HP3000/2000/1000 emulators?

by jlwest＠tseinc.com

in case you missed my post on classiccmp, Jeff Moffat wrote an emulator for the 2100. Don't recall the URL, but search yahoo & such for 2100 and you should find it.

HP 2000 Time Shared BASIC Memories

Right next to it was our other high school machine, a PDP-11/03 running RT-11 with TSX+ extensions. It's name was DUEY. (I have already gotten several machines of mine up and running RT-11 with TSX+). Gee - I wonder what they would have named a third system if we had it ;) Jay

HP 2000 Time Shared BASIC Memories

by jlwest＠tseinc.com

Rick; Great to hear some stories about my personal obsession - TSB. I know of only one TSB system still up and running - a friend of mine in CA. I still don't have mine up but I'm getting awfully close - all I need is a 2748 paper tape reader and a 12920 mux set. I found the paper tape reader but they want $650 for it. Pound Sand I said ;) Yes, there is an emulator for the 2100 series cpu. Check out Jeff Moffat's website. Don't remember the URL, but search yahoo & such for "2100" and you'll find it. He has an emulator that runs on dos. It is supposed to run on Unix, but - it has some real problems with FreeBSD. Another user on the list here was kind enough to fix it up for freebsd and send me a diff file. I've got it here if you want it. The emulator supports most of the 2100 instruction set (or subset of the 21MX M series - however you look at it). I haven't yet dug into the emulator - eventually I will for sure - but for now I'm obsessed with getting the "real thing" up and running. As I recall from a quick first blush look - the emulator didn't have any real support for emulation of the select code addressed devices - ie - no 13210 disk controller, no 12920 muxes, etc.. but jeff has done a lot of great hard work on it so it's a fantastic starting point. On a side note - I'm still waiting but recently reconfirmed that I'm receiving a complete SOURCE code listing for TSB (2000F varietry) both the I/O and system processor portions. Then we can not only run it but change it (and perhaps fix that NAM-, issue <grin>). Another person recently offered me a copy of the "cupertino gold tapes". This is source for every version of TSB, RTE, DOS, etc.... That isn't a firm deal yet but you can imagine my anticipation if it works out :) You also queried about if HP still made TSB available in any form. I've got some pretty close ties to HP - the answer is a resounding NO. I even went so far as to plead my case to their Historical Archives administrator. There's not a shred left. But eventually I DID find some load tapes (both punched and magnetic). See ya!

Travelling in some other EU countryes, I've noticed that few household installations have "SAFETY DIFFERENTIAL-CURRENT BREAKERS" (here in Italy are called "Salva-vita=Life-saver), and also from these messages I learn that 220v are used also in the US (surprise) for heavy applications, but again nobody from both side of the ocean refers to the presence, safetiness, of these devices that here are used and mandatory from 15-20 years. I would like to hear from you all what's the situation there, if they are diffused, you use them, are considered (toghether with earthing) enough to avoid danger situations.

Amiga 1000 sidecar

by PeksaDO＠cardiff.ac.uk

As the Amiga 1000 has been brought up .... Sometime last year I acquired an Amiga 1000 (Built Feb 1986) and an Amiga 500 but only recently have I got arround to playing with them. The 1000 came with a sidecar unit and by now you should have guessed what I'm about to ask .... I've got the 1000, I've got the sidecar, I've got kickstart and workbench but I haven't got the software required to access the sidecar from the amiga. The sidecar has 448K of memory (256K on motherboard (with space for another 256K) plus 3x64K on a ISA card (with space for another 64K) and a hardcard (which hopefully has an amiga partition). Anyone out there have this software or know where I can get it from, Ta, Doug.

Puyallup event

To answer earlier questions... Yes, this is an indoor event. Two floors worth. I've not been to TRW in years, but I have attended Bay Area swap meets such as the Livermore and Foothill events. For those that have done the same, I would guess the size of the Puyallup event as about half again as big as Livermore (conservative). -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Puyallup swap details

by kyrrin＠bluefeathertech.com

The Puyallup swap meet takes place the second Saturday of each year at the site of WA's annual Puyallup Fair (a livestock and amusement thing). Since it is sponsored and put on by one of the local ham radio clubs, it is not dedicated to computer hardware, though I have definitely seen 'classic' stuff show up there. It's primarily electronics: Communications (radio), along with test gear. I regret that we only have room at the house for a single guest (John), and that I have only one additional admission tag to cover him. Anyone else who wants to come, feel free, but you'll be on your own for lodging. The event actually starts Saturday the 13th at 09:00. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Numerix VAX manuals

by rigdonj＠intellistar.net

I picked up a BIG load of manuals today. A lot of them are manuals for the software to accompany the Numerix MARS-432 Array Processor that (I *think*) was used in the VAX 11/760. The books are dated 1984. Numerix is Numerix Corporation located in Newton, Mass. Is anyone familar with this stuff? Anyone need the manuals? Joe

