Subject: PDP-8 memory stack

Hello,

I'm new to this list (Sam Ismail suggested I join it), allow me to
introduce myself. I'm an engineer at a startup (FreeGate Corp) and have
been using computers since 1972 when I first laid hands on a PDP-8/e.
Since then I've used a variety of them (still have the boards, docs and
cassette tapes, from a Digital Grourp Z-80 system, my first computer.)

I am the Executive Director for the Society for the Preservation Of
Classic Computers (SPOCC). My current project for the society is to seek
charitable status under section 501(c)(3) of the IRS code.

My current restoration project is a PDP-8/m that is, sadly, without
memory. I've been looking around for a 4K stack for about 1.5 months
now. Progress to date includes buying a stack from Keyways Inc
(www.keyways.com) but having only the Core section work (the sense amps
and xy drivers are not working correctly) These boards are labelled G104
and G227 in DEC flip chip parlance. If you know of anyone who has a
working core stack, I'd be interested to hear about it. I paid Keyways
$75 each (to be refunded since they don't work) for these boards. I've
paid $10/each for "AS-IS" boards. DEC claims they have replacement stock
available at $1800. (a bit much for me...)
