Free to good home: HP MDP module, P/N 5062-3054 - Can't test it since I don't have a 9000/K type Dell Pentium cache module (big DIMM type card) Also, I have a friend who has a HP 9000 Series 800 H50 server box (it's been unracked, but fits nicely under the desk (he gave me the one from another rack- runs HP/UX 11i just fine) Somewhere between 512 and 768 MB RAM, single 96 MHz processor, several HP-PB cards it's sitting in my garage, and he's given me permission to see if anyone wants it. He does audio recording, so if anyone has something to trade for it in that field that would be good, or we could do a 3-way trade (I'm interested in classic computers, I can get him what he needs, we're all happy...) Heavy beast (~70 lbs) so pickup would be easier than shipping, but shipping could be arranged. If no-one wants to trade, I'd try to talk him into giving it away. I'd rather it get used than sit in a garage. Reply off-list, etc.

Good news, bad news....

by zmerch＠30below.com

The good news: I found my Tandy 200 and repaired it. (All it needed was a new internal NiCd battery, but by the time I found the battery, my wife lost the computer! :-O ) Upgraded it to 72K RAM as well, so I'm really stylin' -- ready to rock with it. It's 20 years old this month! More good news: I found my 200 packed under my STacy 2, which I need to repair. It's got a boatload of dodgy solder joints in it... and now that I finally have a very good soldering station, I can work on repairing that as well! I can repair it... but sadly, I cannot *reassemble* it as the baggie with all the screws for it (mostly case screws, but some board screws as well) was *not* packed with it; and so their location is still unknown. Anyone know the size/thread pitch of the screws in a STacy? Thankz, Roger "Merch" Merchberger -- Roger "Merch" Merchberger | "Profile, don't speculate." SysAdmin, Iceberg Computers | Daniel J.

by dlormand＠aztecfreenet.org

Age is 43, started trying to build 6502 machines after being exposed to a KIM-1 in college. Then tried to build 1802 machines. Actually got one to sort of work! Then I talked my dad into a TI-99/4A for "writing school reports" (which it did, plus a whole lot more) and have stuck to it. Now have several full-up 4A rigs plus a Geneve. Also played with Atari STs and Falcons, and dabbled with an 800 briefly. Now (in addition to the 4As) have several 386es and 486es running a variety of FreeDOS and linux, and a Slackware main system next to the Geneve and the 4Mb 520STfm. I learned programming in FORTRAN using punch-cards on an IBM mainframe at school, where I met a fellow who had built an 8080 machine in a file cabinet in his dorm room, and programmed it using punch-cards from the Computer Center. I have played with several VAXes over the years at work, including an intimate experience with VMS 4 on a MicroVAX II that was running the TI cross assembler for our TOW missile launcher software development (based on the SBP9989, a close relative to the 4A's TMS9900 and Geneve's TMS9995). Played peripherally with a TI 990 mainframe and programmed a real-time hardware-in- the-loop simulation on a 68000 ExorMACS. All in all, it's been a blast, and I wouldn't change a thing!

server maintenance

by jwest＠classiccmp.org

Got all the websites moved. If any of you have trouble with your website on the classiccmp server please email me directly. Now I'm working on the last bit... going through the archives and rebuilding them. A bit more of a pain than I'd normally think, because the mailman archive rebuild program doesn't handle large files which of course the mbox files are. So I'm having to break them up by date ranges and import individually. There doesn't seem to be much in the way of programs to manipulate and break up mbox files, so I'm writing ditty's to do it. Once I'm done, the archives should be back up, and searchable with HtDig!!! Jay West

DG Nova 4/x software hacking

by tomj＠wps.com

Well I seem to be heading towards a usable computer. Sat down with the manual and re-learned nspeed. First task was to write a script to create links in the working directory to all the utilities on DP0. Used the BUILD command (builds 'command tail file lists' in unixese), and wrote an iterative macro to hash it up. (There's no "path" to find executables (.SV); it must be in the current directory or directory specified. Directories in RDOS aren't heirarchical like they are in unix-derived paradigms; they're like little partitions, you more or less "mount" them with the DIR command (mounts the directory and makes it default directory) or INIT them ("mounts" them so you can copy to them, for instance.) You specify how many directories you can have mounted at the same time at SYSGEN time.) Build makes: ASM.SV,MAC.SV,FDUMP.SV,FOO.SV,BAR.SV, [and so on] I needed: LINK ASM.SV DP0:ASM.SV LINK MAC.SV DP0:MAC.SV ... The nspeed command is: 32<1BTABSAJ#C $ $BS0ILINK ^BA DP0:^BA $-1LT1L> Here's one of those maddening things that I'll figure out someday, and has some dubious reason. The command: S $-1D (Search for a CR) S $ (Delete 1 char before pointer) -1D Works fine maually. It doesn't work when iteration < and > is used! That's why I change all occurrences of CR to space in buffer A: #C $ $ That works. ^BA means 'insert the contents of buffer A' -1LT1L minus one line; type out line; plus one line, so it prints the results of edits as it goes. The leading 32< ... > Means 'iterate 32 times' because I didn't feel like coming up with a test for 'end of buffer'. Eh. Now to write a HELLO WORLD program!

