Should I add a "Micro" PDP11/73 to the Herd?

PDP-16 (register transfer modules)

by Anthony.Eros＠compaq.com

Does anyone have a PDP-16 (sort of a prototyping machine using register transfer modules) that they'd be willing to part with? I thought I'd made arrangements to snag one from "JohnB", but he appears to have disappeared from the face of the earth. This machine looks intriguing and I'd really like to find one. -- Tony

I think I said exactly that. The YOU is the holder of the finished product not a LICENSED producer who by expressed permission (contract) can and does produce copies for profit. However My reference also goes to intended use. For example a Encylopedias, they are an information source as reference where wholesale copying is bad but, the contained compendium of knowledge is NOT the property but, the format and package is. >> Software is going the >>route of, you pay for the media, manuals and support(optional) and also >>for rights to use under specified conditions as a CONTRACT.

(The >e-book guys can identify change of ownership and guess what, you can't give >your ebook to another person without them having to rebuy the book!) You sure? there are such things as licensed copies, copies under NDA and restricted printings. the assumption is you do not retain a copy in both cases. There is the distinct difference. If I give a paper book(tape or other media) away I no longer retain a copy, electronic means allow me to give a COPY and keep the "original" that is a clear copyright violation. There is also the case of I have a music CD, I copy it (or parts) to tape for use in my car where CDs are not useful. This would be format translation and is usually allowed. >Just because you have a copy of "Catcher in the Rye" it only gives you the >right to read it, not aloud at some gathering, or to put it on as a school >play.

Also no person from the record company or author is allowed to take it from you. They can audit you to see if it's for profit (ASCAP!). DJs for instance! >author. For some really interesting insight into just how intellectual >property works, check out the Napster and MP3 cases that have a lot of >their material posted on various web sites. Can of worms. At the core is who "owns the original work", what that original work is and who is allowed to profit from distribution. The best case of this is I make a recording my arrangement of Bach using pots and PC and sell it on CD. Who owns what? For software, it's worse. I write a version of Basic for 8080, assemble it using MS-MAC, using a Z80 box, under cpm and sell it on a sony microfloppy. Does Darthmoth College get something for the basis of the language? Howabout MS for the use of the MAC asembler used to get a binary? does Sony share as it's their media? Howabout Zilog as it was their cpu design even though it was a Mostek chip? Oh and Intel for their cpu and nemonics? Oh and the company that owned the Z80 box for accounting? What is created?, Who did it, who has a legit share? In any case the license (contract) for RT-11 is specific and any misuse outside that permitted use is a violation subject to legal remedy. Allison

Should I add a "Micro" PDP11/73 to the Herd?

by dhquebbeman＠theestopinalgroup.com

Good Morning, Fellow Classicians... A MicroPDP 11/73 (that's how it's listed) is available on E-Bay, it's not selling, so I can probably get it for the starting bid of five bucks, and it's local. I have no backround with the PDP-11 (and thus my recent query regarding those cards I have). It comes with a TS05 tape drive, which from the photo appears to be a Cipher F880 Microstreamer. I'm thinking of getting it just to have a spare for the Prime's tape drive. Here is what the seller has to say about it: : This is a Digital Equipment Corp Micro PDP11/73 computer : with a TS05 tape drive mounted in a rack. Also included is : what I think is a hard disk unit mounted below the computer. : The front panel of this unit says 'USDC CSS-800 Compact : Storage System'. Also included is a VT320 amber video : terminal. If you look at the photos below you will see that : there is a large space in the middle where something is : missing. I think that there were 2 hard disks mounted in this : space, but they were gone when I got the equipment. I bought : this stuff from the University of Louisville Medical School. : This is one part of a larger system. I have powered the : PDP11/73 up and it seems to boot up OK. When booted, this : is what come up on the screen: Testing in progress - Please : wait 1 2 3 4 5 6 7 8 9 Starting ROM boot 173356 @ I think : the '@' is a command prompt, but I don't know what to do : from there. The CSS-800 unit has lights that come on in the : front, and so does the tape drive, but I have no way to test : them. I can't be sure if this equipment is working properly, so : it is sold AS-IS. : : Should I rescue this machine? What OS do I need to acquire for it? Thanks for all replys, -doug quebbeman

