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. What Tony was objecting to is a modern collector hot-rodding an old box by increasing the RAM (or processor, or ...) in a way that would not have been done contemporaneously with the machine. -----Original Message----- From: Jim Davis [mailto:jpdavis@gorge.net] Sent: Sunday, June 15, 2003 2:13 AM To: cctalk(a)classiccmp.org Subject: Re: Restoration: how far should it go??

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 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)

They are now called "The UPS Store" here in Chicago (at least).

The guy behind the counter was also a real jerk about it.

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.
