I did a quick check out of the PDP-8. Everything in memory seemed to be
corrupted but when I reloaded everything seemed to work ok except the
deposit and examine switches are a little flaky. They are usable but
you need to watch out for it incrementing by more than one and go back
and fix the address. I should be able to clean them at a future workshop.

I left it with the accumulator light pattern program at 100 octal and the
punch block letters on paper tape at 200 octal. The punch demo may be another
thing visitors can do and take home if we have more paper tape.

There is a notebook with the machine with operating instructions and I can
walk people through operating it if anyone is interested.

I would recommend turning off the power strip I left tucked under the right
rear if the backplanes are open to make sure nobody can reach in and find
exposed AC. Don't turn it on without closing the backplanes for the same
reason. There is lots of exposed AC when the machine is on. Closing also helps 
the cooling of the power supply.
