Here is a link that Roger sent me a while ago. Its a website by Frans Samshuijzen with detailed descriptions of some mods that he did to a set of Casio SK-1 keyboards appropriately titled: “Casio Twins“.

Benthack blog recently suggested some variations on the previously posted SK-1 Video out schematic. Different ROM IC pins yield some nice results as seen in this video. Nice work!
Gijs of Geiskes.nl has just sent me some information on their recent experiments with patching signals from an Casio SK-1′s ROM chip to a video monitor. The circuit is simply a diode to prevent the back flow of current and a resistor to drop the +5 Volt logic gate to a +2 Volt required for […]

The Gijs’ SK-1 device has bends patched to various places around the stationary contact wheel and while the arm twists around at various revolution rates glitches are […]
