The SLM804 Laser Printer was Tramiel's attempt at a laser-for-the-masses back when a Laser Printer was a multi-thousand-dollar item. It had no on-board intelligence or memory; it used the ST's CPU/RAM. Sounds like what you have there is the controller interface. (Plugs into the ACSI port on one end and the printer on the other.) P.S., anyone want an SLM804 in need of some repair? --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

IMSAI 8080

by peacock＠simconv.com

> Yes, I wonder how many of these 'collectable' computers > are in any sense being preserved properly. I would doubt > if ROMs were ever backed up or PSUs tested. Hmm, IMSAI's didn't have ROMs (or PALs and FPGAs, programmable logic had yet to be invented), unless you added them in yourself. As for checking the power supply, an IMSAI was extremely easy to eyeball...huge transformer, diodes, and beer can size capacitors. One problem I never had with IMSAIs was in the power supply, the design was right out of Electronics 101, nothing beats a big lump of iron for simplicity. Now rust might be a problem... Actually, the only real problem I've ever found with S-100s is the bus connectors wearing out. I have an old Ithaca Intersystems DPS-1 in need of a replacement Morrow motherboard. Well, not really in a hurry to fix it, all the Ithaca boards have been in the IMSAI for the last 10 years, but I hate to throw out the DPS-1 since it had the neat front panel with the PDP style toggle switches.

MicroVAX 2000

by peacock＠simconv.com

> This one is a Model 625NT-AA, and comes without harddisk. It appears that there is a resistor board installed to provide a load comparable to the drive on the power supply. According to a rather sketchy spec sheet that I d/l'd from DEC, it can handle a maximum 318mb local disk. Based on the 53C80 chip installed, I presume that the drive should be SCSI. > Not exactly, the SCSI port is only for a tape drive, a TK50Z (an early ancestor to modern DLT drives). A uVAX 2000 uses MFM drives, either a Microplis 1325/DEC RD53 (70MB) or a Maxtor 2190/DEC RD54 (159MB). In order to load VMS you really need the RD54, 70MB is too small. The HD controller is the 40 pin SMC chip on the motherboard. Oddball MFM format, not compatible with WD HDCs, but the 2000 has a formatter in the ROM. The 318MB figure comes from using two RD54 drives (159 each). > At the rear of the machine are three sub-D connectors, one each 25-pin, 15-pin, and 9-pin. What are their functions? The 15 and 9 are presently encumbered by a plugin box that has three RJ45(?) connectors. Network link? > The 25 pin is the TTA2 port, RS423 (close to RS232) with full modem support (sort of). The 9 pin is TTA3:, another RS423 serial port for a local printer or terminal, but not wiored like a PC 9 pin serial. The 15 pin is for a workstation cable and carries the video (the coax connector on the little box), plus a keyboard and mouse connector (TTA0: and TTA1: serial ports). They are not RJ45s. You should also have a BNC coax connector for 10Base5 thinwire ethernet. For more info check the comp.os.vms and comp.sys.dec newsgroups, they have lots of FAQs for uVAX 2000s. I don't know the URLs but if you post a question on one of the ngs they will direct you to the web page. BTW, I might have an expansion memory board left for a uvax 2000, i'll check the old DEC scrap box. IIRC it brings one up to either 8 or 14MB of RAM. (a uVAX II maxes out at 16MB of RAM) Jack Peacock

More fun stuff picked up this weekend: Canon Cat - A glorified word processor that was created by one of the original members of the Macintosh team. Mentor Graphics badged Apollo DN300 workstation. Whole box of Apple II cards and other misc stuff. Anyone have any info the the Canon Cat? Or manuals/software for the Apollo? Oh, I also have a couple of AT&T 6300 cpu's that I'll give to anyone who wants them (don't know if they work, don't have time to check them out). I also have a AT&T 3B2-310 with external expansion unit (XM something or other) for sale or trade, make me an offer I can't refuse :) BTW I'm in Austin, TX. George

Intelus/NEC laptop

by gpine＠gri.org

I recently acquired a laptop that appears to be an NEC PC-8201 with a label of a company named Intelus on the front where the PC-8201 label would be. There is also a serial number label on the back that lists the address of Intelus as in Rockville, Maryland. In addition, it has a miniature connector labeled phone on the back in place of the second SIO connector (maybe the unit has an internal modem? I haven't opened it up to check), and it has an additional small removable panel on the back that provides access to an edge-card connector on the motherboard. My machine has nothing plugged into this connector. The machine fires up showing BASIC, TELCOM, and TEXT programs in ROM, and the BASIC program even says PC-8201 Basic, verson 1.1. The machine is in all other respects (keyboard, display, battery pack, ROM access, and external connectors) identical to my PC-8201. Is anyone familiar with this machine?

The first mass-produced calculating machine was Thomas > de Colmar's "Arithmometer" in 1820. Good point. Many early clocks were (or contained) primitive analogue computers, so I think you win there... sort of. Two books to look at: "The Mediaeval Machine" by J. Gimpel and "A History of Engineering in Classical and Mediaeval Times" by D. R. Hill. Gimpel will fill several holes in your timeline - Su Sung made quite a complicated astronomical clock in c. 1090; the middle ages saw a sizeable crop of similar machines in the west, culminating in that of Giovanni Dondi, under development from 1348 until 1364. Hill's treatment of clocks is also interesting. He points out that the Classical civilisations had (presumably inherited from the ancients) a system by which the hour changed in length depending on the date so that sunrise to sunset was always twelve hours. Thus ordinary timekeeping clocks had to combine time and date in an analogue computer to get hour-number out at the end. Some of the mechanisms Hill describes get this quite wrong! (I don't recall any of these clocks also taking account of lattitude...) OK. I'll go for the Z1 as the first _general purpose_ computer. Philip.

