I'm *ALSO* new to this list!

by marino13＠btinternet.com

Lucky person! I only ever "rented" a Veccy from a local electronics shop for a few days at a time, me being a devout G7000/Odyssey owner at the time (and heavily into LCD handhelds/tabletops - as am I still!). Keeping your original machine is SO much more rewarding I think - getting something back that you loved as a kid but sold is cool, but digging your ACTUAL machine from the loft is way better. I still kept my original "Ball" Nintendo Game n Watch (the first on out of the series) so thats pretty special to me. And my first ever Pong! The Lightpen and Imager (and the art cart) are really sought after - look after and enjoy!!!

M2333 and M2382 drive questions

by rdd＠smart.net

Greetings, Yesterday, thanks to Tim Shoppa, I collected some 8" SMD drives: a couple of Fujitsu M2333 (337MB) and M2382 (1GB each!) drives and an Emulex SC03 controller. Its my understanding that I might not be able to use these large drives with an SCO2 or SC03 controller, so, I'm wondering what I need in order to use them with a PDP-11/73. -- Copyright (C) 2001 R.

VMS setup

by Alan.Pearson＠cramersystems.com

I'm looking around for a VMS setup at the moment, but space is tight(as always!). Can anyone offer suggestions for a smallish (desktop/under desk) machine that's suitable for running VMS on? My only experience with VMS is 10+ years ago, version 4.something I think. It ran on an 11/780 cluster, kind of out of my league :-) Any suggestions, pointers to websites etc? TIA Al.

Whats you oldest computer

by aknight＠mindspring.com

Depending on your definitions, the oldest computer I have is a Mathatronics Mathatron model 4-24, serial number 00133, circa 1964. While this machine only deals with numbers, it has multiple storage registers, is programmable, and can do decision-based branching. It also had Input/Output capability. I also have a Mathatron model 8-48, which dates from 1965 (it has more memory). I've been in touch with one of the designers and the design dates from 1963. Unfortunately, neither of my machines is functional. Read all about it on the Desktop Calculators section of my webiste at http://www.calcmuseum.com The oldest full-blown computer I have is a HP2100S. classiccmp(a)classiccmp.org wrote: > Hello All, I was just curious to know what was the oldest computer any of you own.

Bought for $3 - MPX16 plus needs

by rcini＠optonline.net

Hello, all: Well, VCFE wasn't so bad :-) I bought a Ciarica/Byte MXP16 8088-based PC-clone motherboard which was the subject of a series of articles in Byte in late 1982 and early 1983. I have the first two parts of the series (11/82 and 12/82), but I'm missing the 1/83 issue and possibly later (I don't know how many issues the article ran). For 1983, I only have beginning in July. If anyone has the remaining issues (except Sam -- based on the photos shown at VCFE, I'm sure that he couldn't find them :-)) containing articles, please contact me off-list. Thanks a lot.

I've seen it happen already (although that was an 802.3 vs Ethernet II issue, and the later rev of the h/w was fixed). But you are right, noone tests against anything other than IP(v4) and noone designs new protocols that easily accomodate anything that is not IP. Antonio

altair 8800

by lemay＠cs.umn.edu

Dumb question, but what might an Altair 8800 be worth these days? A friend is getting one from his father, who got it around the end of 1975. He asked me about sources for manuals and documentation, plus sources for boards to upgrade the system. Further questioning revealed that he wont get the unit until he travels back to visit the parents, and that the unit apparently has a 256 byte memory. This small scrap of information leads me to think this could be an original kit built system, with the original memory and probably hasnt been upgraded. If so, it could be a very dumb thing if someone who is clueless decided to upgrade this system, when he may actually have quite the collectors item in original condition on his hands... I'll pass along any information, or sources of documentation or scanned in manuals, that anyone can provide. -Lawrence LeMay lemay(a)cs.umn.edu

Font used in d|i|g|i|t|a|l logo?

