You can get silica gel in bulk from any laboratory or craft supply house that caters for chemists, biologists, microscopists, mycologists (mushroom collectors) or people who do flower arranging (and drying). It's not always as cheap as you might think, though. I get mine by asking our techs to throw each little bag that comes with a PC/monitor/harddrive into a box at the end of their bench. Ask your local PC shop to do the same? Bear in mind that it works by absorbing (pedantically, adsorbing) moisture from the atmosphere in the region you're trying to protect, and there's a limit to what it will soak up. Some of it comes with an indicator: usually cobalt chloride; pink when moist, blueish-purple when dry. You can drive off the moisture by warming it in an oven at 130C for an hour or so (the time tends to depend somewhat on the quantity and packaging). -- Pete Peter Turnbull Network Manager University of York

Semi-OT: Virtual PC 7 on Mac OS X

by healyzh＠aracnet.com

Does anyone have any experience running MS-DOS 6.22 on VPC? I've managed to get Win3.1 running in SVGA mode at 600x800, and I've got some of my old DOS software copied over. What I really want to know how to do is access the CD-ROM, Ethernet Card, and if possible get video drivers for the S3 card that VPC emulates. Oh, and I need a mouse driver for the PS/2 Mouse so I can run a couple games :^) In case anyone cares, so far I've gotten the following working: AROS BeOS 4.5 BeOS Max MS-DOS 6.22/Win 3.1 Windows 98SE Windows XP Pro SP2 (it came with this, so it had better work) Obviously only Win98 and WinXP support the cooler features such as mapping folders on the Mac as network drives, and printing to the Mac printer.

>Obviously only Win98 and WinXP support the cooler features such as >mapping folders on the Mac as network drives, and printing to the Mac >printer. I'm sure I've mapped DOS in VPC to both shared folders and printers. Although this would have been with much older versions of VPC (v1, 2 or 3). I do know for sure that I have run WIn95 with both. But who knows, this is now MS VPC, so I'm sure they made any features that might be useful work exclusively with whatever version of Windows they want to make you use. -chris <http://www.mythtech.net>

Stephen Dorsey and Micom

by geoffham＠gmail.com

Hi Lawrence, I was just perusing the ClassicCMP archives and noticed a post you made on Fri Nov 15 20:18:14 2002 about the Micom - a computer that was very much ahead of its time - and wondering if its founder Stephen Dorsey was still alive. He is very much alive and kicking: he's in Montreal and now the president of BabyTEL, a major Voice-over-IP company in Canada and subsidary of Voice & Data Systems. I met him through a business connection - truly a fascinating man, and still working in fields that are ahead of their time (he's been working at VoIP since the early 90s!). Let's hope he get rich this time. Geoff

Although I seem to recall when I looked into them they weren't super cheap.

drum stores

by julesrichardsonuk＠yahoo.co.uk

<happy dance> we're getting a drum store! </happy dance> Just been offered a late 1960's BCL Susie accounting machine - delay line accumulator and all the usual suspects (card reader, tape reader / writer etc.). Best thing being that it has a 64 track drum - as you know I've been after a machine with a drum for the museum for some time now. Sounds like it's been in a shed for the last ten years though so the owner's checking what kind of state it's in. Experience is that machines of that era survive moisture remarkably well though, so fingers crossed. Moving it's going to be interesting. :-) cheers Jules -- "We've had a lot of loonies around this place, but you're the first one who thought the sunrise was made out of stale beer.

access to BIOS of DECpc

by bobcaar＠softhome.net

I've used a copy of Ontrack Disk Manager (~version 4?) from Seagate and it works with any brand drive. If you still need it, I can dig it out when I'm home in a couple of weeks and image it. I believe it will work with any settings in the BIOS, although it does recommend certain ones. T.H.x. Devon --------Original Message--------- Date: Thu, 21 Oct 2004 09:52:29 +0200 From: Gooijen H <GOOI(a)oce.nl> Subject: RE: access to BIOS of DECpc I found the SET320P.EXE program on the COMPAQ site, and it allows several items 'normally' found in a BIOS to be manipulated. Alas, there is no field to change the hard drive parameters nor the type! The disk manager was a good idea, I have one old 486 PC with a big Western Digital drive, too big to be supported by the BIOS, and the EZ-DRIVE disk manager works perfectly here. However, EZ-DRIVE only accepts to work with Western Digital drives, and the 2.5" hard disk that I have is from HP. The disk manager also wants certain settings for the hard disk in the BIOS ... Still not giving up / one more try: could somebody point me to a site that has a non-commercial disk manager (for HP or not restricted to specific HDDs) or even better e-mail a ZIP with such disk manager?

