From about 1983 to 1989 (10th grade through college), I worked part-time for CONDUIT
Educational Software. Much of my work was writing "ampersand commands" to extend Applesoft
BASIC for the Apple II. When I left, they gave me this cool T-shirt, which is a cool inside
joke showing how Applesoft would display a function call to a module named LYONS with
a parameter of DAVE.
I believe Steve Hirst masterminded the shirt design.