by Antonio.Carlini＠riverstonenet.com

If you look at (almost?) any document produced by Digital in PostScript format, somewhere near the beginning you should find the part that does the Digital logo. Usually there is a long comment describing who designed it, when it was done and how it should (and should not) be used. At some late stage in its life, Digital decided to revamp the logo. For a mere $500K (or thereabouts IIRC) a consultancy recommended some major changes. The round dot is the most noticeable. For $400K I would have been happy to provide equally valuable advice ... as usual I was in the wrong place at the wrong time :-) Antonio

available: Q-bus SCSI controller

by wrking＠dadaboom.com

I have a Distributed Logic Corp, SQ716A Rev J, differential (high voltage) Q-Bus SCSI disk controller that I'm willing to part with. I've tested it by booting into it's internal monitor on a uVAX (and that works), but I don't have a differential SCSI disk to test it with, so I guess it's as-is. Things I'd be willing to trade for (all or part). 1.) One each, RL02 unit select plugs 2 and 3. 2.) DEC BA123 cabinet kit for a RLV21 (RL01/RL02) disk controller. 3.) Rear rack mounting brackets for a DEC BA23 (5.25 inch rack mount uVaxII chassis). I have the two long side rails, but there is a small bracket which attaches each side rail to the rear mounting bracket in the rack cabinet. 4.) Some number of RL02 packs. Let me know if you are interested... Bill

Seeking instructions for setting up a MAG MX17 monitor

by ethan_dicks＠yahoo.com

I got this 17" monitor from the local uni surplus recently. What caught my attention (besides the $10 price) was that it had an HD-15 VGA connector, a Macintosh 15-pin connector *and* BNCs, and a 2-line LCD display on the front. I figured it was worth the risk since with no cable attached, I couldn't test it there. It passed the crackle-hum test on the bench and I brought it home. Random button poking does not seem to be a useful way of guiding it through setup. There's a row of 8 numbered buttons (also labelled for changing width and position) and a menu button. Additionally, there is a toggle switch on the front for "BNC" vs. "DSUB" and for "user settings" vs "presets" I can get a stable picture of a laptop in its BIOS setup after a fashion, but it's only when I'm in the middle of certain operations on the monitor frontpanel. I can't get it to stick. The monitor LCD says that it's 640x480 @ 70Hz. If I get to the Phoenix spash screen telling me nifty things about the innards of the laptop prior to booting the disk, the MX17 tells me that the sync is "SuperVGA 800x600 @ 60Hz" which I guess makes sense even though it's a 80x25 character display because the laptop is nominally 800x600 unless you hit "Fn FONT" to kick it down to non-stretched pixels occupying 75% of the entire screen. It also matters if the CRT/LCD mode is one or both; that seems to affect what the external scan rate is (also not unexpected from earlier fiddlings with Solaris on this laptop - it was a bear getting the settings right for X on the LCD). So... ramblings aside, I'm looking for a setup guide for how to tell the monitor what to expect is coming in. It has 8 user-definable modes and I can't figure out how to tell it what the definitions are. I did a quick Google search and only came up with reseller sites and a couple quick mentions in an SGI Indy FAQ and a mega list of what scan rates are supported by which monitors for XF86 - less than 50 hits on MX17 in all.

BRATS hamfest...

by wh.sudbrink＠verizon.net

Well, I got up at 5am to go to this. Got there at 6 when the gates opened. Attendance was light, probably due to the impending rain. There was no rain at 6 and there were about 30 tailgaters. Not much of vintage interest, some Sun boxes here and there, a few old Macs and one guy with a couple of Atari boxes. Got what I thought was a good deal, 4 2Gig wide SCSI drives for $3 each. Unfortunately, now that I've got them home, I see that they are HVD. Does anyone have a PCI HVD SCSI controller that they might part with for a reasonable fee? Anyway, the rains came at about 7:15, some tarps and tents popped up, but a lot of guys just packed up at that point. Peeked inside the indoor space, which was to open at 8, looked like a run of the mill clone show with some radio vendors thrown in... so I called it a day. Oh well...

Mounting a SCSI Device in a BA-123

by tsmurphy＠addr8.addr.com

Has anybody ever mounted a SCSI device in a BA-123? 1. I tried to install a standard half-height 3.5" SCSI drive into a BA-123 system (MicroVAX II). Basically, I bought a little 3.5"->5.25" adapter, and then screwed the adaptor into the sliding base where an old RD-54 lived. I found the solution unsatisfactory; the adaptor's screw holes did not match up with the sliding base, and it generally feels fragile. Is there a better way? I am envisioning some sort of "cage" which has the form factor of a full-height 5.25" drive, with mount points for a 3.5" drive (or two). Does such a beast exist? 2. Has anybody ever installed a half-height internal CD-ROM (or tape drive) in a BA-123 system? This would be really sweet (sure beats an external one!), but would it mount nicely, and would it be possible to cover up the half which isn't being used with a nice faceplate? 3. Is there a decent internal SCSI cable which can be used in a BA-123? I only have a couple of boards in the system, so my SCSI controller is all the way in the front of the backplane (back of the system), far from the disks, and just barely reaches the disks. Is it possible to get one with some slack, and still have several disk connectors? Thanks, Terry