(Fwd) FW: UCSD Pascal Reunion Symposium 10/22

by ss＠allegro.com

Of possible interest to UCSD Pascal fans... -------------------------------------------------------------------------- >From Kelly Briggs (kbriggs(a)soe.ucsd.edu) Subject: UCSD Pascal Reunion Symposium 10/22 Dozens of alumni will gather at UCSD on Friday, Oct. 22, to mark the 30th anniversary of the computer language UCSD Pascal, one of the first languages of the personal-computer era. The UCSD Pascal Reunion Symposium will take place from 1 p.m. to 4:30 p.m. in the Price Center Ballroom, and will be open to the public, free of charge. (To register, go to http://www.jacobsschool.ucsd.edu/Pascal/registration.sfe.) The UCSD Pascal symposium is organized by UCSD?s Jacobs School of Engineering and its Computer Science and Engineering (CSE) department, and is co-sponsored by the California Institute for Telecommunications and Information Technology. The event will feature talks by several former researchers on the project, including UCSD Pascal?s founding father, professor emeritus Kenneth Bowles, who will speculate on "Pascal: What If?". Other speakers include Richard Kaufmann, class of ?78, now a distinguished technologist at Hewlett-Packard, who will reminisce on "What the Heck Was UCSD Pascal?;" Roger Sumner, ?77, president of Beach Software Designs, who will discuss Pascal?s far-reaching impact; and CSE professor Henrik Wann Jensen, on ?Digital Illumination.? Following those presentations, CSE professor Stefan Savage will moderate a roundtable discussion among Kaufmann, Sumner and four other members of Bowles? early research team: Mark Overgaard, '78, President, Pigeon Point Systems; John Van Zandt, '76 '79 '86, President, CEO Consultancy, Inc.; Keith Shillington, '78, Co-Owner, E Street Caf?, Encinitas, California; and Lucia Yandell, '78 '80, JSF SW Process Lead, Northrop Grumman, ST Radio Systems. UCSD Pascal became both a programming language and an operating system for some of the earliest personal computers. Its development not only put computer science at UCSD on the map in a big way, but its innovations also had a major impact on developers of other languages and operating systems at Apple, Microsoft, and elsewhere. Pascal was originally created by Swiss scientist Niklaus Wirth in 1969 for use on mainframe computers. But starting in 1974, Bowles ? who at the time directed UCSD?s computing center ? began to adapt Pascal for use on so-called "microcomputers," precursors of today?s PCs. At one point or another, more than 70 students were involved in the UCSD Pascal project, and by 1983, UCSD Pascal had become an ISO standard language. The University of California then sold the technology to SofTech Systems, which tried but failed to convince IBM to adopt UCSD Pascal as the core operating system of its first personal computers. (Microsoft's MS-DOS won the IBM contract.) For a history of the UCSD Pascal program, including recollections from many of the speakers who will attend the symposium, read ?UCSD Pascal and the PC Revolution,? by Christine Foster, in the September 2004 issue of @UCSD. It is available online at http://www.alumni.ucsd.edu/magazine/vol1no3/features/pascal.htm . For the complete program, go to http://www.jacobsschool.ucsd.edu/Pascal/ . We hope to see you there! ------- End of forwarded message -------

Agreed that it's possible, and when I get the time I will go through it, I was just explaining why it would be nice to have someone measure the power supply pins so that I would have a starting place. I can basically identify all of the pins on the power socket - but I heasitate to assume +/-12 for the analog - It would be nice to at least have a no-load measurement... If I can't find any information, it may come down to doing what you suggest.

Excercising vintage items - was: Commodore 8010 IEEE-488 Acoustic Modem ?