Packing and Shipping

by jpl15＠netcom.com

I might come to regret this.... ;} I will be in the Seattle, WA area the weekend of the 13th. I will be inflicting myself on the kind hospitality of Mr. Bruce Lane, and visiting the Puyallup Swap Meet. I am flying there in a plane and returning in a 12-foot truck, which I think will only be partially loaded. So.... If anyone has something truck-able in the Seattle area to be delivered into the Los Angeles area.. p'raps we can work something out. The governing parameters are: it fits in the truck, it gets on the truck Saturday the 13th afternoon or early evening, and it gets picked up in LA at my house, or can be easily transfered to my (smaller) pickup truck and delivered to you in the LA region for a suitable bribe. I am driving straight through Sunday, so no intermediate stops are planned between There and Here. Also: items of interest to classiccmpers only, please. This was inspired by Jay West's idea of forming a network of folks to 'stagecoach' jun^H^H^H^H equipment accross the country. Let me know via private e-mail. Cheers John

It is much more like the System Management Mode of the recen <x86 processors (late-486-era to present). Cant speak for the kickstart code. Slushware is the softloadable diagnostic, boot and system service code for DECmateII/III systems. the code provides terminal and keyboard emulation and some device emulation. Due to the characteristics of the CMOS PDP-8 (6120) the device has the nominal 32KW of system space as 8 4k pages and also a duplicate space that is special in that it's assigned it's own unique front pannel interrupt. That address space and interrupt BTW is something a real PDP-8 does not have. Due to the way it's structured you can sort of use it as system space for things like rom, rom loaders and special purpose handlers. Also unique to the DMII/III is that IOTs for 603x and 604x (TTY IO on nominal -8, a few others as well) are trapped to CP space handlers for emulation of display and lk201 keyboard. It can be considered on other micros as boot and device code that runs is special banked memory. It is not however microcode. Allison

attention MITS fiends . . .

by edick＠idcomm.com

My problem stems from the fact that there are WAY too many things for me to handle at once, Sam. You wanted me to pack the stuff and have it shipped via an economical method but which required me to package and haul the stuff some 45 miles to the airport area. I just haven't the resources (personal) or the time to do all this under my present circumstances. What's more, I've had to move TONS more stuff from the basement to the covered storage outside, and it's pissing my neighbors off. Some of them understand, but many don't. Now, if you can think of a workable way which doesn't involve a major outlay on my part, in advance of the fact, and doesn't involve many hours of packing and hauling time, mine, I mean, since I have to pack and haul from inside the house to outside, I'm listening, so to speak. Those ALTOS boxes I bought on your behalf are still in the car, by the way, but I can't open the trunk because I was rear-ended by an illegal alien with no insurance . . . In the meantime, I'm going through the just-now-moved stuff to ensure I don't expose otherwise sensitive and potentially fragile hardware to unfavorable conditions. What this amounts to is looking through the stuff I've had help to haul from the basement in the last day or two, in the dark, and examine it in the daylight, to ensure it retains some of its remaining worth, if I can do anything to that end. Keep in mind that I'm stressed to the MAX right now, because I have a new 30-hour-a-day, 8-day-per-week job for anew client, in addition to all this other headache. What's more, I'd like to avoid the exchange of dollars for anything other than expenses because of the accounting headaches that creates. I had this stuff in two sections of the basement because some of was known to be of some value and therefore worth preserving. That's of less concern to me now than it once was, but it is of some importance to me to avoid discarding the stuff in a way that will result in no benefit to anyone. I'm willing to ship, via USPS because I visit my P.O. box several times a week, those items I can easily ship. I have physical limitations which render me unable to lift items with much weight or raise my arms much above the level of my shoulders. I don't have a lot of boxes in which to ship things, nor do I have the time or the desire to shop for boxes and packaging materials. I would, of course, consider bagging a board or documentation, and taking it to Mailboxes, etc, to have them package and ship it at the expense of the recipient. However, I don't have lots of cash to invest in speculation on COD shipments. I can do this a little, but I have a boy at Harvard and one (who didn't want to go to MIT because his brother was already in Boston) at Georgia Tech. You know that's not free! The reason I decided to get into the pile of miscellaneous hardware and move it out is because I'm in the "proof of concept" stage with my new client and while packaging doesn't matter at this point, I do have to have hardware on which to implement the concepts and I no longer go out and buy, randomly, hardware which suits the task, first because it often doesn't and secondly because it ultimately winds up in "the pile." I doubt that you intended to publish this communique' but I'm also publishing my reply so I won't have to explain to every individual why I don't have inventory listings of all the stuff in "the pile" or in "the heap." This stuff is the product of over twenty five years' accumulation of hardware I bought at market price and which has not found another home . . . yet. I remember what some of this stuff cost, so I'm reluctant simply to toss it where it will produce no further value. Those old Apple-]['s still do, faithfully, the job they could do back in the '70's, though no better, and the CP/M boxes will still turn out the payroll, though not in color and without the fancy noises. I try to pass this stuff on to people who will get some benefit since it's worthless lying around unused. Clearly, you're in the business of distributing such items as we discussed before. I have no problem with that. I just can't afford to expend my limited resources making the business of getting these items moved to your venue convenient for you. Things were different two to three weeks ago, when I didn't have the trunk of my car sealed by the damage, and when I didn't have the problem of making room for additional residents in my house. As I've said before, I don't mind giving stuff away to someone who will use it. If I "get" something for it, I prefer it not take the form of cash, because of the tax-related bookkeeping hassles. As I pick my way through "the pile" looking for resources I can use for my present task, I'll make a list of what I see. In some cases, I'll know I have other parts, or documents, or whatever, which might "go with" these and probably won't have time to find them. I will however offer a partial list as time allows and as I go back inside to "take a load off." Does this make any sense to anyone?