Age and Computing History

by list＠saracom.com

Well, Well born in 1963. I had always been interested in electronics and such. My first computer experiences were in high school. The school had a TRS80 Model 1 and accounts on the university's PDP11/45. I had bought a CoCo 1 with 4K! This was in my senior year. I go to the same university. It was Western Kentucky University (WKU). They still used the PDP11/45 with RSTE. Additionally, they had access to UK's IBM 360 via a smaller PDP11 with a card reader. So I got started with card readers and terninals. We ran a pirate exchange with the microcomputer lab etc. Fun times. I ended up buying the PDP11/45. Unfortunately a unplnanned move ocurred and I could not find anyone to take it. So sadly it went to the scrappers. This was before the Internet. I did keep the console panel. Max

(List) Communication Options...

by dvcorbin＠optonline.net

>>> >>> Seriously, what do you reckon would be a "proper forum" >>> for international discussion of classic computing? >>> At the risk of being labeled a "Heretic" or worse. And with an upfront statement, that this in no way reflects on the fabulous work being done by Jay..... Now this *might* lead to something interesting.... A few thoughts (in no particular order) 1) Given the nature of the list, compatability with a _reasonable_ selection of classic computing enviroments needs to be maintained. This should not preclude the usage of _newer_ technologies where appropriate. 2) "Conversations" should be easy to follow, with minimal requirements on the behaviour of the user. For example if there are 100 consecutive messages on a topic (each one in direct response to the immediate previous one), and someone replies to message #68, then it sould be easily identifable as such. 3) Bandwidth (client and host) as well as storage requirements need to be considered. 4) Digest, "Immediate Message" and On-Line Access would all be useful user interfaces. 5) Searchability [by members and services such as Google] is important if this is to be used as a reference site. 6) Organization (above the distinction between ccTalk and ccTech) would be beneficial. Being able to filter messages for a specific computer vendor or other simiular trait would be helpful. 7) Maintenance/Management issues should be kept minimal since there is no paid sponsorship for the list [to the best of my knowledge]. 8) Elimination of redundant information (i.e. duplicated from post to post to post) while still retaining context. That is just a start from my "wish list" view of communications. There are many issues with making any changes to the method of communication that would need to be addressed, and members feelings would be among the top. <<<< now to go down and look for the C User Journal CD I promised a list member....