by dave04a＠dunfield.com

>That's unfortunate but not surprising... it's not a common thing. If >I had one, I'm not even sure I could find a use for it. I have to admit - I do not have a burning desire to connect to anything at 300 bps --- But I do have a burning desire to see it work. These are a questions that seems to have different answers from different collectors: - To use or not to use - To fix or not to fix - To power-up or not to power-up I spend plenty of hours fixing things that I know I'll never really use --- I like to know that the items in my collection actually work, and will continue to work as long as I can maintain them. I guess my idea of preserving this material means preserving it in working condition. I also LIKE fixing this stuff... I like the challenge of tracing a problem, and the insight that comes from figuring out how a particular design works. I know collectors who rake all the stuff up into a big pile and never even try it - just "having" is enough. I know collectors who check that it works, and then never turn it on again, because "it might stop working". I know collectors who focus on a very small area, and actually use the equipment on a daily basis. Personally, I cycle through the things in my collection frequently - I try and run everything at least once or twice a year (usually several times a year). I enjoy fooling with the different machines. I also demonstrate them working at every opportunity - I've taken vintage machines to local schools to let kids experience some of "how we got here", I take them out to local clubs and meets, and I show them to anyone who wants to drop by and see them. I often loan them out, although I do want to satisfy myself that they will be reasonably well taken care of first. Whats the point of storing all this stuff unless people can actually experience it - otherwise, why not just keep a pile of pictures. If a machine breaks - I fix it. IMHO, a machine that you can't use because "it might break" is no more useful than a machine that doesn't work in the first place. So - most anything that comes in here I try and get working. In this case, I think it would be "cool" to be able to demonstrate a PET connected through the 8010 IEEE modem to my Hayes S-100 modem (also a 103 type) in an Altair running a BBS system - This would show how it really worked! - but I don't expect anyone to actually want to use such a setup for any other purpose. Curious to know what others do with the vintage equipment you have stashed away in basement/garage etc. Regards, Dave-- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector. http://www.parse.com/~ddunfield/museum/index.html

Typewriters?

by mouse＠Rodents.Montreal.QC.CA

I seem to recall people mentioning, here, typewriters - good old non-computerized typing machines. I know someone who is looking for one. Doesn't need to be fancy; indeed, fancy is a disadvantage here, or I would have already set said person up with a computer+printer solution. "Electric, but not electronic." It does need to be functional, though; the idea is to use it, not put it on display or suchlike. Anyone got one and willing to let go of it for some reasonable amount? I can write a cheque for the machine plus shipping and scare up a shipping address, if there's reason to. (I phrase it that way because the place it'd be going is in a very rural area of western Canada, and I'm not sure what shipping methods would be workable - but I can find out from the putative recipient.) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Other apparent power sources from the connector head off into a maze of op-amps and other analog circuitry, even with schematics it would take a bit of work to figure out what supplies it was designed for... I'm hopeing that I can find someone with this modem that can measure the pins on the "wall wart" - at least then I have a starting point, knowing the approximage no-load supply voltages.

I got it quite by accident - I talked my wife into a 2-hour detour on our Thanksgiving getaway (would have been a 10-hour drive later) to pick up a "small load" of equipment that had been promised to me - I also warned her to "pack light" -- ha..ha.. I completely filled the back of my Jeep from floor to ceiling (which we ended up hauling around all weekend). After I had everything packed, the guy started digging out little bits of stuff from his garage, which I kept stuffing into nooks and crannies, near the end he offered me this acoustic coupler, and it was only because it said "Commodore" on it that I decided to find room for it (by then it was getting pretty hard to find ANY space) - it wasn't until several days after unpacking and going through the stuff that I looked at it closely, and realized that it had the PET-IEEE interface.

Appearance on G4TechTV's The Screen Savers

by vcf＠siconic.com

So I'll be appearing tomorrow on The Screen Savers on G4TechTV (just about everyone in the US should be able to catch it since the merger opened up both collective channels to most major cable/satellite systems). The live show airs at 4pm PST (California) and usually repeats a couple times after that every 3 hours or so. Check your local listings for exact air times. I'll be demoing a PDP-1 front panel replica hooked to a laptop running the PDP-1 emulator on SIMH, further running Spacewar! with Phil Budne's XY simulator code. I've also constructed some Spacewar! controllers modeled after the original MIT controllers that will be used to play the game. The front panel will be blinking and all that. It should be interesting (somewhat) to watch. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

I would like to know what the difference is between a 23512 eprom and a 27512 and if there are any differences if its possible to make some sort of adapter. Had a look at some schematics and they looked the same to me, data lines on the same pins etc. Any help is welcome. Ow the reason I want to know this is that I want to read some old roms in my EPROM reader. Cheers, Stefan.