Way OT: vacuum pumps

by mcguire＠neurotica.com

Hi folks. Apologies for the way off-topic message, but this is the gang with the most varied experience that I can think of. Does anyone know anything about, or have docs for, a Varian M200 oil diffusion pump? Specifically, I need to know if there's a way to check the oil level without removing the pump from the vacuum chamber. -Dave -- Dave McGuire Laurel, MD

Free: DEC/PDP & Sun Stuff

by mrbill＠mrbill.net

FREE STUFF! For pickup (only) in Austin, TX. I'm available any night of the week after 6pm. PDP stuff still left: Two RX01 dual-8" floppy drives. David W. didnt have enough room in his van after the 11/60 and other stuff was loaded, so they're first-come, first-serve. Sun stuff: 4/690MP VME cardcage and blower 6 x 2.1gig 5.25" FH HVD SCSI HDs Lots of diff. external cables, etc 3 x rackmount drive "trays" w/power supplies 1 x holds the 6 drives above 2 x holds 3 1.3gig IPI drives 6 x 1200W power supplies for the VME cardcage (lots of extras!) Other stuff: Tons (6-7 at least) of older 386/486/K5-based motherboards, RAM, older CD-ROM drives, video cards, etc. Enough parts here to build at least 3-4 working systems, I'd say. I've also got a custom 486 in a Bell-logo'ed custom-built rackmount case that has/had windows 3.11 installed for some kind of CO switch management. The "rules": 1. No making any of this stuff into 'wall hangings'. Well, you can do that with the PC stuff, but not the Sun or DEC stuff. 8-) 2. You have to give it a good home or give it to someone else who will. 3. If I dont get any takers on the VME cardcage, someone who comes to get something else has to help me toss it into the giant construction dumpster in the front yard. I narrowly avoided certain Doom via Wife when David showed up to take some of the larger PDP stuff off my hands today. 8-) Email me if interested in anything.

IBM and pantyhose (was: Pocket protectors)

Hmmm, I wonder... does IBM have have any rules stating where employees are supposed to wear them, or do the rules just state that one is to wear them? There are multiple possibilities... over one's arms, head, around one's shoulders, in one's sportscoat pocket in place of a handkerchief, etc. Working at IBM must be rather interesting... the more rules, the more poorly defined rules there usually are which one can twist around to make the workplace environment more interesting. -- Copyright (C) 2001 R.

The drives have been "self-dismantling" over the past couple of decades. In particular, the glue that holds the optical gratings has - in every case that I've seen - come undone. I've managed to make a few good PerSci's by combining parts from broken ones, at least. But they're amazingly complicated drives. (As well they should be, considering how much they cost back in the 70's - you could buy a brand new car for what 4 PerSci's cost.) Even on the broken ones there's a huge assortment of electromechanical parts still in place. How many other 8" floppy drives had motorized loading/ejecting? (I know that some Shugarts and NEC's had the option of ejecting via a solenoid, but I'm not counting solenoids here. And I'm certainly not counting the drives that would, if you loaded and unloaded the head often enough, vibrate so much that the door popped open! ) Tim.

A few new finds

by jrkeys＠concentric.net

Picked up a Wavetek waveform generator model 159 yesterday at the thrift and it works great ($3.95). also picked 6 really nice mousepads for that part of the collection at the same thrift. Picked up some in the box 2600, Genesis, and Odyssey game cartridges from 80 cents to $2.99 each. I know they are not 10 years old yet but has anyone else notice the number of playstation one's at the thrift's lately ? They have been priced from 3.99 (console only) to 14.99 (complete systems). New games (unopened) have been $1 to $13 dollars at the thrift's here.

It's been a good day. Picked up a couple of new items. One, I picked up an Atari Portfolio with spare 128k and 64k memory cards and the PC Card drive from someone in Germany in exchange for some DVDs I produce. It near mint condition it appears. Doc is in german but I can understand enough to get me through. Now to go hack some ATMs. :-) The other cool item was the first dual processor BeBox! First in this case as in the first one off the assembly line. Can't wait to get this home and hooked up. Of course I don't think that falls under the 10 year rule. ----- "What is, is what?"

