The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.

Early computer

In 1948, IBM dedicated its "SSEC" in New York City. The Selective Sequence Electronic Calculator handled both data and instructions using electronic circuits made with 13,500 vacuum tubes and 21,000 relays. It occupied three sides of a 30-ft x 60-ft room. On the back wall, three punches and thirty readers provided paper-tape storage. Banks of vacuum tube circuits for card reading and sequence control and 36 paper tape readers comprising the table-lookup section occupied the left wall. Most of the right wall was filled by the electronic arithmetic unit and storage. In the center of the room were card readers, card punches, printers, and the operator's console. It was visible to pedestrians on the sidewalk outside.

God knows

Two rural church deacons who were having a sociable beer in the local tavern when they saw their minister drive by and take a good long look at their pickup trucks parked outside.

One deacon ducked down and said, "I hope the reverend didn't see us or recognize my pickup."

The other replied indifferently, "What difference does it make. God knows we're in here... and he's the only one who counts."

The first deacon countered, "But God won't tell my wife."
