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...) --Chuck
