Apple IIGS on epay - local pickup in Seattle

Anyone want this? Less than 4 his remaining. Actually I'd love to have someone win it for me and sell it to me at VCFMW, but I've never arranged such a thing so I don't know what to estimate the cost to me would be. (Plus it probably won't stay at $49 for long.) I'd bid on it myself and then

PDP-8 core memory problems.

For some time I have slowly been working on restoring our PDP-8 to operating condition. Here are some notes on the progress: http://www.datormuseum.se/computers/digital-equipment-corporation/pdp-8 It is sort of working now after reforming capacitors in the PSU, adjusting memory currents and

Re: Y Combinator is restoring one of Alan Kay's Xerox Alto machines

This is why Alto restoration with one set of boards is extremely difficult. The machine wasn't designed to be serviced. Almost everything has to work before you can do anything, and there is a very high probability that in the process of bringing it up you will corrupt the disk pack. Hopefully the
