Since being told about this list (looking for NCR 3434 system 3000
info), I've become enthused a bit more as to some of my interests in old
computers and bits. I have to admit that up until now I've been
scrapping them because there is a limit to how much stuff one can keep
and I could never find anyone who wanted them.

OTH, my working network consists largely of 486 and Pentium computers,
because they do the job(s) I need.

Of most use, to people in Australia, would be my list of surplus
hardware.
http://www.woa.com.au/linux/lists/surplushardware.html.

This list was established for the purpose of ensuring that old hardware
was given another chance of life. Very rarely somthing gets used (uni
students satellite tracking project, camera pan and tilt, occassionally
systems to deserving poor, etc). Most of the time, it resides here for a
few years, then gets de-chipped and binned/recycled/foundry metal/etc.

I say "in Australia" because shipping is kind of expensive for this
stuff and I'm not out to make money, nor do I want to loose money, so I
don't do COD, send on spec, bill, etc. If you are fussy, third saturdays
each month are usually open-house for Linux and other computer stuff.

I have sold stuff off the list, some network cards, to folks in the USA.
I packaged them up, then they organised shipping and sent me a cheque.
So if you are overseas and want stuff, then that is the deal. They were
also honest, decent folk and paid a fair and reasonable price above what
they had previously purchased these cards at because they were getting
harder to find.


If stuff like Z80 CTC and other chips are useful, then I am very happy
to start a chip list as well. Over the years, I've kept any socketted
chip on any board I have thrown out. It will be a "if you know what the
numbers mean, then it is yours" sort of deal. This will take some time
though as there are about ten large plastic bins full of chips, motors,
wires, etc to be sorted and accessable storage system worked out.

I noted the recent RAM chip messages and now know why each time I just
couldn't through out those memory boards populated with ram chips.


As to auctions, I'm not in this as a way of making money. I do this for
the same reason I help the local kids maintain their bicycles (I like
bicycle and see them a serious mode of transport for cities and a
legitimate recreational tool). That madness has spread to providing four
computers for the kids to play games on. When they can read and are a
bit better at arithmetic, I'll find those old text mode basic game
listings and the PCC games book I have and get them started on coding.
In time, they might end up as linux coders.