9 TRK Drives, Oz, Driving

by jpl15＠netcom.com

Hello List::::: I am looking for one or two 'real' DEC 9 trk tape drives w/formatter cards, in the SoCal area... TU16 and the like, and one of the small 7" reel jobs whose model number escapes me just now. I am willing to pay moderate sums for known-good-working units. Also looking for a *complete* 11/750 system... (computer, drives, tape unit, console, docs[ha!], etc.). I have a very old 11/15 to sell/trade, and several Plessey clone devices, including two CDC Caelus drives w/interface cards and engineering docs.... I can deliver in the General SoCal area. Note to Down Under Listmembers: I will be travelling to Sydney on the 2nd of July, and then caravanning to Adelaide over the space of about 10 days. It would be cool to meet some of my fellow collectors while I'm in your quadrant of the globe. E-mail me privately if there's any interest.... esp. Huw Davies, it would be fun to thank you in person for the help with my RK05 odyssey... ;} Driving: The farthest I've gone to 'rescue' PDP stuff was Los Angeles to Seattle and back in three days... 2200 miles. It was truly fun to be out on the Road away from work, phones, e-mail, faxes, memos, interruptions... thanks again to Bruce Lane for providing the excuse.. :o Oh, yeah... anyone have a Kennedy 9300 cheap/trade/free? I need some Parts...... Cheers John

Help! RA82, etc.

by kyrrin＠jps.net

OK... I've got a MicroVAX II almost ready to go. However, I'm handicapped by my lack of any documentation for the RA82 disk drive. The problem: When spun up, even when connected to the KDA50 controller, the drive gets up to speed, seeks a couple of times, and then lights 'Fault.' I'll press the 'Fault' button to try and reset. On the first press, 'Run/Stop' and 'Write Protect' flash. On the second press, it goes through its seek-and-fault cycle again. My question: Do I even have the thing wired right? Could someone familiar with this stuff describe to me which cable goes where, just to make sure I'm not hallucinating? The controller seems OK. It passes its internal and service diagnostics, and when I stare at the LEDs on the two boards long enough I can see some sort of fast scanning sequence going on about every 5-7 seconds. I can, if need be, open up the RA82 and see which internal LEDs come up. Any and all help appreciated. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

Recent Commodore finds...

by foxnhare＠goldrush.com

What a surprising day, went to the Stockton Delta College Flea Market (in California) and found a couple goodies... First I bought an SX-64 keyboard and C-128 in the $1.00 section of someones space. I bought the SX keyboard cause I have a second (dead) SX without one the 128 was because I felt sorry for them having to break a 20 (also I figured if it was dead I could use its keyboard with that keyboardless 128D I have). After wandering a bit my wife shows up with a keyboardless SX-64 also from the same booth's dollar section, what a wonderful woman! (I must've missed that SX, better have my eyes checked!). Anyway $3.00 spent and get home to discover the 128 works (missing the F3 key) and the SX has some issues but seems functional (does not boot to BASIC, just a black screen, but does run carts ok, probably bad BASIC/KERNEL ROMs also keyboard connector/curcuitry needs work too.) So far I have bought 3 128s (real cheap) with the plan to use the (supposed dead 128's) keyboard on the D to discover it was not even a dead machine after all. Well Sam, (who finds many a dead Commodore 8-bit) I guess Commodore spirits aren't with you. :) Almost was tempted to buy a few of someone else's Mac problems (nice seller, he told the truth on all of em), but I figured I'd play it smart (this time). -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

But if you <implemented the same logic with relays and redesigned it, the result <would be possibly useable. Logic design with realys have different implmentations as a bistable with gates can be one relay. Stepping relays are inherent counters and can be made to count to any amount. I've used realy logic for machine control, operating speed 2 to 5 sec per interation so fast was not a required thing. Doing sequential work using relays and switches is really fun. Of course all that drove air valves so there was air logic too. ;) Oh, and you can do logic with air valves, air one shots, even flipflops.

Sun 3/50

by maxeskin＠hotmail.com

My visit to the MIT Flea today was unproductive. But, so it wouldn't be wasted, I grabbed a Sun 3/50 for $1. It seems to work, and is in good condition. I looked at the board, it has a 68020. Can someone tell me more? Also, how do I hook it up to a terminal? Which pins do I need? I plugged my Mac in, but it didn't show anything. My Mac serial cable only has pins 2,3,6,7,8, and 21. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

HP 85

Megan - > I just wanted to find out if people on this list think that $100 for > an HP85 with printer and tape drive is a fair price. I'd have to say probably not. I have a pair of HP-85s that I snagged in the last 18 months. One cost me $1.00 at a private school flea market and the other cost $12.50 at an auction run by Goodwill. The system from Goodwill included an HP padded travel case -- in fact, the system was originally stacked with some luggage and had not been bought during that portion of the auction. I found out after I pointed the system out to the auctioneer and bought it when they auctioned off the rest of the computer stuff (usually C64s, Atari, and the occasional Apple IIc or Mac Plus) that I could have simple asked for a "no bid" sale for the last bid price in the luggage area and gotten the system for $3.50. -- Tony Eros NSIS - ENS/Internet Wilmington, DE -----Original Message----- From: mbg(a)world.std.com [SMTP:mbg@world.std.com] Sent: Sunday, June 21, 1998 1:35 PM To: Discussion re-collecting of classic computers Subject: HP 85 I just wanted to find out if people on this list think that $100 for an HP85 with printer and tape drive is a fair price.

Of course, the CoCo does have a little stuff hanging off of the two PIA's that isn't given in that data sheet. But I'd be surprised if they had gone to Commodore for that. Of course, I'm surprised enough at the patent on the case (who would need to infringe a patent to make a rectanguloid plastic box?!), so I guess the origin of the remainder of the circuit design could surprise me too...

