Before the gavel ends the geriatric convention....  Frankfurt Army
High Schools 1967/68 CS class had access to one on-base punch and
got two or three trys per *week* to run on a CDC-160A located down
town.  Wire brush readers weren't too picky so I got extra debug
runs in by carrying blank cards and an Xacto knife, so I could
replace a bad (and typically really terse) fortran statement by
cutting little triangles in a blank.