Cheap parts available for AT&T 6300, AT&T 6300 monitor

by whdawson＠mlynk.com

Wakeup call! Haven't had any wanting the whole system or the monitor. It's parts time! Does anyone need any spares for their AT&T 6300? First the pictures, then the story: http://www.wpic.com/whdawson/classiccmp/ATT6300front.jpg http://www.wpic.com/whdawson/classiccmp/ATT6300rear.jpg I stopped in the local Hidden Treasures (actual name) store a couple of weeks ago and noticed this on the shelf, minus keyboard. I've been a regular visitor there for the last several years, and when I pointed out to Terry, the new manager, that this system was kinda useless without the AT&T keyboard, he told me to just take it, as in free, because it was probably going to end up in the dumpster anyway since no one seemed interested in it and this would save him the effort. The power supply fan runs, and little else. No cursor, no boot, no drive activity other than it initializing, no nothing, although the AT&T monitor appears OK since when I turn off the system I get green all over and retrace lines as the power collapses. Same if I unplug the monitor when the system is powered up. The monitor is powered from the 6300 and has a jumper from the PS to the video board, standard 6300. Here's the parts available: AT&T monitor, no screen burn, nice, cord storage in swivel base. AT&T 6300, made in Italy: PC1050 motherboard, markings of 0091-0-5-00 REV P4, AT&T 227692 T 10 CPU3 9/84, BIOS REV 1.21, FCC DVR7NICPU3; 8086-2 CPU, memory chips are MOSTEK MK4564-N-15; OLIVETTI Video PCB, full length, markings of CRT 313M; OLIVETTI Bus converter; 5.25" floppy drive; power supply; etc. This system is in very good to excellent condition. The computer is dusty inside, but even the felt feet are still on it. The CRT case is not yellowed. The story I got was that an elderly lady had donated it to the store. Cost is only 1.2 x shipping (cheapest way, unless specified otherwise)for whatever assemblies you want from it. Please email me off list and let me know what you need. FCFS I'm offering this to the list because I have enough going on and enough systems to restore to keep me busy for the next 10 years. Yes, I can probably find a keyboard and can also likely fix it, but I don't see anything wrong with some systems ending up as parts donors for others. I'll post to the list on the status of this as necessary. For shipping purposes, my zip is 15301. Bill Dawson whdawson(a)mlynk.com <mailto:whdawson@mlynk.com> ?

Modern extended-play tapes use a thinner nylon tape (to fit more tape in the standard cassette), which is more prone to stretching and breaking with repeated rewind/play cycles. Some older answering machines used very short standard cassettes, I'd estimate about C10 length. If you can find a store that still sells those (even a liquidator selling off those awful novelty "celebrity answering machine messages") they might be suitable. They would also be newer than the 15+ year old computer cassette tapes. Another option would be to shop for a cheap disk drive for your system. In my experience old 5.25" floppies in good condition are much easier to find than cassettes. Regards, Mark.

Even though the reply had a funny touch to it how else do you expect to have your collection survive you? Or don't you care about it? The main point was that there will allways (I hope) be other collectors willing to take on some else's collection there can even be a public distribution/sale or other for people interested. The thing I'm worried about is about my stuff ending in the trash (160 or so machines with peripherals and documentation) and I've specifically told my wife that if I die she should post a note on this very list and ask for help in disposing of it. She does consider my collection as a pile of junk but she also knows that this is not the opinion of everyone. Actually I am thinking of adding something to that nature in my will. I allways tink that I have time to think about it (I'm 34) but you never know... If you worry and value the conservation of your machines you should take the same dispositions and make sure that none is lost.

I have owned a computer continuously since 1976, when I built a SOL (and I helped finish building an IMSAI the next year that was botched by a physics professor). Of the dozen or so computers I own, two are Windows boxen. My physician told me to stop reading the licences, or I'd have a stroke. The first computer I used was a CDC6500 running DualMACE at Purdue in 1974. I checked- Purdue OWNED the computer, they did not RENT it. >From there I went to a CDC6600 running Kronos 2.1 at Indiana University; I had a computer account for each of my classes, and one given me for donating my services as s student consultant.

I wrote nothing stating that I was looking for free software. How is it that you take not wanting to be ripped of to mean that I want something for free? The problem isn't that I don't understand the computer industry, it's that the computer industry has been taken over by robber barons. It happened during the 1980s; I recall it distinctly.

Free: Apollo DOMAIN/OS Software Distribution Tapes

by xds_sigma7＠hotmail.com

Actually, Domain/OS is one of Apollo's 3 operating systems... Apollo started back when AT&T wasn't licensing UNIX for commercial use, so they had to create their own UNIX clone, which was actually better than UNIX. This was called Aegis, later changed to be called Domain/OS. Later, when AT&T did start licensing UNIX, Apollo was smart enough to know that even though Aegis or Domain/OS, depending on what you called it, was better than UNIX, the AT&T standard was what mattered to people, so they licensed UNIX, and that became Domain/IX, and shortly afterward, HP bought Apollo and killed basically everything other than Prism (PA-Risc).

You just need to make sure it's set to generate plain text (not HTML, RTF, or multipart/mixed) in some reasonable character set, for new messages, AND override the use of HTML/RTF/whatnot when replying. Besides, there are plenty of other Windows mailers besides Outlook; it's not a reason to go off the deep end. > However, you need to remember that not everyone here uses that Microsoft > rubbish, so you shouldn't be sending e-mail that requires the recipient > to do anything other than read it. True, in fact the Merrill Lynch survey I saw on CNN a little earlier today showed that less than three-quarters of people using Windows use Microsoft email software. Since only about 2/3 of PCs (in the loosest sense) run Windows, that means only about half use Outlook etc. -- Pete Peter Turnbull Dept. of Computer Science University of York

But you ought to realise that ISO-8859-x is not ASCII; the lower 128 characters are the same but the remaining 128 (top bit set) are foreign-language characters and additional symbols -- ASCII is a 7-bit character code while the ISO 8859 ones are all 8-bit. -- Pete Peter Turnbull Dept. of Computer Science University of York

Together, democracy and free enterprise constituted a severe paradigm shift for the robber barons, but eventually, they figured it out. So, if they're going to stand behind every tree on the highway, ready to exact from us a toll for any thing we want to do, then we have to figure out how to travel without using that highway, rendering their strong-arm tactics moot. -doug q