Avail: 50-pin cables/rack-panel/connectors for unknown system

by ss＠allegro.com

Hi, (hoping this version makes it past the classiccmp filter :) Free to any home: (pick up in Cupertino, or pay shipping) two 5 meter (?) cables, with female 50 pin AMP connectors on both ends (three rows of holes: 17, 16, 17). The cables have tags reading: 422-0018-018 REV C RMH one 19" panel (about 1.5" high) with two male 60 pin connectors (matching the ones on the cables). These two connectors are wired to two long ribbon cables (3 meters?) that both end in 50 pin card connectors of some kind. The male connectors on the panel are labelled J1A and J1B. These were bundled into a surplus purchase, and have absolutely no connection with the computer I got! thanks, Stan Sieler sieler(a)allegro.com

attention MITS fiends . . .(NOW PACKING AND SHIPPING)

by jlwest＠tseinc.com

>Packing and shipping though is a straight forward problem, which I would >love to see a discussion of. > >Heavy old junk. >The only thing I see practical here is the personal transport option, stick >it in the trunk, back of the pickup, etc. I am curious about the creation >of some sort of hardware hitch hiker pool, so people going from one place >to another anyway, might consider hauling some junk for others besides >there own junk. With regards to shipping, here's my "magic" solution (like there is one) ;) Find an associate (friend, spouse, customer, etc.) who works somewhere that does a lot of shipping. These companies get HUGE discounts off shipping costs from folks like roadway, ups, etc. Then see if you can have them do the shipping in to their warehouse, and you pick it up from there. You of course offer to pay their shipping cost outright (still a huge savings for you off normal pricing) or you can setup a barter arrangement with the company (like helping with their PC network). Case in point - I'm having a pallet with a HP21MX rack, including 15231 power supply (heavy), cpu (somewhat heavy), and 7900A disk drive (VERY heavy) sent to St. Louis from California. Normal roadway shipping cost is around $695.00. However, a customer of mine does a lot of shipping and their cost from roadway is $195.00. I'm doing side consulting work for them to pay off their cost, but in a barter arrangement you could easily offer them a bit more work/time in trade than their cost for their trouble. That all being said, I've driven hundreds of miles to pick up something for my collection. But in a pinch, the above method can be better at times. I myself would be MOST interested in forming some type of hardware pickup arrangements with folks in other areas. I'll pickup stuff in my area for you - you do the same for me in your area. Then once every so often several of us could meet halfway to exchange the stuff for others and/or ourselves. Perhaps each person gets partial gas reimbursement if it's only equipment for others... who knows - I'm just throwing out ideas for all to throw stones at. FYI - I'm in St. Louis, MO - a nice central location, so I'd be happy to hold onto those 5 altairs and 8 imsai8080's for ya <grin - just kidding - I don't even collect micro's> Finally - I'm going to be in Irvine, CA (flying into LAX though) march 3,4,5, and a bit on saturday the 6th. Two questions - 1) Can anyone direct me to any favorite surplus/salvage stores in the area I can scavenge in my spare time while I'm out there? and 2) If anyone on this list is in the Irvine area, I'd be happy to buy ya a cup of coffee and exchange stories about when computers were real computers :) See ya!

21mx system I bought...

by jlwest＠tseinc.com

Ok folks - since everyone and their brother is asking.... Yes, I *DID* get a 21mx system from Berman today. However, that is not the 21mx system I was referring to in my post. I got two 21mx systems today, both from california (one from berman), but >from different places there. BTW - does anyone have HP 21mx M series cpus(2105a, 2108a, 2112a)? I'd be willing to trade 21mx E series cpu's for them. The E series I have are faster than the M's, and completely compatible (except for timing dependent program loops due to the faster speed). The software I want to run will run better on the M's - so... Let me know! Jay West

NEC APCIII - Any insights?

by roblwill＠usaor.net

Hi! My school has an old NEC APCIII. All I know about it is that it's an AMD 8086-2, and had a hard drive and floppy drive. What I want to know is if there is a way to make it boot from the floppy. I turn it on, it beeps, sits for about 2 minutes, says : DOS 2.11 command interpreter, then locks. it only beeps when a key is pressed. Any ideas on how to get into setup? -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

Amiga 1000 boot ROM & Kickstart 27.5(!)

