I've had these sitting in my garage for quite some time, and I thought maybe
someone out there could use these things.

I have a large quantity of old RAM chips.  The markings on the chips are
"JAPAN 8512" "HM6264LP-15" and "T0002550".  Once I looked these numbers up,
and I seem to remember that these are 8kx8 low-power RAM chips, 150ns.  If
you have any use for them (maybe a craft item?) give me a holler.

I also have a bunch (over a hundred) of these little boxes labeled "Microstor".
These are interesting little boxes, 1.875" x 3.875" x [1.5"|1.0"] (I have 2
sizes, all measurements are approximate).  On the outside, they say "Microstor"
and "Atlas Corporation Limited New Zealand", and have a serial number and a
model number.  They sport a 15 pin male D-connector, like an odd serial port.
The boxes are VERY sturdy, 1/8" thick plastic with a sealing lip around the
edge and brass grommets in the screw holes.  Inside, I have found anywhere from
1 to 4 of the above mentioned RAM chips (socketed), a lithium battery, and a PC
board with 2 diodes, 1 capacitor, 1 resistor, 2 soldered-in yellow chips (look
like resistor packs to be, but I'm no expert), 6 small socketed chips, and a
connection to the 15-pin port.  I've disassembled about a half a dozen of these
things, and the connections to the port seem to not be consistant, but 7 is the
largest number of pins that get connected.  it LOOKS like some sort of portable
memory system to me, but not being a hardware hacker I didn't really feel like
rigging a connection to one of my serial ports to experiment too much.  If you
know anything about these boxes, or if you'd like some to play with, please
send e-mail.

While I'm making a list of things... maybe you're interested in a couple of old
broken monitors... one CGA (nice monitor, with amber/color/green switch) and
one MONO monitor.  I KNOW the CGA is dead, I don't have any way to test the
mono monitor.

I've also got an old CPM system (Xitan Alpha "mainframe", z80 processor, maybe
64K RAM, dual Micropolis 5.25" floppy drive) I'd love to ship you.

Interested in a Seagate ST277R with RLL controller, was flaky before it was
removed from service, was dropped ~3ft afterwards?

I've even got a TVI950 terminal (good working order!) gathering dust.  Three
times I thought I had a net.deal to sell this, but people keep dropping off
the face of the earth when it comes time to say "OK, Ship it!".  Careful... if
you make me an offer on this, you may be the next person to disappear!

I've got all sorts of other stuff too, some very off-the-wall stuff.
I'd be interested in trading for interesting things.  I'm looking for external
modems (faster than 1200 baud only), VGA color or mono monitors, a UNIX PC or
some flavor of UNIX for a 386 (please no "GET LINUX FOR FREE" messages... I
don't have access to FTP... thanks a bunch, GE), and a few other things.

I will entertain any reasonable offers on these things; my wife keeps telling
me to chuck them, but I just hate to do that.  Reuse is one of the "three R's",
while "trash it" certainly is NOT.
