I'd love to write a program to "OCR" punched card images. Now, if I only had some spare time. :-) Scanners are cheap and ubiquitous. You could lay several cards on the scanner at once, perhaps placing a specially-colored paper on the normally white reflective lid, and presto - like chroma-key on video, you can easily "see" the borders, index notch and holes. I wonder if any of today's "paper port" auto-feeding cheapo scanners would handle a punched card - I don't see why not. It could save the card data in Jone's proposed file format. One advantage of this system would be that it could handle aged cards that some physical imperfection (like dents from rubber bands, folds, worn edges, etc.) that might jam a card reader. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

Help - Sun 2 won't boot

by pjoules＠enterprise.net

I have just got a Sun 2 clone workststion (Sun boards in an unbranded box) and it won't boot. If any one can decode the 'heartbeat' LEDs here is the code. Looking down at the edge of the CPU board: =============[Empty connector]=========[oxxx ooox]==================== where x is LED off and o is LED on. I would like to mend this myself if possible. If it is going to require component level diagnosis and repair then please bear in mind that I haven't used a soldering iron or meter in anger since I was mending televisions at school - when they all had 405 lines on the screen and valves.

I rather liked Allison's long array of photodetectors (of whatever flavour) to tell you where the leading edge is. But why not have the same wheel to determine the position, but the card turns the wheel rather than vice versa? You lose the non-contact element of hand pulling, but you don't get motors chewing delicate cards. Philip.

This sounds like a homework question... Well, I suppose all classic computers have adders in them. You want to look up "half-adder" and "full-adder". A half-adder adds two binary digits, to produce a sum output and a carry output. A full adder is, not surprisingly, two half adders, wired so that it also has a carry-in. You can make a half-adder from an XOR gate and an AND gate, though that's not exactly how they're usually implemented. How to make a multi-bit adder with look-ahead carry is left as an exercise for the reader :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

Sun boxes are around (Sparc), I even saw DECstations, RS6000's but no good looking Vaxes or 11's. I think the area scrapped most of 'em 4 years ago. At this weekend's Trenton Fair (which used to have 8's, 11's and Vaxes -- nothing below a Microvax chassis...). And this was a big DEC area until the late 80's.

Neural nets (OT)

by maxeskin＠hotmail.com

I made a small neural net, non-learning, in Visual Basic (hey! it's easy!), available at alt.ne.mediaone.net/zeus334/neural.zip. Also, there was just a short segment on TLC on truck collecting. Very interesting. Maybe I'll collect old trucks AND old computers! This was talking about a new englander who collected big trucks.

This is the case for the april early birds from what I saw last year. As the season progresses (MIT is every month) the mix changes. < He also had an 11/23 he wanted to sell for $100 and _wouldn't_ < budge. He told me they were 'classic' computers and could If it were an 11/20 or 11/05 it's collectable. Numb is correct. 11/23s are common as house flies and though they are very classic and somewhat desireable for pdp-11 hackers he's out of his mind. Last year there was someone there doing same and I ended up taking it home for free as he couldn't bring it back. Now consider this he was offering an 11/23 complete with RX02 and 2meg memory, plenty of serial IO and TWO complete copies of RT-11v5, two sets of diagnostics disks and two RT11 doc sets. If he parted it out and sold it to one of the used DEC resellers he might get 100$ for the peices total. <PS - I would have paid up to ~$20 for the 11/23, but $100????? thats about right IF it's at least a complete CPU/mem/io/disk! With some software and known operating $50 may not be out of line. more than that it better be pristine, FULL COMPLETE DOCS and actually running. Allison

It's something I've been going to study up on tho. I've had an old Phillips Micom WP for some time which apparently was capable of communication protcols interfacing and I've wanted to retrieve some data on it , altho now I might be able to pull it off the 8'' disks with the TRS mod ll . Another project in waiting : ^ )). In exploring the programs on the 5150's Hard-card I found two small programs >from the same company (PLUS) that made the hardcard. One was light.com and the other sound.com parameters were light= on/ off , and sound = on / off . Since the h-c itself had no external connectors, I'm wondering whether these are for the cassette port. This 5150 was also configured for 2 serial and 2 parallel which would square with the serial / para on the int.modem and the printer port on the Herc. leaving one serial unaccounted for. The only other connector is the f 37 pin ext. on the fdd controller card. ( for an external drive ? ) QUE's Upgrading and Repairing P.C.'s v.5 (BTW an excellent book with the most extensive info on PS2 s I've seen -V.5 only) doesn't mention this port tho it has a lot of detail on the 5150 and adapter cards. ciao larry lwalker(a)interlog.com