by mark_k＠iname.com

Hi, Are there any people who have Amiga 1000s on this list? If so, please contact me, even if you can't help directly with the things mentioned below. Boot ROM -------- Inside the A1000 there is a boot ROM whose purpose is to load Kickstart from disk. In normal use -- after Kickstart is loaded -- this ROM is not visible. I want to try and get the data from the boot ROM dumped to disk; it will be interesting to disassemble this and see how it works. To do this requires using a little trick (involving the RESET instruction), which only works when Fast RAM is present. I can write a program to hopefully allow the boot ROM data to be dumped. This would need to be run on an A1000 which has Fast RAM. Please let me know if you're interested in helping with this. Kickstart 27.5 and early Amiga demos ------------------------------------ Many years ago, I received a catalogue disk from an American company called Chiron Conceptions Public Domain, who used to advertise in Amiga World magazine. Listed there were some very early Amiga demos, used for the Amiga launch in 1985. They require a pre-1.0 Kickstart, version 27.5, to work. I would really like to get hold of any of these demos and Kickstart 27.5. Below is the listing from the PD catalogue. VERSION 27.5 DEMO DISKS ======================= CC-001 --VERSION 27.5 KICKSTART Prerelease version of Amiga Kickstart. Needed for some disks. (NOTE: Will not work on the Amiga 500 or 2000). CC-002 --AMIGA SHOW STOPPER PAK Includes two of the demos shown at the Amiga debut at Lincoln Center: Eagle Demo Watch the eagle as it swoops over the digitized mountain range. Listen to it's screams as it glides across your screen! An endless loop demo. Ballet Stills A series of superb digitized graphic stills of a ballerina. (NOTE:Requires Version 27.5 Kickstart (CC-001) and thus will not run on the Amiga 500 or 2000). CC-003 --ISLAND GRAPHICS DEMO SET A two disk set of graphics pictures and animations demonstrating the Amiga. Very nicely done. (Requires external disk drive & Version 27.5 Kickstart-(CC-001) and thus will not run on the Amiga 500 or 2000). CC-004 --ELECTRONIC ARTS GRAPHICS DEMO A two disk set demonstrating Amiga's music, graphic, and voice abilities. Includes digitized voice, scenes from EA's Amiga software, music, and digitized photos.(NOTE: Requires 2 drives, 512K, and Version 27.5 KickStart (CC-001) and thus will not run on the Amiga 500 or 2000).

here's the list . . .

by edick＠idcomm.com

It has been about 20 years since I was involved with the AMI chip, but I do recall that the AMI version is a superset of the MOT version. It has features not present in the MOT part. I rather doubt they are interchangeable without firmware modifications. AMI also made a few parts for the MOT processor family which MOT themselves never got around to building. One example is the 6834, which is a two-ported RAM, I believe. It was intended for communication between multiple processors in a system, but MOT really didn't implement this until they put out the 68121, which was apparently intended as an intelligent peripheral controller for an MC68000 family processor. The '121 was a 6803 with a built-in 6834. The part's use was envisioned in a rather narrow way and, hence never saw much popularity, as it was difficult to use in any way outside this narrow scope. I'll see if I can find an old AMI databook . . .

PDP-8 Handbooks

by dpeschel＠u.washington.edu

Kevin's message propelled me to look through our library catalog for all the DEC handbooks we have. (I already sent the list to him.) That made me think of a question I've had for a while. Megan or Allison, maybe you know the answer? You two seem to have vast collections of manuals. Our library has volume 1 of a two-volume _Introduction to Programming_ set. I've always wondered what was in the other volume. (It covers details of the languages supported on the PDP-8.) But I've never seen the two-volume set anywhere else, just a one-volume book. And while I'm at it... We have the OS/8 handbook as well. I've never been clear on what the different versions of OS/8 are, so I don't know how early or late our handbook is. The OS/8 book does mention using a TD8E system, which requires either 12K of RAM or a special ROM page. Unfortunately, the Intro to Programming handbook doesn't explain how the ROM is installed. The programming handbook is specific to the 8/E, but it omits a lot of details about customizing your 8/E. I do understand that the TD8E was a total corner-cutting move -- it shifted the burden of getting the bits off the tape from the hardware to the software, right? -- and is universally regarded as a disgrace. -- Derek

I am trying to compile a pictoral history of DEC handbooks. The tentative title is a Handbook of DEC Handbooks. Trying to find a definitive list of all such publications is proving to be very difficult. The Compaq-version of DEC is still very much unorganized. The Smithsonian is doing their best, as is Charles Babbage Institute, and TCM is next on the contact list, but please consider helping. I believe the list can only be compiled through grass-roots channels. If you have any DEC handbooks, please send an email directly to me with the titles and dates of publication. Please only send a message if you have the title, not just if you sort'a know it might exist. I'll publish the list on my web site. Thank you all. ---------------------------------------------------------------------------- ------------------------------- Kevin Stumpf * Unusual systems * www.unusual.on.ca +1.519.744.2900 * EST/EDT GMT - 5 Collector - Commercial Mainframes & Minicomputers from the 50s, 60s, & 70s and control panels and consoles.

PDP-8 Handbooks

by mbg＠world.std.com

>Our library has volume 1 of a two-volume _Introduction to Programming_ >set. I've always wondered what was in the other volume. (It covers >details of the languages supported on the PDP-8.)

I'm afraid I can't speak to that... when I first used a pdp-8, it was with 4k and an ASR33 -- it took too long to load editor, then assembler, then linker by low speed paper tape, so we learned really quickly how to hand-code and toggle the programs in through the front panel.

