technology of "modern applications" that one community may have successfully achieved and another could use. So what I was fishing for was the thoughts of those people who read this List and understand the dilemma. In a Wintel-dominated world, is it even FEASIBLE to try to attract other people to choose from the abundance of small computer systems, otherwise destined for the landfill or recyclers? My previous remarks about mainframes, which were interpreted as saying that they are not "home computers", were made from the point of view (and perhaps in ignorance) that, while C64s, Atari 8-bitters, TIs, CoCos, and other "home computers" that were sold FOR THAT PURPOSE in K-Mart and other department stores DO (or at least did) have a user community, sharing programs, encouraging other users, forming User Groups, publishing Newsletters, etc., other machines (such as the PDP class of mains, minis, etc. and maybe Altairs and S-100 bus computers) do NOT have this aspect to their existence. I guess I do know about DECUS; don't know if something like that existed for PDP-11 owners or not, or even if professionally-oriented thing like DECUS would be applicable here. I certainly did not mean to imply that these machines are not useful for "household computing jobs", and by no means did I intend that this mailing list is only for the classic "home computers" with user communities, or to exclude anyone else from participating. -- ********************************************** * David Ormand *** Southwest 99ers * * dlormand(a)aztec.asu.edu *** Tucson, Arizona * **************************** TMS9900 Lives! *

1980s Laser 50 computer???

by coslor＠pscosf.peru.edu

Greetings: I am wondering if any of you out there could help me out. I am looking to acquire an old educational computer that I had years ago called the Laser 50 personal computer. What it was is an old educational computer (for kids basically) produced by V-Tech, or Video Technologies, Ltd. around the mid 1980s. This machine was the size of a regular laptop computer and allowed small BASIC programs to be saved internally, and also had built in educational software, calculator, etc. The manual I still have for it says an additional cassette recorder could be purchased to save programs on, as well as printers, and a 16k expansion unit. Please let me know if you might have any information on this computer.... I would really like to find one for my kids. I am also looking to find the address for the manufacturer. I know V Tech still makes computer-like educational machines for youngsters today. I would appreciate your help. Thanks in advance, CORD COSLOR PO Box 308 Peru, NE 68421-0308 (402) 872- 3272 coslor(a)bobcat.peru.edu

by bw＠booster.bothell.washington.edu

Hi all. OK - here's the scoop so far on the Archival of classic computer stuff. Please give your input so that we can get the standards settled. The UW has graciously given me permission to attach a personal server to the network full time for ClassicCmp, so the underwork for the project is pretty well taken care of. I have a system that I'm working on setting up for the job - it will be a 486/66 with 32 MB of RAM and 3 GB of disk space. I am currently planning to set it up with linux. As you all know I am terribly slow about getting things done so it will probably be a couple weeks before it goes online. In the meantime we will continue to use the current FTP site which has plenty of space available. The particulars for how things will be stored are listed below for your review. Remember that the primary purpose of the archive is to store these items so that _someone_ can access them and make them available. It's probably not possible to always find a format that everyone can use, but if the data is here you can be pretty sure that you will be able to get it one way or another. System Software System software will be stored in a variety of formats. The preferred format will be disk images for those machines for which the means to create such an image has been developed. Examples are the Apple II/III (.dsk, .do, .po files) and C64 (.dsk files). The alternate format will be disk images created with a Central Point Option Board [1] which will read almost any 5.25" or 3.5" diskette. Those with such a board will be able to simply download and use the images. Those without will need to arrange to get a copy through regular mail. It's not a perfect solution but I can't come up with anything better. This will not cover 8" disks and I don't know how to deal with them as yet. General Software Non-booting software will be stored in the preferred compressed archival format for each machine (GZip where available). Firmware (ROMS, PROMS, PALS(?), etc...) I still don't know what a standard format for this should be. Anything which can be dumped to a file I'm willing to go with. My (limited) gizmo calls the format that it dumps to my PC "RAW". I assume that this is just the contents bit-for-bit. If anyone can read/write in raw format I'd recommend going with that. Documentation/Books/Magazines Text: Text should be presented in plain text, RTF, or PostScript. I will convernt submis- sions to conform to all three formats. Line Drawings: Should be formatted in either TIFF or PostScript format. Images: Should be formatted as either JPEG or PNG (Portable Network Graphic). I will convert PNG to JPEG on submission. Tag Files Each item will require a tag file to cover it's identification. This file is currently DS-form.txt located in the docs directory on the FTP site. It is probably not yet specific enough on the technical details - I will need recommendations on what to add. It does cover all the legal issues I wanted to address. Retrieving Files These files will be made available by FTP. Most will be easily downloadable by anyone. Some (Firmware, System Software) will be more difficult and will require physical assistance. I will generally be willing to create and mail disks for those who need them and can provide the media. I am poorly equipped to take care of firmware. Those without the neccesary gizmos will need to rely on the kindness of the group. [1] The Central Point Option Board is a device for an ISA bus PC that will read almost any standard floppy. They are still fairly commonly available for $20 or so. Bill Whitson

I have a couple for sale/trade, but I'm afraid my valuation would be somewhat higher than that :( I'd buy several more for $20 apiece if they could be found. If you want to spend a lot of hours sifting through vendors' junk-board boxes, you can find one without software or cable for maybe $1-5, and get the software off the 'net, but I price mine in original box with software & cable at more like $50 or trade. I'd trade one for a properly constructed/tested 34-50pin CompatiCard-to-8"-drive cable, OR a CompatiCard IV to replace my CC II. Kai > ---------- > From: Richard A.

Crappadore 64

by dastar＠crl.com

I have to get this off my chest. Commodore 64s have to be the god damn shittiest made computers ever. I had to test these 1571 drives that I sold someone and brought out 2 C64s I have in my garage and 2 power supplies because I know how notorious each part is for not working. I plug each in and niether work. I try the other p/s...same thing. I get ANOTHER p/s...both dead. I get yet ANOTHER power supply and 3 more C64 consoles I have. Of those 3, 2 worked! Is this a shittily engineered system or what? What bad weed were these idiots who designed this smoking? I've never had such bad luck with any other system. Out of all the systems I've ever acquired, the commodores and their stupid prone-to-burning-out power supplies have been the most likely to not work. I've gotten systems out of the rain that have been sitting in the elements for probably YEARS that have worked. But a C64? Hell no! Piece of crap! There must be some well-known fix for these idiotic things. I turn them on and get just a pure black screen. This is what happened to the first C64 I ever got from a friend 9 years ago. It just up and died on me all of a sudden one time when I was using it. Screen went black. There's got to be an easy way to fix these stupid things. Either that or there must be a well known joke passed around in commodore circles about how unreliable these junk heaps are. What a depressing hunk of crap. Aye.

