It's possible I begin to manipulate the MP/M adn CP/NET sources to put it to work under Yaze. I must say you that I'd love to see all this manuals scanned and put together in some place dedicated to the CP/M stuff. If you can do it in a future then you're the better deposit. If you can't do it and can send it to me or another one who could scan it, it can be good too. Thanks and Greetings Sergio

History of Computing exam question

by mtapley＠swri.edu

Hans asked: >List the 20 to 30 systems you would display and briefly explain the >reason for choosing each. Fun question. Don't have time to really organize, but here's parts of my list: Napier's Bones digital solution for one class of computing problem Slide Rule (almost any) Analog computation, and portable computing power. Application of a fairly disjoint set of technologies to a very focussed solution that met a serious need in engineering Abacus (almost any) As with the slide rule, but now a discrete digital technology. Babbage's Engine ...or plans, if it couldn't be found or made a replica of. Large-scale compute power, digital technology with the greatest flexibility so far Bowditch's "American Practical Navigator" and a sextant Illustration of the market drive for computing power, and the tabular approach to meeting heavy-duty geometrical calculation problems. (Could just as well be the old Admiralty tables, I'm just biased in favor of Bowditch 'cause I'm American.) Zuse-1 (fill in the blank) Enigma machine, and Bomb (a matched pair) *serious* market drive -> compute power response for a single application Eniac (fill in the blank) IBM 360 (fill in the blank) PDP-11/xx Pick a good one, first minicomputer/lab computer. Brought compute power into a lot of lower-cost applications. Dec Rainbow typifies both MS-DOS and CP-M machines. somewhat breakthrough OS flexibility, (MS-DOS, CP/M, CCP/M, Venix, all of which were preexisting). Mac 128k GUI OS for the masses, origin of "friendly" computers (first computer to *smile* at me). VAX - any Illustration of successful extension of an existing architecture to more bits (twice as many) Alpha - any As VAX, but to 64 bits/RISC Cray 1 Vector supercomputer, electromechanical design breakthrough Newton PDA origin. Perq microprogramming, early workstation, heck Tony likes it so it must be good... F-14 flight computer integrated circuit microprocessor first application (?) NeXT Cube (original) OO system, sizeable leap in developer environment quality Sun Sparc-5 Desktop workstation, power/price/size breakthrough Sony Vaio or Mac Titanium Laptops get to practical size and retain serious power. DVD player (any) or CD player market driver for serious compute power cheap Sony PSX as above, including graphics Jet engine FADEC unit (any) compute power seriously ruggedized and making a pilot's life easier (livable). I'm sure I've left out a lot, apologies to all concerned. - Mark

More E-Bay Insanity?

by Robert_Feldman＠jdedwards.com

Yes, but this one's being sold as "unopened." The seller thinks it has value to (or that he can make a bundle from) a _collector_ rather than a _user_. If anyone buys it, I doubt that they will ever open the package. It is madness, but (as has been said many times before) the value of something is what someone is willing to pay for it. -----Original Message----- From: Christopher Smith [mailto:csmith@amdocs.com] Sent: Monday, December 03, 2001 4:12 PM To: 'classiccmp(a)classiccmp.org' Subject: RE: More E-Bay Insanity? <snip> ... ok, I understand this perfectly (believe me!) but this is a head cleaning kit, and anyone who's still got a 5.25" disk likely could take it apart and clean the head without the kit.