Ok, the 2002 wouldn't be exactly the machine for continous display in action, but even if it is just as static display, this one time running test ist the best verification that the static display is _complete_. (In fact, the critical part of the 2002 is the storage drum - even back in time when it was new, every power up and down had to be guarded by tecnicans - hmm but even here, since the drum is a closed device, one could replace it (invisible) by a modern electronic emulation... just thinking) Gruss H. -- Ich denke, also bin ich, also gut HRK

What is the first computer?

by allisonp＠world.std.com

<Yes, relays are a lot slower than electronic devices, and yes, they may <be less reliable. But they're not as slow as all that. They are reliable, especially the sealed ones...saves extracting bugs(moths) with tweezers(aka: Lt Hopper). Speed; the problem is cascade. I've worked with relay trees of good size and while each can do 10s of repetitions persecond tens of them in cascade can only complete one cycle in a second. To do logic like a counter using relays is slow even though the individual relays may be fairly fast. Though using s stepper relay is faster than chained relays. Allison

Woooooosh - Your 'record' machine was just bypassed by a 1941 Zuse build from junk telephone relais. According to Zuse a multiplication took 3 seconds. A Multiply nedded 16 Machine cycls and 16/3 equals to 5.33 Hz - just - 5 times faster - calculated on cycles, but one cyle had 5 stages. Satge 1 to 3 where used for execution, while 4 and 5 are used for load and fetch - the operation fetch ocuresd simultaniously to the store. So even this early had paralell working units (didn't tried Intel to tell us that this was one of the big inventions of the Pentium - you know the processor with all the little rainbow coloured man inside instead of the usual LGM) Althrough the speed was something like 5 or 6 Hz, it is legal to speak about a clock speed of 15 to 18 Hz when comparing to newer machines. And for relay speed itself - 40 to 100 (controlled) switchings per second have been possible for pre war relais and EMS relais (technique of the 60s) are able to do up to 1500 Hz - we tried it 20 years back :) Gruss H. -- Ich denke, also bin ich, also gut HRK

First personal storage media...

Sorry about the white space, I'm using Lynx, as always... I agree with that! I've taken two sets of disks for Mac System 7 from a Mac Lab, and both had bad disks.

fire control computers?

I recall being one of the first at the college I worked at then, to own floppies. I remember the price was a few pounds each around 1980, and one local supplier sold them to students one at a time. Unfortunately (for the dealer) not all the staff realised the price was per floppy, not per box-of-10, and a few of us reaped the benefit of that. I still use some of those disks in an Apple ][. > New Topic! Ok people: what sort of storage media (and for what system) did > you guys carry around to start out with? Most of my early computing was done on machines that used punched cards or paper tape, but I didn't often get to keep the cards, and sadly I have no cards or paper tape now. The first thing I carried about regularly was cassette tape (CUTS format). BTW, DECtape is 3/4" not 1" as Jim suggested (slip of the pen?). I still have some, but alas no deck to read it on. -- Pete Peter Turnbull Dept. of Computer Science University of York

Another Atari Achievement...

by mor＠crl.com

This is one for the, "You can't do squat with those dumb old computers" file... I picked up a book at a thrift today, called, NEW HORIZONS IN AMATEUR ASTRONOMY by Grant Fjermedal (C) 1989. Before I got out of the first chapter I read this excellent little tidbit: "...David Gedalia, of California's San Fernando Valley, attracted a lot of attention by day and night with his 10-inch reflector on a servo-controlled Dobsonian mount. This was set up near the back of his pickup truck on the upper field, and on the tailgate of the truck was a simple 64K Atari 800 computer running a star finding program that Gedalia had written himself. He had all the objects from Messier (the classic catalog of 104 prominent galaxies, nebulae, and other objects identified in the late 1700s) and several hundred other objects from the more voluminous New General Catalog. It was so nice at night to see him enter a Messier number, hit "Return" and listen to the purr of the servos as they positioned the object right in the center of the eyepiece field..."

I too started with cassettes, but in my early years it was Apple II and Commodore VIC-20/C-64/C-16 tapes. A friend of mine (the owner of the C-16) didn't have a datasette. He's pretty artistic; he'd sit there for hours, plotting graphics through BASIC to the screen, only to lose it all when the power was offed. He did have a VCR though, and would record the images on VHS tape.

The system was wired into a 5 bay 19" rack > assemblage. It reads to me like what you got was the *processor*. And I have to wonder, why did you take it out? OK, I understand for transport but you also wrote that there was an expansion card frame (which might have more I/O cards) and other units in the rack. They may not be essential to operation of the processor but they probably do go together. Processors ain't everything ya know. > The item obtained is an "HP 2100S Microprogrammable Systems Computer". > It looks just like the 2100A shown at: www.trailingedge.com > > The card cage is fully populated but I haven't a clue at this > point with what, with the exception that I already know it does > have an async card (with associated moniter) and a GPIB > card (and cable). OK. If you take the top off, the cards in in the wider cage right behind the front panel are the CPU proper (in slots 1-7 I think, with options in 8 and 9 and maybe 10, though I may be off by one or two here -- it's been a while since I looked) and the I/O interfaces. The cards in the narrower cage about halfway back are memory (core) and drivers for same. The not-card-cage areas contain power supply and fans. There should be part numbers and legends on at least some of the card ears that give some clues what the cards are/do. Also the cards themselves will often have part numbers etched. Of course I don't have my books handy so can't post a handy decoder chart just now (and doubt it would be complete even if I did). Feel free to post a list, then sit back and watch us guess what you've got. Given that this one says "Microprogrammable" on the front panel I wonder if it has the WCS (Writable Control Store) option. All that said...the 2100 is a second-generation HP mini from 1972, the follow-on to the 2116/2115/2114 and predecessor to the 21MX that came later in the 1970s. These processors formed the basis of the HP2000 time-shared BASIC and HP1000 real-time computer lines, as well as many other special-purpose computer systems that HP developed and sold. Overall they are a 16-bit two-accumulator architecture; the 2100 is part hard-wired part microcoded with room for growth in the microcode, while the earlier 2116/2115/2114 were purely hard-wired processors. > Anyone interested in trading something for this beast? > > The biggest problem I see is that this thing weights > about 100 lbs. It would be expensive to ship. I'm interested but am thinking that you're in New Hampshire and I'm in California. Shipping is possible but you're right, you can't just toss this in a cardboard box with some peanuts or bubblewrap, so if someone closer by says the magic words ("I'll come pick it up") or you decide you want to keep it I'd say go for it. Besides, I'd want you to go back for the rest of it. Foo, I want you to go back for the rest of it *anyway*. -Frank McConnell