> It could be interesting to know the age"spread" of this list contributors, > and how long we've had the computer virus under our skin. 1960; Been keenly interested in electronic and technical things for as far back as I can recall ... As a child I spent all my time "building things", but didn't really get exposed to computers until the mid-70s when I fell in love with an IBM 370 (See below)... First computer of my own was a homebuilt 8080, followed closely by an Altair 8800 (which I still have). Long and highly varied list of machines follow, including several more homebuilts. Never an "appliance operator", I always used the machines as a creative outlet. Always been interested in low-level and systems type aspects, designed my own interfaces, wrote my own operating systems and development tools - still use mostly my own software, although I have a couple systems configured with winblows for "when I really have to". Pretty much the same story professionally, worked for various high-tech companies, got caught up in it for a while - did a few "salvage jobs" where I was came in to "rescue" a project after "the team" had spent all the money and had little to show for it, eventually became a director at one of the major telecom players ... at which point I realized I was rapidly leaving the relm of "hands on", so I stepped off the ladder. Turned my hobby into a business, and I've been hawking my embedded systems software development tools and contract services for the past 15+ years... (and being much happier for it). Regards, Dave ---- (below) ---- For those who didn't experience IBM mainframes - IBM was not always just another player in the "me to" Wintel market - in the 70's, they were one of the major forces in the computing industry, and to our university computer center which was built around the IBM mainframe, at times they seemed like denizens of Mount Olympus. Here are a couple of my "favorite IBM moments" from that era: ---- At the University of New Brunswick, we had mostly serial TTY terminals, however at one point they brought in five IBM 3270s which were set up at one end of the user access area. The idea of being able to "instantly" write an entire screen page was really cool, and in short order I wrote a "tank game" where multiple people could enter a virtual maze and shoot at one another, which pretty much realtime updates of the visible maze and other players. It was very popular, but due to a bug somewhere in the system, it had the undesired effect of crashing the entire mainframe. (They had a "traffic light" in the access room, which would show Green when the system was up and running, Red when it was down, and Yellow if it was scheduled to be taken down shortly. Invariably, a short while after a couple of people started up my game, all the TTYs in the area would stop responding and shortly after that the light would switch to red). My "favorite moment" came one Sunday morning, when the computing center announced that the system would be unavailable for the day (a very rare occurance) - I came in to see what they were up to, and found the access room empty except for 5 guys >from IBM, complete with suits, ties and briefcases - sitting at the 3270 cluster. Four of them were playing my game (and making some favorable comments), while the fifth guy was madly running diagnostics, scrolling through dumps and generally trying to figure out what going wrong - they did find it, and after that my game no longer crashed the system (although it still cost a small fortune in processor time to play it!). ---- Fairly early in my career, I worked on developemnt software for a 6809 based test system at Mitel - this had a CPU/RAM card, and various interface cards. One of the hardware engineers had designed a floppy disk controller for it, however software support consisted of a monitor program with commands to read and write tracks/memory. On my own time, I wrote a decent multitasking operating system and disk file system for it, and when I demonstrated it, the company formed a new devision to develop this "advanced test system" - I was in charge of the operating system, languages and development software ... We ended up selling quite a few of these to IBM, and having been launched on my path by my experiences with IBM MVS, I took great pleasure in the thought that they had bought and used *my* operating system (yeah, I know - to them it was just a piece of test equipment... but at the time it was a "favorite moment"). -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Collector of vintage computing equipment: http://www.parse.com/~ddunfield/museum/index.html

Age spread stuff.

I myself am 23 (I'm probably one of the youngest members here), born 1981. I guess you could say that I'm a second generation classic computer user. Anyhow, I cut my teeth on an Osborne 1 that my dad owned (that he hooked up on old Amdek B&W monochrome monitor to), as well as the Apple //e & //e platinums at primary/elementary school. After that it was primarily PCs from there on (what can I say, I was the generation that got corrupted at an early age!). It remained that way until 1998 when I was given a Commodore 64C (which I still have and has been heavily expanded since then), and now, well, have a look at my collection now! ;) David M.

I never saw a computer until I went to college in 1976 and met a PDP-11/40 running RSTS/E. I lived on the computer for the next 3 years until it interfered with my grades and I had to spend time on classes instead. I got a programming job in 1981 in RPG on an IBM S/34 immediately after college and have been doing software development ever since, on IBM mainframes (COBOL, CICS, Assembler, ADS/O, etc), PCs (Basic, C, MASM, OS/2 PM, Visual Basic, IIS based web development), primarily Microsoft platforms, taking occasional breaks from programming to dabble in the management side of things and fly around the country doing requirements studies, marketing, training, etc. I always tire of corporate management and politics after a few years and get back into the programming side of things until they twist my arm and talk me back into management stuff again. I've been in this cycle of management/ technical flip/flop since about 1986. For the past 20 years I've been involved in development of software for the insurance industry. Ashley

AIX and AMIX questions

by doc＠mdrconsult.com

What a mix, right? First the AIX stuff. v2.2.1, definitely on-topic. My RT has been laid up with a failing IDE disk for a while. The E70s that it came with were serious junk, and near death. I now have a couple of Maxtor ESDI disks to play with, and I also found a 1.2GB Medalist that should work in it with the IDE/floppy controller that's presently in it. For power/BTU reasons I'll go with IDE if possible. The problem is that the AIX floppy images are no longer on the dementia.org FTP site, and I've stupidly lost my archive of them. Does anybody happen to have them stashed away? Floppy images are nice, or I have the sort-of-SCSI 1/4" tape streamer and adapter too. For whatever it's worth, my company is an AIX software and services partner. That means I can legally have any version of AIX needed to do or to properly research my work. :) While I'm at it, does anybody have an RT mouse they don't want, or a Matrox graphics adapter? On to Amiga UNIX. The little information I can find about installation (see rant below) says that the original v2.x requires a Commodore 3070 tape drive, which is an Archive Viper-150 in an external enclosure. I don't have an Archive drive, but I do have an IBM-firmwared Tandberg TDC 3600 an a Sun-firmwared TDC 4220, both of which are QIC-150 compatible. The first question is whether AMIX looks for Commodore firmware on the tape drive, or will any 150MB quarter-inch drive work? The second question is whether install media for AMIX v1.x exists in downloadable form? <rant> Somebody mentioned "more appropriate fora for discussion" the other day. Well, the only active AMIX forum seems to be a freakin' MSN Group. Since I don't have and don't EVER want an MSN .Net Passport, I don't get to play there. Do they think all the world is already owned by MSN? </rant> Doc

