I would also add that if the modification was simply board-swapping or chip-swapping (e.g., an overdirve processor in a PC), then I think that it would be more permissable to undo the swap. On the other hand, in general, I would leave in place a soldered modification. Indeed, such a mod might have been factory original, as I have seen a number of main boards with cut traces and hand-soldered wires snaking over the board. There will be times when the collector can not tell if the mod was "factory" or "aftermarket". A greyer area is the following: I bought a Tan-case Osborne 1 early on. Later, I had it upgraded with the 52/80/104 column display option and double density disk controller. As a "collector", does one remove the upgrades and have an "original" O1 (and it was used in the original configuration for quite some time), or keep the mods and have a fuller representation of the product's lifetime? Personally, I would keep the mods.

If you are merely a collector (I like to consider myself an "archivist") I think the modification is part of the historical fabric of the machine, and changing it would alter that history. If you're just a hacker, and you intend to continue use of the machine, then any change you make becomes part of the historical fabric of that machine. It just depends on how you look at it. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Scanning Microfiche

by healyzh＠aracnet.com

I think it's time to revisit the ever popular topic of scanning Microfiche. I'm in the market for a new scanner, and ran across the "Epson Perfection 3200 Photo" scanner. I was looking at it, because it's one of a very few Firewire scanners on the market. What really got me to thinking though, is the fact that it is a 3200x6400dpi scanner, and has a 4"x9" transparency adapter. This has me wondering if it wouldn't work for scanning Microfiche. Does anyone have any thoughts on the subject? Zane -- -- | Zane H.

Wang Computer Systems/schematics

by luc＠e2t.be

About the OIS140 system I am sure I have all the schematics (at least till 1981 - the year I left Wang) About the terminal - I have only known the all-in-one versions (there were 2 models I think, one was 8080 based, the newer one Z80 based) The problem might be to reproduce them - in those days schematics were real blueprints - size at least A3 some even A2 (sorry but I can not translate this to "other side of the ocean" format) in any case to large for my scanner. During the years they also colored pretty brown or gray, so I am afraid a regular copy might be hard to read. If I had the time I could redraw them in a schematic program but time is one of the things I miss most in my life... It was goo to see this old OIS140 back on your website - I haven't seen one since I left Wang. If I could find one in Europe, it would be a pleasure to start it up again. I 'll try to find the floppy disks back - I had all system diagnostics, games (you the good old cave...) and so on...

IBM 029 punch gets $603

by vcf＠siconic.com

I'm a bit surprised at the result of this auction: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=2734334833 I suppose it makes sense that these things are getting harder to come by, but I think the $603 top bid is a tad high.

Restoration: how far should it go??

by Robert_Feldman＠jdedwards.com

I had my Otrona 8:16 upgraded from 256KB to 640KB RAM, so it now has stacked chips. However, that was a mod done at the time (actually, Otrona Advanced Systems had gone under by then, but it was a 3rd party (Brown Enterprises) mod that was current with the machine.

Wang Computer Systems post on CCMP.

by dtillson＠xmission.com

Yes I have both a Wang Professional Computer and a Wang WLTC. The Wang PC has both a B&W and Color Monitor. The Color Monitor only functions with Wang programs. The B&W monitor functions with both Wang and DOS programs. It has been a long time since I have run the PC system but as I recall the version of DOS it carries is 2.X. There are two 5 1/4 disk drives and lots of disks. The WLTC has a built in thermal printer. Not sure what version of DOS it carries but as I remember it is the same as the PC. It has an external 5 1/4 floppy drive. The WLTC also comes with a canvas carrying case. David Tillson Salt Lake City, UT At 05:23 PM 6/12/2003 -0600, David Vohs wrote: >Saw your post on CCMP.