Been there four times since '93). You just searched a phon directory ? Didn't you ? Or who told you that I live near the Deutsches Museum ? True, my apartment is just 100m from the (back) entrance. Their _very_ early collection - up to the Zuse - ist quite good, but anything later is crap - or at least the display is crap - I left the museum society because of the computer displays. I'm especialy upset because they have _real_ unique things to show in a _unique_ way, but they just build some junk place. Ok, I have to be fair - the dispaly is quite amazing, but in my opinion they ignored a lot of one-of-a-kind chances just to finish it for the grand opening. Example: they recived a _complete_ SIEMENS 2002, the first fuly transistorized copmuter. Not only the main boxes - they got _everything_ needed to show the machine complete, including _all_ manuals, even spare parts. I think it would have been possible to rebuild this marvelous machine and power it up (ok, once) to show it. Maybe it is still possible, but it has to be done soon - right now several of the old tecnicans are still alive, but in ten years from now noone will be here to tell the story. Oh, next time when you visit the Deutsches Museum, take a look at the Operator desk of the 2002 - you'll find a burned spot, done by a cigarette. I know the guilty one - a friend of mine, now retired, did it while they tried to find a power up problem at the main drum - he acidently left his cigaret at te desk and got so involved that he forgot it - BIG trouble. > Wish I knew enough German to > actually speak it but Bayerische is even harder to understand ;) Amazing - I always had problems the other way. > Gruss!

I don't remember the exactr year, but I think it was in the first half of the 16th century. There are a lot of legendary stories around this device - inclundig the one that his whife had destroyed the first one, since she belived that this thing, going tick-tack must be devils work (remember 16th and 17th century was a or better _the_ high time of witch hunting and dark religous belives - Kepler for example had to defend is mother somewhen in the 1620s agains a triel of witchhood). So she destroyed his masterpice, and he let himself imprisson for the next few month in the city prison, to build a new one without beeing disturbed :) Building small time devices had an impact to trade like calculating machines in the early days of this century. Starting from coach clocks for merchants who lead their 'empire' from their coaches, until fob watches. in the 15th/16th century coach clock was an enormous expensive device - even compared th the expensiv travling coaces, a coach clock could cost up to 5 times the coach !

What if a special "hump" on a cam is so worn down > that one cannot reconstruct its shape? Some of the correct "shape" could > exist as aluminum powder. That's what I meant. Tony was saying - and rightly so - that while you can often see what a failed mechanical part was meant to be like by studying the failed component, and can then cut a new gear (the assumption was the gear isn't a standard part) / lever / cam or whatever, you can't possibly tell what a dead chip was meant to do just by looking at it. Likewise you can't tell what the value of that charred resistor used to be... I merely pointed out that with some tight tolerance cams and levers, you have a similar problem - you can't tell by looking. "Difficult" in my line above was a euphemism for "no hope" >> Bearing in mind Tony's, Sam's and others' comments on intermittent >> faults and the like, yes, up to a point.

For example (also a magnetic recording medium), > playing back a signal will never be the same as what was recorded, due to > noise and distortion. True, every word. But if you draw the distinction there - digital vs. analogue circuitry - the comment to which I was replying deserves your reply as well. The previous poster (wasn't you, William, was it?) drew the distinction at a higher level, and said something like "a digital _machine_ either works or it doesn't. Apart from video, the results are either right or wrong. With analogue/mechanical, things can be slightly out but the machine will go on working" Video is another analogue subsystem in a digital machine, just like a disk drive, and all that that implies... BTW, video may not make the change from digital to analogue until actually in the monitor, but the same applies - that which you see on the display is (at the digital level) either right or wrong. It is only when you get to the analogue bit that it is merely fuzzy. Philip.

FS: (cheep!) HP Controller 362

by higginbo＠netpath.net

I've got this Hewlett Packard Controller 362 and have no need for it. Anyone want it for the price of $5+shipping? It's about the size of a "pizza box" workstation, heck, I think it is a workstation. Boots up to something unix-like, has built-in VGA, 2mb memory, and a slot on the front for a 3.5" 1.44mb floppy drive, which I needed to scavenge for another machine. It weighs about 15 lbs. and I live in North Carolina, so shipping might be between $10-$15 depending on where you live. Features: HP-IB Keyboard connector, RJ-45? RS-232 Parallel HP-IB 98624A Card installed in the back, apart from the built-in HP-IB. Powe button on the front. I couldn't test it out too thoroughly, I did have a monitor to boot it up with, but no keyboard. Oh, and there's no HD inside the unit. I guess it takes an external HP-IB drive. If anyone wants it, first private response gets it. - - john higginbotham ____________________________ - webmaster www.pntprinting.com - - limbo limbo.netpath.net -

More stuff acquired

by jon＠techniche.com

Hi, Well this just goes to show how innate this collecting behavior is or maybe I could blame it on altruism? I went back to the surplus store today and picked up the old HP system that was there. This was not as simple as it sounds. The system was wired into a 5 bay 19" rack assemblage. The item obtained is an "HP 2100S Microprogrammable Systems Computer". It looks just like the 2100A shown at: www.trailingedge.com The card cage is fully populated but I haven't a clue at this point with what, with the exception that I already know it does have an async card (with associated moniter) and a GPIB card (and cable). I don't know what condition this is in other than the whole rack of equipment looks like it was decomissioned while still working. Most parts were still wired up. It hadn't been plundered (one or two rack slots were newly emptied). This unit appears to be in good shape. No dents or bent edges. One of the front switch covers is missing (these look like they pop off for lamp replacement). I even have the key for the power lock, an obvious indication that it has been taken care of! There was another expansion card frame in the same rack. Similar box but with no front panel switches. I didn't get this. It is probably still available. I also didn't get any of the i/o card edge connector cables that connect to the other equipment in the 5 bay unit. As it was it took me over an hour to extract this thing from its nest. I did take the GPIB and async i/o cables. Anyone interested in trading something for this beast? The biggest problem I see is that this thing weights about 100 lbs. It would be expensive to ship.

Actually the NS* contrller and the apple one are very close in that they are minimalist. The NS controller can read media without index/sector as years back I wrote a driver that did track read and writes for to see if I could use softsector media. I had to lay down a lot more marks thats all. The basic NS* read and write counts sectors, then waits for a sync byte and then reads. What the NS* controller cannot do is create the various marks that have missing clocks. Allison

In the early 1980s, I was one of the first in my school (I was 14 or so at the time) to own a floppy disk (yes, a disk, not a drive). I had heard of "flippy disks" with two index holes, which you could turn over, thus using both surfaces in a single sided drive. But I didn't realise you needed to give it a second index hole. So I just cut a second write-permit notch and turned it over. It worked! Commodore 4040 didn't use the index hole! Philip.