Clip the pocket protector on with alligator clips attached to red and black wires... this will have the advantage or providing one with an emergency supply of spare test leads. :-) > > This just got me to thinking.... > > How did pocket protectors become associated with 'computer > >enthusiasts'? Ok, I see it's time for the Pocket Protectors 101 course... Since I wore one back in college during a time when I was taking a lot of math, science and electronics classes, I'll take a guess at answering this. Back then, math, engineering, electronics, etc. students were the most likely students to be computer hackers. Such students have a need to carry a wide variety of pencils and pens, etc. in their shirt pockets; for example, I typically had fine and extra fine point Scripto (?) "click" pencils (press on the little chrome tab that holds the eraser and more lead comes out), a retractable erasor, a couple of different pens and perhaps a felt-tipped marker or two. Pocket protectors are made of reasonably thick vinyl and lessen the chance of one damaging oneself, or one's clothes, if one fall, bends, or bumps into something the wrong way --- that is, in such a way as to get stabbed by the writing instruments in one's shirt pocket. Pocket protectors also keep one's pocket from getting dirty from lead and pens that might leak ink; in addition, they protect the shirt pocket >from the wear of clipping and unclipping writing instruments to and >from it. > > And how many here have wore a pocket protector on a regular > >basis in the past? > > What the hell is a pocket protector? You've never heard of a pocket protector before? Amazing. Perhaps it's a language translation thing, and they're called something else in your country. Over here, they're very popular. A pocket protector, as mentioned above, is a reasonably heavy vinyl lining for a shirt pocket, into which one places writing instruments, etc. Refer to figure 1 below for an illustration of a pocket protector. The pocket protector is represented by the asterisks; the straight lines represent the shirt and pocket. | |* |* |* *** |* *|* |* *|* |* *| |***| +---+ fig. 1 ASCII cutaway representation of a pocket protector. -- Copyright (C) 2001 R.

Coax. How dumb can it get. I'm not quite sure what you're saying. If you're saying that the earliest bridges were dumb repeaters, you're wrong. The definition of a bridge is a layer 2 device that passes traffic according to the destination addresses contained in the packets. If you're saying that the way a bridge works is to learn where addresses are, and until it knows, it will pass packets everywhere, that's true. Even with old bridges, you wouldn't be able to see *all* the network traffic because the bridges would split the net into different collision domains (that's what they are for), so the only traffic that would go everywhere was broadcast traffic. You wouldn't even see all the broadcast traffic if you had a router or two in the system, and there's nothing new about that either. -- Pete Peter Turnbull Network Manager University of York

I neglected to list this as available the other day. Memorex-Telex 85PS server case. I think this is a standard Intel server design, not ATX, and not AT, However. It is sort of in between looking to me. I have also seen this case used by Zenith for one of there Z-Servers. It'll hold about 8 3.5 inch hard drives. It also has a floppy drive plus space for a tape or cd-rom. It is new. I have all the paper work, cables, etc for it. It's free, but you pay shipping. It's in my living room, and will be recycled if no one wants it. Chad Fernandez Michigan, USA

Hello, all: For those interested, I seem to have found at home another copy of the history of the Apollo guidance computer book by Eldon Hall, speaker at VCFE. I purchased a signed copy from him today because I thought that I didn't have a copy at home. Surprise! So if anyone is interested in the *unsigned* copy, I'll let it go for $35 including shipping. I paid $45 for the signed copy and bought my first copy on Amazon for about $55. Again, interested parties please contact me off-list. Thanks.

Booting A PDP-11/23

by univac2＠earthlink.net

I recently found a PDP-11/23 (Model 11C23-FE) at Goodwill. It is in a tall slim tower style enclosure, has a dual 5.25" floppy disk drive, a hard disk, and 1024KB. It passes the memory test, and trys to boot from "DU0". The light on the hard disk comes on for a few seconds, and then I get the message ERROR UNIT DU0 ERR 13 DRIVE NOT READY WISH TO REBOOT [Y,(N)]? So is something broken, or am I just doing something wrong? Any help is greatly appreciated. Thanks, Owen

Do either of the floppies or their lights become active???? If they are it's looking for bootable media and there is none. The other possibility is the drive(s) is/are disconnected or maybe plain DOA. Allison

Free in DC area: Fuji SMD drives

by CLASSICCMP＠trailing-edge.com

I've got 5 Fuji 8" SMD drives (M233x and similar) just inside the DC beltway (I-495) available immediately. You pick up only; I will not ship these (weight with power supplies is 35-45 lbs each). They all worked about three years ago, the last time I fired them up. Anyone hauling them away also gets my collection of Emulex SMD controllers and Fuji SMD manuals, and the rack mount slides/trays, and whatever else I feel like making you take. Also available are some 8" Pertec voice-coil floppy drives, in "parts only" condition. Manuals and some Pertec-specific test equipment are available too. Again, you-haul. Email if interested; first-come, first-served. Tim. (shoppa(a)trailing-edge.com)

