Subject: MARCH's Straight 8 restoration notes
The RICM PDP-12 thread made me realize that I (nor I think David
Gesswein) ever posted our PDP-8 notes here. (We did post a link to the
Youtube video of the ceremony at VCF East.)
Anyway, here are David's notes:
http://www.pdp8.net/shows/vcfe15/slides/PDP-8_Restoration.html and also
his exhibit notes here: http://www.pdp8.net/shows/vcfe15/vcfe15.shtml.
Evan,
It is nice to see documented proof that we are not the only people crazy
enough to attempt a restoration of a machine in that condition. The TU20
tape drive that came with the PDP-9 also had a unauthorized mouse upgrade,
and several transistors fell off the flip-chips when we touched them. They
were Germanium transistors so getting replacements was a challenge.