Strange 11/83 behaviour...

by DSEAGRAV＠toad.xkl.com

This is bizarre... This RSX was origionally in an 11/73. I had it in an 11/83. BOO was running REAL slow. I interrupted it after a 5-hour run. I swapped the KDJ11-B with an 11-A, reloaded, and now BOO is running at a faster pace, it hits the drive every 10 seconds. I just now started it. Maybe there's a bug in RSX, or my 83 is acting bizarre? -------

I think that means you're trying to do something to a disk that is mounted when it shouldn't be, or you've not given the right switch, or given one that's inappropriate. If I'm right, I think you want to be copying from a mounted running DUx: to an unmounted but loaded DL0:, which BRU will want to re-initialise. If so, the command is something like BRU DU0:/MOU DL0:/INI, or safer would be to run BRU and enter the disk names and switches at the prompts.

MIT flea

by maxeskin＠hotmail.com

This is the first time I've been to an electronics flea market, so I don't know how it was, but I was disappointed. I came late, and about 1/2 the stuff was oscilloscopes, another 1/4 was Mac CPUs, and an 8th was PC network cards. Everything was priced at or above market value (almost). I will still go next time, though. There were a bunch of "IBM RT" units. These were enormous PS/2 like things. What were they? I could have gotten a Zenith XT laptop for $10, but I opted for a free Data General One being used as a wheelchock. It's in good condition, but the LCD is smashed. I think I will hang it on the wall. Does anyone have any ideas what I should do with the rest of the machine? Does anyone have replacement LCDs? PS. I would have gotten a shrinkwrapped copy of MacOS 6.0.7 and A/UX, but the guy changed his mind about selling it. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Test Equip FS

