I remember reading a similar document for my shop's IBM 4381.

When I started mainframe programming, I was given a pocket-sized 'yellow card' that listed all the machine instructions and arguments. It was invaluable for dump-reading.

My co-workers (who were all older when I started) had similar cards, except in different colors. There were white, pink and green cards, too. You could tell when somebody started programming by the color of their card.

I kept mine, still have it.




The card is now a 116 page booklet aka Reference Summary