Maybe they even lend you the CD drive for a small fee. The other solution is just to keep the 40 MB drive and use it as boot drive or, third solution, just use it once paralell to copy the system folder.

Electronic, whether tubes or solid state, switching acts > directly on the electrons (or holes), hence the term] Different definition: In mechanical computers (and calculators) the information is proccessed and transported by mechanical actions/things - like wheels or pushin/pulling bars. In electronical computers information is processed and transported by flow of electricity. So the Z1 is pure mechanical (the only electrcal component was (is) the motor to drive all bars), while the Z3 is electronical. The Z2 was in fact a mixed up - The storage memory was mechanical (used from the Z1) but the CPU was electronic (Relais). You see ? There are mix ups already in the early evolution - Zuse even thought about using tubes instead of relais, but they have been way to expensive. Later on there have been again mixed ups. Relais + mechanical + tubes - or Tubes plus transistors + relais ... and so on. (Oh and even my APPPLE ][+ was a mixed up - he utilized a relay on the 80 colum card for switching :) > Was the Z3 like the Z4 in using old 35mm cine film for punched tape? > (don't try and read it with an optical reader!!!!)

The 8008 instructions (48) are simple enough that someone just learning how to write a computer program (Me back then) could understand all of them.

Need help with Mac Classic

by museum＠techniche.com

Hi Megan, If you're looking for a place to donate some computer (mac or otherwise), I'll take it. I'm trying to organize my personal collection in to a formal museum-like display. I'm always looking to expand that collection. At present it has 0 apple computer systems in it! I own my own software company and I am trying to do this in our warehouse area. I intend that it should remain a privately owned collection, but I'd like to open it up to public viewing, by appointment anyway. That way I could show it to groups like ham clubs, schools, software and hardware professional groups, etc. It's not a non-profit organization (in fact it's not legally any kind of formal organization, although my company informally subsidizes it), so there wouldn't be any tax write-off.

Old Mac OS.... Help PLS!

by yaksaken＠hkstar.com

Hi there.... Recently, I just got an old Mac IIci, which has 40M HDD & 8M RAM. After all, I added the RAM to 32M, and also want to change the stupid 40M SCSI HDD to a larger one.... But the problem is, I just can't find a diskette version of Mac OS 7.5.x for it... What can I do...?? If anyone has the old Mac OS, would you all pls make a copy for me?? I will pay the shipping and diskette cost..... (Coz, I don't think if I can get a new copy from APPLE.. :( ) Yours, Ken Yaksa

Curious George Goes to Micro Center

by maxeskin＠hotmail.com

An anecodote: Today, two teachers from my school went to Micro Center to get some stuff fixed, and took me with them. This was the first time I have ever been in a tech service room. There was one tech, a woman in her 40's, multitasking. She was only able to fix our printer, which wouldn't formfeed due to a gob of glue. She "solved" the other two problems with updates from Apple's site. Anyway, while she was busy with us, a guy walked in with a Mac Plus mouse. She told him that the only thing that could be done is to order a new one, if they're still in stock. One the bright side, she didn't sell him a DB-9 Intellimouse but I think the only reason a mouse should be replace is if the case is smashed or it just sucks (Zenix?). How do you expect classics to survive in active use if they're thrown away without an attemp at fixing them? By the way, what's the difference between DB and DE connectors? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Babbage died 1871 :) The Analytical Machine was never build and had never worked. Even the 1991 'replica' of the National Museum of Science and Technology in London was only build after his plans _and_ additions 'known' at this time.

And the first electronic computer is the Z3 since the Z1 was just mechanical. Also both are the first binary floating point computers (Babage used decimal wheels). Servus H.

Some cams and levers, though, have quite tight tolerance spikes and notches which it is quite difficult to get right from seeing the bent/broken ones. > Fixing one of these mechanical computers, however, is completely different > from the familiar digital ones.

Bearing in mind Tony's, Sam's and others' comments on intermittent faults and the like, yes, up to a point. Video is not the only exception, though - other things (e.g. disk drives) can suffer similarly. And finally, remember digital mechanical computers do exist - I have a Facit mechanical calculator with some quite sophisticated algorithms (optimised multiplication, non-restoring division) done digitally, entirely with mechanical parts. (The only electrical bits are a motor and a switch.) Philip.

My two favourites are both from BBC Micros: 1) a manufacturing fault: a particular machine would work from cold, but fail after about half a minute. It turned out that the IC used to select bank-switched ROMs had been inserted with one pin bent under the chip. It actually looked like it was properly soldered from the top side of the board, and impossible to tell from the underside, because the manufacturing process had skimmed all the protruding pins virtually flush with the board (onme particular subcontractor sometimes skimmed too close and damaged the tracks, but that's another story). Anyway, when it was cold, the bent pin touched the solder in the hole. When it warmed up even slightly, the other pins apparently expanded just enough to raise the IC and the bent pin lost contact. 2) a design fault: the original BBC used a ULA for video timing, and once it was in production, it was quickly found that many would start to give timing errors (manifested as twinkling characters) when they got warm. ULAs do run fairly warm, but they aren't supposed to need heatsinks, so this was a bit puzzling. It turned out that some gates in a chain had been set up as open-collector when they should have had pullups; when cold, the characteristics were such that the output got to a reasonable level quickly enough for the input it was driving, but when the IC was hot the level changed too slowly. As John Coll (who ran the original training courses) put it, if you could drill a hole in the top of the IC, and connect a pullup resistor to the correct gate with a microprobe, you wouldn't need the heatsink. Later versions of the custom chip were indeed provided as "heatsinkless". -- Pete Peter Turnbull Dept. of Computer Science University of York

Anyway, I digress, if you import your file into a newer version of word, then save as,with the file type HTML Alternately, there was a plug in released by MS called internet assistant.