That is simply not true. At low frequency (50-60HZ) and DC, the human body is a simple resistive circuit and will obey OHMS law E=I*R. It is impossible to have one without the other! IIRC a current of approx 100MA through the trunk of the body is enough to stop the heart. If you measure the resistance of your body and plug those factors in the foumula, you'll get an idea of how much voltage it takes to kill you. The internal body parts actually have a fairly low electrical resistance. This is because your body is filled with fluids that are somewhat conductive. Most of the bodys resistance is due to the insulating properties of your skin. Dry skin is a relatively poor conductor of electricity but, when it is dampened the resistance becomes much lower. That is why medical probes have a conductive jelly on them. The electrolyte in the jelly breaks down the resistance of the skin and provides a better path for current into the body. A cars battery is capable of producing 100s of amperes of current however, it won't fry you. When you touch the poles of the battery, the amount of current (determined by the formula above), is very low and generally cannot be felt. However, if your hands are damp, you could get a minor electrical shock from it. NOTE: A shock from DC is a burning sensation rather than the "vibrating" sensation of 60HZ curent. There are a couple of ways to getting shocked when working on appliances. Some more dangerous than others. If you are working on a device and not well insulated from the ground, there is a current path from your hand through your trunk (and heart) directly to the ground. If you are foolish enough to stand in water while doing this, the resistance through the soles of your feet is much lower and the potential of a fatal shock is greater. Thick rubber soled shoes like tennis shoes and isolation transformers are the best protection here. If you are working with both hands, it is very possible to get zapped from hand to hand. Once again the current path is directly through the trunk (heart) of the body and is quite dangerous. That is why many electricians work with in hand in their pocket. A shock that is isolated to one hand could be painful but, isn't nearly as dangerous. The worst shock that I have received was working on a antenna for a HF transmitter. I was dumb enough to leave the equipment running while adjusting the antenna and someone keyed the transmitter from a remote location. A high frequency shock (like DC) is a burning sensation and I had the blisters to prove it. Steve Robertson - <steverob(a)hotoffice.com>

Vax! (and epilogue on teledisk)

by jim＠calico.litterbox.com

Whee! it's finally here! I got my vaxstation 3100 from Tim in the mail today! It's a Vaxstation 3100 model 42 a-bd with a mighty 8 megs of ram. It works, too! Tim thoughtfully loaded VMS 6.01 on the rz23 it came with, and after hooking it up to my apple2GS with spectrum (also a classic computer :) I got the thing to boot up into VMS. VERY cool. :) Wishing it had TCP-IP, but heck, if it had *everything* I want on it, where would the challenge be? :) By the by, after attempting to negotiate with Sydex about a single user license for Teledisk pro (the 150 dollar license they sell is a 25 user site license) and failing, I've resolved not to do business with them again and have removed Teledisk 2.16 (which turned out to be a hacked version) >from my system as well as 22disk, which is their utility for copying to and >from CPM disks.

I'm fairly sure it was the box for their old TRS-80 Model >III, but it is possible it belonged to their Zenith TV they'd just bought. > >Maybe it was just a bozo-warning. Yes it probably was a bozo-warning (I like that expression. Gotta remember it. :) I've handled CRTs since I was 11 or 12 (33-34 yrs ago). There were those that were dead and had to be disposed of from a set I was repairing. When throwing them into the town dump (that's back in the days before controlled landfills and waste management laws, etc.) I was able to observe that they would take quite a whack on the side of the large part of the envelope before they broke. BUT, when they did break, the implosion caused glass pieces to fly several meters distant. On the other hand, when just the neck got broke, there was usually a definite, brief "chufff" sound when the air rushed into the envelope and no other drastic action. Here's a story to illustrate effects of an implosion: Back when I was getting more and more into TV repairs during my 17th summer, there was a dead 19" 110 degree deflection CRT that I had to get rid of. It was setting on the ledge of the basement foundation wall. Dad was helping me sort out and haul some junk to the dump. That CRT had to go in that load. Dad figured he could simply break up that tube to save space on the load as we were using the rather small family car to haul it (a '65 Corvair). Well, as he'd never himself broke a CRT nor even seen what happens during an implosion he was unaware of the "proper" way to bust one up. He held a corrugated box under the edge of the wall where the tube was sitting, grabbed a hammer and gave the side of the envelope a firm whack. Naturally, just as I started to say "Don't hit it there!!", the deed was done. At least knew enough to hold his eyes closed. A few minutes later, after we both picked the broken glass out of our hair, we observed that the largest piece of that tube was not even the size of a fist. Mom came running downstairs and asked what in the world was going on with that loud 'bang' and glass shattering sounds. Took a while to get the place cleaned up. And you can bet that my mother was there watching us to make darn sure we _did_ clean it up well. Just understand the neck of a CRT is not so fragile to just break while twisting a yoke after its clamp is loosened. Use common sense while working around a CRT. Don't work in a tight area where you could turn around and accidentally bump the neck with your elbow. Have plenty room around the monitor while on the table or workbench. Don't drop tools onto the CRT (happened to me once --and _only_ once!). Careful of getting zapped by any unprotected parts of the yoke while under power and rotating it (you could jerk around and bump the neck). There usually is a part of the plastic yoke body with which you gould grasp while rotating. The high voltage lead going to the ultor connection on the side of the envelope handles about 15 to 18 thousand volts for a monochrome monitor. Don't get close to the lead or especially the ultor connection. Following these hints should help anybody here get through a simple yoke adjustment like this.