Legal Question

by mrdos＠swbell.net

All this talk about RT-11, RSX-11M,RSTS/E licensing details is making me wonder. If I acquired a PDP-11 of some kind, and it came with RSX-11M and/or RT-11 and or/ RSTS/E, would I have to have a license? I know a license is legally required, but is it essential in running the OS? Does the OS have any way of checking for one? What is required for running the OS? I really don't know anything about the PDP-11 family. Thanks, Owen

Ah, I stand corrected... and that would explain why the system was always flaky with that board in, and stable without it (I was blaming the bus). So, knowing nothing about the half-life of the welding material, can you tell me, has the material in the welds decayed enough now that the board should operate in a more stable fashion? -dq

A little more Am2900 learning/evaluation kit info

Wasn't Prime also Pick based > systems? Prime sold a subsystem called Information which was more-or-less a clone of Pick, and from the mid-80s on, this may have been its best-selling product (I'm certain it was in the UK). But prior and subsequent to that, Primes were very prevalent as university timesharing systems, and laboratory support systems. The Primos operating system had its initial roots in an older OS they called DOS, which had some legacy from another Prime OS, RTOS, which in turn was a port or re-implementation of Olert/4 and/or SAMTRAN, a Honeywell Controls OS funded by NASA. Beginning with the P400 processor, Prime systems were 16-bit data/32-bit address versions of the Honeywell Multics architecture (which was 18-bit data/36-bit address). -doug q

DECassetes and HPIL/HPIB available

by schoedel＠kw.igs.net

NOTE: I am currently busy and will probably not reply promptly to email. To those already waiting for replies on other things, my apologies; I'll respond as soon as I get spare time. I have 200 DECassettes (TU-60 tapes) on hand; I want to keep a few in case I ever get a TU-60, but would like the others to find good homes. They are 'new' in sealed bags (though as they are obviously old magnetic media and I don't know how they have been stored, this is no guarantee they will be usable). Ideally I would like to trade the lot for something else interesting. The things I'm looking for that a TU-60 owner would be most likely to have available are an RL11 and RL02 packs, but if you want the tapes and have anything else to go, consider making an offer. Failing that, the tapes will be available for sale, to TU-60 users only, at some price not far above shipping cost. I also have a number of (used) HP-IL to HP-IB interfaces (HP 82169A) available. -- Kevin Schoedel <schoedel(a)kw.igs.net>

Free: Apollo DOMAIN/OS Software Distribution Tapes

by cube1＠home.com

Please read ALL of this message CAREFULLY before responding. Incomplete/erroneous replies will be directed to /dev/null, with or without a reply based on how busy I am and how I feel that day. 8-) Requests for further information may not be responded to quickly. I have obtained, due to Y2k related activities and general cleanup, a VERY LIMITED number of copies of original software distribution tapes for the Apollo Domain/OS operating system and some product support kits. (I also have some other software, but due to licensing, I am not comfortable making that available. However, if you have NFS, Omniback, CC or DPCE software for Apollo Domain/OS and are having problems reading your tape(s), if you scan in a copy of your label and send it to me, we can see if we can arrange something). I am making them available at no cost, except that the REQUESTER PAYS THE PACKAGING AND SHIPPING COSTS (usually just a pound or two). The prepayment will be based on the estimate from the UPS web site. If you send me too much, I will send the difference by other means after I ship, if it is more than $2.00 -- otherwise I will not bother). I am making them available to people who (priority order) (USE THIS CODE BELOW) PRIORITY CODE: 1. Has an HP/Apollo Domain machine (proof required, including node-id, preference would be a picture), but does not have tapes (you are on the honor system for that part) 2. Is writing a simulator and needs software (some proof required, such as design documentation, compiler headers, ...) (Having been in that boat myself, I have empathy for anyone in that situation. But, I'd be surprised to find anyone in this situation for an Apollo Domain/OS machine). 3. An education institution (this would really surprise me, but you never know) 4. Has an HP/Apollo Domain machine (proof required -- see above), has tapes, but would like a backup set.2 Shipping code (see below) PICKUP: If you can pick the tapes up. Gets you 1 notch higher priority. SHIP: If you need to have them shipped to you. (You pre-pay shipping). Available only to folks in the US and places UPS will ship to with no headache for me (again, these are free, after all). Again, the requester must PREPAY SHIPPING based on an estimate from the UPS web site. The tapes are little used, and in their original plastic boxes with their original labels. The tapes date from around 1990 - 1992. ( I read thru a set of tapes like these to do a software install last year without a problem, but I can make NO GUARANTEE that the tapes are readable. (after all, they are free). Requests for tapes should be sent via email. PLEASE READ *ALL* of the following information to the end of this message CAREFULLY. Request MUST include the following filled out (please cut and paste into your message) Request MUST include "DOMAIN/OS TAPE REQUEST" in the subject of the e-mail, and should be addressed to: c u b e 1 (at) h o m e (dot) c o m ************************ NAME: Your Name ADDRESS: Your Street Address / City / State / Zip / Country routing code EMAIL: Your e-mail address SET: The Tape set number(s) you would like.

