See previous discussions of this on the list. It is on the order of 10000 DPI. I have two fiche scanners, A 3M unit that I actually have software for, but requires manual positioning and a much older automatic unit with no docs or software. The effective resolution of the output is normally between 200 and 400 DPI after magnification between 20 and 30x.

Hi I believe this is normal. According to the schematic I have, only the motor is switched. The transformer that supplies the current loop is still active.

reforming PS caps w/primary-side components

Hi I think the rule is 0.5ma per cubic inch of computer grade capacitor and 0.25 ma per cubic inch of normal capacitor. As an example: 2" dia X 3 inch = 9.4 in^3 Cap voltage rating of 10V use 2.2K limiting resistor and 10V supply. Of course, if the capacitor is on a 5V rail, you'll need to disconnect one end.

HP 80 Series software

by peterbrown10＠hotmail.com

Hi Joe, >I'd like get a copy if you have it. I'm running into a couple of >oddities when I try to operate it. It's working but not the way that I >expected and I don't know if I'm doing something wrong or what. I remember being slightly confused by the operation of the bus analyser too. It didn't really seem to make sense to me for some operations - I was never sure if it was broken or that was just the way it worked. I think that these things tend to be a little flaky / sensitive - I ended up constructing a single analyser that sort of worked from three analysers that didn't. >Steve Robertson ran into the same problem when he tried to use it to >study the disk operation as part of writing an OS for the HP 1000. He did >get some usefull info but only 32 bytes of it! That's right, the internal memory buffer in the bus analyser is only 32 bytes. You can either set it up to store 32 bytes from the bus or (I think), if you have the patience, you can manually (in binary) store 32 bytes in the memory and then have the analyser clock them out onto the bus. >I'm currently investigating another option. >NI make a GPIB+ card (ISA or PCI) that acts as both a GPIB controller and a >... >codes. I'll let you know how I get on. I've now had a chance to take a look at the NI GPIB+ cards in some detail. With the proviso that these cards only work under Windows 98 se or earlier and windows NT, they seem to be an excellent solution to seeing what is going on on an HPIB bus. The software can be set up to monitor all events on the HPIB bus, control lines, data lines, control words, data words etc. The card can also be set up to passively monitor the bus and add time stamps to the captured bus events. The only limitation to the number of events that can be stored in a capture file appears to be how much memory/disk space the capture machine has. The capture files can be exported in a text format and dumped into Word / Excel for further processing. >I have (had?) a card like that but NI no longer supports it and I >haven't been able to find any docs or software for it. If the card is a GPIB+ Controller/Analyser then the software is available for NT / Win98 - you need version 1.7 of the GPIB controller software from the NI website. >I have something else that might be usefull.

For me, after looking at the GPIB+ card it seems to be a 100% solution - I am very impressed with it - only the slightly ageing software lets it down.

Bill, (1) Don't use a light bulb - they have a very low resistance when cold, and will cause the inrush you're trying to avoid. The best recommendation I've seen is to use a "variac"-type variable transformer to reduce the powerline going in. Start at minimum, and turn things up slowwwwly, watching current draw.

Actually, with a meter across the capacitor supply, stop at about one volt, so any semiconductors in line can't get terribly excited: if there's no apparent short as things stabilize, turn the voltage up. (2) CRTs aren't a hazard from undervoltage (I ran a sick Zenith TV on 85VAC for years using a Variac). It's overvoltage that causes X-Ray risks.

Display of first networked personal computer game returning

I guess that's me! I am quite busy. In a few months (3) I have my own "PDP-11 garden house" (3,5 x 8 meters) just for PDP-11's. Then www.pdp-11.nl will see some new info. On http://home.hetnet.nl/~tshaj is a link to www.pdp-11.nl and to my StarShip project. Again, in a few months time, I will start new developments ... indeed time is a problem. The 'StarShip Simulation' of Dilithium Press is the Bible, but, as it should, use it for inspiration and do not follow it like a fanatic :-) - Henk. BTW.

The PDT-11/150 was reportedly available with one or two RX01 drives, and three serial ports with another three optional. I've only seen the one I own, which has both drives and six ports.

FA-PDT-11/150 on eBay

by stuart＠stuartsjohnsonfamily.net

I noticed this on eBay and thought I'd post it here for those PDP-11 collectors among us: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2733136922&category=1247 The starting price ($199 US) seems high, but these are pretty hard to find. One possibly sour note though - the seller wants a flat rate of $150 to ship anywhere in North America. I picked up one of these in terrific condition last December for $25. It cost $65 to pack and ship the heavy thing, but it was worth it. I haven't seen another PDT sell since then. Stuart Johnson

Jupiter Computer (No Not the ACE)