Commodore and the Hyperion

by ds_spenc＠alcor.concordia.ca

Hi people! Somebody brought my web page to the attention of ex-Commodore engineer George Robbins (as seen in the "Deathbed Vigil" video ;) ), and he had something interesting to say about the Hyperion: GR> Commodore actually bought rights to the Hyperion design and there were GR> a couple floating around West Chester. The design served as the basis GR> for the first 8088 based PC-clones that Commodore manufactured, though GR> they ended up in normal desktop cases. The next generation was based GR> much more directly on the IBM PC's (probably for 100% compatibility) GR> then we started making our own customer chips/asic to get the cost down GR> before switching to industry standard "chipsets" for 286-486 designs. GR> In the end it was cheaper to just buy and resell clones from HK. GR> GR> On of my tasks at Commodore before the Amiga stuff took over was to GR> make a comparison of the Hyperion design and our current PC design to GR> "prove" that we weren't using any of the Hyperion proprietary design GR> features and there was no reason we should continue paying them GR> royalties on every PC we sold. 8-) As for the Commodore Hyperion in Jim Brain's Canonical List of Commodore Computer Equipment, Mr. Robbins was only able to say that maybe Commodore Canada sold Hyperions with the Commodore label as part of the deal. He has no direct knowledge of Commodore selling Hyperions in the form that Dynalogic made them. Does anyone on this list have a Commodore-branded Hyperion? -- Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/

Lack of (amongst other things) a C compiler (Gcc is not fabulous under VMS imho) is a major headache, and the Decpaq pricing structure is not likely to encourage private ownership. Access to UCX for hobbyist users would also be a good thing, but I think the Motif problem is not going to be that easy, as it involves crosslicensing from elsewhere, which means it would cost Decpaq money to give away hobbyist licenses. That this would undoubtably be a PR victory for them may not be sufficient incentive. That's my understanding of the situation anyway.

teledisk (forward of their e-mail to me)

Sorry for the long, yucky forward, but I thought I'd save folks time negotiating with these people. I basically feel they're being petulant about how nobody registered teledisk (which I understand, I guess, but can't understand why they won't *sell* me a single user copy). Note that this is in reverse chronological order, with the most recent note first. My reply to this was "thank you for your time, I will be deleting teledisk from my system." I can't fault Ms St. Clair for being unfriendly or unhelpful, just her company for being stupid.

Data Products Portacom model PC 8110

by lemay＠cs.umn.edu

Does anyone have any information about a Data Products Portacom terminal? This is a very old printing terminal (i think it was purchased in 1973) that weights over 30 pounds and is built into a black carrying case (sort of like an attache case, er, make that more like a American Tourister...) It has a teletype like ribbon, and it prints in a strange manner. the printhead is behind the page of paper, with 8 rows of 8 characters on a hexagonal horizontal rod. Its very hard to describe, since the entire device is full of somewhat bizarre mechanical parts. I really wish I had a expensive camera that could take closeup shots of stuff like this. -Lawrence LeMay

International Data Sciences, model 1310 modem test set

by lemay＠cs.umn.edu

Does anyone have any information about the modem test set listed in the subject line? This unit is dated from 1980, and uses 3 Nixie tubes for displaying an error count, or blocks analyzed. It can go as high as 9600 baud, or as low as 75 baud, including popular rates such as 134.5 and 150... -Lawrence LeMay

It's ALIVE!

by jim＠calico.litterbox.com

Well, thanks to everyone with good suggestions, and especially thanks to Don for providing the boot disk image, I've been able to get the kaypro 4/84 to boot! It came up in conversation that there were later versions of teledisk, and after some heavy web searching I found one on a page for synthesiser users that works with my computer in a dos window, even. I guess I'll have to register it now. For reference, it's version 2.16. So now it's off to Oak for nifty apps, I guess. :) I do have another question: the image on my kaypro's screen is somewhat cockeyed. Is there an easy fix for this? -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

It's S-100, 68K, multiuser, running AMOS. I don't have any docs and the only software is what's already installed on its hard drive. In fact, I don't see any obvious way to get software into or out of it: there's no floppy drive. But there is a board to backup files to a vcr (yup, a video cassette recorder).

Info on Storage Dimensions SCSI external drives needed

by rhblake＠bigfoot.com

I just obtained (and I shouldn't have) a nice unit. It is an externla case made for 2 external drives, ith 2 full height 760mb SCSI hard drives enclosed. Of course I've already been inside of it - what would everyoe think of me if I hadn't been? Anyway, it's a Storage Solutions (of San Jose, CA) model LAN2-1300S2PX and I was wondering if anyone else has one, dealt with one, or has actual tech/users manuals they might be nice enough to photocopy. No. I haven't tried to contact this company yet but I will later today. Thanks for any help in advance.