by rhblake＠bbtel.com

Ive had this posted in the past but these are really getting in my way: *Tektronix 7612D programmable digitizer (scope w/o a screen) with two 7A16A plugins. No manuals or cables but it appears to be in terrific shape otherwise. $150 plus shipping or will consider trades. *Kontron KLA64 64 channel logic analyser - 2 complete units, cables, manuals, covers, software, etc. They also have an optional unit installed internally. Includes Axiom video printer. All items go as a package - $325 plus shipping. Sorry no trades and will not separate. Total weight about 160 lbs for everything. Can email detailed info to those interested. I bought these in an auction lot and the above pricing is what I have into them. I bought the auction lot to primarily obtain a digital oscilloscope for my shop but the above items are R&D oriented and realy have no use in my repair shop. Both are still supported by repair, calibration and parts outfits as well as the manufacturers. I have sources for the manual for the Tek 7612D and plugins as well so you don't need to be concerrned that you'll not be able to work it without a manual. The manuals for the Kontrons is very detailed and is from setup and use to parts and adjustment. I'm trying to be as discrete as possible about posting these and I'm sure some people are tired of seeing it come back up but there are new people to the list that may not know of them and possibly be interested. Please reply direct to me, not to the list. -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Not necessarily. SYSGEN recreates the whole system from the source code. All you need to do (assuming the original was built with suitable options) is to get it to reset its pointers, in a manner of speaking. You won't have HRC unless it's an RSX11M-plus system. > That would be why BOO looped forever on both systems, the monitor was told to > boot a device it had no support for. > Does this sound correct? I don't think so. I'm not an expert on RSX, but I've done 4 or 5 sysgens -- though it was a few years ago. The drivers were probably all built at the same time -- and therefore with the same options -- as the rest of the system. Take a look at the dates/times on the xxDRV.TSK and RSX11M.TSK files in [1,54] to be sure. The RSX11M.SYS file should be much bigger, and have a later time, than the RSX11M.TSK file. What you're probably seeing, is that the system was built with a certain amount of space allocated for drivers, but only the ones originally required are loaded with the system image by default, and to get space for another, you need to unload one. As for the BOOt problem, I'd guess you copied the files using PIP instead of BRU. Is that right? If so, many of the files won't be in the same places on the disk. That will confuse RSX, which has the disk addresses of some essential things in the RSX11M.SYS file. (At least, I think it's that file, it's been a while...) Also, PIP has possibly not copied the correct file size -- by default, it discards unused blocks, ISTR. That will kill RSX11M.SYS, which has extra blocks for the swap space. The other thing PIP won't do (by default, unless you use the /CO switch) is to ensure that copies are contiguous, though if you copied onto an empty disk, that probably won't be a problem. You can tell if a file is contiguous (all the blocks together, in sequence) by looking to see if there's a letter 'C' just before the date in a long directory listing; .TSK and .SYS files have to be contiguous. If you copy with BRU, it takes care of those things, and possibly leaves the system in such a state that the next *software* boot will sort things out. There are certain permutations of disk drivers that share boot blocks, which saves you some of the effort of re-generating the boot setup, but I can't remember if DU and DL are in that group. [digs out notes] If you use PIP, you'll need to recreate the RSX11M.SYS image on the new drive, while still running the system from the old one: ASN DL0:=SY: ASN DL0:=LB: SET /UIC=[1,54] PIP RSX11M.sys/NV/CO/BL:<nnn>=RSX11M.TSK where <nnn> is usually (memory size x 4) + 2. If you express that as a decimal number, you have to enter it with a decimal point after the digits otherwise PIP will think you mean octal. That's for a mapped system; change [1,54] to [1,50] for unmapped. Then you'll need to re-VMR the system, you can specify what drivers are to be LOAded at boot time, what memory it has, etc. There's possibly a file called SYSVMR.CMD or similar, which already has a string of commands in it to load drivers; edit that to suit. After you've run VMR @SYSVMR you need to software boot the new system and SAVe it (you may need to type "G" at the prompt, and you need to SAV /WB to make it hardware bootable). -- Pete Peter Turnbull Dept. of Computer Science University of York

Since I'm switching boot devices to one not in the monitor, I have to re-SYSGEN RSX-11M. But, I don't have Sysgen or HRC, so I'm screwed, right? That would be why BOO looped forever on both systems, the monitor was told to boot a device it had no support for. Does this sound correct? -------

Week-end finds

by fauradon＠pclink.com

Hi, I found an Epson HC-41 today, it was aparently used for a machine tool programmer. Does anyone have a keyboard overlay that I could copy to replace the custom overlay that they have on this machine? Also i got the Floppy drive with it with instructions in Japanese. Can anyone give some info on it? I am also missing both power supplies (yes they work from the battery) what are the reqirements? As a general request, any info on that machine is welcome. I also got another Fairchild channel F brand new and apparently never used. And a Laser 128 with power supply and external disk drive. Oh and a copy of the Haddock.