Apple Mac XL/Lisa 2

by witchy＠binarydinosaurs.co.uk

Folks, Just collected a Mac XL (Lisa 2/10) that annoyingly was upgraded from a Lisa 1 then the back and top panels were stolen at a trade fair! This means I've got Lisa 1 internals (R41 and R47 cut from the IO board, new ROMs etc), keyboard, mouse but no twiggys or front panel, AND it has the screen kit fitted. Oh, no widget either....the hard drive is a Seagate ST225 connected to a parallel card in one of the 3 slots. Anyone know if this kit is reversible? Anyone have any spare twiggys? :o) This is as close as I'm going to get to a real Lisa 1 for the forseeable future! I also got Lisa 7/7 V3 docs and floppies, Macworks Plus box and floppies, Lisa screws/fixings kit and a Stylewriter II with a Localtalk card fitted. I haven't dared power it up yet! The Lisa is one of those beasts that's all or nothing 'cos the PSU does more than convert 240V to 5 and 12 volts. So, to recap, I'd like to get my paws on the following: 2 twiggys (possibly with the LisaLite board) Lisa 1 front panel, top panel and back cover Lisa 7/7 on twiggys (at least I know THAT's available) the moon on a stick a winning lottery ticket :oD -- Adrian/Witchy Owner/Curator of Binary Dinosaurs, quite probably the UK's biggest private home computer collection www.binarydinosaurs.co.uk - the online museum www.aaghverts.co.uk - *the* site for advert whinges! www.snakebiteandblack.co.uk - former gothic shenanigans :(

Commodore 8010 IEEE-488 Acoustic Modem ?

by dave04a＠dunfield.com

Hi Guys, I was recently given a Commmodore MODEM Model 8010 - this is a Bell 103 (300 bps) acoustic coupler, which has an IEEE-488 connection for use with Commodore PET computers. I am looking for: - Information on the power supply - I did not get a power supply with the modem - it has a 5-pin DIN type connector. Can anyone give me the pinout and power requirements? - Documentation? Anyone have a scan of the manual? - Information on how it is used ... What sort of IEEE device does it show up as? Is there "special software" that is used with it? etc.? Regards, Dave -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Vintage computing equipment collector. http://www.parse.com/~ddunfield/museum/index.html

Fwd: Re: museum phone number?

I apologize again for cutting you off during our phone conversation... I was expecting someone and they'd arrived.

Blowing Up Old Computers

by celt＠chisp.net

I wonder how long it will be before some fool donates a PDP or some other piece of kit we hold near and dear to our hearts, to these miscreants. Sure, it's amusing when it's a 286 being pipe-bombed, but probably not so much fun (for me, anyway) when they get their hands on an Amiga or a Sol. It's all fun and games until someone loses an eye... http://www.letsblowitup.com/default.shtml

access to BIOS of DECpc

by GOOI＠oce.nl

Thanks Dan, I feel a bit silly, but it was late last night is my excuse. "DECpc 320P" in Google gave a link to floppy images on a COMPAQ site. I will try them this evening, but it is good to know that the DECpc "knows" a limited number of hard disks. If I can 'upgrade' to some 300 Mb of the 420 Mb capacity it is still better than the 40 Mb that I have available at this point. - Henk, PA8PDP. > I know these machines only have 46 or so built in geometries of disk > type.

access to BIOS of DECpc

by GOOI＠oce.nl

Hi all, I have this DECpc 320P which has a 40 Mb hard disk in it. I installed a 420 Mb hard disk, but it keeps being recognized as 40 Mb. I can not find a way to get into the BIOS, and those old PC's normally had a "utility floppy" to get access to the BIOS ... fdisk says 40 Mb. I guess it is OT as it is a PCP11-CA notebook computer from DIGITAL with a 386 CPU and a sticker on it from DECcare (valid to Jun 1994), so it must be at least 10 years old :-) This beastie has a black&white screen (no colors), but the name is just perfect (PCP*11*) and I would like to run E11/SIMH on it, but 40 Mb is a little small and I have this 420 Mb disk ... Who can tell me how to get into the BIOS (assuming that I can from there change the hard disk drive parameters) ; a ZIP-file with the utility disk would also be very welcome! TIA, - Henk, PA8PDP.

Altos 586

by sastevens＠earthlink.net

Hello, I am the happy recipient of an Altos 586 system that was listed available here a few weeks ago. I have the machine safe and up and running now. I apparently was the only person who replied to the offer of the machine, but am hoping there may be others here who have this system. Mine arrived with Xenix 3.0 installed on the drive, but I have no installation media. I had one of these systems years ago with the installation media but passed the machine and diskettes on with the machine. The Altos 586 is actually a rather interesting machine. It runs Microsoft ('pre SCO') Xenix, based on System 3 UNIX. This particular machine supports five users on it's row of serial ports, all connected on dumb terminals or terminal emulators. It's not a very robust UNIX but it is interesting to note that Microsoft sold a UNIX capable of supporting 5 users on an 8086 processor in 512K of RAM (classic UNIX, of course, could support many more on less RAM, but this is still a pretty cool machine). Any help or leads people can offer for this machine would be greatly appreciated.