VERY LONG: Latest S-100 Haul

by r_beaudry＠hotmail.com

Hello all, Thanks to a VERY generous man, located about an hour's drive from me, I have a boatload of CompuPro S-100 stuff, 8" floppy drives, manuals, software, etc. The list is long, and I debated posting it here, or linking to a web page. In the end, I decided to post it here because I wanted it to be in the archives in case anyone was looking for any of this stuff. I am more than willing to copy floppies or manuals, no charge but postage (and you supply the 8" media, as I am VERY short of blanks). The only caveat is that it may take me a long time to do it, mainly becuase I'm not very organized :-) Before the list, there were also two Osborne 1 computers, one with a dead internal monitor (but works from external monitor), and one fully functional, with the double-density upgrade. Also, manuals and full sets of original disks for each. Without further ado, here's the list: CompuPro chassis, 21-slot motherboard - 1 Full CompuPro RAM22 board - 1 Full CompuPro RAM22 board - 1 Full CompuPro RAM21 board - 1 Full CompuPro RAM16 board - 1 Full CompuPro RAM17 board - 1 Macrotech Dual Processor board -- 80286 and Z80H - 1 CompuPro System Support 1 - 1 CompuPro DISK3 Hard Drive controller - 1 CompuPro Interfacer 4 - 1 CompuPro DISK1A Floppy Drive Controller CompuPro System 8/16 Chassis, 20-slot motherboard - 1 Full CompuPro RAM22 board - 1 CompuPro MDRIVE/H 512K/2 MEG disk emulator board - 1 CompuPro CPU68K board - 1 CompuPro System Support 1 board - 1 CompuPro Interfacer 4 board - 1 CompuPro DISK1 Floppy Controller Board Three dual 8" drive units (one CompuPro, two no-name) -- The CompuPro unit has two QumeTrak drives (242, I think -- full height 8"), one of the no-names has two Shugart 801 drives (single-sided only, I think), and the other no-name also has two QumeTrak drives. Unfortunately, the power supply in the no-name QumeTrak drive box literally had an LM723CN explode, breaking the chip in half, melting the socket, and fusing two pins to the socket. Cheap enough for a new chip, but time to put in a new socket, and figure out if something else has gone bad...

Scrapping hardware to get it off the books (RE: Is it a Lisa or Mac XL?!)

by mythtech＠Mac.com

>Should I even bother going back and asking to see the stuff >in the yard? Or, has this firm agreed not to resell anything >(I'm kinda assuming that what's true for this guy is industry >standard). I don't know the laws, but why shouldn't a scapper be allowed to sell the stuff in working condition? They are in the scrap business, and I would think once it is theirs, they should be allowed to sell it however they want (pulverize and sell as land fill, or repair and sell as working). Is there some law against selling the stuff in working condition? -chris <http://www.mythtech.net>

Dave- My subject line included a question mark; I wasn't making a declaration, I was posing a query... Radio Shack sold these cleaning kits for years for, what, $5.95? Now, and I don't know, perhaps RS doesn't sell them anymore. I don't have a Jameco catalog handy to check, though I could look at a Global catalog... at any rate, I'm wondering whether this might have been a typo that the seller didn't catch... -dq

DEC Infoserver 150

by Adrian.Graham＠corporatemicrosystems.com

Hardware wise the Infoserver 150 is a MicroVAX 3100 Model 10. Software wise I never got any real chance to hack mine and ATM it's in my storage room along with a VXT1200 X-terminal, which was the reason the 150 existed in the first place - one of the popular DEC bundles of the day was an infoserver and 5 VXTs. The software uses the Local Area Disk protocol (LAD/LAST) for disk services which requires a client to be running on a VAX somewhere (SYS$MANAGER:ESS$STARTUP.COM). VXTs could boot using IP/BOOTP/TFTP. There must be more than just ROM changes to the hardware though. I used to think that the whole reason the 150 came about in the first place was that Digital had a small mountain of 3100/10s lying around so they did their usual trick of using old hardware for new tricks (viz: RL02s as console media for bigger VAXen (6xxx?), PRO380s as consoles for 8xxx's etc). The 150 was superceded by the Infoserver 1000, which was smaller than the RRD42s that it controlled. > > Hi folks. I got a few questions.

