The program below is for people who own a machine that runs BBC BASIC (e.g.
BBC Micro, Archimedes, Z88, Macintosh, IBM PC or CP/M machines) sitting next
to an Amiga running F/A-18 Interceptor. The program acts as a codewheel for
the game...have fun !

I wrote a program like this in C the day after I bought the program. Just
thought it would be fun. I decided not to post it however, because the
code wheel is Copyrighted. It seems to me that anything that duplicates
the function or action of the codewheel could be in violation of that
Copyright.
So...beware! The program recently posted may be a legal no-no.
