You've got a point there.

Yes, and the record layout shows that there were actually two possible card formats: if a 1 was punched in column 1, the card would contain name and address data. If an "x" punch was in column 1, it would contain other fields necessary to generate payroll totals. Interesting. Note that "date hired" is 6 digits which would have been a problem in year 2000.

In the early 70's that's quite possible, but with payroll and accounting and ticket sales, etc., a small computer might have been worthwhile. I think an IBM System 3 would have rented for around $1000/month.