Free in Austin, TX: PDP-11 equipment

by mrbill＠mrbill.net

I've got the following PDP-11 equipment free for pickup in Austin, Texas. David Williams from Houston has first shot since he is coming to pick up some uVAX-IIs, but anything else left is fair game. If you come get something (email me first!), you have to promise that it wont be scrapped or the front panels sold on eBay for some rich CEO's wall collection. I'd like it to all go to good homes where it will be appreciated. (god, I sound like an animal shelter) - PDP-11/60 and UNIBUS expansion cage (and some maintenance printsets) - two RX01's - one RK05J If anyone is interested, please email me. This stuff CAN NOT and WILL NOT be shipped - i cant even get some of it out of the crate I got it in. 8-( Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

building a PDP11 from the things you find at home

> Don't you think it strange the bidding went from $50 to $600 in one bid? > When $50 seemed to high? > I smell a wumpus, or a rat! I've seen this happen a couple of times. Someone that really wants something will put a very high bid in, knowing that no matter what happens the eBay bidding mechanism will automatically up their bid. Someone else that really wants the same thing will then come along and put in a very high bid. This causes the bid to automatically shoot up to the lowest of the high bids. Fortunately I don't bid this way. I only bid what I'm willing to pay and that's it. -- Eric Dittman dittman(a)dittman.net

OS/400 anyone?

by optimus＠canit.se

While at the junkyard yesterday, someone had dumped a bloody lot of QIC tapes. The original labels said "AS/400 SYSTEM SOFTWARE" and such things. Great, right? But then there were additional labels saying such things as "H:\ NT BACKUP". Arrrrgh! They're reusing OS/400 tapes for such things? Bastards! -- En ligne avec Thor 2.6a.

Importance of Grounded Power?

by tsmurphy＠addr8.addr.com

I recently got an old AlphaServer 4/275, and it worked for a while, and then after I moved into another room, and it stopped working. I only have one or two grounded outlets in my apartment, so I had to hook it to a non-grounded one (via a surge protector, plugged in with a grounding adaptor). I'm not sure if it's coincidence, but that appeared to kill the AlphaServer (the power supply, to be precise). Is it technically possible for non-grounded power to be able to kill a system? In general, what type of hardware will require real grounded power to function? I have a whole slew of PC's, for example, using non-grounded power outlets without a hitch, so is this only going to be a problem for industrial equipment, like AlphaServers? Also does anyone know where I could get an AlphaServer 4/275 power supply for cheap? Thanks, Terry

Logically, the innards of the hub are the bus. The ports are the taps. Then, since the stations connected are typically some distance away, you use an appropriate technology to get the cable to them, and that's why there are additional transceivers (one on the host card, one on the hub port) to drive the signal over a resonable distance. It certainly changes the physical layout of course (short bus long drops instead of a long bus with short drops). > Now 10/100 switches really screw with it.

Hackers: Computer Outlaws revisited

by vcf＠siconic.com

I must say I was a bit surprised at how well done the show was. It wasn't over-sensationalized at all. On the contrary, I thought it was very well researched and did a good job of telling the stories and explaining the technical stuff. I was glad that they had more quotes from Jonathan Littman than from John Markoff. Littman told Mitnick's story closer to what really was going on, while Markoff stuck to his agenda of vilifying Mitnick, which he's spent the better part of the last five years of his career doing. Markoff is the kind of reporter I despise; one who attempts to make the news or mold it in his view rather than simply report it. But I don't think Mitnick's story is as rosy as he paints it either, and I think he's spinning some revisionism on it. He's certainly got some skeletons in his past that he's not owning up to. Anyhoo, Draper's story is pretty much how I've heard it told before. He really was just an unfortunate fall guy of sorts. The warehouse where they filmed Draper is where my computers used to be stored (well, a few still are, I'm not quite done moving yet :) There were some shots of me typing on an Apple ][ (you may have noticed the "CALL -151" on the screen at one point :) but you couldn't tell who it was, just hands. The display of 1's and 0's that showed periodically was generated on an Apple ][ as well (that is, by far, the acme of my career). There was also some other stuff, like 6502 assembler scrolling by, and of course the computers they showed rotating were all mine ;) Well, that was fun. One to the next show: I'm providing some Altair footage for a National Geographic special on computer history. I'm also in the process of developing a documentary on the F14 flight control computer, but that's a slow-going affair. Once the VCF's are over for the year then I hope to kick that up into full gear.

need help with an old ST-251 MFM drive...