SMS 1000 Chassis documentation wanted, Bounty offered

by stuart＠stuartsjohnsonfamily.net

If anyone has a documentation set for the SMS 1000 PDP-11 chassis, please contact me offline if you are willing to loan or sell me a copy of it for a "reasonable" price. I am not looking for an item to be put under glass in a museum - I need working documentation. I bought one of these chassis's a while back (less docs) and can't use it without some assistance. I don't even know what "style" of QBUS it has in it! The chassis was "supposed" to come with the manuals, but... it didn't. It is too heavy to ship it back to the seller; the total shipping cost both ways cost about the same at the item did. I'll pay $20 US for information to the FIRST person (by email received time & date) to point me to a source for this documentation, that leads to my having a copy in my hands. If that person also is an owner of the documentation willing to provide me with a copy, I will pay them the $20 plus a reasonable copying and shipping fee. There are exclusions, to my bounty offer but will not affect anyone but the original seller of the SMS 1000. Stuart Johnson

SparcStatiion 10

by jrice54＠charter.net

I picked up a SS10 yesterday. It was missing it's power supply but had a 24bit framebuffer a 10/100 S-Bus nic, MBus processor module, some ram and a hard drive. Seemed like a restorable pizza box and since I don't have a 10 I bought it. I got it home and the Sun p/n guide tells me that a SS10 uses the same power supply as a SS5. I have a couple of spares for my 5's so I got one out. There is no way it's going to fit in the chassis. The SS10 chassis has a beveled cast ridge where the power supply should slide into. Is this a real SS10 or was the label switched? Was there two different versions of the 10 chassis or power supply? I'd like to trace it all out and get it working but for a $10 investment, I can salvage out the parts and still feel that I got a good deal. James

OT: Rant about UPS...

by SUPRDAVE＠aol.com

Remember that UPS stands for United Package Smashers Ive heard that they require enough packing to survive a 6 foot drop which is what they probably do to every package just to make a point. I avoid using them. I've always had good results from the USPS. In a message dated 6/16/2003 10:21:45 AM Eastern Daylight Time, jcwren(a)jcwren.com writes: << It's all very dependent on the store. I have one near me that I use, since the nearest Fedex and UPS counters are miles away. I have a good relationship with the people there, and they understand how to pack most items. Generally, I'll give a specification how I want it packed, and they'll do exactly as I ask. They know to put tape over lables in case they get wet (preventing running), triple taping bottoms, double taping edges, etc. >>

Looking for... (phaser 350 info)

Trying to finish repairing a Tek (ne: Xerox) Phaser 350 printer, and while I've got most of the major gremlins beaten down, there is still one fault that I can't get sorted. So... I was wondering if someone out there might have a copy of the interactive diagnostics package (350diags.exe) and (hopefully) the pinout of the 'service port'. It is supposed to be RS-232 but comes out on a 5-pin inline connector... (figures) Thanks; -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw

HP 9000 R332 computer

by peterbrown10＠hotmail.com

Hi Joe, I was having a quick play with an R332 9000 machine at the weekend and noticed a couple of other 'interesting things' about it. 1. Further to my mail about the extra rear panel jumper leads required to make this things work. It appears that the FDD mounted in the front panel of the computer is linked to its own controller card that is in turn linked to a rear panel HPIB connector. In order for the computer to see the FDD, a short HPIB connector must be used to link the HPIB connector on the rear panel of the computer (vertically orientated) and the HPIB connector on the plug in CPU card. 2. On close inspection of the FDD controller card, it appears that there are two disk connectors of different lengths (one is the FDD controller). The disk connector is open - could this be a connector for a HDD? If so, it doesn't look like an MFM connector - it looks much more like a regular IDE connector. I've seen references to an internal HDD option for the R332 - is it possible that this drive is an IDE type?