KSR33

by res20nop＠verizon.net

Hi All I didn't realize this was a group listing but that's OK. I would like to let you all know that the PDP11 is gone. It went the following day. I would like to clarify some things that seems to be the real issues with the KSR33. I am located on the West Coast in Portland Oregon. My mistake for not putting that in the original note. There has been concern about the shipping costs and the actual packing of the TTY for shipment. I have never had to pack up something like this or know what the costs would be for shipping it to the East Coast. It seems like most of the responses that I got were somewhere near the east coast. I am really interested in getting rid of this TTY but I need some more explicit help on how to prepare this for shipping. Ken

Classic OS's - TSS/8

by aek＠spies.com

> What is that, a TU-11? -- UWM had a TU-56 drive and a TC08 controller, an RF08, and two RK05s with mods that Bart and Sam did to the monitor to support it before DEC supported them. It also had a high speed paper tape reader/punch. > Did you ever work with Dick Bartlein, or SaMilosovich? -- Yes. Bart and Sam were still around when I started. I was one of the people who dismantled the system when the 750 moved in. I still regret giving the DECtapes away to Gary Coleman in Cleveland. There is a small chance that Jeff Russ may have ended up with them when I bought Gary's collection, but I've never been able to get a DECtape inventory from him.

Classic OS's - TSS/8

by aek＠spies.com

Any information on TSS-8 is always greatly appreciated [I have a decent collection started] as well as hardware or actual software. -- The version that John Wilson used and the one that I used at UW-M are up at www.bitsavers.org/bits/dec/ascii (basic, johw, uwmMonitor) Binary paper tape images from John are at bits/dec/pdp8/papertapeImages/set1 The LINCtapes from Lyle Bickley's PDP-12 should have a bunch of material as well. Various versions of the manuals are at www.bitsavers.org/pdf/dec/pdp8/tss8/ -- Finding hardware capable of running the monitor will be difficult. RF08's were rare 20 years ago. All but the last versions of TSS/8 required either DF32s or RF08s for swapping, but DF32s are only 32kwords. Bob Supnik has TSS/8 running in simulation with SIMH.

It is a VAX 6000/610. 2 cabinets, approx 1000 lbs total weight. 2 CPU CMD Technologies DSSI controller ethernet capable comes with up to a dozen 2 gig drives( formatted) covers for the empty drive bays pretty sure that it is 208 volt single phase, although the drive cabinet has a 120v 30 amp twist lock connector on the cable. I dont know if this plugs into the CPU cabinets PSU or what. VMS docs and manuals The bad news, if that I try to keep it, I will lose the wife.

rack-mount Norsk Data ND100 available (Reading, UK)

by julesrichardsonuk＠yahoo.co.uk

We've just been offered a Norsk Data ND100 (running Sintran), which according to the 'offeree' is somewhat unusual in being a rack-mount version rather than the more typical cabinet variety. I doubt the museum can take it though as we're somewhat swamped in mini- class machines at present, but it's destined for landfill otherwise. Comes with full documentation and (likely) the controlling dumb terminal and a Genicom dot-matrix printer. Was working when put into storage apparently. The hard disk and floppy are also mounted in the rack (so no seperate enormous cabinets! :-) It sounds like the company may be hanging onto the rack it was put in (which probably makes it a little easier to manage, at least for most UK folks!) but that they may be disposing of the rack too. The machine's currently in Reading, Berkshire. There doesn't seem to be much info about these on the 'net - from what I gather they're 16 bit minis with a bit-slice ALU, and microprogrammed CPU. Anyone able to save it? I can put you in touch if so. cheers, Jules -- "We've had a lot of loonies around this place, but you're the first one who thought the sunrise was made out of stale beer.

Looking for PDP 11/60 Kd11-K Manual + TE-11 manual

Hi I'm working on my PDP 11/60's and need info on the processor set. The 1st board has LED's and thats a starting point if anyone knows the status of the the LED's would be helpful. Or a source for a on-line copy of the manual. ?? (kd11-k, m7872 1st board) The second item is a maintiance manual on a TE-11 tape drive. These look like a real challenge. ( Not sure if the TE-16 is close enough) I don't have either manual. Thanks, Jerry Jerry Wright JLC inc. 800-292-6370

PDP8/S internals

by gordon＠gjcp.net

Hi there, Perhaps someone who is a little more familiar with the innards of the PDP8/Ses can answer this... Are the individual flip-flops arranged like a shift register or a set of latches? In other words, when data is being clocked into a register, does a bit get put into (say) AC0 then bumped along until it eventually ends up in AC11, or are all the D lines of the flip-flops connected together, with each one being clocked in turn?