I need to allow some time for priorities to be properly registered. I will ship when I am good and ready, probably in July or August. (After all, these are free -- but I do want to get them out of my hair). Generally YOU MAY ONLY REQUEST 1 SET. Exception: If you request one of set 10, 11 or 12 you may also pick one of set 13,14 and/or one of set 15,16 Note: If you have a 68040 based machine, SR10.2 is useless.

Thrift Store find: Apple IIgs

by ethan_dicks＠yahoo.com

I have a variety of Apple II machines (I used to make my living on them long, long ago) and my little brother, an avid thrifter, found a IIgs for me this week. ISTR there are multiple varieties; this one appears to be fairly old. It has a memory card inside with 256K of RAM soldered down, and spaces for another .75Mb. The ROM is version 1.0. Just playing around, I figured out how to get into the config menu and set background colors, 80 column, etc. I happened to have an external 5.25" Laser drive I got with my $15 IIc+ and was able to boot up the only DOS 3.3 disk I could find - Zork I. So... now that I have two machines that want to have 3.5" drives and no copies of DOS 3.3 on that medium, is it possible to aquire it anywhere? I have Macs, etc., so I can make a 3.5" disk from an Apple disk image if that's what it takes. Also, are there any ways I can expand this puppy? I happen to have a couple of old Apple double disk drives (the kind that came with the IIe); does anyone know of a diagram to make an adapter for the 19-pin connector that the newer computers take? Thanks, -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

New Finds

by jrkeys＠concentric.net

Well the week back from vacation has been pretty good I hit 3 auction and came away with a few good deals. 1. HP 6300 series 650/A 2. HP 9000/300 3. HP 9144 4. HP 6000/670H - 4 of them mounted in a nice rack. 5. TI99 color monitor the size of a TV and looks just like an old 19" model. 6. AMD AM 2900 Evaluation & Learning kit. A nice single board computer with the box but no manuals. There was a sheet titled "Am2900 Kit Programming Work Sheet". Anyone have more info on this unit ? 7. 2 - Toshiba T5200/100's that both work great. 8. Zenith SuperSport 286 with carrying case, will not boot up. 9. Grid GridCase3 not working 10. An old Informer in a nice case. Not tested yet. 11. Compaq portable III in carrying case, not tested yet. 12. digital LA50-RA printer. 13. digital VT240 model VS240-B 14. Tandy 4000 PC There were several van loads of items that are not yet 10 years old but I added them to my collection from the first two auctions. At a City/school auction today I won the bid on over 80 computers, ext floppy drives (Apple all types), ext. hard drives for Mac's, many keyboards, monitors, and many other computer items all for $1. Sorry to say I had to leave a large amount of this stuff, there were all types of early Mac's and PC's. My poor van was overloaded with computers this evening and I got home at 9:30pm in the dark so I was not able to unload too much tonight and will have take off work for half a day to unload my Van and go back for more of the items. I hope to have a more complete list by the weekend and will post the older items. John Keys

Louisville, Kentucky, is an ideal site for any convention. We are located in the heart of United States, we have ample convention facilities (but don't choose the weekend where we have the Future Farmers, NHRA Nationals, etc). We have great entertainment facilities (food, music, horse racing), a riverboat casino within a 20-minute drive, a Deja Vu (and plenty of similar facilties), scenic riverboat cruises (these without gambling), a bridge that goes nowhere but stimulates endless debate. What we appear not to have are these places I hear about that have piles upon piles of old computer equipment. At least, if it's here, it's staying hidden from me. Just a thought... -dq

How do you finance/afford your computer collection?

by SUPRDAVE＠aol.com

I'm interested in hearing how others on this list afford to maintain and expand their collections. Especially people like John R. Keys. 8-D Basically I take money out of my budgest and buy something when it strikes me. Lately, Ive actually turned down some of the more popular computer models because I either have one or more, or space is at a premium. I also pay monthly for small off-site storage to hold some machines as I'm reaching over 150 computers+accessories now. Is it feasible to start a non-profit org to help pay for some of the costs one incurs while enjoying this hobby or how would one solicit donations? I am reluctant to become too commercial or plaster my domain with ads. hurry, hurry step right up! see the computers you used as a kid! www.nothingtodo.org