Very cool book find

by dastar＠wco.com

Now this is maybe a book that's worth $153. Electronic Analog Computers (Second Edition, Hardcover) Subtitle: D-c Analog Computers Granino A. Korn, Ph.D. and Theresa M. Korn, M.S. McGraw-Hill Book Company, 1956 (Original copyright 1952) The lower-case 'c' is actually how its used in the book and the subtitle. Here's the first couple paragraphs from the preface of the book: D-c analog computers are relatively simple electronic devices now commonly in use to solve a variety of problems in applied mathematics and engineering design. The application of such computers to the simulation of modern automatic control systems has been particularly successful; but some acquaintance with d-c analog techniques can benefit almost any engineer or research worker, no matter what his special field may be. A d-c analog representation of a problem does not merely furnish needed numerical data. It often seves as a working model which helps to close the gap between physical intuition and exact analysis. The continuing remarkable progress in the related fields of electronic computers, instruments, and controls has led naturally to the preparation of a new, completely revised edition of _Electronic Analog Computers_. The greater part of the book has been entirely rewritten. We have attempted to carry out our original purposes, namely 1. To acquaint research and development workers with tried methods for the application of d-c analog computers as computing aids and simulators, and with the possibilities and limitations of such equipment; 2. To present a comprehensive body of up-to-date design information on computer components and systems. We believe that such information is of particlar interest to scientists and engineers engaged in the development of instruments and industrial control devices. *** There are also pictures and descriptions in here of computers that I have never even heard of, such as the Curtiss-Wright analog computer (CURTIAC); the Berkeley EASE (Electronic Analog and Simulation Equipment) computer made by the Berkeley Division of Beckman Instruments, Inc.; the Electronic Associates Precision Analog Computing Equipment (PACE); the Goodyear Electronic Differential Analyzer (GEDA) made by Goodyear Aircraft Corporation; and the Reeves Electronic Analog Computer (REAC) made by Reeves Instrument Corporation, New York City. Also: [A picture of a Donner Scientific analog computer] A complete table-top d-c analog computer priced just below $1,000. The unit comprises ten operational amplifiers, power supplies, all necessary controls, and a removable problem board. Multipliers and function generators are available as accessories (Donner Scientific Co.). [A picture of a Heath analog computer] This complete 15-amplifier machine is available as a do-it-yourself kit for less than $1,000. The amplifier tubes are top-mounted to minimize heating of components. The 30 coefficient-setting potentiometers are set by comparison with a built-in precision voltage divider which is also available for gain measurements (Heath Co.). Wow. The book is in excellent shape, save for the damn price written in grease pencil on the inside cover thanks to the stupid thrift store pricer.

IBM Executary

by TOwad＠aol.com

Can anybody tell me what an IBM Executary is? To describe it briefly (I didn't have much time to look at it), it is a small box, blue on the bottom with a dial on the front, a few knobs/switches here and there, and a very large hole in the side. Connected to it is a pedal of sorts. Push on the right and it clicks, same with the left. Can anybody tell me what it is? Is it worth $6? Thanks, Tom

I have one of these units in my collection, and even though it happily accepts the commands which should read punched cards, it always feeds one card and then returns an error.

How do I tell RSX11-M to make a RL02 bootable?

by DSEAGRAV＠toad.xkl.com

Moving RSX from that RDwhatever that's making bearing noises to a RL02. Copied all the data files and such to the RL, but the RL isn't bootable. When I try booting it types ** THIS IS NOT A HARDWAREBOOTABLE VOLUME ** or something along those lines. This is RSX11-M v4.1 It's a severely butchered configuration made for a graphics workstation by Genigraphics, that I hope to try making useful. If the command required doesn't exist, (Likely!) I cam reload RT-11 and kermit the RL up to a PC, put a bootblock on the front, download it again, and go. Does that sound do-able? -------

C128D Manual needed

Apple drive for Diamond TrackStar

Hello, all: I just got myself a Diamond TrackStar Apple//-in-a-PC board. What little info that I could find says that you can hook an Apple floppy drive to it. However, in two places, the info says that it takes a standard Apple floppy, and then it says a Unidrive. Has anyone used this board? Which drive would it use? I know that it has a 20-pin header on the board for the floppy. Any clues?? Rich Cini/WUGNET <nospam_rcini(a)msn.com> (remove nospam_ to use) ClubWin!

Zinith ZWL 183-93 "Laptop"

by foxvideo＠wincom.net

Turned up one of these on Friday. It has a 21 meg HD, an 8088, and is about like having a flat bed scanner on your lap! No power supply and battery pack (10 size "D" nicads) shot, but got it working off my bench power supply. It appears to be working normally and I think I can rig up a power supply from a Sony version for a portable VTR. Is anyone familiar with this beast? It must be one of the earliest laptops. I also got three C-64's in the '128 style cases, but didn't get into them yet. Regards Charlie Fox

Warez?? Was: Re: James Willings still up?

by photze＠batelco.com.bh

Yes, indeed, Warez people are the 3rd generation hackers. For the most part, they're not to good at all. They pretty much just take software and pirate it (hence the name "warez" pronounced "wares") They can hack NT (like someone can't!) And for the most part, think that UNIX is dead. They couldn't tell you the differance between a modem and a sound card, except "one has the phone jack". They don't do good, or even do anything that no one's done before. They just go in, say that they've "hacked" a website, and brag about it in a chat room for the next 50 hours. They're mostly teens, and techies-gone-bad. Tim D.

