I helped a friend of mine pick up a load of surplus stuff today and one
of the items that I got was a bag of keyboard overlays that came from
Tektronix. The Tektronix tag on the bag is dated 1973 says that they're for
a PDP-11! The overlays appear to be for a numeric pad or something similar.
They have cutouts for four rows with four keys in each row. The overlays
are all marked as "User Definable" so the key positions are unmarked except
for Cont, Reset and CPU Busy in the last three positions in the bottom row.
There are four orange color overlays, five yellow overlays and five blue
overlays in the package. Does anyone know what these are four????