Off-Topic: Re: Anyone have a MicroVax II in a BA123 available?

by r_beaudry＠hotmail.com

<RANT> Why is it that anytime anyone asks: "Does anyone in my small geographical area have a 'foo' they want to get rid of?" there is invariably a slew of "I have one, but don't want to get rid of it" or "I have one I want to get rid of, but not in your area, and not willing to ship" messages? If you're not in the area, or you don't want to get rid of it, why reply? I mean it's gotta be annoying to the original poster to hear of others in the area, with the "foo" he needs, but who don't want to get rid of it. It's not bad that they have the "foo", but it seems like the reply is rubbing his face in it.... </RANT> Rich B.

Value is in the eye of the beholder, man. Why is it automatically "insane" when someone else views omething as being more valuable than we do? The resale value of the stuff we hack on is going up, and we have to learn to deal with it. It has been for some time. People are buying it at these prices, and it's not just one or two people. Let them spend their money...if they're happy with their purchase, what's wrong with it? Further, one mustn't lose sight of the fact that different things are more readily available in different geographic areas than in others. Just because there are fifty AppleIIs at the corner yard sale in your neighborhood doesn't mean there are fifty of them at EVERY corner yard sale. As a case in point...I'm no newcomer to this field; I've been doing pdp8/pdp11/vax stuff for a solid fifteen years. My first real system was a pdp11/34 which I sold about ten years ago, and have regretted it every since. I've wanted another one for several years, and had been looking for one in earnest in the Washington DC area for a solid three years...never managed to get one, and believe me, I know where to look. I finally bought one locally for about $400, indirectly from a surplus dealer who was sharking on the "antique computer craze" trying to make a ton of money on it. I'm sure he got it for free, and he laughed all the way to the bank. However, I'm VERY happy to have it, and I love the machine. If I hadn't paid that $400, I wouldn't have one. They're simply unobtainium in the DC area. -Dave -- Dave McGuire St. Petersburg, FL

I'll agree it, sincerely. My doubts are, mainly: * Can I connect the hub directly to 220 volts AC ? It appears possible if I've read correctly the AC connector info. * How must I connect the RG58 cables ? Must I put a Ethetnet 'T' with a terminator in the computer BNC connector or not ? * Finally, the link connectors and you suggestion about the link to one managed hub. Thanks and Greetings Sergio

HP ".fst" format

by bill_mcdermith＠yahoo.com

I scrounged a copy of the RTE OS for the hp21xx computers, but it is in some strage archive format with the extension ".fst" -- this is apparently much like tar, but my sun version of tar doesn't uunpack it well (to say the least :-)... Does anyone know of either a version of the archive program for this format that I could build on a UNIX box, or the format of the file so that I could unpack it? Thanks much, Bill McDermith

Groups in Houston (and elsewhere)

by acme_ent＠bellsouth.net

Have any of you Houston folks looked around for similar groups in your area? A quick Google search of my (Orlando) area found an Apple II group and an IBM PC group, both of which hold monthly meetings. There are probably similar groups in your area where you might meet vintage computer people (other than those on this list). Glen 0/0

DEC PC04/PR8E Question

by healyzh＠aracnet.com

OK, the last part of my shipment just showed up, the Papertape reader. I'd thought the PC04 was a reader/punch. Am I correct in my revised assumption, that it came in three models; reader/punch, reader, and punch? Now for the first question, should there be anything on the right side (looking from the front) if it's only a reader? For some reason I've a bad feeling that I don't have a complete reader... On a positive note, the PDP-8/E looks to be in *far* better shape than I'd been lead to believe, so hopefully I'll be able to get it up and running with minimal effort (I could be so lucky). Though it's large enough I'm very tempted to transplant pieces into my PDP-8/M and put the /E in storage. Also I got a terrific looking pile of documenation and Volume 3 of the hardware manuals is twice the size of the copy I already had. Most of the manuals are ones I didn't have, and I've finally got a printset :^) Zane -- | Zane H.