HP1350 Graphics Translators

by peterbrown10＠hotmail.com

Hi All, Thanks for the info on programming the 1350. I picked up another one of these HP vector displays, a type 1347 (I think), at a surplus store. It sounds pretty similar to the 1350 except that the display tube is built in to the device. I think that HP used these displays in quite a few of their spectrum analyser instruments to generate the fancy displays that are required for frequency domain analysis. The 1347 was available in either free-standing cased form or as an open cage that could be integreted into third party instruments. 3 BNC connections on the rear panel allow you to drive an external XYZ display if you need to. I'll have a try drawing some pictures using the programming information that has been posted and let you all know if the commands are the same.

Restoration: how far should it go??

by swtpc6800＠attbi.com

> How much do people think is too much restoration??? I try to get my machines running as they would have been in their prime. This includes making the common upgrades that most users would have done. Since I am restoring kits, there was wide variation in assemble quality. If I have or can find the correct parts I am just finishing the assemble 25 years later. (I am talking about adding a capacitor or a minor cut and jumper. Not increasing the memory by tacking RAM chips on top of the original ones.) I want the machine to work, even if I have to replace parts. I restored a SWTPC TV Typewriter that had been very poorly assembled in the 1970s by stripping the boards bare. (This is not the first choice procedure.) I was able to find accurate replacements for almost all of the parts. http://www.swtpc.com/mholley/CT_1024/Restore/CT1024_Restore.htm I also build new upgrade boards for SWTPC 6800 computers. Some of these use current production parts and some use historical parts. These can added to a system and removed without damage. (I sell copies of some of my upgrades but I make them for my own use. Which is a good thing because I will never recover my cost.) http://home.attbi.com/~swtpc6800/new_stuff.htm Sometimes a hand wired board is a accurate example of what the original owners would have used. http://www.swtpc.com/mholley/QRC_Proto/32kMemoryIndex.htm These upgrades allow the base level product to be upgraded to a full featured version so you can run the vintage software. Another area of restoration is documentation. I have been scanning documents, converting them to text, then creating PDF files for the web. I correct the typographical errors in the originals and add corrections. I don't try to maintain the exact format or pagination. I do identify major changes that I make. I have been taken to task of not preserving the original documents with all of the errors! Michael Holley www.swtpc.com/mholley

IBM 3101 terminals

by elmar.schmitz＠smail.emt.fh-rhein-sieg.de

Hi, I just got 2 IBM 3101-Terminals. The display unit and the documentation is missing. The only written stuff I have is the "Customer Problem Analysis and Resolution Guide" which stuck under the Keyboard. Can anyone send me a mail with documentation? Fortunately I have lots of spare Monitors, but I need the pin outs of the video connector to solder a new cable. Does anyone has an schematics for the devices? elmar.b.schmitz(a)batronix.com I want to plug the terminal in my Linux-Server. I pulled an additional RS232 along the cat5 cables for administrative work. It is a bad idea to change network settings over telnet if the devices won't restart. And why have I to use a PC with 200W power consumption if I just want to type in some Stuff? And an ASCII - Terminal is cool, too. Thank you, Elmar

Restoration: how far should it go??

