While we're on the subject, did anyone see the article "Data Extinction" in the October 2002 issue of Technology Review?

I know that some of the WW1 German Fleet scuttled in Scapa Flow has been cut up to obtain clean steel -- I've been there and seen the remains -- and I found a reference in the sci.military.naval FAQ to the salvage of German U-boats, but as far as I know, most of that sort of steel is/was wanted for large objects like some of the devices used in research labs like CERN. I found another reference about Fermilab seeking radiologically clean steel some time ago, but not much else. The FAQ points out that the U-boat salvage rights haven't been exercised (and Scapa Flow hasn't been emptied either) so perhaps the demand is too small. The steel can't be resmelted, and possibly not welded either, so if it's to be used, I guess it would have to be of suitable size/thickness to be mechanically cut and formed. Oh, and don't cut it with a torch if you want to sell it as "clean"! -- Pete Peter Turnbull Network Manager University of York

Clean steel?

by kapteynr＠cboe.com

My understanding of this: "Unclean" steel is not radioactive because of the A-bomb tests (although we are all being exposed to roughly 3 times "natural" background radiation because of those tests. There have been several very expensive mistakes in which highly radioactive contaminants got mixed in with scrap metal going to smelters. Some of these were not detected until toys and table legs made from the scrap were being shipped to consumers. About 40% of our steel comes from recycled scrap. This scrap always seems to pick up some radioactive contamination. The 60% of steel made from virgin ore is "clean". Your 1930's scrap is still scrap -- not virgin ore. The EPA has a new program to address this problem: http://www.epa.gov/radiation/cleanmetals/ -Rob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]On Behalf Of Sellam Ismail Sent: Thursday, October 17, 2002 10:51 AM To: Classic Computers Mailing List Subject: OT: Clean steel? There are two rooms in the ACCRC building that are filled with huge old (useless) refrigeration systems. Tons of steel. We'd like to get the rooms cleared out so we can use them. We've gotten quotes in the past but all of them will end up costing us to remove the equipment since the rooms are enclosed and one of them is down a ladder with a narrow door. Everything will need to be cut up and removed piece-meal. There is also some very large equipment on the roof that will need a crane to remove. A while back we had a brief discussion about "clean steel". "Clean steel" is supposedly steel that was smelted before the first atomic bomb tests, and therefore contains no radiation. Apparently, air since the first atomic bomb test is now filled with background radiation, and because so much air is used in the smelting process, a lot of the radiation gets into modern steel making it unsuitable for some applications (such as medical test equipment where radioactive isotopes are used as part of the operation). I was thinking that because this building is so old (from the 1930s) that a lot of the steel in those rooms is "clean". I called a scrapper yesterday who has been in the business for 30+ years and is a Harvard graduate, and he said he has never, ever heard of "clean steel". So what gives? Is there a government website somewhere that defines "clean steel"? I'm hoping that the steel is actually worth enough to make it a wash to have it removed. As it stands, the quote I have so far is that we have $25/ton worth of steel and $30/ton to salvage it.

Even electronics is not changing that fast, but if your computer is more than a year old, you are no longer"state of the art".

Reading HP series 80 ROMs

Selling old(er) computers in NJ

by cb＠mythtech.net

I'm having a garage sale this weekend in Northern NJ. I will be selling off most all of my 486 and earlier systems. Now I know this isn't of too much interest to people here... BUT, I will also have available the 4 IBM System 23's that I have yet to unload (not do to lack of interest, but due to lack of my ability right now to ship). As well I will probably have some other odds and ends of older machines and equipment. (ATs, and similar, dot matrix printers, a few laser printers,... I have to see what all I have). I may also have some older Macs (all 68k, most 030 or lower), I have to see what I have that I don't currently have a use for, and can bear to part with (I might have enough Mac Pluses and SEs to unload a few, if I can bring myself to doing so). I'm not expecting to get much for the PCs (if anything, really I am putting them on the lawn to see what I get before they are stripped down and thrown out), but I would like to get something for things like the IBM System 23's. There will also be some older A/V equipment, but the only stuff probably of interest here would be some 3/4" Umatic VCRs, the rest is just older amps, tape decks, and TVs, nothing fancy. And of course some of your normal garage sale fodder (I'm bringing some junk over from my house as well). If anyone is in my area and wants to stop by, let me know, I'll give you directions. Its in Ridgewood on Franklin Turnpike on the front lawn of my office (as well as some inside, we have odds and ends of office equipment to unload, and I don't feel like dragging it all outside) -chris <http://www.mythtech.net>