by Paul.HILLS＠uk.landisgyr.com

Sorry, I can't help you with your identification, but must point out that it can't be MUCH earlier than the Jupiter Ace, since both the Ace and the MC68010 processor were released in 1983, so the computer you have can be at most a few months earlier, and probably more recent since the Jupiter Ace ran for a shorter time than the 68010! Some CAD stations have multiple joysticks, also video editing consoles, or even studio music production equipment. Could it be something like that? Is there any clue from the location you found it (on the kerbside outside what building???). You may get more clues if you switch it on and see what comes up on the monitor! Good luck paul -----Original Message----- From: peter tremewen [mailto:ptremewe@bigpond.net.au] Sent: 01 June 2003 22:18 To: cctalk(a)classiccmp.org Subject: Jupiter Computer (No Not the ACE) Hi all, I have in my hands a "Jupiter" computer and am wondering if you can offer any info on it? It is not the Jupiter ACE home computer, but a much earlier very large and obviously fairly old rack mounted system. The computer is based on the 68010 CPU. I can't determine how much memory it has on board, but there are more than several banks of 4164 mem chips which if I remember is a 64kbit dynamic Ram device. The huge keyboard is attached via a missing multipair cable and has two joysticks on either side. The monitor has separate RGB and Sync cables, each of which are generated using separate discrete component boards in the chassis. Inside the chassis are two huge Vertex hard drives, and a 3.5 in floppy, each connected to their discrete driver boards, Z80 based. On the front of the computer is "Jupiter". Model number is J12CHAS and Man date is "514". It was manufactured in Berkeley C.A. USA. The serial number is "Jup.S.N. 12C-1025-AA". I basically found it all on a curbside and couldn't resist adding it too my rather small but now growing collection. If you need any further info to help with identification let me know, I'll see what I more I can get from the chassis. Maybe I'm insane and have just picked up what most would consider total junk, but I personally think that systems such as this are worth preserving. I haven't been brave enough to switch the damn thing on yet, with all that discrete hardware it will probably double my power bill with about a minutes use. However I love all this old stuff, and worse comes to worse at least their are some interesting discrete components in it. If you need or would like a photo let me know, I'm a freelance photographer and will take a few shots anyway, so when I do I'll pass some scans on to you. Peter T.

Where have all the Selectrics gone?

by jontitus＠attbi.com

My Selectric III went in the local metal-recycle bin quite a few years ago. It was getting sticky and needed a thorough cleaning. The local IBM service center wanted $125 just to take a look at it, so enough was enough. I have not used a typewriter in the last 8 or so years, and don't miss it. I had a second Selectric my brother gave me, but during a move, one of the cast-metal parts gave up the ghost. It seemed too expensive to get it replaced, so it, too, went to the metal recycle bin. I suspect many other typewriters, Selectrics et al., met the same fate. My mother, 89, still uses a manual typewriter, but her sight is failing and she has a hard time getting the right roy of keys. Sometimes we have to sit at the keyboard and "decipher" her notes. She recently found a typewriter repair shop on Long Island (NY) that would repair and clean her manual unit. She got new type and a cleaned unit for about $85. That's a deal.

Teletype

Whenever I type anything I just get a left-arrow. I am blaming the 1818-23/-21 for this. Shouldn't I? OK; current loop. Would this explain a resistor (14 Ohm, big) in the slot of the KSR would get extremely hot when off this loop? Also; Hans Pufal, I would be most grateful for the schematics for the CL>RS232 converter. Also tell me more about the modifications made to the TTY control on the PDP? The card says 181823 on the solder side and 181821 on the other. Thanks! -Tore "Life's a bitch and then you turn on your PDP and it's all nice and when you turn it off it goes back to being a bitch.

Curt Vendel needs RK05 drive on east coast

by aek＠spies.com

Knowing Atari, there tapes were most definitely written on a PDP-11 system. == They are discs, not tapes. Atari switched from development on PDP-11's (an 11/60 that actually was at Weird Stuff when they were next door..) to a VAX in the early 80's. They are probably the RM05 packs from KIM:: -- I don't know about you, but I would be pretty surprised if Curt is going to find someone willing to put an unknown 12 platter pack in their RM05. I dont think Scopus or any of the disc inspection companies are even around any more. I have several dozen of those same vintage packs that I'm terrified to even try to put in a drive (not for a VAX..)

Then the records can either be entered by one/one group of people. Or people can self-register their computers, pictures, etc. Problem with having one person do it: time and money. Problem with self-registration : how to motivate collectors to register their stuff? Why bother? The one Internet tool that I've seen that really has people using, strategizing, and making complete registrations on is eBay. Sellers are motivated to have their things well-placed and carefully indexed so that they can be found by prospective buyers. Well, that's not entirely true. Computer collector websites are often very very cool; full of photos, scanned documents, lists of possessions, tips, stories, and other exotica. And to find those, I don't need a database, I need Google.

HP 80 Series Software

Hi All, > Yes a FEW of the HP-IB hard drives. The only drives that would work >without specail support were the HP 9133/9134 that had a apecial option >that made the disk look like three HP 9895 8" floppy dirves. There is a...

I haven't had time to set up a machine with the HP-IB card >and install your SW. Let me know when you get things going, the software has gone through a number of revisions since the version I sent you. I'm now looking at an application that first strips all the data from an HPIB disk drive dumping it onto a PC. A second application on the PC then emulates an HPIB drive using groups of files stored in a simple directory system on the PC. >I've been spending a lot of time with the HP 1000s and >with a HP-IB interfaced Speech Synthesizer that I found. (It's COOL!) Sounds like a pretty rare piece of kit - is it a commercial Speech Synthesizer or home-brew? >That's taken me deeper into the HP-IB bus operation and I've had to repair >a couple of HP 59401 HP-IB Bus Analyzers for use with that. (Anybody got a >manual for these?) I certainly have an operations manual, it may include some service bits and pieces. I'll take a look when I get home to the UK. I have a couple of these bus analysers at home, I used them in the initial investigations for the CS80 reader. You can use them to slow down the bus traffic on an HPIB system either to 2 transactions a second or single step. I tried using one to investigate the traffic between a 9000 300 machine and a disk drive but as soon as you slow the bus down the 300 series machine complains that the disk has timess out. Luckily I have an old HP 3562 spectrum analyser than interfaces to CS80 / AMIGO disks. You can single step though commands with no timeout problems using it as the disk controller. In the end though useful the 59401 is somewhat limited in what it can do. With the long command sequences that I was examining I ended up having to write down each octal (Yes, OCTAL - the I lost count of the number of times that I accidentally read the numbers as hex....) data packet as it appeared on the bus and then go back and try to decode what it all meant. The bus analyser also occasionally dropped the first byte of information being sent back by the HPIB disk drive. I'm currently investigating another option. NI make a GPIB+ card (ISA or PCI) that acts as both a GPIB controller and a GPIB analyser. In theory this can be set up to 'sniff' the GPIB bus and generate a log file of each GPIB bus event (with a 50 ns time resolution). The log can be as long as you want so no more laboriously copying down octal codes. I'll let you know how I get on. > I'm still looking for those blankity-blank manuals! Don't know where I >put them. I found a set of paper back manauls of the same thing. I don't need the manuals straight away. I'm hoping they contain some info about HP-UX file formats (and general HP-UX stuff - I have no experience with HP-UX systems) >Did the other manuals arrive yet?