HP 9825 configurrationss

by rigdonj＠intellistar.net

For anyone that cares, here is a list of the configurations of my HP 9825s. Notice there's some funny stuff here. Some are marked 9825A on the back but 9825B in the front next to the display. Several are marked 9825T under the paper cover. #4 says A on the back, B next to the display and T under the cover! You figure that one out! Many of them have a list, under the paper cover, of ROMs that are installed internally in the machine. The ROMs listed are not the same on every machine and they're listed in differnt orders. Also some machines have different amounts of memory. The box mentioned on some of them is a small box that extends out the back where the power cord plug in is located. It looks like a noise filter was added on to some of the machine. Some of these also have the operating system located in a plug ROM located in the side of the machine.

Using cards in such a manner would be like kinda using a ROM chip as a character generator for a CRT display.

The IDE is locally buffered just like SCSI so there is no need for speed save for the host can make requests very fast (Pentiums). IDE is also an async bus. Allison

old mac cards

by pcoad＠wco.com

As part of a deal I got a small pile of Mac nubus cards. My goal is to identify them and find them new homes before I need to get them shots, fixed, or they start reproducing in my closet like the 1200 bps modem cards seem to be doing. Farallon PhoneNET Card It has AUI and 10BaseT connectors. This one looks like an ethernet card. Is it? Apple Ethernet? card Has what looks like an AUI connector (female 15 pin) but without the locking slide device. Also has female BNC connector. On solder side it has "APPLE COMPUTER (C) 1987 820-0207-A and the word "hoke" near the upper back edge. Apple Macintosh IIci Cache Card (nubus) Duh. I can make a good guess at this one. Unknown nubus board Has markings DRO1 DEMO PC 10-184464- SER. NO. AA on component side. Has several unmarked chips and empty sockets. There is also a good deal of loose blue wire running hither and yon. On the end is a female 37 pin connector. Obviously this is a prototype. Is there any way to find out for what? Make me an offer. I have no way to test these cards. They are offered as is. As always I am looking for cool/old/strange/small Sun stuff. Cash is good too. Thanks, --pec -------------------------------------------------------------------------- The Antique Computer Collection: http://www.wco.com/~pcoad/machines.html

Well, they had an MCA bus- clearly superior! In fact, they were the closest anyone had ever come to PnP on a Wintel before USB and PCI. Except, it worked much more reliably.

How many different 9825B variations were there? There's at least three vesions, the A, the B and a T. The latter ones had most of the optional ROMs built in. BTW I just bought another one, it has a big warning label on it not to use any plug in ROMs other than the Matrix and String (I think). It says that the others are already built in and if you add a plug-in one that you may damage the calculator. I have lots of docs for these and 6 other 9825s but this is the first time that I've seen that warning. There are also two very different keybaords used on them. The 9825 at the bottom of your picture has the full travel keyboard. They're more desireable.

Did anybody >ever make a similar model, but with, say, an 80x24 character LED display? Yes, HP did except they used a CRT. The HP 9826 replaced the 9825. The 9826 was shaped like an oversized Apple computer and had an integrated keyboard, 5" monitor and 5 1/4" disk drive. You can see one on my webpage at "http://www.intellistar.net/~rigdonj/hp9000.htm". The 9826 used a 68000 CPU and could run HPL, BASIC or Pascal. All of the languages were USUALLY stored on disks and loaded from there but you could get the languages on plug-in ROM cards. You could have any or all languages on the same drive and/or in ROM on the same computer and you could select the one that you wanted the computer to load. I have a drive with all three languages on it and BASIC in ROM on one computer. The 9826 was also called a 9000 226 model and was part of the HP 9000 series 200 computer family that included the 9836 (aka 9000/236), 9836C, 9816 (aka 9000/216), 9000/220 and 9000/217. Even though the 9826 was designated as the replacement for the 9825 all the computers in that family are generaly compatible. The primary differences were the number of expansion slots, integrated vs. modular construction, overall size, number of built in drives and wheather they had monochrome or color displays. I have pictures on several of them on my website. Joe > >-- Doug > >

Uhh, lets not confuse .308in bullet size with bullet caliber. The .308 Winchester cartridge was introduced in 1952 and adpoted in 1954 by the U.S. military. It was designed with a reduced overall weight(a little shorter). The idea was that a G.I. could carry more ammo into combat! The correct military designation for this cartridge was 7.62x51mm NATO. BTW, I believe it's "aught" with an A! Sorry, computers are not my only hobby. Cliff Boyer

HP 9825B

I spent a couple of evenings trying to figure these things out (have two, an A and a B) with mixed results. HPL is definitely case sensitive. The little dinky manual that fits under the printer cover is not enough documentation to learn how to program it.

Oh, did these things come with monitors at all? Most of the ones we had at university had 12" mono screens hooked up to them, but I don't know if they were original or not (I have a couple of these - similar shape to DEC VT320 terminals). The manuals I have (IIRC) both mention that the systems can be expanded to run CP/M, but no mention of how or what was needed; there's no pin-outs of the expansion port, cartridge slots or anything. > >> Owning a Alphatronic PC and 2 Alphatronics hmm, so what's the difference between the two? Mine are all badged "Alphatronic PC", but I checked with the university staff before I left and they never had any floppy / hard drive systems with them... (This is where I really hate not having my collection around at home, it's been so long since I've powered one of these things up I can't even remember what CPU they had. I vaguely recall that they had a lot of fairly non-standard chips inside though; the CPU may have been a rebadged part of some description) cheers Jules >

For all intents it was not unlike the usually vendor unique hard sector formats. Also DBASEII ran well on apples with floppies. The only penelty of reading an entire track was memory space. The payback was speed as there was an implied track level caching. Allison

CP/M

by allisonp＠world.std.com

16 blank lines deleted. <Did MP/M run on Z-80s? BTW, is there a reasonable chance the CP/M on Yes and 8080s as well. The later version for 8088 were called CCPM (concurrent cpm). IN both cases they were multiuser/multiprocess OS that were really better than most. The z80 version was pretty decent on a 6 or 8mhz banked machine that had DMA for disk IO. The DMA was important as some hardware sued the cpu spinning in tight loops to do PIO to floppies and HDs, very inefficient used of cpu cycles. A common use for MPM was to use it for disk services to multiple slaves running cpm2(or 3) or CPnet. A crate constructed that way could easily have a z80 per user plus the MPM server and provide excellent response in a compact box. TELTEK, KONAN, macrotech and others offered cpus boards for both services. The difference in the boards were generaly amount of ram and presence of disk interfaces. <one micro w/5.25" disks be compatible with another with 5.25" disks, <i.e. my apple with a C-128? Also, if a computer can run CP/M 3+ can it Apple is weird with their formats, nearly hardsector. C-128 has a few compatable and incompatable formats. The rest were all over the map. Allison

uV SCSI/ DMA-Incomplete messages

by allisonp＠world.std.com

<Anyway, concerning the uVAX SCSI/DMA code, seeing as <1, the SCSI code works most of the time, and <2, retrying when it fails clears the problem (most of the time), <why not patch the DMA code to retry an operation instead of failing <and returning SIGSEGV? Of course, this will get you when something actua <fails, but could it be tried? Err, how about fixing the scsi code so it works correctly and only flagging fatal errors or warnings where warrented.