I certainly did not mean to imply tha There are several groups for the PDP-8/10/11/vax other than decus but decus goes back to day one. What you forget is the intersil 6100 chip (pdp8! and the desktop version the DECMATE) and closed PDP-11 systems (PDT11/150 and PRO350) were sold in the same space and had very seperate communities outside of DECUS. It's not as cut and dried as your words picture it. Personal computing as adjunct to commercial computing was and is largely driven by cost, capability and software. Many amazingly poor machines did well not for the hardware but an abundance of software. Food for thought, The ti9900 chip is nearly as old as the 8080 and it was a 16bit design based on the TI990 minicomputer. Wouldn't you want that machine? FYI it was not that large (comparable to a PDP-11/20.). Yet the ti99/4a was year later...why? No support from TI, they figured you get the mini and devlope applications using the chip so support was limited. FYI, the ti9900 chip is a fairly high performance CCPU compared to the 8080! Allison

Extra stuff to go

by jeffh＠unix.aardvarkol.com

I have the following extra stuff taking up space if anyone would like any of it: 1) TRS-80 Model 4, desktop model with dual floppies and 64k RAM. works perfectly, and will include an original copy of TRSDOS 6. Asking $20 + shipping. 2) Sears SR2000 printer...dual interface IBM/Commodore 8bit. Seems to work fine though needs a new ribbon. $4 + shipping 3) Commodore Plus4/C-16 joysticks..a pair with the 8pin minidin connector. loose. unable to test. $5 + shipping 4) Atari SC1224 monitor...color monitor for the Atari-ST's. works great, though has some magic marker on the case. asking $10 + shipping I'm selling off these to make room for additional aquisitions, so if interested, please email me!

They're similar but I forgot what the main difference was other than the drives. I don't think the EX has a setup program like the HX's SETUPHX is one. Wonder if it's possible to change settings on the EX like the HX (EEPROM). Marc

Panasonic Handhelds

by dastar＠crl.com

I am posting this again to hopefully get more response. Right now we are collectively committed for 46 units of the Panasonic Hand Held Computers. I am hoping to at least double this figure. The more we want, the merrier for all. I'll include a little more information about these units. To those of you who have already submitted requests or have read this message, you can skip the rest of the message after my signature as you've seen it before. These units are a Panasonic HandHeld Computer circa 1984. They have a FORTH-like language in ROM called "SNAP". They have a built-in thermal printer. They have 8K of RAM running off a 6502 CPU. The custom-designed memory expansion tray which each comes with allows up to 10 additional 8K EPROMS along with the 3 that the HHC itself allows for. It has a 26 character by 1 line display, and its dimensions are 9" by 3.5". It has a full "qwerty" keyboard. Now please read the rest of the message for instructions on how to reserve 1, 2, 3 or more of these babies for yourself at a maximum price of $10 each.

As always Best Regards, Mike ------------------------------------------------------------------------------ END FORWARD So here's my plan...anyone and everyone who is interested, reply to ME (do not reply to classiccmp! People will hate you and want to drown your pets!) telling me how many you want. Do this soon. I will save all of your e-mails and then at the end of say, 10 days I will tally up the total and make Mike an offer. So again... Reply to ME only (dastar(a)crl.com) Tell me HOW MANY of the Panasonic HandHeld Computers you want. Do it SOON. You have about 10 days. Price will be NO MORE THAN $10 EACH. I'll get back to everyone in 10 days or so.

Sony CP/M machine?

Today's Wall Street Journal Article

by rcini＠msn.com

All: For your enjoyment... ------------------------ Rich Cini/WUGNET - ClubWin Charter Member (6) - MCPS Windows 95/Networking Why We Can't Part With Those Vintage PCs By G. PASCAL ZACHARY Staff Reporter of TIIE WALL STREET JOURNAI. When it comes to her husband's habit of clut-tering their Redmond, Wash., home with broken and outmoded computer gear, Pam Vavra knows where to draw the line. The kitchen. Last month, Brad, her husband, stuffed a Mason jar with dozens of old memory chips and put it on a shelf next to similar jars that held fruit. Brad thought "it looked cool," he says, but she disagreed. "The kitchen is mine," she told him. "Your chips don't go with the decor." It would be an exaggeration to say that in kitchens all over America, people are filling their shelves with old computer gear. But as computers become nearly as common as toasters, the space devoted to computer junk expands, too. To be sure, some people have always had a hard time throwing things away. Didn't everyone's grandmother save string? Like the savers of old, today's digital packrats can't help themselves. "The reason you can't throw it away like an old shoe box is pre-cisely because you've established a prior relationship with it," says Brigitte Jordan, an anthropologist at Xerox Corp. who studies the relationship between people and things. As computers become more sophisticated, Ms. Jordan says, human interactions with them become more in-tense, intimate and memorable, making it harder for owners to part with their gear. For instance, Jim Kelnhofer, a programmer at Microsoft Corp., keeps his first computer in plain view in his bedroom. "I turn it on once or twice a year," he says. Hanging onto old computer stuff isn't just sentimen-tal, though. Some people paid so much for their outmoded machines that they can't bear to part with them for a song. And with computers changing so rapidly-obsoles-cence typically occurs in three years-many owners com-bat the disorientation of rapid change by keeping their old stuff nearby. "My theory is that these folks are so giddy with the pace of change that they keep this junk around as a trail of intellectual breadcrumbs, leading them back to their computing origins," says Paul Saffo, director of the Institute for the Future in Menlo Park, Calif. That's certainly true of Mr. Vavra, a software programmer who keeps the first computer he ever owned (a Franklin Ace) in his garage. A year ago, he donated to Microsoft's museum his Apple Lisa, a precursor to the Macintosh, but he can't part with an original Apple II, a computer on which he wrote some of his first programs in the 1970s. It is even more common for people to surround themselves with old gear at work. Alan Cooper, a computer consultant in Palo Alto, Calif., keeps a line of old chips on his desktop computer monitor and a few hundred computer punchcards -- not used since the 1970s -- in his desk drawer. "That's a lifetime supply now," says Mr. Cooper, who uses them as bookmarks. Mr. Cooper occasionally tosses out gear, but not easily. He is still sorry about his decision five years ago to give away an original Macintosh to a public school. Whenever he considers tossing out, say, the Hewlett-Packard calculator he bought in college 25 years ago, he thinks about how much he misses the Mac. "I don't want to make that mistake again," he says. While vintage computers provide psychological ballast against the shock of the new, there are sound economic reasons for retaining obsolete machines: Many are im-possible to sell or give away. In California alone, an esti-mated two million PCs are abandoned each year. Many sit in closets or warehouses or under desks. Others are sold at yard sales, left on the street, or cannibalized by recyclers for valuable metals. Most charities, for instance, have firm standards on which computers they will accept as donations. “We don’t want your junk,” says Helga Luce, a spokeswoman for Goodwill Industries. Even perfectly good computers often can't be given away. The Detwiler Foundation, which donates to schools computers rescued from oblivion, doesn't take machines that are powered by anything less than Intel's nine-year-old 386 chip. "We're not doing a school a favor by giving them a 286," says Diane Detwiler, the foundation's executive director, referring to Intel's 15-year-old microprocessor. Some charities have even tougher standards. Gifts in Kind, an Alexandria, Va., nonprofit that distributes donated computers, will accept only those machines whose parts, manuals and maintenance are readily available. The charity won't accept, for instance, the Macintosh Classic, a venerable computer that sold in the millions. Thwarted in their efforts to give away their most ancient machines, some computer owners try to make the best of a bad situation. Cliff Stoll, a computer-security expert in Oakland, Calif., came up with a novel answer to the question, "What do you do with a used computer?" Mr. Stoll, who is a commentator on the cable channel MSNBC and an author, has turned a one-piece Macintosh Plus into an aquarium, hollowing out the electronics and filling the case with water and fish. As if the aquarium weren't enough, Mr. Stoll turned an old IBM PC into a litter box for his cat. While the cat became enamored of the box, "I realized that really isn't a good second life for a computer," he says. For some fanatics, giving their computers decent storage space is more fitting. "My reasoning is really very simple," says Marc Weiser, a computer scientist at Xerox's Palo Alto, Calif., research lab. "Old computers are worthless to everybody else, so even if they have a dime of value to you its a dime you wouldn't have otherwise." Mr. Weiser keeps three old computers in his garage, including one he built in 1975. "Maybe I'll show it to my kids someday. You know, like an heirloom." Other digital packrats harbor similar delusions. Kimball Brown, a market researcher in San Jose, Calif., thinks his motley collection of modems, compact-disk drives, memory chips and entire computers could be worth something someday. Even if he's wrong, he insists, he can't lose. "I have a dream that someday I'll open a computer museum," he says. But there already are computer museums, and they are pretty choosy, too. Curators want collectible computers to be in pristine condition and perhaps bear some unique mark, such as a designer's signature. "What turns out to be valuable, you can't really know," says Gwen Bell, co-founder of the Computer Museum in Boston. But "if it's not shiny and polished and isn't part of a big story, it probably isn't worth keeping."

