1. Enter the observatory, turn off the lights, sit in the chair, and pull the control panel toward you.
2. Enter "March" as the month and "1978" as the year. The day and time don't matter.
3. Press the button and wait for the constellation to appear in the window. Then change the month from "March" to "November" and press the button again.
4. Two paddles and a ball will appear in the constellation window, allowing you to play pong with the computer. Use the time slider to move your paddle (which is on the left). Have fun!
