70s to early 80s for me, though the oldest game i own is from 1969 (Gtb Mibs).

I have a Wms Flash awaiting restoration, might happen in the next five years if im lucky  
was brought home about six months ago and i havent even touched it yet, though i now have the missing coils i needed, i might have to see if i can get it up and running, at least to see what needs doing to it

EDIT: WOW i just realised this was my 1000th post
