Good news - Lyle called me 11/08/13 and he now has his PDP8S fully functional. Follow up email indicated continued work - replacing a few burned out panel lamps. Great work Lyle sure good to know the 50 year old system is now executing programs.

I was chatting with Michael from the RICM and was about to ask him to
watch the video on your website of you finding and opening the box
containing the PDP-8/S you sold me. But I couldn't find it on your
website. - (Here is the link to video- Dave)
BTW: Since we last chatted my PDP-8/S has been up and running most of
the time. A couple of weeks ago, another transistor went out - and
memory began to fail. I found and replaced it - and now it's working
100% again. So far I've replaced a total of about 32 transistors and
over a dozen diodes.
I recently went through CPU and memory timings in great detail - and
now they meet all of DEC's specifications.
My 8/S passes all DEC diagnostics - and runs FOCAL w/o a hitch.
Bob build a cool I/O interface for the 8/S (and made one for me, too)
that emulates a TTY, high speed paper tape (partial), A->D, D->A and
incremental plotter. He does the hardware and I'm in the process of
modifying the drivers in FOCAL to support all of the above ;)
I hope all is well with you and Gaynell!
