    Good one. How come I can't get my scanner to do that?
    I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

      Heh. Slick trick. That sort of hack is traditional and as old as computing. When I attended UC Berkeley I studied computer science. We had access to the CDC 6400 main frame supercomputer. For printed output it had a high speed chain line printer. Someone had programmed it to play a nice march by striking different letters simultaneously. They had also discovered how to program the CPU to emit different frequencies of RFI to play music on a transistor radio sitting close to it.

        Think it was the old sinclair computers that they used rfi to produce sound on the television/monitor, the computer didn't have a sound system

        Also, there were a few programs that would play music on the old 5.25 (1541?) commodore drives, using the mechanical actions of the drive itself.

        Always thought it was pretty cool.
