The text book is...

Wanous, Wanous and Hughes, "Introduction to Automated Data Processing",
1968, South-Western Publishing Company, Cincinnati, OH.

I've found assignments on setting up the IBM 402 tabulator, and coding
forms for the IBM 1240/1401/1420/1440/1460, among other interesting
goodies. The homework kit contains large fold-out charts of punch
card design sheets, 402 tabulator layout diagrams, sample punch cards
and time cards for assignments, etc.

What I was trying to remember is that this course specifically covers
the "1401 Symbolic Programming System" _and_ IBM 1401 machine language.
E.g...

        Machine Language Instructions
Instruction Operation A Address B Address d-Char Comments
 Address Code
  0378 1 READ A CARD
  0379 M 0009 0230 MOVE CHARACTER
  0388 M 0029 0250 MOVE CHARACTER
  0397 2 WRITE A LINE
  0398 / 0378 0299 CLEAR AND BRANCH

... vs...

        SPS Instructions
Label Operation A Operand B Operand d-Char Comments
REPEAT R READ A CARD
                MCW 0009 0230 MOVE CHAR
                MCW 0029 0250 MOVE CHAR
                W WRITE A LINE
                CS REPEAT 0299 CLEAR AND BRANCH
