Ooh... ooh... I'm interested (if you don't want to ship them to Canada).
What's on the paper tape? I'm about to have a serial papertape reader
hooked up to my Linux box (DEC PR/S01) as soon as I can borrow my friend's
20mA<->RS-232 adapter.
If the paper tapes have anything PDP 8 on them I can send you a copy. I have
the PDP-8/S already hooked up to my PC (positive level converters ;-) )
One other thing.... you mentioned you wanted to add more memory to one of
your straight 8s. I have two studies done by the McMaster University on
building core memory expanders for the 8,8/s using straight 8 memory (8/s,8
used the same kinds) and some flip chips. You might want to kill one of your
straight 8s for the memory and ebay/keep the rest of it. I am picking up at
least one straight-8 over the next 3 weeks and if I end up with two (looks
that way) I have the one sold (have to quickly restore it first) and the
other I will butcher for memory for my 8/s. A straight-8 still isn't worth
as much whole as it is in parts.. Ugh.. You might want to think about doing
that as it is nice to keep the same boards/technology in a transistor
computer like that.

NEED
MANY MORE PAPER TAPE TRAYS!
I have two trays, blue things with a clear top and 8 sections about 1x1
inch, 4 or 5 of said sections complete with papertape still in them. $1 &
postage to the first who wants them. -ethan

I remember that particular 8s from when I was an undergraduate. I
did my undergraduate degree at McMaster, at a time when they were
still running PDP 8 machines. That probably ages me :-). At one
point it was a server for a group of DG Novas (I think the
original ones).
