What was the computer they used in Weird Science?
Didn't they use something
 unusual in Ferris Buhler's Day Off(did I spell his last name correctly?) 
 I'm nearly certain Ferris had an IBM PC of some sort, and that the
 computer in Weird Science was a Commodore, of the VIC-20 or C=64 variety. 
 
Yeah, Ferris had a PC.