Storage Hazards

by marvin＠rain.org

In rummaging through classic computer stuff I haven't seen in a while, I saw several things that are definitely a problem. What other things need to be added to the list for collectors to watch out for? * Leaky nicad batteries that will "eat" the circuit board traces The early computers that come quickly to mind are the TRS-100, Lobo Drives Max 80, NEC 8201A, 286 and later motherboards, and S-100 CompuWatch Clock/Calendar boards. Any others that should be added to this list? * Subterranean termites (eating manuals and other cardboard/paper products) Fortunately, they had only mostly started on the cardboard boxes, and only damaged some of the manuals. I'm thinking that keeping the manuals in ziplock bags might be a good idea for any manuals that need to be packed away. This would also protect them from moisture if the boxes got wet. * Leaky storage areas leading to equipment and documentation being ruined. I've had quite a few books and manuals that had to be thrown away (nothing really rare, hard to come by, or valuable) due to a leaky roof where they were being stored.

[Simh] Request for Reccomendations - Telnet

by ron.hudson＠sbcglobal.net

Well, Kermit did the same thing as the two terminal programs.. Even though they say they are vt100 compatible, they still spew garbage and don't make the proper screen with vt50dpy... however vt50dpy running on a serial port on the host system works fine.. I just want to work at that terminal. what's funny is the terminal emulators work fine with teco/vt. I suppose vt50dpy makes more use of the terminal control codes.. Well, Thanks for the suggestions so far. :^)

Vector Graphic MZ 2.1 ROM needed

by gtulloch＠shaw.ca

Hi there: I have a Vector Graphic MZ machine in nice condition except that the Flashwriter II board seems to be broken, so using the Mindless Terminal is out of the question. I understand that the version of the Monitor ROM I have (either 3.1 or 4.0) does not support serial terminals so I'm dead in the water unless I can dig up a 2.1 ROM or write my own (with two young kids pretty doubtful I'll get to it real soon). Using a serial terminal is fine with me until I can get a new FWII or fix the one I have. So, I'm hoping someone out there has a Vector machine kicking around with a 2.1 ROM - I'd love to simply drop a new ROM into the machine and go, but a binary file will do or even a listing, I don't care. I'm happy to reimburse you for your trouble and materials, of course. Please reply or send me a note at gtulloch (at) shaw.ca if you can help me track this animal down, I'd love to get this MZ back in action. Thanks! Regards, Gord

PC BIOS Access

by marvin＠rain.org

I seem to recall that the IBM setup disk would work on other computers that required a setup disk. Another useful piece of information would be the ways to access the HD format routines on PCs. Somewhere I have a list that came from ComputerLand that gives the debug entry addresses for a number of controller cards. IIRC, the Xebex card required a sequence of debug instructions to start the format routines. > >> It might be interesting to have a list of ways that the BIOS gets > >> accessed during startup.

LaserJet IIISi reassembly

by mouse＠Rodents.Montreal.QC.CA

Some of you may recall that back in early September I wrote about an HP LaserJet IIISi that I disassembled and repaired after a capacitor fried. Well, even though I got the printer working again, I made a mistake. Just about the time I got it working again, I left on a month-long trip around the continent. (A few of you contacted me when I said I'd be traveling around. I didn't actually end up rendezvousing with any of you, and I apologize for it - I didn't realize how short of time I'd end up being. A month-long trip sounds like a lot, but it ends up being awfully short when there are five people/places to be visited, and some of the trips in between are multi-day trips.) Now, I want to put the printer back together, and there's the mistake: I didn't leave notes to myself on how it came apart and thus how it went back together. Would any of you happen to have a service manual that could guide me? I could probably figure it out eventually, but if I can save myself annoying mistakes, I'd like to. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

LGP-21 Flexowriter running...

by tomj＠wps.com

Sheesh, things just take so long to get around to... THe flexo is running fine now, except for the punch. It was of course just lubrication, the thing wasn't even dusty! The belts are even OK, though I suspect they won't last that long (old rubber). The punch and reader are sticky; the punch hangs, repeating the same character over and over (certain codes, "7", "A", etc) so it needs a little more lube in those areas. I missed a few linkages, hit those, and it improved. It punches fine, the reader works, but some timing linkage isn't dropping out, I'm sure it'll be fine. Whale oil or whatever it wants is long unavailable (nothing specified in the manual) so I'm using 0-weight synthetic motor oil. Motor oil is generally UNrecommended in old gear, but the new formulations (like synthetics) are pretty good and don't gum up. I used synth grease for the open gears. I've only got the offline Flexo cable, the one meant for the second flexo for offline tape preparation. I had to leave the second flexo behind, Ed wouldn't part with it (aargh). This one seems fine though. The cable is all cracked, like it's made of dried pasta. Slightly scary, but that's what circuit breakers for. There is a big electrolytic in this thing, a filter for the relay supply, but I said hell with it, if it vents it vents, but it seems just fine, lucky me. Of course it could be open and relays will buzz, but I'll find that out later.

