Apple IIc MockingBoard clone @256byteram

Demonstration of a MockingBoard clone I made for the Apple IIc.

The current setup is ugly. The YM2149 is tacked into the 28 pin socket I've used. I only had one AY-3-8912 but this works. I'll get some more 8912's later.

If there's enough interest I'll have some PCB's made up for it.

$More Television Fractals This is a CCTV multiplexer which can show four individual cameras on a monitor in four quadrants, which I have connected a single camera to, then pointed back at the monitor. The effect is to multiply the image by three (in this case) every time the image goes through the loop. This creates something resembling a fractal. Ive found leaving the fourth quadrant disconnected gives the best results. Strictly speaking, this isnt a completely analogue process, as the multiplexer is a digital device with a frame buffer. The same effect could be done (and has been done) with three monitors. The camera used is a B&W vidicon security camera.$
