Tarr and Morrill knew nothing about computers. So Tarr paid $100 to a computer science student to write a program code designed to match up questionnaire. All the data from the questionnaire had to be transferred to punch cards. The team rented a room-sized computer and took six weeks to produce a match list. Questionnaire participants then received a letter saying who they were match to, along with phone numbers. Most were very pleased. One student got 100 possible matches. One of them was her boyfriend!
