Coin-Operated Computers

Desktop kiosks are controlled by a timer in the coin box. When a Loonie is inserted into the coin box, the keyboard and mouse become activated
and ready for use. Each Loonie gives ten minutes of computer time. When time runs out, the keyboard and mouse become non-responsive. The
information on the computer screen is not lost, just frozen until the keyboard and mouse are activated again by inserting another Loonie.