If these are present, then the external (to the PCB) part of the PSU is simply a mains transformer giving 16V C/T and (probably) 16V). But if you don't have these regulators, let me know, and I'll try to figure out what is going on. -tony

Colossus (1944) was probably the first electronic computer. ENIAC (1946) was probably the first general-purpose electronic computer, while Colossus was built strictly to break a German cipher. Manchester/Harvard Mark 1 (1948) was probably first electronic stored-program computer. (ENIAC, though built in '46, was made stored-program in 1948, complicating matters somewhat) EDSAC (1949) is sometimes called the first full-scale operational stored-program computer. UNIVAC 1 (1952) was probably the first commercial computer. I haven't been able to find any citations of the first all-solid-state computer. Kai

Uh, actually, try October 1939... with the ABC. That's the Atanasoff - Berry Computer, which is now recognized as the first functional electronic computer. I posted 2 or 3 URL's for more info on the web, if there's a searchable archive of this list, check there for my post. If not, I'll look it up in mine if I still have it. BTW, you're timeline is still a bit off... IIRC John von Neumann invented the stored-program concept, didn't he? It was Markus & someone who designed the first UNIVAC mostly with concepts hijacked from the ABC... methinks it was in 1972 or so when the U.S. Patent office yanked the patent away from them and gave it back to Atanasoff & Berry.

I had a business meal tonight and after some discussion I found out that one of our guests is sort of into collecting old computers (basically he never got rid of any of the systems he's bought over time). One of the systems he mentioned he had was a Video Brain. Apparently this is a video game system. I *think* I vaguely remember hearing about this system. At any rate I'm curious about it and was wondering if anybody knew what it was as we both had too much tequila for him to describe and for me to comprehend it. I told him of my plans for the First Annual Vintage Computer Festival (which, by the way, is still on...I'm still in the planning phases) and he mentioned that he had close contacts with a show called The Computer Guys on the Discovery Channel and would arrange for me to meet with them to discuss possible coverage of the show.

Help with Apple Lisa 2

by kaikal＠MICROSOFT.com

Hi all, I just acquired a Lisa 2/10 and I'm trying to figure things out. The system starts to boot from the hard drive and comes up with a MacWorks/Sun Remarketing logo, then asks for a diskette. Looks like it's running MacWorks XL, is that correct? The system still has regular Lisa H/88 ROMs so it's not messed with hardware-wise. How come it wants a diskette and won't boot from the HD? I tried putting in a System 1 diskette from my Mac 128 and it gave me the "Welcome to Macintosh" splash and then died with a Sad Mac FE0002. Do I need a special Mac System version diskette to boot this sucker? Any info appreciated!! (anyone have a spare keyboard? I need a few keys) thanks Kai

by bluesky6＠ix.netcom.com

Does anyone know if one can still get Flex for the 6809 or 6800? There're people archiving and using CP/M stuff but it seems a waste to let a very simple and neat OS like Flex go the way of the dinosaur. Ben

Auction: Odds and Ends, Power Supplies, etc.

by gmast＠polymail.cpunix.calpoly.edu

I am still sorting through my stuff and have a few odd items up on the eBay auction. These type of things go pretty cheap (a buck for 3 power supplies and 4 RF adapters? Cheaper than the Goodwill!) but are sometimes hard to find (especially when you need one...power supplies?). Anyway, all you have to do is go to the link listed and check the price. Remember to figure shipping into what you want to pay. I'm in CA. Lot of Power supplies & RF Adapters (TI99/4A) Current bid: $1.00 Auction ends on: 07/03/97, 13:38:45 PDT http://www2.ebay.com/aw/itemfast.cgi?item=fpl6975 Indus GT Black Drive for Commodore 64 (photo) Current bid: $14.50 Auction ends on: 07/03/97, 13:50:38 PDT http://www2.ebay.com/aw/itemfast.cgi?item=mtr1454 Lot of 3 Joysticks (photo) Bidding starts at: $1.00 Auction ends on: 07/03/97, 13:57:24 PDT http://www2.ebay.com/aw/itemfast.cgi?item=hpq2180 Atari 800XL and Power Supply (No Workee?)

