Spectre Systems was made up of Brett Bilbrey, Mike Toth and Marion Nelepa. Marion programmed the
sounds for the games. Mike was the manager and took care of business issues. Brett did the game
ICBM ATTACK was an experiment to see if Brett 'could' create a cartridge. He did it in a few months
during his free time in college so it did not take much money. Treasure Cove took a bit more
work... Brett remembers not leaving Marion's house for days at a time...
