An IBM 1620 was my first computer, too. Model 1 with automatic divide and indirect addressing. No floating point instructions.

1* were the immediate instructions; 2* were the "storage-to-storage" ones.

My first program was computing Hero's Formula using "FORTRAN with Format". Later we got Load and Go FORTRAN, which saved a lot of trees. But after a few FORTRAN programs, I learned SPS (assembler). One of the coolest tricks was coding loops of different lengths which produced tones in various pitches in a nearby FM radio.

Great machine.
