The following tutorial was swiped from the interwebs while it was still available (back when Tablebeast was a nicer fella); is presented for the sake of posterity and common knowledge; and is not the work of anyone affiliated with Intelligent Machinery, nor any of its imaginary subsidiaries. The first thing you want to do is inspect your Casio SK-1. Make sure it works before you open it up.

My Casio SK-1 and Power Supply
This article first appeared in the August 1987 issue of Keyboard Magazine .
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 generating a video signal. The color of the pixel is determined by the voltage in between 0 ( Black ) and 2 ( White ), so if multiple points on the ROM chip were mixed with various resistor values color images will occur.
The SK1 is known in the circuit bending world as being one of the most interesting and diverse instruments available for modification.
I’ve teamed up with UK bender Paul Parry aka Oceanus to bring you this detailed tutorial on bending the Casio SK1 keyboard.