AT&T 6300 with monitor, up for grabs, almost free + shipping

by whdawson＠mlynk.com

Hello all, First the pictures, then the story: http://www.wpic.com/whdawson/classiccmp/ATT6300front.jpg http://www.wpic.com/whdawson/classiccmp/ATT6300rear.jpg I stopped in the local Hidden Treasures (actual name) store a couple of weeks ago and noticed this on the shelf, minus keyboard. I've been a regular visitor there for the last several years, and when I pointed out to Terry, the new manager, that this system was kinda useless without the AT&T keyboard, he told me to just take it, as in free, because it was probably going to end up in the dumpster anyway since no one seemed interested in it and this would save him the effort. The power supply fan runs, and little else. No cursor, no boot, no drive activity other than it initializing, no nothing, although the AT&T monitor appears OK since when I turn off the system I get green all over and retrace lines as the power collapses. Same if I unplug the monitor when the system is powered up. The monitor is powered from the 6300 and has a jumper from the PS to the video board, standard 6300. Here's what's included: AT&T monitor, no screen burn, cord storage in swivel base. AT&T 6300 with: PC1050 motherboard, markings of 0091-0-5-00 REV P4, AT&T 227692 T 10 CPU3 9/84, BIOS REV 1.21, FCC DVR7NICPU3; 8086-2 CPU, memory chips are MOSTEK MK4564-N-15; WD1002-WX1 controller; Seagate ST-225; OLIVETTI Video PCB, full length, markings of CRT 313M; OLIVETTI Bus converter; 5.25" floppy drive; power supply; etc. This system is in very good to excellent condition. The computer is dusty inside, but even the felt feet are still on it. The CRT case is not yellowed. The story I got was that an elderly lady had donated it to the store. I'd prefer to sell this system as it is, complete, for $10.00 plus shipping (2 boxes). If you are only interested in the monitor, $10.00 plus shipping also. If no one is interested in the 6300 intact, then I will part it out, 1.2 x shipping for whatever assemblies you want from it. Please email me off list and let me know what you need. Anyone who wants the whole enchilada gets first dibs. If no one does, parts seekers are on a FCFS basis. I'm offering this to the list because I have enough going on and enough systems to restore to keep me busy for the next 10 years. Yes, I can probably find a keyboard and can also likely fix it, but I don't see anything wrong with some systems ending up as parts donors for others. I'll post to the list on the status of this as necessary. For shipping purposes, my zip is 15301. Bill Dawson whdawson(a)mlynk.com <mailto:whdawson@mlynk.com> ?

So on one particular flight out of San Juan where most people (apparantly) were complaining it was too cold, it was, for me, far too hot, and I removed my shirt. Only my shirt. Boy, I'm still hearing about that one from my co-workers... 8D -dq

POST code for IBM P-70

by SUPRDAVE＠aol.com

In my situations, incompatible memory usually posts a 225 or 221, but hard to say what's happening here. The 165 comes up usually because the .adf file for an installed adaptor card is missing. That will need to be cleared before the computer will boot from the hard drive. The P70/75 had issues with the floppy drive since it's mounted vertically but hopefully wont be a problem here. try using a cleaning disk on it. goto http://members.aol.com/mcapage0 choosing the PS2 area and download peter's adaptor card ID disk. any ps2 should boot that disk. Another thing i've noticed is dont access newly created reference disks on win9x machines. Ive discovered that sometimes doing a DIR on them renders them unbootable for some reason. have fun with that P70. it's a neat machine. www.nothingtodo.org In a message dated Wed, 21 Jun 2000 4:34:31 PM Eastern Daylight Time, "Mark Gregory" <mgregory(a)vantageresearch.com> writes: << -----Original Message----- From: Joe <rigdonj(a)intellistar.net> To: classiccmp(a)classiccmp.org <classiccmp(a)classiccmp.org> Date: Wednesday, June 21, 2000 1:35 PM Subject: POST code for IBM P-70 > Can anyone tell me what the POST codes 165 and 221 mean on an IBM PS2 >P-70?

To answer the other question, we had snow in January 2000, the first in quite some time. Usually it just rains all winter. It also snowed on Christmas Day, again, the first since perhaps 1977/78.

HP 715/33 available - Austin, TX

by mrbill＠mrbill.net

(I apologize if this breaks the 10-year rule; I *think* this box is about as old as a SS1, or darn close to it - couldnt find a date of mfg..) I've got a barebones (no HD, no RAM, no kb/mouse) HP/Apollo 715/33 available in Austin, Texas. You can find specifics on it at http://parisc.workstations.org/systems.html and http://parisc.workstations.org/systems/715_scorpio.html Nice little PA-RISC box; however, I just have no use at all for any HP stuff. Will trade for anything DEC/VAX related (literally, anything - make a halfway serious offer, you might be surprised) or will even possibly give it away if someone has a good enough need/reason why I should. I just need it out of the way. I'm looking for VAXstation (3100, 4000-VLC, etc) machines and hardware, BTW.

How do you finance/afford your computer collection?

by jeff.kaneko＠juno.com

I get an allowance. All of my computer-related purchases come out of that, except if it's something for my wife's machine, in which case it comes out of our general budget (which doesn't really exist, but we pretend). I'm not aquiring many systems these days; I'm trying to concentrate on getting the systems I have now in some decent shape-- so mostly parts and docs, and junk. Since most of the systems I have are not considered 'investment grade', I can still get most of what I need pretty cheaply (MFM drives-- $1, for example). It gets expensive when I have to buy a part that's still used alot in the 'mainstream' (SCSI CD-ROM's, for example). Almost all of my machines occupy my basement-- the rest occupy a small corner of my otherwise full garage. ________________________________________________________________ YOU'RE PAYING TOO MUCH FOR THE INTERNET!

