August 1966, one of my first software programs.

A page, (nr 3 of 13) from a program to show computer instructions on the machine level, a socalled “trace” program. Was written for the IBM 360 Model 2, which was never released.
On the left the symbolic machine code, on the right the machine code in hexadecimal (handcoded, since there was no compiler/assembler available yet).
