Turn a PC into a Radio Transmitter (with just a piece of wire) HD

Mario + Floppy + Radio Waves By connecting a length of wire to the headphone jack, you can use your PC as a crude radio transmitter, so you can listen to your favourite music outside on a sunny day. Routine written to the boot sector of the floppy. The Programmable Interval (PIT) is a device used on most x86 computers for interrupts and for setting a square wave frequency for the internal buzzer (or speaker/audio out). By setting it to its maximum frequency (1.193182 MHz / 2 = 596.591kHz) and turning on/off using timed delay loops, we can create an AM radio signal through the headphone jack. A length of wire connected to this acts as an antenna - in this instance a longer length increases the range. 597kHz falls in the medium wave band and can be received using a normal MW radio. (inspired in part by the use of AM EMI to make music on the old Altair 8800: https://www.youtube.com/watch?v=wDqArTme4B8 ).
