HP HP-67 - Running a Prerecorded Program

Meet the HP-67 17
As you will see, these same keystrokes can be used to write a
program for the HP-67 that will solve for the area of any sphere.
But first let’s look at a prerecorded program, one of the fifteen
in the Standard Pac shipped with your calculator.
Running a Prerecorded Program
The Standard Pac shipped with your calculator contains 15 prere-
corded magnetic cards, and each card contains a program. By using
cards from the Standard Pac (or from any of the optional application
pacs, available in areas like finance, statistics, mathematics, engi-
neering, or medicine) you can use your HP-67 to perform extremely
complex calculations just by following the cookbook-style directions
in each pac. Let’s try running one of these programs now.
1. Select the Calendar Functions program from the Standard Pac
card case.

2. Ensure that the W/PRGM-RUN switch werem JiMIruN is
set to RUN.
3. Insert side 1 of the Calendar Functions card, printed side up,
into the card reader slot on the right of the calculator as shown.
When the card is partially into the slot, a motor engages and
passes the card through the calculator and out a similiar slot
on the left of the calculator. Let the card move freely.