Where have all the Selectrics gone?

by mross666＠hotmail.com

IBM made a bunch of printer terminals based around the Selectric typewriter - 1052, 2740, 2970 etc. Look in any old copy of BYTE, and you'll also find several vendors were selling 3rd party terminals based around IBM Selectrics, often converted for ASCII/RS-232c operation, as teletype alternatives. Where have they all gone? (I appreciate, from what I've heard, that many folks who used them in anger would reply 'I don't know, I don't care, good riddance!') Early DECwriters are not uncommon. Teletypes are (almost) ten a penny, ASR33s show up frequently enough on ebay, I have several. But the only Selectric based unit I've *seen* in over ten years of collecting is a 2970 Reservation Termainal (see http://www.corestore.org/2970-1.jpg ) which I was offered a year or so ago. It needs a fair bit of TLC, and it's a print-only device; it can receive data from a host and print it, but not send anything back from the keyboard. I'd love to get a bidirectional equivalent to use as an 'authentic' terminal for a 360 emulator I work with... any clues? Can anyone recommend a Selectric repair shop? No way I want to try to fettle something THIS mechanically-intimidating myself! Mike http://www.corestore.org

Display of first networked personal computer game returning

by alhartman＠yahoo.com

Oh Man!!! I thought I was the only one who remembered this book fondly! I used to have this book and pour through it. Wishing I had the money to build a replica of the Enterprise bridge and make each station a Computer like this book outlined. Alas, I've lost my copy of this book. I hope I can find another some day... (Can you send me ISBN Information?) Thanks for the title and author, that should help a lot... I think something like this would make a WONDERFUL type of attraction. Where people would pay to spend a day in the Simulator and go "Exploring". What's missing in a lot of the Computer Games today, is just the fun of exploring... Not just blowing up Borg or Klingons and the like... Like Starflight I or II... Even Escape Velocity on the Mac is fun, because you don't have to go battling, you can just go around trading and building up your ship...

That pesky Jupiter Ace *still* won't work...

by philpem＠dsl.pipex.com

Hi, I've just finished fixing the Ace's PCB using wire-wrap wire. All the broken tracks I've managed to find have been fixed and all the damaged through-hole plating has been repaired. Except there's one problem. The Ace *still* won't boot to the FORTH interpreter. There is a load of garbage on the display - this seems to change while the machine is running. The power consumption of the board - CPU and all - is around 800mA (according to the crappy meter on my Farnell 1A bench PSU). I've got the output on the PSU set to 9V, no current limit. Does anyone here have a logic analyser or microprocessor debugger that I could borrow for a few days? I've got two scopes (a Tek 466 and a Gould OS1100) and a Fluke 25 multimeter, but that's about it in terms of test equipment. Alternatively, does anyone know if a diagnostic ROM exists for the Ace? Something that would replace ROM A and just load the video/font RAM with the usual Ace character set would be very handy. The 2114Ls I'm using appear to be OK, but they draw a lot of current - in the region of 75 to 100mA each. Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/

Curt Vendel needs RK05 drive on east coast

by vcf＠siconic.com

Curt Vendel of the Atari Historical Society needs help. He's obtained a bunch of RM05 carthridges that apparently contain a lot of interest Atari corporate data. He'd like to read these but doesn't have the necessary gear. Is there anyone in the New York area (or thereabouts) who has an RK05 drive that they can loan to Curt so he can read these? Better yet, does anyone have a working PDP-11 system upon which these tapes can be read? Anyway, if you think you can help, please contact Curt directly at <curt(a)atarimuseum.com>.

This causes the processor to execute endless RST7's. This will make it loop through the addresses so that one can easily check out selects and such with a scope. I remember from my old days at Intel, I had an 8080 on a home made socket adapter that I could do this with. It was always the first thing I grabbed when I had a new system that wouldn't boot. It had a switch on it so that I could convert the normal PUSH of the address to be a read instead of a write. This allowed me to check data buffers in both directions as well. It seems like the switch changed the pullups to pull downs to generate NOP's instead of RST7's but it has been a long time. Just a thought. Dwight

Computer in Dark Star

Just been watching John Carpenter's film "Dark Star" (again). There's a very brief shot of a computer toggle-switch front panel. It seems to have two rows of 15 lights (neons?) and two rows of toggle switches (with plastic tips). It looks like a genuine machine, not a made-up prop, but what machine is it?

