I would appreciate some advice...
First, there were many types of PDP-8 made, so recording the
part numbers for the buyers is important to their making decision
to buy. Certainly apply this to the "logic board" category.
What are the codes on them?
Typically there is a one-letter,four-digits code printed on the top.
For other parts, the number strings will be a little harder to find,
but important. Every thing you identify will increase in value
because it decreases the time and money the buyer could waste.
From the nameplates it seems to have had a
serial number in the late 700's.
Good, keep recording these numbers.