A parallel port ZIP drive is very handy for this sort of thing. Easy to setup; in your case I'd format a disk in the old PC (360K), take it to a newer PC, SYS it with 6.22, put the files on it for the ZIP drive, and boot it on the old PC. The parallel ZIP only needs a 1/2 dozen or so control files to work. a:guest (assigns ZIP to drive D) xcopy c:*.* d: /s /e (put it on the floppy when you sys it) It make take awhile. Go have lunch.

ID these boards (pictures)

by mrbill＠mrbill.net

Check out http://content.sunhelp.org/boards/ Anybody know what these might be out of? No company name/markings that I can find. About the size of a modern PC motherboard, maybe a little smaller. They DONT look like DEC boards to me, but I may be wrong. The "levers" on each board to remove them are two different colors - one white with a label, one colored (I guess to color-code installing the boards). Each board has two card-edge connectors to plug into a backplane, and some have top-edge connectors (cables, etc, I would guess).

need help with an old ST-251 MFM drive...

by CELang＠worldnet.att.net

Well... If it were me, I'd just hook the things together modem to modem (or serial port to serial port as the case may be) and send everything over using terminal software. Procomm was what I used on my olde '286 and XT; Hyperterminal for my Pentium machine. Craig -----Original Message----- From: Daniel A.

I'm currently trying to get the DTC controller to work in an old EISA 486 with a 1992 AMI BIOS, but I keep getting a "HDD Controller failure" message. I've tried it both with the controllers BIOS enabled and disabled. If the BIOS is enabled, it puts up a message saying "1 hard disk" right before the other error - this is the same message I see on the PC right before it starts booting. > >So I know the controller itself is "working", but it's not being recognized by the BIOS.

building a PDP11 from the things you find at home

You would mention that... I've got a Dell PowerEdge 2400 sitting three feet away that's slowly robbing me of my hearing... it has a "slow mode" but since airflow around the unit is a problem, I don't feel safe using it... so it stays set on "hurricane"... -dq

That could be an 'interesting' project.... I'm not sure what would qualify as "real" to you... would it have to be a machine built from the original schematic prints? Or would a re-implementation using modern devices (e.g. FPGA) qualify as "real"...? -dq

Apple ][ boards -- what have I found?

The Tube is the only 40-pin connector on a Beeb. -- Pete Peter Turnbull Network Manager University of York

Vintage Mac TOPS Flashbox

by kapteynr＠cboe.com

John: You wrote: "People who can help Fred should reply to his address.", but I can't figure out this address. Anyway, I noticed that one of the big electronic surplus places had tons of TOPS network stuff ~5 years ago. I think it was Alltronics in San Jose, but I am not sure. -Rob ----- Original Message ----- From: +ACI-Frederick Scholl+ACI- +ADw-freds+AEA-monarch-info.com+AD4- Sent: Friday, July 27, 2001 1:58 PM Subject: Vintage equipt Dear John, I am trying to find vintage mac networking equipment, specifically TOPS Flashbox and TOPS Flashcard. They were used for interconnecting Macs and PCs around 1991. Any suggestions would be appreciated. Regards, Fred Scholl ----- Original Message ----- John A.

IBM-PC keyboards

by liste＠artware.qc.ca

I picked up an IBM keyboard at the Village des valeurs on saturday. It has nice tactile feedback, no vanity keys and takes up less desk space then my aged Keytronics. Cool. However, it "doesn't work". When I plug it in and start the computer, all 3 leds go on, then NumLock goes off and nothing responds as I would expect (caps, scroll, del to get into bios, ctrl-a for adaptec scsi monitor) I was under the impression that there were 2 types of keyboards for clones: PC/XT and AT keyboards. This keyboard has a PS/2 style miniDIN-6 connector (though I now notice it doesn't have the rectangular plug in the middlish that my other keyboards do), so I assumed it would be AT and therefore compatible with modern motherboards. No luck :( Looking on the bottom I see : Part No : 1395300 IBM ID No : 2117313 Date : 12-05-1992 (C) IBM Corp. 1984 Plt. No. : WP1 Model : M2 Made in USA [bar code] 1395300112117313 So, do I have a defective keyboard? Or is this not even a PC keyboard but for some other piece of equipement? -Philip