Teletype 33 wanted

by toresbe＠ifi.uio.no

Question regarding the PDP-7 (see http://www.classiccmp.org/pipermail/cctech/2003-June/015291.html) I am working on the Teletype (KSR33) and wondered if anyone has (a reasonably priced) one? ASR is a small plus, but not neseccary. I have a pathetic budget for this (?9, $12-ish) project, but I could probably scrape up some dough if needed. I live in Norway, so Europe is a plus. We have the 220v-115v converter built-in to the stand. And, does anyone know about the interface of the thing?? Is it RS-232 compatible?

Restoration of a PDP-7: Update

by toresbe＠ifi.uio.no

Hello! Thought I might bring you an update on the PDP-7. IT FRIGGIN' POWERED UP!!!! *ahem* With shaking hands (afraid the huge caps would explode all over me), on Wednesday 28th of May, I flipped the magic switch. Nothing happened. I flipped it again, and it worked. The surprise of it not catching fire was enough for me to yell without noticing it, "It WORKS, damnit!". I then proceeded to point at it and make a funny sound. Video of this will come up on http://tore.nortia.no/video when I have time to digitalize it. The rest of the day was spent testing the memory and the CPU (which mostly works). Thursday I tested the IO further, as did I on Friday. I got the paper tape punch to revolve, and feed at the command of the conveniently marked "Feed" button on the console. Now, further I/O repairs need doing, and maybe constructing an emulated Paper-Tape Reader is nessecary - - if so, I'll hook up the punch to it as well. Please see http://tore.nortia.no for continuing coverage. If you ever worked on this machine, especcialy while on DEC's side, LET ME KNOW! PLEASE; drop me a line! And yes, we do have software. Lots and lots of it in good condition. Don't know about the DECtapes though.

HP 80 Series Software

by peterbrown10＠hotmail.com

Hi all, I'm not that familiar with 80 series machines. Can they be interfaced to HPIB HDD's? Can their tapes be read on HPIB based tape drives? If so then it may be possible to read/back them up using the HPIB / LIF reader software I've been working on. With the work that I've had to do on command formats I think that I may be able to code a PC+HPIB card system that emulates CS80 or AMIGO based disk or tape drives. This would mean that the old HP system could boot from a PC emulating an HPIB drive, removing ageing disk / tape drives from the loop. Are these CS80 / AMIGO command set disks compatible with 80 series machines? Joe: I have been trying to get hold of you - How have you got on with the early version of the HPIB drive reader software that I sent you? - does it catalog your drives OK? I still need to get the postage cost on the 3 HP-UX manuals I won from you on ebay so that I can close out that transaction. Let me know and I will send you a cheque.

Jupiter Computer (No Not the ACE)

by ptremewe＠bigpond.net.au

Hi all, I have in my hands a "Jupiter" computer and am wondering if you can offer any info on it? It is not the Jupiter ACE home computer, but a much earlier very large and obviously fairly old rack mounted system. The computer is based on the 68010 CPU. I can't determine how much memory it has on board, but there are more than several banks of 4164 mem chips which if I remember is a 64kbit dynamic Ram device. The huge keyboard is attached via a missing multipair cable and has two joysticks on either side. The monitor has separate RGB and Sync cables, each of which are generated using separate discrete component boards in the chassis. Inside the chassis are two huge Vertex hard drives, and a 3.5 in floppy, each connected to their discrete driver boards, Z80 based. On the front of the computer is "Jupiter". Model number is J12CHAS and Man date is "514". It was manufactured in Berkeley C.A. USA. The serial number is "Jup.S.N. 12C-1025-AA". I basically found it all on a curbside and couldn't resist adding it too my rather small but now growing collection. If you need any further info to help with identification let me know, I'll see what I more I can get from the chassis. Maybe I'm insane and have just picked up what most would consider total junk, but I personally think that systems such as this are worth preserving. I haven't been brave enough to switch the damn thing on yet, with all that discrete hardware it will probably double my power bill with about a minutes use. However I love all this old stuff, and worse comes to worse at least their are some interesting discrete components in it. If you need or would like a photo let me know, I'm a freelance photographer and will take a few shots anyway, so when I do I'll pass some scans on to you. Peter T.

As these disks become more prevalent in the market, we may include this capability. -- end quote -- I'm thinking what this means is that you can use TCM to copy 1.44MB 3.5" media, but there's no guarantee that it will reliably copy media that are copy-protected. -Frank McConnell

DOS/Windows for Wang Professional Computer (not a PC clone)?

Recently I picked up a Wang Professional Computer. Can't find a model number on it anywhere. It 8086 based, 256KB RAM, 360KB FDD, 10MB HDD. It runs MS-DOS 2.11, but it is not PC compatible. A long time before I got this machine I found some software for it. A box of original disks all marked "Wang Professional Computer". It includes 2 versions of the integrated word processor, MS Chart, DOS3.2 and Windows 1.03. Both versions of the word processor run, ms chart bombs saying I have the wrong graphics card. Neither DOS 3.2 nor Windows 1.03 will install. DOS 3.2 just hangs the machine, Windows 1.03 bombs with an interrupt error. The disks seem to read okay. Anyone know what I'm doing wrong or have working copies? I vaugely remember seeing pictures of this machine in the Windows launch issue of Byte. Though it would be cool to have windows running on something other than a PC clone. I think I've even got a copy Balance of Power for Win 1.x around here somewhere.