============================================================================= ClassicCmp - The Classic Computers Discussion List Part 3 in the ClassicCmp FAQ Trilogy Technical FAQ (Frequently Asked Questions) v1.6.1 Last Update: 7/01/97 ----------------------------------------------------------------------------- This FAQ is written with the primary purpose of making readily available answers to the more common questions appearing on ClassicCmp. It is Maintained by Bill Whitson <bill(a)booster.u.washington.edu>. The infor- mation in this document has been gathered from a variety of sources but, in general, the members of ClassicCmp should be credited for all contain- ed herein. I have, of course, endeavored to be as accurate as is possible and often failed ;). This FAQ is Part 3 of the ClassicCmp FAQ Trilogy. The information presented deals with regularly asked questions which are technical in nature. If you have questions, comments, or corrections (always welcome) please contact me at the address above. A current copy of this FAQ is available on the web at http://weber.u. washington.edu/~bcw/ccl.html or via anonymous FTP at 140.142.225.27 in the directory /pub/classiccmp/faqs as classiccmp.faq. ----------------------------------------------------------------------------- Updates: New Sections: 5.1 Updated Sections: 1.2, 2.4, 4.1, 5.1 ----------------------------------------------------------------------------- 1. General ------------------ 1.1 I just picked up a new machine. What should I do? 1.2 What's the best way to clean these dingy tan boxes? 2. Media -------- 2.1 What's a hard sector disk? What's a soft sector disk? 2.2 What's SS/SD, DS/DD, DS/QD, DS/HD, etc. 2.3 Can these formats be interchanged? 2.4 What disk sizes are there? 2.5 How do I take care of old media? 3. Component Failure Issues --------------------------- 3.1 Do EPROM's go bad? 3.2 How about ROM's, other chips? 3.3 How about capacitors? 3.4 Anything else? 3.5 So how do I backup all this stuff like you suggest? 4. Software ----------- 4.1 Where can I get a system disk for platform X? 4.2 What's the best way to back up my software? 5. Specific Problems/Solutions ------------------------------ 5.1 Is it possible to bypass an RF modulator to achieve composite output? ============================================================================= 1.1 I just picked up a new machine. What should I do? Don't power it up yet! All of the following should probably be done before that power switch gets flipped. Open the case - clean and visually inspect components. You're looking for traces of smoke, water, corrosion, loose screws, blown caps and resistors, cold (broken) solder joints, bent pins, etc. It may be a good idea to remove and re-seat all socketed components and connectors. If anything burned or overheated it will probably pay to replace it before powering up the unit. You can avoid a number of problems just by taking a peek inside. If you have the tools (and the machine is sufficiently rare) pull and dump backups of all EPROMs, ROMs, and PALs. If you have really cool tools (like a logic analyzer) it has been suggested that you use them to record critical information from those oh-so-hard-to-find custom chips. Specific information on how to do this is beyond the scope of a FAQ, but you probably know what you need to if you own the appropriate tools. Disconnect the power supply from the rest of the computer and start it up on a "dummy load". A six volt headlight bulb has been recommended as a convenient load. These should be available from any decent Volkswagen shop. Running the power supply without a load could result in damage to it. You may want to check the voltage output before you do this as it could be no where near the 5V average in micros. Even if you don't want to connect a load it's still probably a good idea to power it up separately from the computer for the first time. If you have a really rare beast it may be worth powering up some of the key capacitors out of circuit just to get them warmed up. Now you can power it up. Assuming it works, take a blank disk, format it, write some data to it, and read it back before using your precious software with it, as a bad disk drive could really ruin your day. 1.2 What's the best way to clean these dingy tan boxes? Cases: It seems best to start gently with such old equipment. Try soaking in a little water and dish soap and then scrubbing. This takes care of most jobs. For removing stickers try mineral oil or Goo-Gone (available at most hardware stores - in the US at least). If those don't work, acetone can be good but, if overused, can do more harm. For removing marker, almost any solvent is good (alcohol, naptha, etc) but will definitely discolor or dissolve plastic if not carefully applied. Lava soap is also good for removing marker but can smooth off textured plastic. For removing sun or tobacco discoloring a product called Purple Stuff available from auto parts stores (again, in the US at least) seems to do the job almost effortlessly. Recommended commercial products: Purple Stuff from Kragen [for discoloration] Brasso [ink/marker] (can discolor plastic) Antistatic Foam Cleaner from Electrolube [for discoloration/markings] Citra-Solv [for discoloration] (can dissolve plastic if undiluted) Cameo Copper Cleaner [ink/marker] Naptha [for stickers/goop/spooge] (very flammable) 3M GP Adhesive Remover [for stickers/goop/spooge] CRC 226 / CRC 556 [for stickers/goop/spooge] Fulcron [for discoloration] Blue Shower / BS II [for stickers/goop/spooge] Connectors: For edge connectors a plain pink eraser seems good for removing corrosion. Apparently other colors of eraser indicate a different texture - which may be damaging. Make sure to wipe the connectors with a clean cloth after erasing on them. There are a large number chemicals on the market that "magically" remove corrosion from components but as I don't know how safe they are, I'm not anxious to promote any of them. For pin style connectors a toothbrush and some softscrub or other mildly abrasive cleaner do wonders. Recommended commercial products: Electrolube contact cleaning sprays. Keyboards: I find a cycle through the dishwasher does a really nice job on keyboards. Just be sure they're completely dry before you put any power to them. If there is reason not to use a dishwasher (some key labels can come off) it is usually possible to remove each keycap and clean conventionally. [][][][][][][][][][] 2.1 What's a hard sectored disk? What's a soft sectored disk? We'll start with soft-sector since they're simpler to explain. On a soft-sector floppy disk the information that marks where a sector begins and ends is written to the disk by the computer (part of the formatting process). This means that various computers can use the same floppy disk types because the format of the disk is control- led by the operating system. Hard sector disks use a system of perforations in the media to mark the beginnings and ends of sectors. This means that computers which used hard sectored disks required the exact disk type they specified rather than a generic soft-sector floppy. A number of differently sectored disks were available - at least 10, 13, and 16 sector formats. 8 inch and 5.25 inch disks commonly used hard sectoring. 3.5 inch disks never came hard-sectored and, in fact, it would not be possible. 2.2 What's SS/SD, DS/DD, DS/QD, DS/HD, etc. These all refer to the number of useable sides on a disk and it's density (how "efficiently" the magnetic bits are pushed together). SS/SD is a Single Sided - Single Density disk, the earliest available type I believe. The storage afforded by a single density disk was very small compared to today's standards. Single Sided disks were popular because they were cheaper than DS and could be easily modified with a hole punch into double sided disks. SD was followed by Double Density which, amazingly, doubled the amount of storage space. Double Density was followed by the extremely short-lived Quad Density which doubled a DD disk. QD was short lived because High Density was right on it's heels and nearly doubled disk capacity again. DS/HD was as sophisticated as 5.25" disks became. 3.5" disks have progressed as far as DS/EHD double-sided / extra-high density. 2.3 Can these formats be interchanged? Well, that may depend on what computer you are using, but in general the following substitutions may be made: Desired Format Substitute --------------------------------------------------- Single Density Double Density Double Density none reliably Quad Density DD, HD (sometimes work, not advisable!) High Density none Other substitutions may be made, but due to physical differences in how the disks are made they are generally unreliable. It can almost be guaranteed that data written to a proper density disk of poor quality will last longer than data written to a good quality disk of the wrong density. In the case of quad density no substitution should be considered reliable. DD and HD disks both can be forced to work. One may work better than the other given the peculiarities of various drives. 2.4 What disk sizes are there? Disk Types? Physically? Standard Disks Unique/Proprietary Disks --------------------------------------------------------- 8" (Floppy) 5" (MiniFloppy) 5.25" (MiniFloppy) 3.25" (MicroFloppy) 3.5" (MicroFloppy) 3" (MicroFloppy) 2.5" 2" In addition to odd sizes - there is at least one type of disk which was physically different. "Twiggy" disks for the Apple Lisa 1 were regular 5.25" disks with the exception that they had two read/write windows. One was oriented "north" of the center hole, the other "south". 2.5 How do I take care of old media? Step one is Back It Up! After that, make sure it's kept in a clean, dry, temperature-controlled environment (I keep mine in a broken freezer). With disks it seems important to keep them standing on end rather than lying flat - the same goes for cassette tapes. I like to exercise disks and tapes at least once every six months although I have no real evidence that this has any positive effect. I have modified an old C64 floppy drive to simply spin when a disk is inserted and send large stacks of disks through it on a regular basis just to make sure they're not starting to stick up internally. An exciting and somewhat recent development is that availability of classic computer emulators that can make disk images of old media on PC's and Macs. This seems to be a very good way to backup disks since they will eventually go bad no matter how well we take care of them. The official line seems to be that floppy disks have a shelf-life of approximately 10 years. With proper care many are lasting a lot longer. [][][][][][][][][][] 3.1 Do EPROM's go bad? Definitely. They apparently are considered to reliably contain data for (on the outside edge) 15 years. This amount can be considerably reduced if, for example, the sticker over the window has dried out and fallen off. Luckily EPROMs were not used too extensively but they're out there. An EPROM writer/reader is a relatively cheap investment and an easy fix. Even if an EPROM has "forgotten" it's data it is still fine for being "re-educated". 3.2 How about ROMs and other chips? Things wear out. It's likely that even components which have not been fried by catastrophic failure will simply start to die someday. ROMs can be dumped to a file and re-written if they die. Other custom chips which are all too common in micros will be far more difficult to replace. The best advice is to stockpile these chips when you can - but someday even unused chips will probably start to turn up bad. In this case the best defense is to stockpile information in the hope of being able to modify an existing component to meet your needs. 3.3 How about capacitors? This seems to be another large concern, but rather than being an unreplaceable component a capacitor will take your unreplaceable components with it when it goes. It's a good idea to check out all the caps in a system if you haven't fired it up in a while. Caps go bad with time (even tantalum caps, apparently - although they are more reliable) and should be replaced if they are suspect. It's unlikely that it will be impossible to find a replacement capacitor as they are much more standard electronic components. 3.4 Anything else? Documentation: If there's anything which is entirely unreplaceable its the docs for uncommon equipment. Once they're gone, they're gone. I regularly pick up docs I find for equipment I don't have just because I may someday. Paper will, of course. go bad over time but it will be obvious and they will be easily duplicated. Hard Disks: ST-251s, ST-502s, MFM, RLL... old hard disks are going to go bad. Then they'll be gone. Theoretically, I suppose it's possible to crack a hard drive and replace a dead bearing, realign, relaminate, etc... but I've never heard of anyone doing these things in their base- ment. Perhaps in another 5 or 10 years many of us will be experts at this. 3.5 So, how do I back up all this stuff like you suggest? This answer will undoubtedly get longer as I learn more. The best ways seem to be to dump the particular ROM (or whatever) using the approp- riate equipment to a floppy disk (which most of this equipment allows).