FS: PDP-9 brochure

I was digging through some old papers and came across a 48-page advertising brochure for the PDP-9, in great condition except it's slightly "buckled" from sitting sideways in the box. It's called "PDP-9, The Serious Computer" dated 11/67. I can email pictures. Anyone interested? I have no idea if it's worth anything to anyone but if so I'd at least like to break even on the postage ;) thanks Charles

HP and Tandy Stuff

by bmachacek＠pcisys.net

Hi: I was just given the following items for recycle/salvage and thought I would check with the board here to see if there was any interest in these items before they go to the great recycle bin in the sky. 1. One HP RZ24-S PC hard drive. It has 3200D on the label, plus some other numbers. I was given this unit, so I can't guarantee that it works, but it looks to be in excellent condition. 2. One Tandy memory board with 8-1MB 90ns memory sticks on it. It has several numbers on it and I'll list a few. 1700 361 Rev. D, 0508 LEIU 7V, 1990 (year of manufacture?), P/N 870-9838, 889-9216200. Again I was given this unit so don't know for sure if everything is OK with it, but it also looks to be in excellent condition. Let me know is there is any interest in either of these items and for a few bucks plus shipping costs it can be yours. I will be glad to answer any questions on either of these items, just email me.

Diversified Numeric Applications (DNA)

by fordms＠gte.net

Greetings. I have a Diversified Numeric Applications MED16/Multiprocessor computer built in 1971, I think. It is a 16-bit machine with 16k of core memory, a 64track magnetic drum, switch console, analog input module, a serial MUX, paper tape reader. I used to have a removeable disk pack unit and drum printer, but they are gone. I do have an engineering manual with schematics, and a book of diagnostic program listings. I've had to 'repackage' the major components into a different 19" rack. The CPU, MUX, and DISC controller bays are wire-wrapped 9000-series TTL logic. It's very cool. I'd be interested in any information about this machine, and hopefully anyone else who has one. fordms(a)gte.net

I need to look at all the info for the memory crate though as the CPU still isn't happy (the run lamp's permanently on and we can't halt the CPU or toggle any data in from the front panel). All cards look to be OK in the CPU though, but I suspect there may be a problem with the memory... > I do not use the battery for MOS memory backup in case of a power failure > so I can not be of much help here. No problem - we're not intending on using it either; I just wanted to check that it should be OK without it. Time to do some reading this week! We did discover the limit of the power cabling in the museum room though - with the 11/34, 11/44, HP T500 and a few assorted terminals running we hit the 30A limit on the breaker and blew the power out to the room :-) Luckily we've found a few power outlets that are on a different breaker, so we can move some big stuff over onto that and spread the load. Still, adding the Marconi machine, Elliott 803 and the Decsystem 570 with the three massbus drives into the mix is going to make things interesting. The startup sequence for everything is going to be pretty critical... cheers Jules

8-track tape drives?

by bnansel＠verizon.net

About twenty years ago I bought a dual tape drive "mass" storage peripheral from a surplus outfit, United Products in Seattle. It was for a long defunct personal computer of the '70s. The computer (which I only ever saw in a few ca. 1978 ads in Byte) was an 8080-based system, and I think it was billed as having color video graphics capability. I don't remember the name of the company. Anyway, the distinguishing characteristic of the system was the tape drive unit used modified 8-track tape decks. That's right, 8-track *audio* cartridges, the kind people make so much fun of these days. The drive was housed in a blue metal enclosure with a black vacu-formed plastic bezel for the two "drives." It had a DB-25 connector on the back, though it definitely wasn't a standard RS232 interface. As I recall, the tape head assembly in each drive had four read/write coils, and it could move to one of two positions, up or down, thus giving eight tracks total. Presumably this was to decrease the "seek" time. I managed to trace through the circuit well enough to figure out how to write and read back serial data on tape, at about 2400 bps, as I recall. I had some fun hooking it up to a C64 in the lab to prove the thing was actually working. I kept threatening a co-worker that I was going to write a driver for the monstrosity to use on the lab's CP/M machines. He had just built a Slicer, a 80186 SBC that was popular for a few years in the mid-eighties, and the thought of such a kludge horrified him. Heh. I foolishly sold the dual tape drive and all my notes at a Seattle Robotics Society auction sometime around 1989. I've done some poking around on the web recently, but I have found zip about this machine. Has anyone ever seen one of these tape drives? I actually have a project that, perversely, requires something like this. -RLN