Mac Net dummy Q's

by cb＠mythtech.net

> Desktop > +- Apple > +- Control Panel > +- Sharing Setup > ('Start' was selected, reboot) No need to reboot after starting File Sharing, and in fact, rebooting can cause the file sharing to be turned back off. So first step, go back into the Sharing Setup control panel, and make sure the Start button says "Stop" (if it says "Start" then click it again, and wait for file sharing to startup, the button will change to Stop when it is up and running) >Now, where is the remote drive >supposed to show up on the local system? In the remote computer's Chooser, under AppleShare. If you don't see the server there, make sure both computers' AppleTalk control panel is set to use the Printer Port, and that AppleTalk is turned on (and make sure the serial TeleNet connectors are plugged into the Printer port and not the Modem port). Also, on the TeleNet connectors, make sure there is a terminator in the unused phone jack on each. I don't remember if the ones I gave you have termination switches on the side, if they do, just make sure it is set to ON (if it is, then you don't need a terminator in the 2nd jack... I know either they have they switches or I gave you terminators... I don't think I would have been brain dead enough to give you them without a way to terminate them) -chris <http://www.mythtech.net>

Cassette Media revisited

by cb＠mythtech.net

Well... audio tapes don't work as a substitute for a D/CAS cassette. At least not with my TEAC drive. First attempt, drive takes the tape, but starts blinking the access light as soon as the drive is locked, never tries to do anything with it, software says "No Media". After a quick 2nd look at the transport, I see a small finger sensor looking for that notch. 30 seconds later with my pocket knife, my audio tape has the notch. 2nd attempt, drive sees the tape, software reports "Busy" as the drive spins the tape to the end, clacks to the end and tries to spin some more, then gives up, rewinds a bit and stops. Software reports "Hardware Error". My guess is, it is looking for some kind of end of tape marker. I tried both clear leader and leaderless tape, neither worked. I also tried a higher grade tape (Type II, 630 oersteds or whatever that word is). I don't know if the end of tape is a specific magnetic marker like a format, or what. Winding the tape to the end in a tape deck and putting back in the drive causes it to rewind the whole tape until it clacks at the end again. So it is definitly trying to rewind to the start of the tape and is simply never seeing that it is at the end. It is possible that the drive is broken, but since it is seen by Retrospect on the Mac, and gives status updates as it goes, and the transport does its thing... I tend to think the drive is fine and I just can't use an audio tape. So... does anyone know a supplier of these tapes? I haven't been able to turn up anyone that actually sells them anymore. A few people on this list offered to try to locate a spare tape for me for testing... but I'm not going to ask anyone to go thru that effort if I can't get a regular supply of tapes anyway. The drive is a TEAC MT-2ST/N50. The following appear to be compatible tapes: MaynStream 20; Teac CT500 D/CAS; Verbatim ST500; Teac CT-600H; Verbatim ST600; Maxell CS-600HD; MaynStream 60; Teac CT-600N; Maxell CS-600XD; Verbatim ST600XD; MaynStream 150. All in all, it probably isn't worth much more effort. Its only a 150 MB drive anyway. So for normal use, there isn't much I can do with it (at least not when I deal with the cost ratio of Zip disks or CD-R's). -chris <http://www.mythtech.net>

The final 'Garage' sale...

by jimw＠agora.rdrop.com

28 May, 2003 ...and then one day you wake up, and things are just not the same anymore... And so it is with the 'Computer Garage'... As of today, I am with great regret announcing the dissolution of the major part of the Computer Garage collection of classic computers and related materials. First; I will detail the method in which this will be done, and then I will detail the reasons and events that have lead up to this decision. -------------------------------------------------------------------------------- The dissollution and redistribution: With the exception of between six and ten units that have particular 'history' with me, all items in the collection will be disbursed. These items will be specified shortly. Beginning in a few days, and proceeding over the next few months as needed a 'catalog' page will be created on the 'Computer Garage' site. For each item there will be a description, a thumbnail picture when practical, an estimated shipping weight, and a date.

XENIX Distribution Disks

I have the 3.1 or 3.2 system, scriptsit, dev system, mbasic, and filePro or Profile16. How urgent are your needs? I only have them available on 5.25" disks (follow the directions on Frank Durda's site to connect up a 5.25" drive). I can probably get to copying them in mid to late June. Just remind me in a few weeks. Anyone else collect the 6000's? Kelly -----Original Message----- From: Owen Robertson [mailto:univac2@earthlink.net] Sent: Tuesday, May 27, 2003 8:13 PM To: Classic Computer Mailing List Subject: XENIX Distribution Disks Well, I found someone with a Tandy 6000 keyboard to sell and it should be on it's way to me tomorrow. Unfortunately, when it gets here, I will have nothing to use it for, as I accidentally wiped XENIX completely off my 6000's internal hard disk while trying to format a secondary *external* hard disk. I will never again assume that a program named 'hdinit' will actually ask me *which* disk to erase, nor that it will ask for *ANY* kind of confirmation before wiping the internal hard disk... So I am now in the market for some Tandy XENIX distribution disks for version 3.whatever. I don't know the exact version number of the OS that was for the 6000 specifically. Also, should anyone have the Multiuser BASIC disks, or Profile for XENIX disks, those were lost as well... I didn't have any of the original disks for anything dealing with the 6000. I'd also like to get my hands on something my system never had, whose absence was very noticeable - the XENIX Development System, which contains things like the C compiler, mail, and many other things I don't consider optional in a UNIX-based system.

