This is a copy of The Numbers Racket CD-ROM, which I prepared back in 1998. I am presenting it here, unedited, for historical purposes. Obviously most if not all of the information is 'out of date' today, but think of it as a snapshot of what the Spy Numbers scene was like in the late 1990s.

Like what you see here? Help support my work by taking a look at my software , and buy something of interest :) It's all available for download before purchase, so you can try it out.

Enjoy!