Well, first off, I was born in 1986, so I'm 18. A bit young, but there you go :) Let's see.. where to start.. Well, the first computer I actually used was an Acorn BBC Micro (Master 128 if I remember correctly) in primary school (age 8 or so). I talked to the IT teacher and she let me borrow the manual and some BBC BASIC guides. At the parent's evening that year she spoke to my mother and apparently said "Get this kid a computer!". I got a Spectrum +2A fpr ,y birthday, again with a load of programming books. Wrote a few games, then hit the limits of the hardware. A year or so later I had a fairly high end 486SX/25 with 4MB of RAM and a 160MB Conner hard drive, MS DOS 6 and Windows 3.1. I learned QBASIC, then Visual Basic, then didn't really do much programming until '96, when my uncle let me borrow his copy of Delphi 1.0 for the weekend (including the manuals). I learned ObjectPascal from that :) In '98 or '99 I managed to scrape together enough cash for a 56k modem, then got an account on Freenet UK - my first internet connection, on a K6-II/450. All of 56kbits a second. IIRC, I joined classiccmp in 2000 (might have been a bit later), then joined the MIT PICLIST a few months later. Getting ADSL in '03 really made the mail downloads go quicker - I've had my own fileserver running since mid-'02, late-'03, running Linux. As far as programming skills go - I know C, some C++, x86 assembler, PICmicro assembler (12, 14 and 16-bit varieties -- PIC12, PIC16 and PIC18 devices), QBASIC, Visual BASIC (DOS and Windows versions), Pascal and BBC BASIC. Other hobbies: Well, electronics is the main one. I'm entering the Parallax (www.parallax.com) SX Design Contest - all being well, I should be able to get the firmware for my entry stabilised within the next few hours. It's gonna be a long night! :) I'm a real tech nut - I won't go anywhere without my Minidisc recorder (Sony MZ-N710) and my mobile phone (Nokia 6210 or Samsung V200, depending on which one's charged at the time). Oh, and I've got a bit of a reputation for destroying hard drives when they fail. Usually with big drills and hammers. I'd love to see a thermite reaction melting a defunct IDE hard drive down at some point though :) Gee, I've just written most of my life story.. maybe I'll put this post on my website at some point :) Later. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem at philpem.me.uk | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.me.uk/ | 48xCD, ARCINv6c IDE, SCSI ... I believe I will take this opportunity to remove my ears.

I've been interested in electronics for as long as I can remember, I built my first transsitor radio about 32 years ago. I've never really been interested in programming/software, I'm very much the hardware type. The fact that computers are interesting pieces of heardware is why I collect, restore, etc them. This might explain why I like to keep the hardware of my machines as original as possible, even for things like power supplies. The power supply _was_ part of the original design, it should be preserved (and if you think all SMPSUs are the same, then, boy, have I got news for you...) My first computer (not suprisingly) was a Sinclair -- in my case an MK14. That put me how his designs for life. I've used some of the others, I've never found one I consider to be even moderately well-designed. I then got a TRS-80 Model 1, used Beebs and RML380Zs at school and fooled around with some other micros. Then I went to university and picked up the Philips P850. Chatting to a friend about it that night (this was some 19 years ago), we realiased that unless something was done -- and fast -- a lot of computer history was going to be lost for ever. At the time, museums were not bothering to preserve common micros and minis. So we did something about it. We (I suspect particularly me) started collecting everything we could get our grubby little hands on. The rest, as they say, is history... -tony

server maintenance progress

by jwest＠classiccmp.org

So far the list looks ok, and I'm going through all the classiccmp related websites and getting them up now. I have noticed that the new server seems to be very slow in delivering posts compared to the old server. This doesn't make a lot of sense, given the old server was a 1.2 P3 and the new server is a 2.0 P4. Go figure. However, since it seems to be working, I'm going to continue with the website migration and complete that. Then I'll turn back to the mailing list and find out why it's running slow, and, then finally start the work on the archives. Regards, Jay West