I got a July '87 copy of a computer catalog, and it had a product which I found pretty interesting. This was a small modem-sized box that went between the keyboard and the computer. It was a hardware spell-checker, powered off the keyboard, costing $20. It was supposed to beep upon detecting a mistake. Seems like a good idea.

Once the drive is sitting on the rails squarely it is _fairly_ stable and can be juggled about to line up the screw holes.

How Do You Program Nintendo Games?

Non-classic but still interesting

by maxeskin＠hotmail.com

A few weeks ago, I was charged with fixing a new Macintosh 5400/180. It had been in a music room, in a sound proof booth, for several months, with a MIDI interface being used for music software and the like. The problem was something with the hard drive. This is the second hard drive failure I've seen since an AT&T 6300. When the drive tries to seek, it sound like a pendulum is stopping (tick... tock,tock,tock,SILENCE). The head never sounds like it moves. The little LED on the drive flashes, though. This is an IDE, by the way. So, here's the good part. We sent in for a replacement, and in a few days, it's the same way. Now, I'm thinking it's a problem with the sound box's power supply, maybe those 2GW speakers in there. Any ideas before we fry another 8GB? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Furnished with the highest end computer hacking equipment by the US Government, under the direction of Oliver North, they went rogue when the program was discontinued during the Iran-Contra scandal. After their payroll was cut, the village, ironically, hired itself out to international terrorist concerns to perform paid attacks on US commerce. This situation was exacerbated by an abortive attempt to invade Warez by Puerto Rican commandos under the direction of the US military in 1997.

How Do You Program Nintendo Games?

by dcoward＠pressstart.com

Tim D. Hotze said: >Well? How DO you program Nintendo games. Do you need to compile? >Or is it more like BASIC? Is it done in any specific language? > Just asking... The NES (unless I still half asleep) executes 6502 code. The Super NES is 65816. I think the GameBoy is Z80 (I've never programmed on it). And the N64 uses a 4000 series MIPS processor (4300 or 4400 I'm not sure)(I've never programmed it either). You could write code in 'C' if you have a cross compiler. On the N64, I'll bet that most of the programming is done in 'C' (maybe 99%) because there you are using Libraries that handle all of the low level stuff. ========================================= Doug Coward dcoward(a)pressstart.com Senior Software Engineer Press Start Inc.

Wang Computer

by lwalker＠mail.interlog.com

My most recent discard find is a Wang PC-S3-2 . It had had 2 winchester disks removed before being thrown out, but otherwise seems intact. No KB , monitor , or FDD's of course. From what I've been able to find on the net ( Wang CUG) it's an early "Classic PC" but this predates their oldest listed model specs. There seems to be many more sites on the CPM models but not on Wang PC's. The full-size motherboard has Z-80 and 8086 chips and 2 20 pinM ribbon connecters below two cutouts leading to the HD enclosure ,a centronics parallell printer, 25 pin serial, and KB ports on the rear. It has 5 half-size expansion slots .all occupied. One card is labelled PM 101 IBM Mono emulation and has 2 rear sockets. One is a regular 5pin kb socket and the other an 8pin din which I imagine is the monitor port. Strangely enough the same din as my Epson KB. This board is coupled with another by a 10 line ribbon cable. On either side of these are 2 cards that look identical the bottom-most labelled PM 021 / 022B Winchester Controller. Both have 20 pin and 10 pin male ribbon connectors. The top-most card looks like a memory card and has a LED. It's somewhat sparsely populated with mcm 6665 (motorola mem ?) and low-powered schotsky chips but traces for many more sockets. Seems pretty straight forward if it wasn't for the extra 20 pin connectors on the HD controller cards. Fdd connectors ? My lack of technical knowledge is showing. Maybe because of the company I'm keeping on this techno-whiz m-list. It's intimidating. :^) I believe Wang had it's own proprietory system and I did d-l a set-up from the Wang CUG site but info on this beast seems scarce, tho IIRC they were widely used in business operations. Anyone ?? ciao larry lwalker(a)interlog.com

