Core memory trade?

I'm looking to acquire a core stack (operable - not just to look at)
for a construction project (don't ask - if it works I'll report to
the list later!) By way of trade, I have a genuine S-100 8K core
memory (I forget the manufacturer - the only one made for the S-100
as I recall, though.) If there are interested parties, I'll look it
up and tell you the maker and serial number.

I'd like to trade it for at least a 16K word by 16 bit stack or
plane assembly - just the core - I do not need the electronics.
The core needs to be around a 1 uS (20 to 30 mil?) variety and
also needs to be 3d (X-Y + sense + inhibit) or four-wire
design. I prefer a "stack" or "cube" design, but a planar
layout is ok, too.

For information, the S-100 core is planar and some of the smallest
and fastest core I've seen. It is mounted on a single (fairly
thick) S-100 card, with electronics and I believe it to be in working
order. (I actually *used* one of these types of cards many years
ago on a building HVAC management system that needed "nonvolatility"
but the ability to read/write while operating.) It ran without hitch
on a 4 mhz Z80 Cromemco system. The unit I'm offering to trade came
from a surplus electronics place and I have not (yet) tried it to see
if it works. It was lovingly packed in bubble wrap, so I assume the
original seller thought better than to just toss into the "heap."

Please reply by private email.

Thanks.