> After French took over the RCA, they started putting weird location > marks: It goes like this: LL005 for fly, TL00x for transistor in > horizontal, TV00x for video transistor amps. So on. Totally That second character 'L' might well stand for 'line' which is the conventioal name for the hoprizontal deflection system over here. We talk abvout the 'line output trnasistor' where you'd say 'HOT'. Were the transistors in the vertical stages called 'TF00x'? 'F' being 'frame' or 'field' depending on how old you are. -tony

I don't 'choose to use old hardware' I use what I consider to be the best solution I can get (and afford). That does not mean the latest, it doesn't necessarily mean the oldest. I do however refuse to use anything I can't fully understand and/or maintain. This does, alas, rule out much modern computer hardware... > reason for not making use of features that are available on even mildly > modern hardware. > > Should movie producers ONLY produce black and white movies because some > people only have B/W sets? _VERY_ bad example. All the colour TV stardards were designed to be 'both ways compatible' That is, a colour TV had to be able to correctly display a B&W signal (this was the easy way, since the set could be designed to detect the lack of colour information (the 'colour killer' circuit) and respond accordingly). And also an unmodified B&W TV had to be able to produce a good (albeit B&W) picture from a colour signal. People with B&W TVs did not lose out when colour TV signals came along. THey could still watch them, and get pictures like they'd always got. > Should newspapers and magazines only use one color, one font, etc because Interestingly, I stoppd reading one magazine when they started prinitng in colour. The schematic diagrams printed over 'interesting' coloured backgrounds gave me a headache. I think others felt likewise, the magazine stoped being published not long afterwarrds... Of the magazines I read, the one that could most benefit from colour would be 'Clocks' (a magazine for people interested in real, mechanical timepieces). And amazingly it's the one with the fewest colour pages per issue... > Just because my PDP-8 can't video conference or interact with my whiteboard, > doesn't mean I shouldn't use them.

Maybe... If you apply the HV to the mains connector, I suspect the only thing that would fail would be the fuse (the 5151 has a linear PSU with a nice fat mains transformer at the input). If you apply it to the signal cable, well, it'll probably take out the input buffer chip (a '04 IIRC, I can't be bothered to go and get the schematics). Maybe some smoke. I doubt you'd get many interesting effects though. In any case, the monitor is not unchanged at the end, so I would class that as a modification :-) -tony

Just imagine a wireless webserver the size of a match head. :) I remember thinking at the time, 'how does this thing compare to an Apple II?' Of course the guy showing it to me didn't have the slightest idea because he didn't know what a 6502 was. So perhaps I should ask here: how would your typical 2005 vintage PIC compare to a early-1980's vintage 8-bit microprocessor? From what little I could gather the interface with the outside world is terribly limited (something like four lines on the chip I was looking at, one of which was special purpose) but that is slightly negated by the thing having an, albeit miniscule, amount of memory on chip.

Battell surplus. zero > bids, $12,500 starting bid. > Jim Davis. > I would get it, if I had free power. Despite what the seller claims, it's definately too slow to be on the top500 list. When I looked into it, I found out it was last on the list in June of 2002, and wasn't very high up (low 300s). The machine is (or was, with all of the frames, which the seller doesn't seem to have in the auction listing) only 512 processors of 120/135MHz processors. They're not horribly slow, but definately not computationally worthwhile. The ~900 processors of IBM SP (375MHz POWER3) we have at work (well, we've got 320 now, soon to add another 576) won't even make it onto the TOP500 list this next time around I'm pretty sure. As far as memory and disk space go, you'll probably be using up a good chunk of the disk space per node for OS and software; and the memory is evenly distributed between all the nodes. Having a large amount of contiguous memory and disk (like what you can with an IBM p690) is much more interesting from an HPC standpoint. :) One rack of the SP system would be sort of cool to have, but having that many frames just doesn't make any sense no matter how I try to look at it.

Please send any problems to me offlist at jwest at classiccmp.org Of course, to do this, I had to pick if I moved web or list services first. I chose list services. Any classiccmp websites I host gratis - if they have their own domain they should be ok, otherwise (they are tied to the classiccmp.org domain), they are down till I get them moved. This will likely be a longish process. I apologize for the inconvenience. I'll email again when all seems to be done. Jay

I'm getting a feeling that der Mouse is about to remind us again that one can use GhostScript instead of Acrobat Reader... The problem with GhostScript is that porting it to a Very Vintage platform will likely be more difficult than rewriting it from scratch. I once thought about building it under 4.3BSD-Quasijarus (so I won't have to log into a Linux machine on the other side of the planet to convert PDF to PS), but one cursory look at the code was enough for me to scrap the idea. Open source is of no help when it's unusable. I have pretty much given up on using any software not written from scratch by me. It's almost always easier to write the program I need than to port an existing one. MS