by ptremewe＠bigpond.net.au

Hi all, Being a new comer to the hobby, I have not posted much on the forum before. The subject however is one that has recently been brought to my attention, and hopefully will bring about some debate. Here is the scenario. You've just come home from the Antique show/Trash and treasure/garage sale. You've picked up a nice new toy, hopefully at least a little less than the price you should have paid. (With the blessing of the other half of course) You know it's not a worker and have a general idea of the condition of course. You just can't wait to get it back to the workshop. You take the cover off and...... How much do people think is too much restoration??? Now obviously you aren't going to spent thousands on a system that even in the distant future will not even generate hundreds, and obviously you aren't going to rebuild and replace every part in the item, because then it's a replica not an antique. Obviously however a going system is more valuable than a broken one. So to what lengths do you go to fix it?? For quite some time I have had in my possession a fairly old system that I am told is "historically significant". For those that know what one is it is an EDUC-8 a descrete logic CPU/Programming trainer from the mid 70's. There seems to be two main opinions among computer collectors. Opinion 1: The collector who collects entirely for the sake of owning the object in question and is not concerned about operating it or whether the item works as planned. They will buy an antique for preservation and think it is sacrilegious to do any restoration other than maybe a "spit and polish". Opinion 2: The collector who collects with the intention of restoration. Who might go to extreme lengths to rebuild and restore the item he has brought, because to him the idea of keeping something that isn't working as planed is against God and nature. Without getting into protracted discusion about the theology of either collector, I would like to hear the opinions on the list about how far a restoration should go before it starts detracting from the value of the piece. I know this is a complex issue, and obviously depends on allot of factors, but surely there are SOME guide lines that should or could be followed. I am about to start a complex restoration on the EDUC-8 and am hoping the experts on the list will give me some ideas based on their experience with other systems. Idealy I would love the thing to be actually working. Possibly with some replica I/O interfacing. I must say the the system is at best in "fair to poor" condition, and without some attention it will probably deteriate further. I supose I could just clean it up and place it in a "display case" but I tend to be a collector of more the second opinion than the first. Obviously however I do not wish to "distroy" the "vintage" significance of the unit either Hope to hear from you soon..... Peter T.

Seeking HP1000 interface manuals...

by bshannon＠tiac.net

Hello, I've been developing 'device drivers' for some HP1000 boards to allow those devices to be run under a freeware HP operating system and programming language. There are a few boards I don't have documentation for, but would like to offer drivers for. Here is a list of HP interface manuals I'm looking for: 59310B BUS I/O - the standard instrument control HPIB bus interface board. 91200B TV INTERFACE - apparently a NTSC bit-map video display board. 12554A 16-BIT DUPLEX REGISTER - I understand and use this board, but I have one or two that need repairs. 12968 ASYNC COM INTERFACE - apparently the BACI boards little brother? 12972 8-CHANNEL ASYNC MUX - 8 RS-232 serial ports on a single I/O card. The top 3 are higher in priority than the last two.

Iomega floppy tape drives + software

by julesrichardsonuk＠yahoo.co.uk

hi all, I stumbled across a load of old QIC 80 tapes of mine today and got curious as to what might be on some of them. I managed to dig out the relevant tape drive >from storage (it's an Iomega drive - 3.5" bay sized - with a floppy interface; slow as hell from what I remember!) I haven't used this thing for years but plugged it into a machine running NT4.0 - amazingly NT detected it and has installed low-level drivers for it, so I'm hopeful that the drive will still work. Of course I have no software for NT that'll read the format on the tapes... Problem - can't find the relevant DOS software either. I probably chucked the floppies a few years back knowing me :-) I do remember way back (actually would have been 1993 or so - just on topic for the list!) using another vendor's software under DOS though. Software was for the Jumbo series or drives that were around at the same time; different vendor but it worked with the Iomega drive too. Not that I can find a floppy with that on either :-) Anyone got one of these drives or a pointer to the software on the 'net? No problem booting the machine under DOS to access the tape drive - I doubt there's any (free) NT software around that'll read the format on those tapes. That's assuming the information on them hasn't vanished anyway of course... cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

HP 1631D logic analyzer, some basic questions:

madyn(a)ix.netcom.com (Harvey White) writes: > I'll have to see if I can find data on HP-IL, might be worth rolling > an interface for it, or just stick to the IEEE-488.... The most common configuration was a 9121 or 9122 floppy disk drive attached via HP-IB aka IEEE-488. I used to be the product support engineer in the factory for the 163X family circa 1986, and probably still have a full, annotated service manual at somewhere... but I'm on the other side of the planet at the moment and won't be home for several weeks.