The question I posed is if anyone is writing mailers for > the older systems so they can handle HTML properly. Again, is this a blanket statement that anything that isn't an Intel box running Windows is an "older system"? As to the question...yes, many modern mailers for non-Windows systems (old systems and new systems alike) deal with HTML just fine. I think the animosity toward HTMLized email (at least for me) comes from these points: 1) It's just not necessary for effective communications. 2) It's a waste of bandwidth and system resources. 3) Technical people generally want genuine functionality to prevail over "flash"...which is why many (most) technical people in the industry (Visual Basic programmers don't count) don't have Windows boxes on their desks if they have anything to say about it. 4) It's a clear outgrowth of the overcommercialization of the Internet, in which uneducated users think the World Wide Web *IS* the Internet, thus they try to cram the World Wide Web into everything they do, and conversely, cram everything they do into the World Wide Web. -Dave McGuire

Blinking lights hidden

by rdd＠smart.net

Something's been puzzling me: when I look at my CDC SMD drive, the NCR applications processor, some smaller SMD drives, LEDs in my 11/44, etc., there's something I just don't understand. Why did companies begin hiding blinking lights, status displays, etc. behind covers, in places behind the front panel that aren't obvious at first glance, hidden in boards in a card cage, etc.? -- R.

NCR model 3401 class 5451

by rdd＠smart.net

Greetings, is anyone here familiar with an NCR model 3401, class 5451 "application processor"? On a hand-written label on the front of the machine there's a description of the memory in it: 8MB, 145ns. This box has the following switches on the front panel, in addition to the power switch: Station ID (two thumbwheels) Load options: local/aux disk/tape primary OS/alt OS BCD restart/system reset diag port: on/off mode: normal/diagnostic ps margin: +5%/normal/-5% On the back of the machine are the following connectors: LS link (low speed link?): pos 0, pos1, pos2 (9-pin) Diagostic port (25-pin - RS232 port?) System bus: channel A, channel B (9-pin) HS link (high speed linl?): pos 4, pos 5, pos6, pos7 (9-pin) One interesting thing about this system is a board labeled "writeable control store" - does anyone know it this is user microprogrammable? On this board are about 45 AMD (I think) 8648 ICs and about 27 8651 ICs, in addition to what I think may be EEPROMs (Fairchild MB7142H), as well as morotola 8644A, 8644B, 8648 and 8649 chips and a few other ICs. Attached to this board is a other board that is apparently the main part of the CPU with about 6 (from what I recall) square ICs, about 1" square, with heat-sinks that I haven't figured out how to remove yet to see the part numbers. Did anyone here purchase the machine like this that was listed on e-bay? Another apparently related NCR box that appeas to connect to the SMD drive only has the following indentification on it: "class H6830-STD1-01-46." Coming out the back are three cables: one that looks like it's got about 50 conductors in it, and two that appear to have about 20 to 25 conductors (these are just my guesses, haven't counted them). There are also two 50-pin connectors. I think this connects to the hard disk, but I can't figure out how, or if, it connects to the model 3401. Is anyone here familiar with the above equipment? -- R.

Is it safe to power it up with this board missing? Very likely. I pulled the 1000E Installation and Service Manual (HP p/n 02109-90015, dated Nov 1979) and it would appear that the board your power supply is missing is p/n 5061-1349, the battery backup board, which is only present in 1000Es with the battery backup option. To confirm this, there should be another board, 5061-1351, in another slot in the power supply -- this is a jumper board that is used in place of 5061-1348, the battery charger board, when the battery backup option is not present. I think you'll find this latter board in the slot closer to the front. Looks like the installer is expected to adjust the power supply with it installed in the computer. Test points are on the crossover assembly (A6) that is visible when you remove the top cover, and the main adjustment is the +5V ADJ potentiometer that is visible on the power supply board that is partially exposed when you lower the front cover: it's the one that is under the LOCK/OPERATE switch. Supply voltages are: supply v max cur upper lim lower lim test point +5V I/O 50A 5.25Vdc 5.00Vdc A6 +5V +5V M 4.5A 5.25Vdc 5.00Vdc A6 +5M +12V I/O 2.5A 12.6Vdc 11.4Vdc A6 +12V +12V M 2.0A 12.6Vdc 11.4Vdc A6 +12 M -2V I/O 4.0A -2.2Vdc -1.8Vdc A6 -2V -12V I/O 2.0A -12.6Vdc -11.4Vdc n/a -12V M 250mA -16Vdc -9Vdc A6 -12M (unregulated) +30V I/O 250mA 42Vdc 22Vdc A6 J2 pin 4 (unregulated) The general thing to do at initial checkout is to adjust the +5V ADJ pot 'til the first of these is at +5.15 +/-0.05 volts, then check the other voltages to make sure they're within range. OK, so what about troubleshooting? There's a flowchart, which I'm not going to try to turn into ASCII, but here's the first question after you turn the machine on: are fans running? Beyond that...well, this flowchart looks like it's intended to help you troubleshoot to board level and in some cases transistor level. So supposing the fans are running, the next questions are whether +5V is present at the crossover board test point, and whether it is adjustable as described above. Feel free to ask questions, I'll keep the manual out for the next few days. -Frank McConnell

I sell family heirlooms (not yet, but it could happen) I sell items from the collection that mean less now than when I acquired them. I look for one-off consulting jobs that involve little or no work and put a small stipend in my pocket. I know when the yearly bonus is coming, and make certain I make the grade. I eat TV dinners instead of grazing at China Buffet; I avoid the temptation to order a pizza to be delivered; I stop buying grocieries onesy-twosy at the Dreary Mart and haul my ass down to Sam's and get a reasonable price. When I'm really desparate to acquire something, I even go back to making iced tea instead buying soft drinks; I can get a fifth of V.O.B. for the price of a pint of Maker's Mark, so I do that. I skip repairs to the Audi; on this one, the law of diminishing returns will kick in soon. Probably other ways I can't think of right now... -dq