Help! ============================================================================= 1.1 What is ClassicCmp? It's a mailing list for the discussion of classic computers. Topics center on collection, restoration, and operation. It is also an appropriate place for stories and reminiscences of classic computers. Lofty discussions dealing with the philosophical and/or metaphysical aspects of computers are often better handled in private e-mail. 1.2 Why is ClassicCmp? Uh, why not? There are lots of people who love these old machines and it seems like a fun idea to get together and talk about them. 1.3 What is a Classic Computer? _Any computer_ that has not been manufactured for 10 years is a classic. This definition is one I made up and it's entirely arbitrary. It seems to work OK, so I've kept it. 1.4 Who runs this thing? That would be me, Bill Whitson - email bcw(a)u.washington.edu. 1.5 How come I can never reach this so-called list operator? Sorry. It does often take me several days (sometimes weeks!) to respond to e-mail. I am often away for days at a time and when I'm not I'm still probably busy doing real work. I receive more than double the amount of mail that goes to the list in the form of spam, bounced messages, odd user requests, general bitching, etc. and I still have to filter out the messages I actually have to respond to, to remain employed ;). I will get back to you eventually. 1.6 Do you know you're just duplicating work other people have done. I get a "reinventing the wheel" e-mail at least once a week. If you show me another group of computer collectors that claims a membership as large as this one I'll show you a group that must be very hard to find. Obviously there are other groups of collectors and I'm cheering them on - I don't see a problem with duplicating and reduplicating lore that's quickly disappearing anyway. 1.7 How much mail should I expect to get on this list? The daily load varies widely from about 10 messages to over 100. Average seems to be about 44 messages a day. There are times where the message load peaks for as much as a week. [][][][][][][][][] 2.1 What can I talk about? Anything related to classic computers as defined above. There are many people on this list that really know what they're talking about, so you might want to check facts before you start shooting off messages. It's also a good idea to actually read the FAQs and check the archives a little before posting. 2.2 Can I talk about PCs? Yes. PCs which haven't been manufactured for 10 years. Even then, be aware that in many cases you would get a better response posting to PC newsgroups. 2.3 Can I talk about Minis/MainFrames/WorkStations/Gigantic Talking Boxes with Flashing Lights & Coundown Timers/Robots from Alien Civilizations? There has apparently been some misconception that this is a list for micros/home computers only. You'll note I said "misconception". 2.4 Can I post advertisements? Sure. As long as they're related to _classic_ computers. And, of course, use your brain - don't spam. Also, please state up-front whether or not you are willing to ship the items you sell outside your country as there are members of this list in a number of different countries. 2.5 Can I ask people to sell/give me their computers? Sure. But you're not likely to get a very nice response. Mine, for example, would be: Get your own f***ing computer! There are several people on usenet who will vouch for this. When someone posts about one of their machines without offering to sell it - it's really a pretty good bet that they're not secretly trolling for offers. See section 5 for info on how to find yourself a computer. 2.6 Can I ask for help fixing item x. Yes. Be aware that it may be difficult to help you fix things if you don't have much knowledge of how computers work or of how to use basic electronics tools (VOM/DMM, soldering iron, EPROM burner, etc). I'm no whiz with this stuff and the little knowledge I have has come from asking questions and then buying books to find out what "Simple... Just check the voltage on the caps in the PS to make sure one of them isn't flaking out!" exactly means. 2.7 Where can I look before posting a dumb question? It might be a good idea to take a look at what's available in the Archive section of the ClassicCmp web site (see below). 2.8 Can I type obscenities about Microsoft in ALL CAPS!?! (Or, in general, be unreasonable with reagard to advocacy posts?) Check your anti-MS baggage at the door, please. For that matter, drop any posts that serve only to perpetuate the holy wars. 2.9 Can I post trophy lists? Ahem. Er... I'm not going to go to the extent of banning this practise but it is considered bad manners. Don't whine to me because I used to be guilty of this and curbed myself ;). Post lists of newly acquired goods if you actually need info on them, not just to show off. 2.10 Can I use obscene language in my posts? Yes. Although I'm sure many people would prefer you did not. A number of people have complained about this. I'm not going to outlaw swearing - now that I've informed you that it bothers people you can make your choice. [][][][][][][][][][] 3.1 How many subscribers are there? Around 180 and changing daily. 3.2 How many subscribers use machine x? Check the web site (see below). The Classic Computer Encyclopedia shows the number of machines registered by subscribers. 3.3 Is this list archived? Yes. The archives are available on the FTP site (see below) in the directory /pub/classiccmp/archive. The file name format indicates the month/year of the archive. Keep in mind that they are quite large. [][][][][][][][][][] 4.1 Does ClassicCmp have a web site? Yep. http://weber.u.washington.edu/bcw/ccl.html 4.2 How come the web site is so ugly? How come a PET is so ugly? Who cares as long as it works? 4.3 Does ClassicCmp have an FTP site? Yes. Anonymous FTP at 140.142.225.27. Look in /pub/classiccmp. There's not much there that's not available on the web site. I'm starting to load old drivers and system disks on occasion. There is an incoming directory which subscribers may use for ClassicCmp-related file transfers if needed. [][][][][][][][][][] 5.1 Where can I find classic computers? The best places seem to be thrift stores and swap meets. These are closely followed by pawn shops and mom and pop computer stores. The holy grails are electronics scrap yards - but they tend to be wary of individual pick-and-choosers. Oh yeah - garage sales! 5.2 How much is machine x worth? Precisely as much as you'll pay for it. Oh, you're selling it? Then, precisely as much as I'll pay for it. Seriously, no one prices these any more. I have an old Computer Blue Book that lists many classic computers but the prices are just ridiculous. Some machines (Apple Lisa's, old old Mini's, and unreleased prototypes) are starting down the road toward their original selling prices but it's unlikely that most will ever be worth more than the cost of their components. 5.3 Will 1000's of innocent machines be scrapped if I don't save them? Yes. This is the impetus behind every collector's tireless and selfless effort. Each machine we fail to save has it's gold parts mercilessly hacked off and sold (just like rhino horns - and look at the rhinos). The remainder is then sent to China to be made into bicycle spokes (you probably think I'm joking). Save a computer! Act now! Remind your SO of the rhino and cuter, fuzzier animals. It might work. In all seriousness - there are a large (and growing) number of so called "computer and electronics 'recyclers'" who take usable computers and recycle them into "reusable scrap". Small amounts of gold, silver, and platinum are extracted and the remainder of the material is generally just marketed to less wasteful countries. 5.4 I don't understand anything. Help! Don't worry - you're not the only one. Reading this list, old magazines, books and whatever else you can get your hands on is the first step. Once you reach a critical mass of knowledge thigs get a lot easier. I'm working on putting together a list of books and tools that a beginner should get his hands on. If you have suggestions, let me know. =============================================================================