Inventory compaction

by maxeskin＠hotmail.com

My mom got fed up by the amount of junk I have in my room, so I will start to get rid of it (something I'd been planning to do). I have an external keyboard that plugs into the keyboard socket on the Apple ][ motherboard. It works fine, weighs three pounds. It has macro modules for basic, CP/M, wordstar, visicalc that plug into a little socket and modify a row of keys at the top (templates included) A little yellow, though. Anyone want? The other item is the 10-pound DG-One laptop with a smashed screen, no AC adaptor, dead battery pack, and BUTTONS on the floppy drives! I am zip code 02135. If anyone wants either just tell me. I also have a TI 99/4a w/o cartridges, seems to work fine. I think I'll just trash that... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

yes, i did the same with apple ][ floppies. i never used the special tool to punch the index hole as a sharp x-acto knife worked well. i do have one box of flippies at home and i never had a problem with using the "wrong" side. In a message dated 98-06-17 12:33:56 EDT, philip belben put forth: << Likewise the Commodore 8-bitters. In the early 1980s, I was one of the first in my school (I was 14 or so at the time) to own a floppy disk (yes, a disk, not a drive). I had heard of "flippy disks" with two index holes, which you could turn over, thus using both surfaces in a single sided drive. But I didn't realise you needed to give it a second index hole. So I just cut a second write-permit notch and turned it over. It worked! Commodore 4040 didn't use the index hole! Philip. >>

I vaguely recall that they had a lot of > fairly non-standard chips inside though; the CPU may have been a > rebadged part of some description) The Alphatronic PC was the last version of a somewhat successfull line of Alphatronics - The PC is a keyboard computer like the ATARI XL (but with a real keyboard) and based on the Z80. The 'old' Alphatronics where clumpsy cases with fixed keyboard like the CBM, but without a build in CRT - but they had TWO 5,25" 2/3rd high FD drives - both on the right side, one above the other - the case was quite big. As a CPU the 8085 was used. The whole system is build on several EuroCard size boards (all in a rack on the left side - thats why the FDs had to be on the other side. They has several variations (I don't want to call it modells) over the time, but basicly all the same. In Europe, especialy in Germany (their orgin) they sold like Commodores and Apples in average quanities. The PC has been directed to open the home market and to compete against all the home computers of the early '80s. I have some of the early documentation for the old ones, and maybe some newer stuff (manuals for disk etc.) Servus Hans -- Ich denke, also bin ich, also gut HRK

<OK, I know what a track and a sector is, but what is the difference <between hardsector and softsector Hardsectored uses physical landmarks like index and sector holes on the media to locate sectors. Softsector uses various data marks on the media to locate the data. It's possible to do a hard sector scheme that looks like softsector but, the difference between them in older machines is the basic format is such that most controller chips like the 372, 1771, 1791, 8271 and 765 cannot read them. Apple combined and simplified the disk controller to software and some trivial logic. Allison

CP/M

by photze＠batelco.com.bh

C'mon. Even I basically know this one. A hard sectored diskette has tiny little holes (IIRC, near the inside), so that the computer would move from one to the next in a mechanical manner (hardware), while MOST soft sectored diskettes had a single hole used for refference. From there, it would just spin around, and control the rest by software. The Apple II, however, COMPLETELY ignored this. It could use hard sectored or soft sectored diskettes, or even diskettes with no little hole at all. It was completely software driven. Ciao, Tim D.

Prodcutivity (was Re: PDP model line / rarity?)

by maxeskin＠hotmail.com

Win without Intel make either a small frisbee or a coaster for tea. You can also make art out of them. However, I read in "Insanely Great" that a study had been run in the early 80's that didn't find computers to have improved productivity.

Big Iron Was:RE: Backwater areas Was: Re: Cross listing Ebay items

by jfedorko＠virtualadmin.com

I'd almost be interested in a gutted 360 if the front panel was intact! Speaking of big iron, what's the best place to look for DEC10s or 20s? Maybe even a 360/20? I think a 360/90 would be neat but the CPU and cooling would fill my garage. -----Original Message----- From: William Donzelli [SMTP:william@ans.net] Sent: Tuesday, June 16, 1998 11:33 PM To: Discussion re-collecting of classic computers Subject: Re: Backwater areas Was: Re: Cross listing Ebay items > My problem is not so much distance as it is time.

That is why I put in all of those "assumes". I know planning such a trip is almost impossible for those of us that have lives/families/jobs. I just wanted to see just how far some of us would take the hells of the Interstates. Incidently, I do not drive the Interstates much, as there are not many junkyards along them. US routes, on the other hand, have them. If anyone wants a pair of gutted S/360s, I will show them just where along Illinois 1 to find them! William Donzelli william(a)ans.net

<Ultrix was a layer over VMS. Nowadays there is an official DEC Unix Sorry no, I have Ultrix4.2/VAX and it's unix alright. <for the Alpha, though not as good as Linux for that platform. IMAO. I'd be surprized it that were true. DIGITAL Unix has a more mature development path. I also have VENIX on a PRO350, can't tell it from V7 in the 11/73. Allison

