Jesse aka Tablebeast has done a wonderful thing by posting a link on the Benders list to a collection of Vintage Casio keyboard manuals. They include the owner’s guides for SK-1, SK-5, SK-8, and DM-100.
The SK-1 service manual aka the Bible is also there. Very neat to look at, although I am a little puzzled about the addition of the Tablebeast Modification pages in the PDFs. At this point they seem to contain nothing. At any rate, grab them while you can. Cappy has notified me of an update to his site SailorMouth.org. From what I can tell, circuit bending Casio PT-10 may not be the most rewarding thing to do. Peter B of Ciat-Lonbarde is offering a new kit with design schematics in order to help buy food for the clean up crew working on the fire ravaged Tarantula Hill. This Gameboy case was inspired by the previous GameBoy mods, however it is based around the 40106 Hex Schmitt Trigger not the 4093 Quad trigger, because I ran out. Schematics. 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“.
The mods include a full pitch mod with the use of a TI 74LS624 voltage controlled oscillator. It is also worth noting that a 555 timer circuit would theoretically do the same thing, except that the max frequency of a 555 is about 2Mhz and with the LS624 chip the schematics indicate a range of between 1.5 and 10Mhz with a max of 20Mhz. The downside however is the fact that the LS624 is far more expensive, $2.55 a pop. Still worth every penny considering that the Casio will provide for a full 3 Octave mind melting sound experience, along with longer and grainier recording times. Other mods include a nice line level adapter schematic for the microphone input and a remote trigger option.

Synthacon images courtesy of Audities Foundation Calgary AB, Canada. The Synthacon is a 3 VCO monosynth with a 4 octave 49-note (C-C) keyboard, 26 knobs, 3 trimmers and 43 switches (including 28 color-coded toggle switches). It has thick wooden end pieces and a steep sloped silver (on earlier models) or black control panel above and quite close to the keys.
The Synthacon is said to be quite rare. It is unclear exactly how many were made and sold. We made a few with a keyboard that could play arpeggios of whatever notes were held down. The Synthacon's architecture is divided into ten sections: Keyboard, Sample and Hold, Trigger Generator, Dual Envelope Generator, VCA, Three Mode Filter, Noise Generator, VCO1, VCO2, VCO3. The Keyboard section has controls for Tune, Scale, Portamento (Glissando), Range Select (enables the keyboard to play over an 8 octave range), and pitch bend (a knob, not a wheel). The Noise Generator features a switch for white or pink noise and a knob for level.
