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?

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.

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.

No, these were not used in the Tandy 2000, but I
guess they were used in something (some terminal
perhaps?). Mayhap someone on the list knows.
O why o why couldn't they have been 9007s or 9021s???
Why. O God...

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

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.

Hi - I finally got a Lobo Max 80 to boot
http://www.vintagecomputer.net/lobo/
I'd like a copy of the LDOS 5.1.3 manual so that I can review the options
and parameters associated with the dos commands.
Thanks in advance

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.

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)