Time for the FAQ

by dastar＠wco.com

I'm not making a statement or anything by posting the FAQ. It's just been a while so its time for the recent newbies to the list to get a dose of it. ============================================================================= DO NOT DISPOSE OF THIS PART OF THE FAQ. THIS IS THE PART THAT EXPLAINS HOW YOU CAN SUBSCRIBE AND UNSUBSCRIBE. IT WILL TAKE ME MORE TIME TO DO THESE THINGS FOR YOU THAN IT WILL TAKE FOR YOU TO DO THEM YOURSELF ============================================================================= ClassicCmp - The Classic Computers Discussion List Part 1 in the ClassicCmp FAQ Trilogy Mail/Internet Basics FAQ (Frequently Asked Questions) v1.3 Last Update: 12/10/97 ----------------------------------------------------------------------------- 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 1 of the ClassicCmp FAQ Trilogy. The information presented deals with the use of mailing lists and internet-specific tools. 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://haliotis.bothell washington.edu/classiccmp or via anonymous FTP at 140.142.225.188 in the directory /pub/classiccmp/faqs as cclpart1.faq. ----------------------------------------------------------------------------- Updates: Nothing new, cosmetic changes. ----------------------------------------------------------------------------- 1. Mailing Lists ---------------- 1.1 Mailing List Basics 1.2 How to Talk to the Robot How to set to Digest How to Subscribe How to Unsubscribe 2. FTP ------ 2.1 FTP Basics 3. World Wide Web ----------------- 3.1 WWW Basics ============================================================================= 1.1 Mailing List Basics A mailing list is a simple device which takes an e-mail and redistributes it to a group of people. People can add and remove themselves from the distribution list by Subscribing and Unsubscribing. When you send a message to the list, it is first examined by the robot for key words that tell it to process an automatic funtion (like help, subscribe, unsubscribe, etc). If the message does not contain a keyword it is sent to the distribution list. 1.2 How to Talk to the Robot There are a few List Processor commands that you might want to use. To send a command to the list processor, write a message to listproc(a)u.washington.edu (Do NOT send the message to classiccmp(a)u.washington.edu). In the body of the message (not the subject line, that is) write one of the following commands, then send the message. SET CLASSICCMP MAIL ACK Tells the robot to send you a copy of messages you write to the list. This is the default. SET CLASSICCMP MAIL NOACK Tells the robot NOT to send you a copy of messages you write to the list. I don't recommend this. SET CLASSICCMP MAIL DIGEST Tells the robot to send you a digest of messages rather than each as it is posted. With this option you will get a weekly bundle of messages and keep a nice, tidy in-box. SUBSCRIBE CLASSICCMP Your.Address Subscribes you to the list. UNSUBSCRIBE CLASSICCMP Your.Address Removes you from the list. [][][][][][][][][][] 2.1 FTP Basics FTP is a protocol by which files can be transferred over the internet. You can use FTP to connect to a remote site and retrieve files. The commands you use with FTP depend on the software you use. In general you must make sure that you are in BINARY mode before transferring a program file or compressed files. The process of downloading a file is usually termed GET and the process of uploading a file is usually termed PUT. Your FTP program will require an address to connect to. For the ClassicCmp site that address is 140.142.225.188. You then may be asked to log in (unless your program assumes an anonymous login). When asked for a name, use anonymous. When asked for a password enter your internet e-mail address. [][][][][][][][][][] 3.1 WWW Basics The only complicated thing with the WWW is knowing what bells and whistles your web browser supports. You don't really need to know much other than the address for ClassicCmp. The web site is all text which means just about any web browser from the oldest Lynx to the newest Netscape or Microsoft browser should support it. The ClassicCmp site is http://haliotis.bothell.washington.edu/classiccmp. ============================================================================= ============================================================================= ClassicCmp - The Classic Computers Discussion List Part 2 in the ClassicCmp FAQ Trilogy List Specific FAQ (Frequently Asked Questions) v1.6.3 Last Update: 12/10/97 ----------------------------------------------------------------------------- This FAQ is written with the primary purpose of making readily available answers to the more common questions appearing on ClassicCmp.

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. This definition has come under fire recently but remains the guideline. Remember that it is certainly flexible. The idea is to keep conversation on track, not to restrict what you can talk about. 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. As an update, I've been _really_ hard to reach for the last couple months. Hopefully, this has now changed. Please keep in mind that this list is recreation for me, and I sometimes cannot devote any time to it. This does not indicate a lack of interest in the people or activities involved. 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 20 messages to over 100. Average seems to be about (I haven't checked lately, will update) messages a day. There are times where the message load peaks for as much as a week. 1.8 How long has this list been around? The first message went out March 13, 1997. [][][][][][][][][] 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. If your post is commercial, please be sure to indicate that in some way in the subject line. 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? Some people like to read other peoples' trophy lists, some do not. There have been times when most people have been interested in these and times when many wanted to see them banned. So, they remain - appreciated or tolerated and somewhat controversial. Can't make everyone happy all the time ;) 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 210 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://haliotis.bothell.washington.edu/classiccmp 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 140.142.225.188. 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. ============================================================================= ============================================================================= ClassicCmp - The Classic Computers Discussion List Part 3 in the ClassicCmp FAQ Trilogy Technical FAQ (Frequently Asked Questions) v1.6.2 Last Update: 12/10/97 ----------------------------------------------------------------------------- This FAQ is written with the primary purpose of making readily available answers to the more common questions appearing on ClassicCmp.

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).

It was developed at SRI, I think by David Kashtan who was later one of the founders of TGV. Wollongong sold it, and supported it, but I wasn't involved in it except as an occasional user so don't have much to say. -Frank McConnell

PDP model line / rarity?

by JRichardson＠softwright.co.uk

>> The 8's are also pretty common. I believe they're one of the most >> common mini's ever built along with the 11. hmm. My university had a 7 which as far as I know was never used - it just sat there as a conversational point in one of the physics labs. I probably could have taken it, but just don't have the room for it (nor the knowledge to keep it running, and I don't have the time these days to learn about any new machines sadly!) Don't think I've ever seen any other PDP's aside from that 7 - either running or non-running. >>> Sorry for the dumb question - I grew up with classic 8-bit micros and >>> 32-bit Unix machines - shame I missed out on some of the big old boxes, >>> they sound like fun (if a bit impractical from a storage point of view!! >>> :) >> >> They were a LOT more fun than your average WINTEL box. hey, wintel machines are great fun - at least in the sense that they're amusing due to the terrible hardware and software that's a complete joke :) Jules
