the "zigamorph", yes that is an actual word. I think this was 12-11-0-7-8-9 multi-punch

A co-worker of mine was a student in the late 1970s. The university he attended had a CDC Cyber 170 series super computer. He has the 22 cards of his first Cyber program (written in FORTRAN) on a wall of his cubical.

He hadn't heard the term "zigamorph" before now, but pointed out a 12-11-0-7-8-9 multi-punch card that indicated the end of the "job control" commands, and a double 12-11-0-7-8-9 multi-punch card that indicated end-of-job. Those seem consistent with the definitions of zigamorph I found.

(FWIW, the job control commands identified the job, ran the FORTRAN compiler, then ran the resulting executable. After the 12-11-0-7-8-9 multi-punch card was the FORTRAN source, followed by the double 12-11-0-7-8-9 multi-punch card.)