Erm, sounds like that AMI chip is a clone of Motorola's 6847 VDG, which was used in Tandy's CoCo 1 & 2, and the MC-10.

FWD: Anyone interested in tons of various PDP-11/780 and 785 boards

by cfandt＠netsync.net

Hey big and little iron fans: Found this in the ng comp.os.vms under title "Anyone interested in tons of various PDP-11/780 and 785 boards". Looks like the scrapper mentioned has some interesting stuff in addition to DEC which he may sell just for scrap price if the price is right. A few of you are from down in VA area I believe. Comments? Was posted to several other ng's too.

SoCal TRW Swapmeet

by jpl15＠netcom.com

My... where *does* the time go? Why, just last month, it seems, I was posting a similar message to this List: Saturdak, 27 Februark (dates adjusted to comply with Y-to-K conversion) 1999 is yats... Yet Another TRW Swapmeet. Any classiccmpers or others who will be in the Southern California area on Saturdak the 27th are invited to drop by and try to get some of the goodies before Marvin and myself scoop them all up. In Los Angeles, from the 405 (San Diego) freeway, take the Rosecrans exit west, go one mile to Aviation, turn left (south) under the Metroline bridge, go south about 1/2 mile... the Event will be on the west side of Aviation in the southernmost parking lots of the TRW El Segundo facility. Time is from 07:30 to 11:30 local, 15:30 to 19:30Z. I (and Marvin) will occupy spaces J21 and J23, and I will offer good company and pretty good food to any who wish to join us for an after-swap Classiccmp get-together. Last time there were eight of us... the more the merrier. If you have a few items to exchange for other items, or to sell to get money to *buy* more items... you are welcome to bring them by and display them to the Wandering Crowds. Let me know in advance if you plan on this, so Logistics may be considered.... and so I can get one up on Marvin in case you have something we both want. ;} And now back to your Regular List Programming.

question about viruses

by hhacker＠gte.net

Friends: First, let me apologise for the anti-spam message I sent to this group. I did not properly check the destination address before sending, and it was inadvertent. Second, about computer viruses. Sam Ismail said that he had an article from the LA Times dated in 1986. I would love to see the article. Ward D. Griffiths III noted the value of the idea as described in the book by John Brunner, The Shockwave Rider. It is an excellent book but, the worm (or virus) issue is ancillary to the plot of the book. Still, in my paper, Apple Worm (published in the November 1986 issue of Call A.P.P.L.E. magazine - as the cover story), I make reference to the book. In this paper, Apple Worm, I provide a detailed design of a virus program which would operate upon Apple II computers, via the Hello program mechanism. As far as I know, it is the first such exposition of the techniques of computer virus writing ever published, though I am aware of some descriptions of the idea as far back as 1972. This earliest description is published in the journal Software: Practice and Experience. There is another early publication of this nature in the journal Communications of the ACM, written by Schoch, et al. I do not remember the date of the article but, I do have a copy. I will do the necessary research and report the information, if no other person bets me to the punch. It is very likely that my paper, Apple Worm (written together with the late James R. Hauser, a former professor of mine at the California Polytechnic State University, San Luis Obispo), is a major influence upon the proliferation of computer viruses at that time. :) As far as I know, the Brunner text is the first mention of the concept of a computer virus in the literature, as the paper in Software: Practice and Experience mention only the game DARWIN, as played at the AT&T Bell Labs. Interestingly, DARWIN is the source of motivation for A. K. Dewdney's construction of the game Core War. William R. Buckley -----Original Message----- From: Ward D.

My Lucky Day!

by rigdonj＠intellistar.net

Today I just visited with an old friend that I haven't seen in years and found out the he's an OLD computer buff. Turns out that he has a house full of OLD computers. SWTPC, Altair, Alpha Micro, Lisa and more. Today I picked up a MITs 8" disk drive for the Altair and an Alpha Micro computer. He's promised me more including another Altair computer and "nearly one of everything WSWTPC sold". Does anyone have docs for the Altair 8" drive? I need to find out if everything is here and how to hook it up. Does anyone have any good URLs for the Alpha Micro stuff? I don't know what all these cards and stuff are. There's some very strange looking stuff in it. Does anyone have any pointers for fixing the power supply in an Apple Lisa? Joe

Cromemco Dazzler

by edick＠idcomm.com

I was digging throught the pile of "stuff" from days of old, and find I have a board-set (S-100) which is a Cromemco (remember them?) Dazzler video board set. I don't remember using this for anything. What probably happened is that I read the doc's and determined it was indadequate for my purpose and set it aside . . . the box (the cardboard box in which it was pacakged by Cromemco, looks like sh*t but the contents were apparently unharmed by the passage of 20 years, of which most were spent in the junk pile. Is anyone interested? Dick