IMC Portcom II

by fmc＠reanimators.org

Submitted for your amusement, something picked up today while out scrounging (really looking for non-classic bits). It's a luggable. Poking out the front: 5" CRT two half-height 5.25" floppy drives (inserted floppies have extra write protect notches cut for use as flippies) 40/80 switch modular jack (6-conductor) brightness and horizontal hold knobs Poking out the back: GAME (DE9P) RS-232C (DB25S) PRINTER ("Centronics" connector) VIDEO (RCA socket) label, handwritten s/n 1193 and checkmarks for 110V 60Hz The detached keyboard has a modular jack too. It's also bit-paired (shift-2 is '"'), in fact it mostly follows the Apple ][ layout (and has <- and -> keys), and it has what look like BASIC keywords on the fronts of many of the keys, including HTAB, VTAB, GR, HGR, and TEXT. No cable between keyboard and luggable. I'm thinking it's an Apple ][ clone of some sort. It doesn't quite power up: no video display on the internal monitor. Pulling the top cover shows the guts. The top floppy drive is a Teac FD55A. The motherboard has five slots that look like Apple ][ slots; the silkscreen on the motherboard labels them S0 S3 S4 S5 S7. Date codes on the visible ICs are 81xx and 84xx so I'm guessing 1984 at the earliest. Someone's been in here before. The 40/80 switch has a lead to a paper clip that ties it (mechanically at least) to an insulated red lead that goes from the motherboard to the display board; this red lead would appear to be the +ve supply for the display. There's also a loose metal cover over the display section; it looks like it may have been held together or insulated by tape or sticky cardboard at some time but this has been removed somewhat. Powering up with the top off makes a red LED on the motherboard light up solid, but the CRT filament doesn't glow. Anyone ever seen one of these before? -Frank McConnell

PDP-11/34A / BA11-K PSU

by jkunz＠unixag-kl.fh-kl.de

Hi. I got some more parts of that disassembled PDP-11/34A yesterday. I think I have now all PSU parts: - power inlet unit with mains cable, circuit breaker ... and a PCB that looks like a small PSU. - one big transformer - one small transformer - one H785 battery backup regulator module - one H745 -15 PSU module - two H7441 +5V PSU modules - a PCB that is labled "BATTERY CHARGER" - a bag full of screws Some time ago I got the front half of the BA11-K, i.e. a card cage with the system units, all UniBus cards, power distribution panel and front panel. Obviously missing: - back of the BA11-K where the PSU bricks, transformers, ... are mounted - fans - bulkheads for the console serial line, the serial multiplexer, RK07, ... - UniBus extender and terminator. [1] I got the card cage, power distribution panel, system units and all UniBus cards in one piece, but disassembled it to clean it. I know how to remount that, but I have no clue how all the PSU parts fit togeter and if there are some parts missing I didn't list above. It would be nice if someone who knows this machine could give me some hints... I was toled that one of the PSU bricks is broken. I found some manuals on http://www.mainecoon.com/classiccmp/PDP-11-34A/ but I can't read those TIFFs. I tried with xv, gimp, tiff2ps, Netscape 4.7x, Mozilla 1.2. I took the CDR with the TIFFs with me to work and tried to view them on a WinXP machine (puke). The machine nearly crashed when I tried to open the files. My SGI Indogo2 is broken so I can not try some IRIX tools. Where else can I get some schematics of the PSU bricks in a readable form? [1] There is an other, smaler BA11 with a custom UniBus interface from Linotype for some photo typesetting machinery... I have the M9312 bootstrap terminator for the "beginning" of the bus where the CPU resides. -- tsch??, Jochen, who is now heating the soldering iron for the Indogo2...

Categorization and description was RE: Collection policy was Re: No space for vinatge computers in

by CyndeM＠vulcan.com

I'm finding many aspects of this discussion very compelling. It got me to wonder some things. How would you categorize and describe classic computer items? Is there an accepted descriptive benchmark in the collectors discipline? Or better still, how would you *like* to see it done? What would be an appropriate descriptive level of a flip chip, a unibus terminator, a cable, a power cable, a backplane, a cabinet part? If you had a museum or archival collection of these DEC things, what would you want to know about them that would make them useful to you?

This is simply rediculous. A PDP9 is a PDP9 no matter what cabinet it's installed in, of even if it's jsut loose backplanes and PSUs... Mind you, I once saw a list of valves (vacuum tubes) that one museum was offering to another. The list had a column of 'condition'. No, it didn't give the emission and gm figures. It didn't even say if the heater was continous, and the getter silver (not white, which would indicate air had leaked into the valve). No, it described how clean the glass was... > I recently recoverd an entire PDP-9 OS thought long lost from three > DECtapes found in a batch of over 100.

The obvious extension of this is that art galleries should throw out all but 10 of their paintains on the ground that they 'already have 10 pieces of canvas with paint on them' :-)...

Checked voltage regulator pins on CPU card, 12 volts on the lower regulator, nil on the upper :-(. It should be interesting to watch the 8800 on ebay, it's got 4 days left. For almost two days (long enough to get my hopes up...:-(. ) I was the high bidder but now it's up to $1000. I wonder how sick this one will get? Ahh well, someday I will own an 8800!

TRS80 mod 4 ver1 video/memory problems

by jpdavis＠gorge.net

Hi, I recently picked up a model 4 ver 1 with a problem. The system originally worked and booted, after moving the system it started to display random characters on power up and failed to boot.. I removed socketed ICs and cleaned the connectors. The system now displays a blank screen on power up ( although the drives spin, and it could be booting ). If I disconnect the FD controller from the main board, the system jumps into basic ( with video ) and seems to operate. Print fre(0) returns somthing over 48K with the fd disconnected. Any hints?