If I rode a bicycle, and had a penny-farthing, I might well use it, yes. Please give me one _good_ reason not to. While I can think of other things that would be a good as the MK-14 for (say) I2C chip testing (a microcontroller board springs to mind), I can't think of anything that would be _better_. The origianl statement stands. I can't think of a single computer system (owned by me or not) that can't be used for useful work in 1997. The fact that it's old has nothing to do with it. I can think of many applications that need fast machines with plenty of memory. I'd not use (most) classic computers for those. But as I rarely need to do such work, I see no reason _not_ to use a classic. > > enrico -tony

who's on first?

. > seems to be the fact that they were electronic and the idea > of electronic counters (which is most of what ENIAC was) had This is fairly complete history of electronic computings origins however there were several electric (relay logic) designs not mentioned here. While slow they capitialized on the then fairly mature telephone realys of varying design. They were generally of two types the contactor or n-pole double throw or the stepping(counting) with typically 11 positions. The later could be used to make counters or registers. In the early years (pre about '44) these were used to make calculator type machines of the programmed or fixed type. Allison

Strange Tandy 1000HX

by jeffh＠unix.aardvarkol.com

I've just arranged for a Tandy 1000HX and it appears to be kind of odd. It was bought at one of Tandy's infamous 'tent sales' where they dispose of stuff they've had sitting around the local 'Shack, and the guy who bought it originally said that it didn't come with any 3-1/2" floppy installed and that both covers are still over the bays. It boots off of an external 5-1/4" drive, which if I remember correctly, is selectable easily enough by way of the SETUPHX program included with it's DOS diskettes. Do any of you TRS-80/Tandy knowledgable people remember ever seeing a HX set up like this? Every one of them I've ever seen new has come with a 3-1/2" floppy in the left-most bay, right next to the expansion connectors. I bought one of these nifty machines when they first appeared as well, and had an external 5-1/4" floppy and CM-11 monitor with it, as well as the PLUS memory, RS232 and 1200 bps modem cards.

Perhaps you could explain _why_ I can't use one today. I've written many, many embedded control programs (monitor some inputs, update state variables, toggle outputs, etc) that would _trivially_ fit into 256 bytes of SC/MP code. If I add the optional INS8154 RAM/IO chip I have another 128 bytes of RAM and 16 bidirectional I/O lines. I can also add another 256 bytes by raiding my junk box for some 2111's. I can think of a few dozen applications that I could use that for. A trivial one is an I2C chip tester - replace the monitor ROMs with ones burnt to contain the correct code (avoids using the cassette interface option...), and have said code read I2C addresses/data from the hex keypad and bit-bang the I2C protocol on a couple of the 8154 lines. Or, how about a Centronics printer tester (emulate the centronics port on the 8154, make it print the classic scrolling ASCII text). Or a programmable pulse generator for digital IC testing. Or a hundred-and-one other applications. Yes, I can do any of those with a PC or many, many other machines. But the MK14 is small and portable. It doesn't need a monitor. It will start the program instantly at switch-on. It is still useful today. > > enrico > > -tony >

'Home' computer: Definition

by jpero＠mail.cgo.wave.ca

Hey, that mailing list fudged part of my first line as their command which reported in error and refused to post it here. :( Q. Hold on, I would like to express my opinions... "Home Computer" term is invented by corporations to supposely help define their markets and totally miss it all the time because users needs is usually higher than their corporates' computers by factor of 1.5 to 2. At same time tries to pull off a coup on "home" users by selling stripped down with loads of cut corners and oft-nonstandard parts machine at horrible prices. Case in point: PCjr. PCjr and orignal 2 piece PS/1 (sold at 1000 bux cdn but you get no HD in it, introduced 1990's but users right away dumped them by pallets barely 2 years after. Yuk!) Side note: I traded few things to get this PS/1 2011 and used it for a while but sold it cheaply to a user who have modest needs than I. (for me, I can't manage well without hard drive attached even all the down to XT but not for apple II's their floppy drive is very fast enough to forgo hd, very impressed but at that time too expensive for my taste but now they are so cheap now.) So there was a bad taste to this name "home computers" in general. Similar types of computers did well in many areas but happened to lack important areas that killed it. Ironically, better to build DIY similar capablies 386, 80mb, 1mb, desktop/mono vga and still easily interchangable than that darned PS/1 2011 models. When I read about many machines and few "home computers" as called toys but I was mistaken when I saw and heard that "toy", boy, they're mistaken and I was taken too for a while! Indeed they were used for anything within their capablies so I accept anything that has CPU in it at same time useful and expandable should be decent computers, no more or less. :) C64, PET's, apples and such has just right stuff to keep users happy. In closing, corporations always underestimate "home" users. But now they are not pushing this word and crippled machines anymore, now selling them in general to any users execpt for corporations who needs turnkey system just to do very specific jobs like weak machine strictly for WP use, alphas for servers and heavy graphics, fast processor for programming but that is getting blurred that most users can afford them and can put them in their homes. Ok, now I could respond to yours... :) > I've seen a couple of posts in here that declare, in very firm terms > indeed, that machines like the MicroVAX and PDP's are not "home" computers. Suppose, Digital did not cared a whit and cut prices on that and we would be sure many would have one in home if they're small enough and easy on power requirements. Linux is there now and NT can be run on alphas but bit late and cost is fast appoaching to affordable levels where getting a pentium pro machine is not only option. > > For the sake of discussion in this list, and computer hobbyists in > general, I would like the world to know that I define 'home computer' as > any machine that you can: > > * Comfortably fit through your door... > > * Doesn't test the load limits of your target floor... > > * Power and run without tripping your main breaker... > > * (most importantly) Have fun restoring and working with... in your home! > > Which just goes to show that such terminology is so relative, there's > little point in debating it.

