I'll venture a guess and say the vast majority of people on this list are interested in the collectible/nostalgic aspects of old hardware, not for recycling. How much old *scrap* is there left these days? > The guy is shooting high, but not very high. $5.00 a > pound for really > good boards is not insane. Just how much gold (after considering the costs of extraction) in monetary terms would a $5 pound of scrap yield? I don't see any figures to that effect. ____________________________________________________________________________________Pinpoint customers who are looking for what you sell. http://searchmarketing.yahoo.com/

Apple IIe/gs/ older-Macs available in Fargo ND

by dave06a＠dunfield.com

I've been contacted by a lady in Fargo ND which an Apple IIe, IIgs and some older Macs. Also mentions printers, accessories, software and magazines all pertaining to Apple. She mentioned "a least pay cost of shipping", so I don't think she is looking to get anything for them. If anyone wants to give them a home, please contact me and I'll forward her email.

SMC CRT controllers on eBay

Mayhap someone on the list knows. O why o why couldn't they have been 9007s or 9021s??? Why.

Semi-OT: Need help identifying diode specs

by pat＠computer-refuge.org

I picked up a few spare diodes from my local surplus place, and I need some help identifying them.. They're about 3-3/4" long and 1-1/4" wide at the (hex) mounting base, have a threaded negative terminal, and an approx 1/2" diameter positive terminal on the top. They appear to have a Westinghouse (underlined W in a circle) logo on them, next to a diode symbol marking polarity. Next to that is the number "18840100" (part number?) and "8206" (date code?). Any idea what voltage and amperage this diode should be rated for? I tried googling for info, but only found a few places that wanted to sell me one (with at best the info that it's a "semiconductor diode".. gee, thanks). One site also listed the part number "5961-01-198-6175" as an equivalent. Thanks much, Pat -- Purdue University Research Computing --- http://www.rcac.purdue.edu/ The Computer Refuge --- http://computer-refuge.org

Looking for Hardware

by ploopster＠gmail.com

Please let me know if you have this hardware you wouldn't mind letting go for a small sum of money, or if you know where I might be able to find any of this hardware cheap. Thanks. IBM XT-286 Motherboard (I have a dead one that needs replacing) Kingston SX Now! 386 upgrade (For my beloved PS/2 Mod 50) Any AT-class memory boards (including EMS ones, obviously XMS preferred) Again, thanks. Peace... Sridhar

[more-or-less-offtopic]:68301 stuff

It depends on what you've got, but you might try finding a gcc cross compile toolchain, for say linux (or even cygwin) and then using the "objdump -D" program. You can get it to disassemble from an unformatted binary file... that is sometimes useful if all you have is roms. I think gdb has a 68k emulator, but if not there are many around to choose from. You should be able to quickly whip up something to sim the code once you've figured out the basic structure, i.e. where it boots form and where it expects ram, etc... just a thought. i'm big on simulation. There may be other tools for win32 I don't know about. I'm most comfortable with linux/unix & gcc. You can certainly build 68k code with gcc. I did it for years. -brad

Sun, HP "scrap" (???)

by dasbooterror＠gmail.com

As it goes, having actually run the gold scrapping grunt work (Read: Play with the Aqua regia) The reason you don't melt gold like that is the sheer amount of energy you have to waste to do it! Not to mention contaminating your final gold product with whatever crap is in the batch. As other people mentioned you can use mercury or cyanide agents, but good luck getting ether of those agents in any quantity, much less an EPA permit to use them for gold refining. Aqua Regia is bad enough, as you need to neutralize it before disposal. As it should be noted we refined chips, leads and anything gold plated Our usual contaminates were tin, lead, platinum, silver and iridium. ( Note: Using your left over Nitric Acid to make RDX does *NOT* count as disposal; However its a lot of fun)