Those only exposed to western design philosophy tend to belittle soviet engineers because of the seemingly crude appearance of their equipment, but they had to meet vastly different product requirements. Their export market was the underdeveloped third world, no infrastructure at all. When your target market is some place like Mongolia, Eritrea or South Yemen you have an entirely different set of design parameters. There is no Radio Shack down the corner, no parts store in town, no UPS delivery service. Even literacy is at a premium. Yet they were able to deliver relatively sophisticated equipment to places like this, and were able to maintain it locally. I for one have a great respect for soviet engineers like Mikoyan or Antonov, even Mikhail Kalashnikov, the guy who designed so well he worked himself right out of a job. Jack Peacock

When we fell heir to the big heap of Apple stuff outside Sacramento, one of the things we found when we dug in a bit was a Soviet Apple ][ clone called an Elektronika. I can't quote chapter and verse because we haven't really unbuttoned it yet, but it would seem that the really astounding part isn't the computer, it's the monitor. We also have schematics and, when I have a bit more (i. e. nonzero) free time, I'm going to ferret out someone who can read them. Max would probably be a good start! Also, for a source on this, remember that in _TCJ_ a guy named Helmut Jungkunz wrote a bunch of columns about both Soviet and East German computers. __________________________________________ Kip Crosby engine(a)chac.org http://www.chac.org/index.html Computer History Association of California

I remember last summer, there was something in CNN about Berkley (or one of those California universities that you'd associate with computers/technology) Developing a blue laser. This could radically change everything, including DVD. Ciao, Tim D. Hotze

That's my biggest complaint about the Soviets. They gave communism a bad name. The USSR, in my opinion, wasn't a true communism any more than Rome was a democracy after they had "dictators for life." Nice try, but a true communism would be the opposite. Everyone would have everything, if humans worked on an equal basis. That's why communisms don't work with people: They'res a few rotten apples in every barrell. Also, look at Soviet technology and people as a whole. Even though MiG's did use vaccum tubes, they were still considered a threat, when equipped with Soviet pilots. As for the technology, I'll say that it wasn't behind the US, but rather on a path that we didn't follow, and so it looked like they were behind us. BTW, I'm guessing that with a $20,000 A2 clone, the avreage Dmitri didn't get one in the USSR. Tim D. Hotze

There was a big sign on the wall that said "Turn the computers off before leaving!". That wasn't meant for us, but I didn't know that, and I once turned a terminal off. I came back next time, the terminal didn't. I guess it had volatile ROM or something. In general, I liked those terminals. They looked very, um, handmade. >went on.

> Hotze wrote: > Yeah, that's why all the newest Soviet fighters and bombers > used vacuum tubes > even into the early 1990's. I'm sure they invented this and Not so fast, there are very good reasons to use tubes instead of solid state on certain types of military electronics. Look up "EMP" sometime. This was a deliberate design decision on the part of soviet avionics designers. They do have workable solid state devices. In fact, the later Sukhoi and MiG models had very sophisticated interlocking radars at the squadron level, a capability US forces do not have. Yes, overall the US made much better avionics and electronics in general, but when it was important enough the soviets could produce very good military equipment. Off topic, but I much prefer Russian assault rifles to US ones. I keep an AK47 at home, I would not trust an M16. I wouldn't care to run a business with a Russian built computer though...

The PC's Soviet?

by allisonp＠world.std.com

<What's wrong with vacuum tubes? You're the ones collecting them :0 In their time it was the best technology. But the answer to the question is, too big, fragile, High power needs, lots of heat and they make lousy high speed switches (IE binary elements). As to EMP immunity, not much use if the memory is wiped and less help if the system is so slow and awkward that reboots are impractical. Vacuum tubes offer little help there. As far as I know the Soviet Russins had technology but they were limited in their ability to translate that to volume product. That combined with no production capability that wasn't allocated to the military was a mess. It wasn't for lack of bright people just a messed up system. Allison