OT: Rant about UPS...

by cb＠mythtech.net

>As others have mentioned, Fedex Ground is usually cheaper. Just watch it on the FedEx Ground pick ups. They charge an $11 weekly fee for each week a pickup occurs in (one fee, as many pickups and packages in the week as you want). If you send rarely, this can very easily negate the price savings over other carriers like UPS since you can't spread the fee across multiple packages. Of course, you can do what I do and just drop the package off at a FedEx depot and then they don't charge you the fee. -chris <http://www.mythtech.net>

OT: Rant about UPS...

by dwoyciesjes＠comcast.net

I'm sure you guys will enjoy the humor in this... I went to the shipping counter at the UPS hub here, with a box that has an Atari 800, disk drive, and software. The guy at the counter asked what I was shipping... "Oh, just some software, and an old computer and disk drive." "Copmuter? It that the original packing?" "Huh? Uh, no. It's an _old_ Atari copmuter." (Confused glance from him at the mention of the word 'Atari') "Well, uh, lets take a look...What's this?" "Umm, A disk drive..." "Well, uh, we can't ship it like this. It has to be in the original box" "Really. Since this computer is about 20 years old, I highly doubt that the original boxes still even exists in this world. So now what am I supposed to do?" (Blank look from him)"Well, let me tape this box back up for you" As I take the box to the FedEx hub next door, I wonder where this guy has been in the 80's. He has to be at least 30 years old... -- --- Dave Woyciesjes --- ICQ# 905818

Power Supply Problem?

by jhfinexgs2＠compsys.to

I could use some help with a hardware problem?? PLEASE!! Two weeks ago, my system crashed because both hard disk drives failed. I replaced them (and sent the bad ones in for replacement under warranty), but did not do anything else since at the time it seemed that the more likely problem was something random. Some additional information - I looked at the disk drives before they were returned for replacement and they would not spin up when the logic board was still connected, but when the logic board was disconnected, spin-up did take place. It seems likely that the logic boards were fried. Just last week, the system crashed again and would not even power up. This seemed to point to the power supply and it was replaced. Now the system is working perfectly again. The latter time, the replacement disk drives were not harmed. Can anyone help with a reasonable estimate as to whether or not it seems more or less likely that the cause of both problems was the power supply or not? The system had probably been running a total of about the equivalent of 3 years of continuous use. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

On the other hand, they also offer a nice "scheduled delivery" feature for residential deliveries. You can tell them what time of day you want it delivered. But you do pay thru the nose for this (I think the one time I looked at it, it was an $8.00 surcharge on a $10 package). -chris <http://www.mythtech.net>

>I have to take the box(es) to the FedEx folk, since >one of the reasons Ground is cheap is that they don't provide pick-up >service - but since FedEx locations are easy to find, They do provide pickup to some areas. But they charge an $11 a week fee for any week in which pickups occur. I do have them pickup from my office when I can charge the cost off to a client, or when the packages are just too damn big for me to bother taking to the depot (like Friday they picked up 5 50lb boxes full of laptops... too much for me to bother hauling to the depot, and I could charge the $11 directly to my client so I didn't care). -chris <http://www.mythtech.net>

Siemens 6-611: Wierd yet cool

by toresbe＠ifi.uio.no

I recently found a computer to which I have never seen likes: The Siemens 6-611. Although I'm just getting started within serious collecting, this is an interesting machine. It features more than one 80851 (I counted 4), A Z84, and a bunch of AY-something chips. It has a v. large mainboard. It has a console I think is serial, with a wierd textile covering the CRT. The console is also labelled 6-611. The keyboard features indicators like ACK and a sexiful key. The monitor powers up, beeps, and the OK light on the KB lights up. Mass storage is an 8" drive, and a large HDD, 8" style. It has two separate power connectors, one for the hard drive logic, one for the motor and mechanics. Upon powerup, smoke erupted from the powersupply, which I think were filter caps. (ARGH, the SMELL!) The system worked fine after that. The monitor has a power switch and AC out for the system, which doesn't. The monitor also regulates the power to 230v (In comparison to 235v in Norway.) I lacked the cable from the console to the machine at that time, a standard serial cable, DB-9.
