Well that certainly makes sense. A bunch of these boards have 4116s.
Seeing as all the 4116-based-6502 designs I've seen are refreshed
through discrete TTL, I guess I don't need to save these. I still
might grab a few, just in case.
I have pulled a few 4116s - probably have to test them in a dynamic
PET or something similar.