OK. I've got an ftp server lined up, can even put them on CD's and duplicate a batch on scrap discs (don't ask, I was trying to calibrate a termal CD printer). The big question: What is the best tool to create the disk images? Rawread/rawwrite? dd? cpio? something else? The easiest thing for me is either dd under linux or raw read under MSDOS (like the linux boot discs). I have lots of 5.25" disc drives laying around. All I have to do is hook one up. I'd rather not create the 8" discs myself. The media on them seems to peel off onto the head if you have cheap ones. Then I have to take the drive apart, clean the head... since I've already copied most down to 5.25 (I still have to do mbasic, multiplan, and Profile 16+), I will make images >from the 5.25" discs as time permits and put them up on a public ftp server for a while.

No, that's backwards. In the case of DEC RX01 or RX02 with a DEC controller, the controller card (in the QBus or Unibus) is fairly dumb, it's just an interface. The "smart" stuff is in the drive enclosure. The controller passes a FORMAT command to the drive, the drive chunters away and executs it, and reports back to the controller when it's done. In the case of third-party controllers with "industry standard" drives, the controller is "smart" and the drive is dumb. The controller does the formatting, and sends control signals and a data/clock bitstream to the drive, so you can't do anything > The same situation occurred with the DEC RX50 floppy media. > The DEC RX50 drive could NOT perform an LLF. It works differently than an RX01/RX02. In fact it works exactly like the third-party RX01/RX02 case above, except that DEC saw fit not to include formatting routines in the RQDX1/RQDX2 controller. The RX50 drive is an oddly-engineered variant of an industry-standard 5.25" dual floppy, with almost exactly the same control/data signals. > However, by the time that DEC allowed the RX33 on the RQDX3, > DEC had switched to industry standard HD PC 1.2 MByte floppy > drives and media with 2400 blocks. Yes, the RQDX3 includes firmware that can do the formatting. However the layout it creates is fixed, and not useful for an RX50 (which has almost exactly the same hardware interface as an RX33). > The question that is still unanswered is IF the board that dbit > has available that supports the RX01 floppy media on a PC > with the appropriate 8" floppy drive CAN ALSO support > an RX02 media? I seem to remember that the answer is NO! Correct.

Very good! I've seen a similar proposal written by Fred Pohl in a book called "Digits and Dastards". The last two items in this collection (of mostly SF short stories) are entitled "How To Count On Your Fingers" and "On Binary digits and Human Habits" (copyright 1856 and 1962 respectively!). -- Pete Peter Turnbull Network Manager University of York

TRS80 mod 4 ver1 video/memory problems

by dwightk.elvey＠amd.com

Hi Jim There is a chance that the first crash also damaged the system info on your boot disk. Have you tried using another disk? You could also try putting the disk controller in but put tape over the select line( not sure what is involved here without a schematic ) and tie this line ( lines? ) so that the drive doesn't access. The idea is to see if something in the controller is loading the bus. If this is the case, BASIC won't boot. You could then isolate a pin at a time until you found the failure. Small pieces of tape work well for isolating edge connectors. That is about as far as I'm willing to make any guesses.

Thinline Floppy Problem

by univac2＠earthlink.net

What does it mean when the light on a thinline floppy in a Tandy 6000 repeatedly blinks to the pattern: <long blink>...<blink><blink><blink> When I put a disk in, the drive makes healthy noises, but the light just keeps blinking like stated above, and the system seems unable to detect that there's a disk in the drive. -- Owen Robertson

Hi As was mentioned, not all controllers do single density. MFM double density is no problem. There are a number of programs out there that handle differing sector counts and sector sizes.

If your disk are single density and you have a controller that handles single density then you are OK. Intel's double density was M2FM and not MFM, for the 8 inch disk. About the only way to read this was with an Intel M2FM controller. As far as I know, these only existed on multibus boards. Dwight > >Thanks again for the leads.

More Stuff for Auction at SYI

by marvin＠rain.org

I have listed some more stuff for auction over at http://www.sellyouritem.com. I have found quite a few DEC flip-chip and other boards that are being listed there in addition to other stuff of interest to listserver members. The area of main interest for list members is in the Classic Computer section at: http://www.sellyouritem.com/ListAuctions.html?CategoryID=1497 The things I am listing there are for 3 day auctions, and that should give everyone here a chance at them before they head over to (explatives deleted) Ebay. If you think the pricing is wrong, let me know as this was my best guess at reasonable pricing for list members. Again, the main idea behind putting them on SYI is to allow listmembers an equal chance at anything they might be interested in. I'm trying to list about 10 items/day there. Stuff that I will also be listing include a PDP-3L, Microvax, some DEC Disk Drive cartridges R????, and some other DEC cards that I have not identified yet. I *think* there are also several 11/34 cards that I have not listed yet, hopefully later today. ------------------------------------------- ebaY's Security Breach and Coverup http://www.auctionguild.com/generic110.html

This demo ALWAYS gets good reviews.... Exactly what I did with my 8-year-old niece at Christmas. She's really into "sums" and arithmetic at the moment, so when I wanted to play with my 8/E, I taught her a little about binary, showed her how to read octal off the switches and lights, and we added some numbers. She loved it. -- Pete Peter Turnbull Network Manager University of York

Thanks for the tip on the D Bit FDADAP. I will probably get one as I think it meets my criteria. I am not particular interested in reading DEC RX01 & 02s. Those I will pass onto the list as I find them. My main interest is in CPM systems and disks of which I have several. Also I wonder if it will work with intel development system disks.