DEC MUX cables free

by thompson＠mail.athenet.net

Recently I came across a variety of DEC QBUS MUX cables, and they are available at the cost of shipping. I have several BC19B-12 cables which go from the CXY-08 MUX to 4 DB25 RS-232 ports. I seem to recall someone from the list wanted one of these a while back. I also have large number of BC16D cables which connect a CXA-16 MUX board (the one without the full modem control lines) to the H3104 8 port banjo MMJ patch panels (also available). Let me know if any of these interests you. paul

Any AS/400 experts around?

by eric＠brouhaha.com

I'm now the proud (?) owner of an old AS/400, Type 9406 Model B45. Assuming that when we managed to let the rack fall on its side that we didn't destroy it; this is yet to be determined. Anyhow, I have very little (bordering on no) clue about AS/400s, so if anyone else knows about them, tips, advice, help, or the like would be greatly appreciated. The system came with about twelve Type 9332-600 disk drives (600M each), a Type 9348-001 nine-track drive (which is an HP 88780 with a custom front panel), and two terminals (but only one keyboard). It appears that the disks and tape drive are differential SCSI devices with Sun-style 50-pin D-sub connectors. I vaugely recall reading in the past that AS/400s use a weird sector size that is not a power of two; most high-end SCSI drives can be reformatted for alternate sector sizes. The CPU box contains: part feature upper lower slot number number connector connector function ---- ------- ------- --------- --------- ---------- 1 66X4709 3060 16M memory 2 66X4709 3060 16M memory 3 66X4490 3055 8M memory 4 21F5132 2513 processor? tamper seals! 5 93X2120 2514 ??? 6 93X2701 2601 50 female tape interface 7 93X2709 6110 50 female disk interface 8 46F4141 6130 ??? 9 26F5028 6031 50 male 50 male ??? 10 59X4270 6040 25 female ??? 11 93X2737 6110 50 female second disk interface? 12 blank panel 13 blank panel I guess that one of the cards in slot 9 or 10 must be an interface to terminals or to a 3174 terminal controller or the like. The IBM AS/400 web site doesn't seem to have any info on hardware this old. I'd really like to get an ethernet interface. I got factory-sealed 9-track tape distributions of two different releases of OS/400, four tapes each. I gather that there's some sort of license key needed for the software, so I have no idea whether I'll be able to install it. Naturally when I got the machine the seller didn't make any arrangements for a license transfer. For the price I paid I suppose it would be unreasonable to ask them to jump through hoops to do such a thing.

ID'ing VAX Boards

by jbmcb＠hotmail.com

I pulled a bunch of VAX boards out of an, I think, 8200 that was destined for the scap heap. How do ID these things? They are VAXBI and VAXBI-A, or whatever the CPU bus is. I've got a BUNCH (Around 15) I've ID'd one as a TK-50 Controller (It says it is) and an ethernet controller (DEBNT) Any help would be appreciated.

Yo

by jrkeys＠concentric.net

As stated long ago and as printed in the newspaper article done on me, my goal is to open a museum sometime in the very near future. I'm trying to get corporate funding and grants to get it off the ground. Right now I have stuff stored everywhere, such as 1800 sq ft warehouse in Houston (full), a 10x15 storage unit in Houston, two bedrooms in a house in Houston, 4- 10x15 and 1-10x20 storage units here in St. Paul, a one car garage full here, one bedroom full here in the apartment, and 5- 3x4x16 storage units in my complex here. I have over 3000 hardware items, over 1500 books, tons of old test equipment, and several hundred other types of items such cups, mousepads, mice, giveaways from trade shows (such as the items you send me each year from the VCF), I have computer art work (paint and photo), computer puzzles, computer toys, robots, and the list goes on. My wife says if I die before the museum is built than this all goes to the trashman. I started this back in 1985 and my dream of a museum started back 1992. But rising a family and working everyday was tops on my list at the time and now the kids are all grown and can go after my dream. I have gotten help from many on this list and hope that I can be of help to some of the new members. Well that enough history for today.

AFAIK the only monitor produced by TI for the 99/4(A) was a neat little silver composite monitor, with a vertical dimension of 9" or 10". I believe they were bundled with the original 99/4 for the bargain price of $1,200 or thereabouts. They were later available separately, but still way too expensive. I'd be interested in more details (especially the TI part number, usually PHP ####) if it is a TI badged 19" for the 99/4(A). Regards, Mark