I've seen a couple of posts in here that declare, in very firm terms indeed, that machines like the MicroVAX and PDP's are not "home" computers. For the sake of discussion in this list, and computer hobbyists in general, I would like the world to know that I define 'home computer' as any machine that you can: * Comfortably fit through your door... * Doesn't test the load limits of your target floor... * Power and run without tripping your main breaker... * (most importantly) Have fun restoring and working with... in your home! Which just goes to show that such terminology is so relative, there's little point in debating it. Why waste the bandwidth over something as trivial as a difference in wording?

Well, no. I pulled a CCS catalog (dated Feb 1981) and took a look, and the only 28xx card was the 2810 Z80 CPU. As I read the catalog, though, I might expect 28xx to mean some sort of processor or coprocessor. Or maybe not; CCS weren't entirely consistent with their numbering scheme and the sample sizes weren't that large. -Frank McConnell

actually, ive heard the plural for unix to be unices, rather than unixen, or also expressed as *nix, for the different flavours of unix out there. the hacker's dictionary is great though, just to read the words and their origins. i've now got everyone at work to use the term "virtual friday" which i picked out of the dictionary! =D << > Is VAXen the plural of VAX ? Why? Play on words. Like the plural of 'Ox' is 'Oxen', plurals of many things involving computers that end in 'x' end in 'xen'. As VAXen, Unixen (for the many variations on the Unix OS such as Venix, Linux, BSD, Solaris, AIX, Xenix, and several others. You'll also see more than one box (as in CPU) referred to as 'boxen'.

> Is VAXen the plural of VAX ? Why? hobson's choice, it just is. For some reason VAXes never caught in some circles especally when you dealing with SMP and clusters of vaxen. There are many stories why, most I've forgotten though as a millrat I should be up on it. Actually there are some good stories about node names on the DIGIAL network. My favorites were MILRAT, and the other two cluster members MILROT and MILDEW. They were apt names for vaxen located where straight down through the floor meant you were in the pond. Allison

Weekend Additions

by rcini＠msn.com

David: You can still get Tandy/RS software directly from their National Parts service. Last year when I acquired a Model 100 system, I needed the DVI (disk-video interface) diskette, I called them. The price: $5 each. I can't seem to find the telephone number (it is an 800#, though), but it's called "Tandy Consumer Mail Center". You should be able to get the number from your local R/S. Give them the catalog# and what you're looking for. They will probably refer you to the Tandy Software Service Center, where you can order the diskette. ------------------------ Rich Cini/WUGNET - ClubWin Charter Member (6) - MCPS Windows 95/Networking ======================= Date: Sat, 28 Jun 1997 10:13:11 -0400 (EDT) From: SUPRDAVE(a)aol.com To: classiccmp(a)u.washington.edu Subject: weekend additions Message-ID: <970628101309_408583751(a)emout07.mail.aol.com> i need some help on what i found this weekend. a trs80 model III 48k. came with trsdos disk, but i havent tested it yet. can anyone point to a source of software. now i need a model ][ to fill in the blanks!

ROM Archive

by rcini＠msn.com

Sam and William: Here's what I think so far (which isn't much <g>): 1. Record format: open (depending on software for EPROM programmer); S-records, Intel Hex, binary. 2. Submission & storage: UUEncoded image file e-mailed to "repository"; ROM/EPROM chips sent by snail mail and returned. All submissions should have as much info about the source computer as possible (board revisions, date of mnaufacture, etc.) 3. Requests & withdrawls: by e-mail to those with programmers; by mail for those supplying their own chips; e-mail request with no chip sent. 4. Cost: nominal (cost of postage and EPROM). How does this sound so far?? ------------------------ Rich Cini/WUGNET - ClubWin Charter Member (6) - MCPS Windows 95/Networking ------------------------------ What format would these images be?

What I'd pointed out before is many of the PDP-11s were in the same space and competing for the same percieved market as the PC. While some -11s were large like the 11/70 with RP06/7 disks and wanting a cooled computer room. most were at must one rack and a disk systems that were more modest in size. The systems I refered to as desktop were: LSI-11/03 (floppy based in short rack 28" tall) PDP-11/23+ (in 40" tall rack with RL02 removeable disk and floppy) PDT-11/130 (slow tape but it was only vt100 sized!) PDT-11/150 (Late 70s early 80s) not large at all. (also called breadbox) PRO350 and later 380 Microvax I/II (ba23 pedestal) VS2000 (box slightly larger than DECMATEIII) VS3100 (aka pizza box) These happen to be DEC systems but IBM, HP, DG were all out there too with desktop sized or desk side minies in disgusise. All very collectable and also useable! Allison

I am not a billy gates follower. I despise his efforts and his software. and winsucks 95 is a laugh!!<G> but the issue is machines, and if you run Linux, as I do, that pentium will spring to life! so the PC is not the greatest machine, but if you run software that was properly written, (i.e. not from microsuck) you get fantastic results, that is why I like my commodore 64, it can do alot on 1 MHZ. >'Realistic games'.

But Realaudio is a standard, but it is an INTERNET standard for sending LIVE SOUND from any web server. it has many uses, and the fun part of it is that I live in Indiana, and when I lived in St Petersburg FL, there was a good radio station there that I loved, and through Realaudio I can now listen to it here. and this is not just for PC's, it runs on MACs, UNIX Linux, and most Sun machines. >we had good quality audio on PDP11's (thanks to a little board from 3RCC) >in 1976.

I have some software for the C=64 that plays back digital sound files. with the stock 64K of ram, I can hold a 6 second clip. with the 1764 ram expansion with 512K of ram, I can hold a 60 second clip, but no longer than that. >What I'd be missing by going to a modern machine would be : >Documentation.

They just don't exist I programmed in BASIC, and that is fun, and I tried 6502 assembler, and almost had a working interrupt handler going, but my brain fried, the opcodes are easy, but remembering memory addresses when deprived of caffeine is hard! the interrupt handler was for a terminal program that I was writing that utilized a 6551 UART in a commodore 64. I love hacking old hardware! and it also had interupt driven multitasking, as in this terminal, you can use the modem and play .sid music files at the same time! that was fun!! now I program in C, and if you do it right, you can make any machine dance to your beat. >for most modern machines >Repairability. I can fix classic computers with no problem at all.

And don't tell me to >replace the motherboard - if the PC is a few years old I'd probably have >to replace the CPU and memory as well. that is just the ticket. A brand new 486 motherboard cost $90. with it you get real functionality. I know some who will pay twice that for a doorstop... actually, you can get a decent modern PC together just by scrounging computer shows and bargaining for parts. assembling a system from scratch with old parts is very fun and rewarding. and the reliablity rate for modern chips is very high. in fact the monitor or hard disk probably will die before the motherboard will. also I am speaking of those who NEVER touched anything new, and passing judgment. if you tried the new stuff, and hate it, that is fine, but I can't stand those who never tried it then saying it sux.

