Stephen Stokes of Aylesbury, Bucks. has sent in a listing similar to Alexander Clark's Sound to Light (AA 19).However, this program works in a different way and is faster because it is written in machine-code. The results are most satisfying if the cassette mput is plugqed into the headphone socket of a music system. Run the program. Setting up the machine-code and inital screen pattern takes a few minutes. Plug the cassette lead into the music system. If nothing happens increase the volume: increasing the volume will result in faster and brighter patterns. Effects are best in a darkened room. Pressing any key will halt the program.