FS or FT - Bare Cromemco System Three

by SecretaryBird＠SoftHome.net

I still have that stripped down Cromemco System Three taking up space here and serving as a shin-bruising hazard in my living room, if anyone in the Pacific Northwest is interested. All it has is a pair of 8 inch floppy drives. I'm open to reasonable offers on this (not sure what would be considered reasonable, truth to tell). Cash is always good, but a trade would be nice as well. I would especially be interested in getting a Commodore PET (the type with the full keyboard instead of the chicklet keyboard, and perhaps a disk drive). The only catch is you would have to come pick it up, as I still do not have a working vehicle to deliver it myself. Any takers? -- Scarletdown

Location of Cromemco System One Revealed

by SecretaryBird＠SoftHome.net

I finally heard back from someone at my unit on the location of that Cromemco System One and Hard Drive. I was told that it went to Re-PC in Seattle (I'm assuming that they didn't mean the one in Tukwila). So hopefully, some collector in this area can find it and score it cheap. I had my shot at it earlier in the month and blew it. Live and learn, I guess. I simply didn't have enough information to go on when deciding what pieces to bring home. There should also be a System Two there as well, since there were two of them, and I only took one. Happy hunting! -- Scarletdown

I need some help in reading some RK05 packs. I have 17 RK05 packs and I have been able to read 14 without a problem. Two others have 14 and 5 bad blocks, respectively. The last has 1231 bad blocks. Is there any reasonably easy and simple way to recover the bad blocks. These are all RT-11 distributions prior to V5.03 of RT-11. In particular, the one with 5 bad blocks is a copy of another pack, so I was able to verify that the other 4797 blocks were the same. One down! The ones with 14 blocks and 1231 blocks are for V3.0B of RT-11, but they do seem to be a bit different. The 14 bad blocks are all in 5 OBJ files (for FORTRAN IV) an I may be able to find a copy elsewhere. The 1231 bad blocks seem almost hopeless unless I can find the same distribution and verify that the rest are OK. Obviously there is no point in spending any money since eventually someone will find a set of files for V3.0B of RT-11. Any ideas. I have tried to read each bad block a number of times - one at a time, but no success. I only have until Friday when I will be giving the RK05 drive and the borrowed RKV11D controller to Ethan Dicks.

Questions about a HP Apollo 735/125

by 520055239069-0001＠t-online.de

Hi folks, I just 'won' an old HP Apollo 700 Series, Model 735/125. Unfortunately, I don't have ANY information about it - searching HP's website took me to the service manual, so I know a little bit more about it now. By searching the web, I've learned that I can use a standard PC-VGA monitor with the apollo, by soldering (or buying, :-( ) a special cable. But, a few questions remain: - Anyone has a PIN-layout for the monitor cable? I know that I have to solder red to red VGA, red ground to red ground, and so on, but I don't know the pinout of the VGA connector... Maybe anyone did this before, and can tell me the correct PIN-to-PIN assignments?! - Can I use a standard PC keyboard with the Apollo? It just has a so-called "HPIL"-connector on the back, and I don't have such a keyboard... - What about a mouse? Unfortunately, I just got the machine, and nothing else... - My Apollo doesn't have a standard LAN-connector, just an AUI... But, I saw it has a EISA slot, and the manual told me that EISA is fully compliat to ISA (didn't know this before...). So, can I just equip the Apollo with one of my old ISA Novell/ Eagle-cards? There's an EISA card in the slot, but this seems to be a Token Ring (it's called a "Ring" card) Sorry if my questions are a little bit stupid, but I don't know anything about the machine - just got it from dumpster without any additional informatins, and thought it would be nice to use it. Thanks for your help, I'm glad that there is a mailing list dealing with this systems - thought I've just got > 10kg of old iron, when I start searching the web, :-) keep on hackin', Harald (bofh(a)dh9dat.de)