Hello Tony, I found a request on the internet today but the posting was made over a year ago. I wish I would have seen it then because I have this thing that I want to get rid of. It is a KSR33 Teletype with the interface converted to RS-232. It is still in working order but probably needs a new ribbon after sitting for at least 20 Years. I also have other vintage equipment that used to be connected to the teletype. It is an old PDP11-05 (DEC). Let me know if you are interested. Ken

It's not "--" but "-- ", and must be immediately preceeded and followed by a newline. It appears in RFC2646 as a "convention" -- but it's worth remembering that RFCs are not (mostly) standards either -- just conventions. There's a document called "son of RFC1036" which is the basis that almost all modern newsreaders follow, anmd you'll find the sig separator described in there. "son of RFC1036" was written, mainly by Henry Spencer, one of the original authors of RFC1036, because there are some errors/inconsistencies in RFC1036 which needed addressed; there's also a widely-used document called the GNKSA (Good NetKeeping Seal of Approval) where it appears as section 15. Both of these were the result of much discussion on Usenet and appeared because although the IETF produced many drafts of a successor to RFC1036, none were ever finalised. -- Pete Peter Turnbull Network Manager University of York

Ed> But, a 7 character program name?? Thought RSTS and the others Ed> were 6.3? The name was VT50PY, or DISPLY, or something like that. In V10.1, that program would do ANSI escape sequences if the terminal appeared to be a VT100 or above (i.e., a scope with XON support and no fill). But, judging by the sources, that wasn't available before V10.1. So you can change the code :-) or you can track down an xterm with VT52 escape support, or you could add it to xterm (VT52 escapes are pretty simple...) paul ------------- Ashley's stuff below (pardon me for leaving the large amount of the previous message up above. I know someone will scold me for that) I have VT50PY (yes that's the name) running on my PDP-11. And yes, that's the program that used to bring the system to its knees on weaker systems. I am out of town right now, but in order to make the thing work, you have to load the BASIC+ source for (I think) DISPLY.BAS and then APPEND VT50.DPY (or something like that - I'm saying this from memory and my memory is faulty). Then COMPILE it, and run it. If you want to allow non-privileged users to run it, compile it to <232>. It uses the VT50/VT52 escape sequences to clear and update the screen, so you need to do VT50/VT52 emulation. It does have a switch to allow you to use 24 line VT52 mode vs the standard 12 line VT50 mode. I'll check on the details when I get back home. Sounds like you need to make sure your terminal emulator is doing VT50 or VT52 emulation. It runs fine on my real VT52s or on my telnet sessions with VT52 emulation. Ashley

VCF 7.0 on November 6-7

by vcf＠siconic.com

Vintage Computer Festival 7.0 Saturday, November 6 through Sunday, November 7 Computer History Museum Mountain VIiew, California Since the last VCF, the trials and tribulations of daily life made their inevitability painfully attendant: bills came due, accidents happened, bad days at the office were had, arguments broke out, and the morning paper was thrown into the sprinklers yet again. Woe is us! But lo, a bright and shining beacon of nerdilicious salvation is on the horizon and draws nigh. The Vintage Computer Festival returns! Vintage Computer Festival 7.0 is right around the corner, taking place on November 6-7 at the Computer History Museum in Mountain View in (still) sunny California. Flights are cheap and so is the admission, so you have little excuse to stay home cramped behind your computer trying in vain to craft that perfect Google search term. Just put all that nonsense behind you and join us for some fanatical Festival folly! We are honored to once again have the Computer History Museum as our sponsor! And as always, we bring you yet another wonderful line-up of speakers, exhibitors, and special events, including a 30th anniversary retro- spective of Maze War, the original "first-person shooter" videogame, plus so much more! In fact, we're planning so much for this year's event, it might possibly be even too much! Some of it we can't even mention yet because we're still in the middle of planning it. So come on out and watch us put on a gargantuan geek gala guaranteed to gasify your gall bladder...either that or watch us crash and burn in spectacular style. Either way, it's sure to be entertaining! Exhibitors Wanted!!! One of the best ways to enjoy the VCF is by participating directly. Be an exhibitor!
