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 ]

Difference 23512 and 27512 Eprom

by rimmer＠xs4all.nl

Hi, I know very little about electronics and eproms so this question might be really easy. 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?

by jfoust＠threedee.com

I apologize again for cutting you off during our phone conversation... I was expecting someone and they'd arrived. And googling about my PC-1201 helped me remember that it had two button batteries for backup of the memory... and I remembered that I hadn't removed them in 15 years or so. They were a bit corroded but no damage was done. - John >Date: Mon, 18 Oct 2004 09:37:57 -0500 >To: news(a)computercollector.com >From: John Foust <jfoust(a)threedee.com> >Subject: Re: museum phone number? > >At 08:39 PM 10/16/2004, you wrote: >>What is the phone number for the Jefferson Computer Museum? >>I'm the editor of Computer Collector Newsletter, a weekly(-ish) e-mail >>publication for the hobby.

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

Wanted: IBM hard drives for PS/2 Model 30

Hello all, I have two IBM PS/2 Model 30 computers in need of hard drives. The IBM part number is 72X7568, and is a 20MB drive. This has IBM's proprietary interface that includes power and data on the same cable. If anyone has one or two of these drives available, let me know off-list, and we may be able to come to a deal...

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.

Rescue...

by david＠dynamicconcepts.us

Looks like I may be doing a rescue of the following in Eastern Conn.... 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. Without debating the merits of this trade, let me just say that it will not be good financially <grin> So....What do I do?????