IMPORTANT NOTE (list admin)

by west＠tseinc.com

The classiccmp mailing list, as well as all the classiccmp related websites that I'm hosting at no charge, must be moved IMMEDIATELY to another set of servers at another location. Due to possible legal contractual reasons, I can't publicly go into more detail. If you need further information about this just contact me off list and I'll see if I can be more specific. PLEASE keep the following points in mind: 1) PLEASE do not continue (reply to) this thread on the list, I'd rather not have a bunch of messages in the archives about this topic. If you want to say anything about this, only reply to me at west(a)tseinc.com 2) I have resigned from the company that I worked for, and am no longer an owner there. The only valid email address for me is west(a)tseinc.com and to anyone who had my cellphone number, I now have a different number. Contact me via email if you need it. 3) Anyone who had my USmail mailing address for shipping stuff to with a zip code of 63117, please dont send anything there as there's no way to be sure I will ever get the package. Contact me off list for new mailing info. 4) I will continue to have the classiccmp website as well as all the free classiccmp related websites hosted at no charge. My offer of free hosting for any such websites or mailing lists still stands. Nothing will change, only the servers the sites are located on. The new location where the sites will be hosted is every bit as robust and well managed as the old location. 5) I took extreme pride in our uptime and reliability. You can assume the same will continue with the new hosting location (wink wink). However, as much as it truely pains me to do so, the sites and list must be moved in a very unplanned, hurried, unceremonious fashion. It is certain that there will be some downtime for the mailing list, as well as some of the free sites, WHILE they are being moved - lasting possibly 48 hours. I sincerely apologize for this, but the situation forces me to do this in an abrupt manner without planning for DNS propagation and the like. My sincere apologies. 6) As I said, the offer of free hosting still stands now and in the future. If anyone has any classiccmp related sites or mailing lists they want hosted, just drop me an email. Regards, Jay West

Hmm, well, that's (almost) the worst example I've ever seen :-) You're supposed to stop one position shorter each time, because by the end of the sweep, the largest (or smallest, depending on which way you do the comparison-and-swap) number has fallen to the bottom (end) of the array.

I doubt it was the first machine to have any of that. A VAX-11/750 with a vt-100, for instance, would have had all that less the dual-floppies and with a much higher maximum RAM limit ;) Seriously, though, some older CP/M boxes also had real keyboards, decent displays and dual floppies. (Some of which was optional, mind you... as were _any_ floppies on the PC, AFAIK, in that you bought them separately :) Also you could say that it was the first available 16-bit home computer (depending on your definition of 16-bit), but you'd be wrong... (Quick search says that several people believe this was the TI-99, actually, which also had a real keyboard, and could have had the dual floppies) Ultimately, the 32-bit systems were pretty close on its heels -- I have a timeline that places the PC in '82, and the Apple Lisa in '83. I don't know if this is correct... I have no idea how the peesee actually lasted as long as it has. There were several 32-bit systems on the market by 1984 or so (though, my personal favorite was done in '87 with the Acorn Archimedes).

3com 1625-0

by spedraja＠ono.com

Dear fellows, thanks to all for the messages received until this moment about the MV 3100. With independence of this lovely machine, I have one new question. This can be difficult, I've located only 4 hits in Google and all of them referred to catalogs. Somebody has one 3com 1625-0 Coaxial FMS Hub ? I just received one. It's supposed this item has one variable voltage power supply that covers from 110 to 220 volts. Right ? It has too eight coaxial connectors, one AUI connector in the back, and... a couple ot mini-scsi connectors, one male and one female. The most dammned strange combination I saw until this moment. Do you have some info of interest about this item ? Thanks and Greetings Sergio

It has two connectors of Centronics type. One is a large Centronics type connector, over the three MMJ connectors.