Installation and Service 29425a cabinet HP3000 series II system service manual HP3000 series II system installation manual HP3000 series II system microprogram listing HP3000 series II microprogramming language description Maintenance manual 30032B asynchronous terminal controller for HP 3000 Maintenance manual 30115a 9 track NRZI-PE mag tape subsystem for HP3000 CE service handbook for 7911/12/14, CS/80, 7941/45, 9145A CE service handbook for 300H, 300S, 9144A, 9145A, 35401A, diagnostics Operators manual 7961b, 7962b, 7963b Plus manuals for the following terminals: Microterm Act I, Act IV, Act V, Mime2, Mime340, Ergo2000 Televideo 910 Beehive minibee 4 Hazeltine 1500 Here's the disclaimer - I haven't dug into these manuals in detail, but on the surface they seem to not apply to my interest areas. If there's one you want, let me know. If after looking at it more closely I find it is applicable to 2000/21mx hardware that I have or plan to acquire shortly, I'll only provide copies not originals. BTW - still looking for a 2748A/B type paper tape reader, and always 7900a disc drives! Jay West

VT320 terminal

by lwalker＠mail.interlog.com

In a thrift-shop I picked up a copy of of a DEC Installing and Using the VT320 terminal. Later I ran across the machine itself with K-B at the main store. I passed it by at the time since I had acquired a bunch of other equipment and couldn't handle it. It was only $15 , but I'm rapidly running out of space. Is it worthwhile going back for it ? Or is it fairly common and easily available ? ciao larry lwalker(a)interlog.com

teledisk2.12

by edick＠idcomm.com

Didn't the Kaypro use 1K sectors? ...and why do I have the impression that the Kaypro had a WD 1770 or 1772 (28-pin) FDC on it? I used to swap disks with the AMPRO which was like this all the time.

Test and Maintenance tools for vintage computers

by go＠ao.com

My interest in vintage hardware certainly includes acquiring and restoring the hardware itself, getting copies (or originals if possible) of the manuals and other documentation, but also includes acquiring the original "tools" and other articles used to keep these old systems running. For example, I have several teletypes of various models, and Teletype corp was fond of having all sorts of special tools used to keep these things running smoothly. Items included special screwdrivers, burnishing tools for cleaning contacts and even a custom "tuning fork" for aligning the speed of the governored motor. I recall, for example, that our DEC field service engineer at Oregon State had a special "tuned hammer" for "thwacking" the circuit boards in our PDP-8 (straight-8) that ran our front-end terminal multiplexor. Basically it was a modified "center punch" with a special paddle in place of the sharp-pointy thing. You dialed in the amount of "thump" desired (in special DEC-calibrated units: (1-light to 9-break-the-edge-fingers) and pressed the tool against the card handle, pushing until the center-punch device clicked. All boards were supposed to take at least a "4" if I recall (any DEC FE's out there?) and any that didn't were replaced. So, what's the strangest "field service" tool out there? And what success have you all had in finding these things? For my teletypes, it's been a difficult task to find the pieces I have and I only have a few of the 30-some "official" tools TTY-corp produced for the model 14, 19 and 28 families. Seem to be a lot scarcer than the documents. Gary

Wanted: TeleVideo CP/M machine(s)

I've got a TS-802H, in storage with my PDP-11's etc. I'm planning to unearth all this old stuff now that I have a place with a basement. I've got a lot of files on the TS' hard disk, which I'd want to look through before even thinking of selling it. I'm not sure how much time I can devote to restoring my ancient toys, but it worked last time I booted it a few years ago. Internal HD and 4.5-inch diskette drive to the left of the monitor screen. I have the User and Maintenance Manuals, with complete schematics, which may be useful to you. It has some pretty fancy high-speed serial port capability, used for the networked systems. -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + Robert Lund | Out here on the perimeter there are no stars + + lundo(a)interport.net | Out here we is stoned - Immaculate + ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

VT320 terminal

by dburrows＠netpath.net

I have several here and they sell commercially VERY slowly. I have sold them in large quantity without keyboards for cheaper than that. If you ever need some let me know. I work with a couple of recyclers that love to have me take some off their hands for resale. They don't have to tear them down for certified disposal then. Dan In a thrift-shop I picked up a copy of of a DEC Installing and Using the VT320 terminal. Later I ran across the machine itself with K-B at the main store. I passed it by at the time since I had acquired a bunch of other equipment and couldn't handle it. It was only $15 , but I'm rapidly running out of space. Is it worthwhile going back for it ? Or is it fairly common and easily available ? ciao larry lwalker(a)interlog.com

ESDI Drives and controllers

by rhblake＠bigfoot.com

Have a bunch of working 5.25" full and half height drives, ESDI type, in working order to sell. Many of them are half height Seagate 89 mb and I have a few Maxtor 170 mb full height. Can be sold with or without contoller, which are mostly Seagate. Cables will be included with the full setups. These are AT controllers and will work in any machine with 16 bit ISA slots. You only need to set your CMOS to drive type 1 and the rest is done by the controller and drive. 89mb drive $8.50 plus ship 170 mb drive $12 plus ship Add $6 to either for controller and cables For those that want 2 drives and controller I'll go the price of 2 drives and include the controller free, with cables for 2 drives. Email me direct (not on the list) if interested. I really don't want to move this stuff come summer. Shipping will be by USPS parcel post from 40144 to you, insurance optional. USA and APO/FPO only.
