Based on a simple one line program from the days of basic programing
Comodore 64s, and the ascii characters: "/" (ascii-205) & "\"(ascii-206)
The program randomly picks a number between 0 and 1 and adds it to 205.5.
If its less the 205.99 then the ascii character is a "/"
If its 206.0 or greater then the ascii character is a "\"
Go back to 10 and do it again.