Thrift Store find: Apple IIgs

ISTR there are multiple varieties; this one appears to be fairly old. It has a memory card inside with 256K of RAM soldered down, and spaces for another .75Mb. The ROM is version 1.0. Just playing around, I figured out how to get into the config menu and set background colors, 80 column, etc. I happened to have an external 5.25" Laser drive I got with my $15 IIc+ and was able to boot up the only DOS 3.3 disk I could find - Zork I. So... now that I have two machines that want to have 3.5" drives and no copies of DOS 3.3 on that medium, is it possible to aquire it anywhere? I have Macs, etc., so I can make a 3.5" disk from an Apple disk image if that's what it takes. Also, are there any ways I can expand this puppy? I happen to have a couple of old Apple double disk drives (the kind that came with the IIe); does anyone know of a diagram to make an adapter for the 19-pin connector that the newer computers take? >> sounds like you have the original model GS with 256k. later ones such as mine have ROM 03 and 1 meg. My GS also had a memory expansion card that I filled up to the max by using an XT's memory dip chips so most likely you can do the same. Nibble magazine used to have a program called dos plus which gave you two 400k dos 3.3 volumes on a 800k floppy. you can expand that GS like you would any //e or + except you dont need an 80 column card of course. the disk ][ drives you speak of can be used with a standard //e controller card if you like, or the apple // newsgroup members should be able to provide a pinout to cable those 20pin connectors to the unidisk port on the back of the computer.

WooHoo! I received two DecMate I systems today along with a Dec LetterPrinter 100 and an RX02 Dual Drive unit. I have some doc and software to go with them. Have to sort through it all. Problem is I promised my wife I'd go with her to the ball game tonight. Dang, now I can't check it all out until tomorrow evening. Oh well, at least this way she won't complain about having them around the house... not much anyway. Now the quest to get them up and running begins. Oh and thanks for getting the systems to me John, if you're still on the list.

Composing on paper, Green-bar, hardcopy output, card decks (L ong)

by mmcfadden＠cmh.edu

>From the Jargon file greenbar: n. A style of fanfolded continuous-feed paper with alternating green and white bars on it, especially used in old-style line printers. This slang almost certainly dates way back to mainframe days. This makes me feel ancient. The green bars were 1 inch wide which was 6 lines normal or 8 lines compressed. About 1979 I remember when I wrote a talk for a microbiology conference on my VT52 terminal. I then printed it out on greenbar which was used to prompt me during the talk. The greenbar proceeded to unfold down the front of the podium all the way to the floor. My boss was kind enough to indicate that the talk was really written by the computer. One problem with greenbar was that you had to turn it over if you wanted to print pictures or banners on the paper. Very long fiber paper, some of the cheap stuff was kind of like newspaper greenbar. I still have several cases of it, the fancy kind with printed line numbers. The nice thing about composing on paper was that once you wrote the same or similar thing several times by hand you decided to create a subroutine/procedure. Paper could be taken to the pool or outside, no electricity required. Composing on terminals was only practical when there were terminals available. Doesn't anyone remember coding sheets? If you are punching cards on an IBM 026 keypunch then any errors and the card was trash. The IBM 029 keypunch didn't actually punch the card until the end of the line, you could correct errors if you noticed them. Trash cards were useful for phone messages and notes. All of the JCL cards were usually a different color to allow the card decks to be split apart. I seem to remember pictures being drawn on the decks to allow the user to peer through the computer room window to see if your deck was due to be run soon. The best card run I ever saw was a 1976 run where the entire music list for the MU radio station was read in and then sorted by music type, performer, and title and then printouts produced. This happened on a Sunday when CPU time was free on the IBM 370 model 158 due to system testing. 12 boxes of data cards were read in and then stored on 9-track tape. Best input output/setup was in 1970 at CMU where the cards were read in and then output printed down a long series of sloped tables, each user got <10 minute response, they had a traffic light set up in the IO room. RED = system down, GREEN = system up, YELLOW = use at your own risk. They had a camera and speaker watching the printer to tell the users to change the paper on the printer. Worst setup was MU Computer Sciences where you turned in the cards and got back output in 24 hours. Many times with message CPU time exceeded and no output. Mike Coder from the dark ages

Free stuff!

by Marion.Bates＠dartmouth.edu

Hey -- Been housecleaning recently. I have several machines and some parts available to anyone who can come pick them up -- I'm living in Jacksonville, FL for the summer. Apple IIc and power adapter (works) Zenith 286 laptop (works) Apple IIGS (powers up, but I seem to remember it having some weird intermittent error message) Magnavox monochrome Computer Monitor 80 (works, small and lightweight, good for a testing bench?) Mac Plus with power supply problem, rest of it works 2 internal SCSI hard drives (230 and 260 MB), both worked last I checked 800k internal Mac floppy drive (dunno if it works) 400k external Mac floppy drive (dunno if it works) ImageWriter II (works, good cosmetic condition) Dead Apple Newton 100 with some accessories, manuals, etc. -- I think I fried something when attempting to resolder the loose audio wire Mac SE/30 (works, but if you take this, you are required to take the rest, too. ;-) And OT: some other electronic thingies, like a dead Sony Bookman and a Sega "simon says" game, if your tastes are that eclectic. Please email off-list for details, directions, etc. Thanks, -- MB

Programming on Paper

I think the immediacy of interactive programming causes the programmer to tend to exit the design loop early, before the design has actually crystallized in the mind. Working with paper provides the slowdown needed to allow this crystallization to occur. And now that I think about it... ISTR a paper by someone at Purdue during the 60s, a paper exploring the value of interactive computing (timesharing), and it specifically referred to hypothetical systems so fast that the benefits of being able to immediately submit a design to test would be lost due to the programmer jumping out of the design loop too quickly. But, to each his own... as long as they're not working for me. -dq