Error Condition Re: Re: 'Home' computer: Definition

by jpero＠mail.cgo.wave.ca

Subject: Home computer: Definition My opinions and to disgress; "Home Computer" term is invented by corporations to supposely help define their markets and totally miss it all the time because users needs is usually higher than their corporates' computers by factor of 1.5 to 2. At same time tries to pull off a coup on "home" users by selling stripped down with loads of cut corners and oft-nonstandard parts machine at horrible prices. Case in point: PCjr. PCjr and orignal 2 piece PS/1 (sold at 1000 bux cdn but you get no HD in it, introduced 1990's but users right away dumped them by pallets barely 2 years after. Yuk!) Side note: I traded few things to get this PS/1 2011 and used it for a while but sold it cheaply to a user who have modest needs than I. (for me, I can't manage well without hard drive attached even all the down to XT but not for apple II's their floppy drive is very fast enough to forgo hd, very impressed but at that time too expensive for my taste but now they are so cheap now.) So there was a bad taste to this name "home computers" in general. Similar types of computers did well in many areas but happened to lack important areas that killed it. Ironically, better to build DIY similar capablies 386, 80mb, 1mb, desktop/mono vga and still easily interchangable than that darned PS/1 2011 models. When I read about many machines and few "home computers" as called toys but I was mistaken when I saw and heard that "toy", boy, they're mistaken and I was taken too for a while! Indeed they were used for anything within their capablies so I accept anything that has CPU in it at same time useful and expandable should be decent computers, no more or less. :) C64, PET's, apples and such has just right stuff to keep users happy. In closing, corporations always underestimate "home" users. But now they are not pushing this word and crippled machines anymore, now selling them in general to any users execpt for corporations who needs turnkey system just to do very specific jobs like weak machine strictly for WP use, alphas for servers and heavy graphics, fast processor for programming but that is getting blurred that most users can afford them and can put them in their homes. Ok, now I could respond to yours... :) > I've seen a couple of posts in here that declare, in very firm terms > indeed, that machines like the MicroVAX and PDP's are not "home" computers. Suppose, Digital did not cared a whit and cut prices on that and we would be sure many would have one in home if they're small enough and easy on power requirements. Linux is there now and NT can be run on alphas but bit late and cost is fast appoaching to affordable levels where getting a pentium pro machine is not only option. > > For the sake of discussion in this list, and computer hobbyists in > general, I would like the world to know that I define 'home computer' as > any machine that you can: > > * Comfortably fit through your door... > > * Doesn't test the load limits of your target floor... > > * Power and run without tripping your main breaker... > > * (most importantly) Have fun restoring and working with... in your home! > > Which just goes to show that such terminology is so relative, there's > little point in debating it.

Interesting S100 boards

by dastar＠crl.com

I just discovered some *VERY* interesting S100 boards that I didn't realize I had in my box 'o S-100 boards. They seem to be some kind of Atari development/prototyping system. The boards are: 65xx Emulator, part no. 100-015-2, (c) 1983 Atari [this is the PCB only] Trace Memory Interface, part no, 100-003-2, (c) 1983 Atari 6502 Processor, part no. 100-003-2, has a 6502 and some other stuff, such as a clock speed DIP switch (1, 2, 4 MHZ settings), some RAM, a couple ribbon cable connectors. I have 2 of these boards but one is incomplete (does not have all the chips the other one does). All have the Atari name and logo and a copyright date of 1983. Also have these: the Encryptor, Jones Futura Corporation, Model ENC 100-1 California Computer Systems, Model 2832 [has this big, black 3"x3" square and 3/8" thick block of resin on it, have no idea what it's hiding] Any idea what this stuff is?

I have a thing called a 'modem maximiser' (a serial port data buffer box with a real time clock, parallel printer port, etc) that has an optional encryption unit. It too was a potted module. As I had a few spare modules I cut one apart and found it contained an 8032 (I think) microcontroller, RAM, a ROM (I must desolder that and examine it) and a TTL latch. Pretty much what you'd expect - a little microcontroller that reads in data, encrypts it, and sends it out again. > > Any idea what this stuff is? > > > Sam -tony

ROM Archive

Sam: > 1. Record format: open (depending on software for EPROM programmer); S-records, Intel Hex, binary. >> I'm no expert at this so I'll defer. The various hex records are ASCII representations, so I figured that they can be transferred with no problem by e-mail. If we're doing ftp, it doesn't matter > 2. Submission & storage: UUEncoded image file e-mailed to "repository"; ROM/EPROM chips sent by snail mail and returned. All submissions should have as much info about the source computer as possible (board revisions, date of manufacture, etc.) >>Sounds good. The repository then is a "soft" repository of ROM images? Yes. This way, we can transfer it, or burn it. > 3. Requests & withdrawls: by e-mail to those with programmers; by mail for those supplying their own chips; e-mail request with no chip sent. >> I assumed since the images are merely files they could be downloaded by anyone requesting them. Is the repository also going to have physical EPROMS that someone can request? If so, why? THe only reason to have EPROMs available is for those who are incapable of burning EPROMs them selves. > 4. Cost: nominal (cost of postage and EPROM). >> Is the repository also going to be in the business of supplying people with pre-burnt EPROMS? If so then 3 makes more sense now. Sure, why not. I don't think that there will be a huge demand, so the repository will not keep pre-burned ROMs on hand. ------------------------ Rich Cini/WUGNET - ClubWin Charter Member (6) - MCPS Windows 95/Networking

Computer Trivia Game

However, the game I was thinking of was one that had cards and (I think) a board, like trivpursuit. (I know my brother actually won a copy at the West Coast Computer Faire, but he's an a$$h@le and we aren't in contact.) --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

Lisa's scores

An awful lot of people have painted pictures of pretty women... Still, there's only one Mona Lisa. Sometimes it just takes a slight modification to turn the ordinary into the extraordinary. I still say the Lisa gets an out-of-the-park home run on aesthetics. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)crl.com that none but madmen know."

Modern Apps on Old Machines

Alternatively I could just pick up one of about 30 PDP11 manuals I have lying about and not only see a picture of the outsides, but also see board layouts, schematics, timing charts, microcode flowcharts, and other useful info I've never found pictures of the outside of computers to be particularly interesting. The useful diagrams (see above) are just as useful on a 1-bit- per-pixel display. > >3.

The display is a clone Hercules card driving that Zenith monitor with the 'interesting' PSU. After I fixed the PSU and tweaked the internal controls, I have an image _for text_ that's as sharp as any cheap SVGA monitor I've ever seen. No eyestrain at all. If you want colour, look at an old Barco (or Fimi, Philips, etc) monitor. Some of those are very well focused and converged. > is worth it becuse it prevents eyestrain, and you can use your system for > longer amounts of time. I used color TV's before when I got started, and > serious word processing was painful to the eyes. RGB's are better, but not RGB simply means that the video signal is sent along 3 separate cables for the 3 primary colours. Technically a VGA or SVGA monitor is an RGB monitor. > all in all, if the machine you use now does all what you want, thats great! > but the day WILL come where you just need to have a feature that you have In which case I'll do what I've always done in the past when this happens.

Video game machine/Computer With 6800 Processor

by bluesky6＠ix.netcom.com

Does anyone remember this machine : it's a video game console (like the atari VCS) but which could sit on a box which then converts it to a home computer. The machine ran on a 6800 and had built-in basic. It came out approx at the same time as the Atari 400/800 series (78-79?) I remember seeing an ad on it and the heading of the ad was "imagination machine". Ben