I have a DV-31BTB-A which I know is a MicroVAX 3100 Model 20. Yours, according to the Systems & Options Catalogue I have, is a MicroVAX 3100 Model 10. On the back of mine there is (looking at the back): at the top middle: a DB37 labelled B2 (this is a socket with 37 pins) (I don't think this is available on the Model 10) in the middle row (from left to right) a connector labelled (4-11), this is for an asynch card (DSH32 I think) This is the same "style" as the SCSI connector (i.e., no pins) but is smaller. It is *NOT* a SCSI connector. another DB37 labelled DB37 this is over and slightly to the left of the 3 MMJ connectors. a final connector on the right, labelled with a diamond and a horizontal line through the right hand point. This is the SCSI connector. This connector is the only one that is identical to the connectors on the TK50Z. This is over the printer connector. Having said, if you have the right SCSI cable (i.e. the same connector at both ends) then I don't see how you can possibly have connected to the wrong place. (And it sounds like you have used the RIGHT hand connection and just are unsure what the other one is). BTW: The TK50Z box has two SCSI connections. It does not matter which one you use, but you *must* put a terminator on the other one if you expect the MicroVAX to see the tape drive. I've found a manual with pictures of the connectors. I can scan some pages on Wednesday and email them to you directly if necessary. So a few checks: -- are you using the correct (RIGHT hand) connector? -- Is the unused connector on the TK50Z filled by a terminator? -- What ID is the TK50Z set to? (Avoid 6 & 7 ... the CPU uses one of those ... I forget exactly which because it varied from system to system). -- Avoid any ID used by the existing drives, SHOW DEVICE will list these. The external SCSI bus may well be independent of the internal bus, in which case it will not matter, but again I cannot remember for this system. -- If it still does not work, what to the power up tests say? The error code (if any) should help to track this down. Antonio arcarlini(a)iee.org

I was very lucky (I guess) because I was able to get back on the servers Sunday morning to change my account. I am no longer mranalog(a)home.com, I am now mranalog(a)attbi.com. AT&T says that some customers may be out of service for as much as 10 days. Of course, my service was back just long enough yesterday for me to resubscribe to to a few discussion lists and then it was out again.

PDP-8/E bulbs

You may also > be able to find them at: http://www.digikey.com Hmm, I'd not be too sure about that. I believe the correct bulbs are 12V or perhaps 14V, T1-3/4 bi-pin, 0.04A (that's 40mA). I've seen 14V 80mA bulbs in a few places, but I'm not sure if they would be "safe" in the panel - they'd draw twice the current and I'm not sure if the driving transistors are rated for that. Anyone know? (I have a panel, but not a print set). If it's any help, I found some of the proper bulbs for my -8/E recently, and they are marked "OSHINO-1 12-09169" or "PL10161 1209169". I think the 12-09169 may be the DEC part number. On test, they draw between 30mA and 35mA at 12V, and between about 35mA and 40mA at 14V. The ones I've found in the Farnell catalogue (cat no 329-216) seem to be made by EBT Technologies, part no 7382, and they're 14V, 80mA, 1.12W, 3.8 lumens, nominal life 15000 hours, priced around 50p (about 72 cents) depending on quantity. I found the same bulbs slightly cheaper in the CPC catalogue, for those of us in the UK. -- Pete Peter Turnbull Network Manager University of York

OTOH, if it happened during the Jobs era, no logic or reason was likely involved; Jobs has a proven track record of killing Apple products he personally dislikes. But pepsiboy may have been Lisa's nail-in-the-coffin, I just can't recall... -dq

by msell＠ontimesupport.com

Hello, I saw a couple of MicroVax II's over the weekend and they look like good project machines. Does anyone in the Houston, TX area have any they want to part with?

Scrapping hardware to get it off the books

by DAW＠yalepress3.unipress.yale.edu

! From: Chris [mailto:mythtech@Mac.com] ...... ! But I will take anything Apple related that people will just give me ! (although not everything stays with me, better useable macs ! get given out ! to people that can't afford a computer... for instance, the ! Classic II I ! got from David I am giving to someone for Xmas that has no ! computer, the ! kid can at least use it for writing school papers, checking ! email, basic ! web browsing, and playing some games... it is a step ahead of the ! nothingness he can use right now). ! ! -chris Well, I should've just sent the LCII along also, if I knew that. No-one seems to want it! --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818