Computer-tourism in Manhattan

by norm-classiccmp＠docnorm.com

Hi, folks. I'm starting a vacation this Saturday with a few days in Manhattan. Are there good classic computing or telecommunications museums, or other interesting sites, there? I know IBM used to have a museum in Manhattan, but I never got to see it -- I'd hate to miss something else just before it closed. Any help is appreciated, and I'll gladly take pictures and/or send postcards for those who are interested :-) Norm

DecServer 700 - WWENG2.SYS image

by alexandre.dulaunoy＠ael.be

Dear All, We have received a lot of old DecServer 700 but we are looking for the WWENG2.SYS image ;-) We have looked around the old digital ftp server, but there is only the pr0801eng.sys (not really useful). Where can we get the WWENG2.SYS image for the DecServer ? What is the software licensing for this image ? Is it linked to hardware or was it a separate product from Digital ?

Interdata Model 74

by toby＠russellsharpe.co.uk

Hi, I recently picked up a PDP11/34 for restoration from a surplus dealer and spotted at the same time an Interdata Model 74 gathering dust. Needless to say, I managed to get this as part of the deal.. I'd like to try to restore this back to working condition, but my various searches for information on early Interdata models seems to have born little fruit. Does anyone have any information, documentation, engineering diagrams for this machine? Thanks, Toby

AV11--Need advice.

by sherrill＠frontiercomputer.com

I ran across your 11/4/02 post about leaking capacitors. We have two (so far) PCs afflicted. What scares the crap out of me is that we have a number of them at customers as voicemail servers. You said you replaced with AV22 and AV18, and we'd like to find out if that'll work for us. I also read at overclockers how to replace capacitors. I believe both the PCs are 700 mhz Celeron running Windows XP. I'd appreciate any advice you can give us. Sherrill Lowrey sherrill(a)frontiercomputer.com

XENIX Distribution Disks

by univac2＠earthlink.net

Well, I found someone with a Tandy 6000 keyboard to sell and it should be on it's way to me tomorrow. Unfortunately, when it gets here, I will have nothing to use it for, as I accidentally wiped XENIX completely off my 6000's internal hard disk while trying to format a secondary *external* hard disk. I will never again assume that a program named 'hdinit' will actually ask me *which* disk to erase, nor that it will ask for *ANY* kind of confirmation before wiping the internal hard disk... So I am now in the market for some Tandy XENIX distribution disks for version 3.whatever. I don't know the exact version number of the OS that was for the 6000 specifically. Also, should anyone have the Multiuser BASIC disks, or Profile for XENIX disks, those were lost as well... I didn't have any of the original disks for anything dealing with the 6000. I'd also like to get my hands on something my system never had, whose absence was very noticeable - the XENIX Development System, which contains things like the C compiler, mail, and many other things I don't consider optional in a UNIX-based system. Any help is greatly appreciated... -- Owen Robertson

The Great Auction (Leaving the Hobby)

by cb＠mythtech.net

>How do you have a url if it isn't listed yet? I've >never heard of a delayed listing. When selling stuff on ebay, you have the option of setting your start date/time to something other than right now. It costs more to do this, but it is an option. So like Jeffrey's post said, the auction starts at 6pm PDT Wednesday. So I would assume the link will become valid as of that time (it would be nice if ebay gave you a slightly better message than just Invalid Item so you know you are looking at a not yet valid item as opposed to a totally incorrect listing ID) -chris <http://www.mythtech.net>

DEC Modules F/A at SYI

by marvin＠rain.org

I've just listed some M series modules and a Quad Extender Board over at Sellyouritem.com. The URL for the classic computer stuff is at: http://www.sellyouritem.com/ListAuctions.html?CategoryID=1497 These are set for a three day auction to give listmembers a chance at them. I plan on listing about a dozen+ items a day, so it might be worthwhile to check over there occassionally. We've had some discussion about First Come/First Serve, and that basically means whoever lives at their computer has the best shot at anything offered to the list. I think this might be a fairer way of doing things without giving the whole world a chance at stuff. SYI has *NO* listing fees, and FVFs are slightly less than on Ebay. My feeling is that a three day auction gives everyone on the list a chance to look at the stuff, and bid if they are interested. ------------------------------------------- ebaY's Security Breach and Coverup http://www.auctionguild.com/generic110.html

The Great Auction (Leaving the Hobby)

by jss＠subatomix.com

As promised, the bulk of my collection will be up for bidding in less than 24 hours. For an interesting twist, I have decided to sell my collection in one large lot instead of several medium-sized lots. This will hopefully maximize both convenience and entertainment. Remember, I'm also accepting items in lieu of cash. The auction kicks off today (Wednesday) at 6PM PDT (1AM GMT). I wish all contestants a safe, enjoyable bidding experience. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2732905006 -- Jeffrey Sharp

IBM 8560

by cb＠mythtech.net

Any value to an IBM 8560? Or more correctly, is it something that someone on the list might be interested in. Its a full height tower 286 IBM ps/2 machine. There is at least one hard drive in it, and I think I have a 2nd for it (not sure the sizes, 20 or 40 MB I think). Last I knew it booted and worked fine. I've had it kicking around for some time, and its taking up space. I think it weighs about 40 lbs, so figure on 50 lbs packed for an estimate, shipped from 07450... anyone want it? -chris <http://www.mythtech.net>

LA 120

by marks＠techprecision.com.au

Hi there I saw your post as a result of my search criteria in google, i am chasing any and all documentation on DEC LA 120 and any other relevant PDP material. I have just secured a position with a company that supports this type of hardware, and am having difficulty wrapping my mind around the sheer immensity of the equipment. So any help would be very much appreciated, as i search and search for any documentation. :) Best regards Mark Setter
