A chiptune music player made from the Notacon 8 visitor badge.
Made in one day. The sound is produced by a SN76489 PSG sound chip.
It has three square waves, one noise channel and built-in analog
sound amplifier. The music is a VGM file which was emailed to me

I messed up the breadboard area by lining up IC sockets on one side
leaving no space or time to fit a 3.5Mhz oscillator and two banks
of 32K EEPROMs. I worked around my error by having the
microcontroller generate the PSG clock signal via PWM and moving
the song data (chopped to 25K) into flash memory.  I think
all the extra wires made it look cooler.
