"This was an nice DIY project. The preset Teisco S100P has a really interesting internal structure (VCO, LP VCF, 2x EG, 3x LFO, PWM, formant filter (which is originally used in only one preset:), two HPF filters... plus spring reverb, aftertouch, analog flanger, which is unusual for a small monosynth. So I modified one preset to make it fully editable, see the panel on the right. In addition, a CV/Gate input has been added. It sounds great, dense, meaty.

Technically perfect, visually see photo - lots of 3D printed parts, including potentiometer caps, etc. The added editing panel can be easily removed (and the Teisco logo put back), but that would definitely be a shame.

Personal pickup possible in Prague (CZ) or Essen (DE)."

"This circuit board came in with one of the many Rhodes Chromas we have bought, restored and resold (we’re finishing another at the moment which we will list soon). It appears to be part of a rare chroma apple ii computer interface that allowed the apple ii computer with sequencing and patch editing software to control a Rhodes Chroma. The Rhodes Chroma website, which is probably the best vintage synth support website we’ve ever come across, has an article on this interface. You can find it by googling rhodes chroma apple computer card. It appears as though there were other components to this interface that we didn’t get with it (converter box, software and possibly more), and we don’t have an apple II computer, so we haven’t tested this item and are selling it as-is as a collectors item, or for parts to possibly get a full system working (with no guarantees)."

"Synthesizer module equivalent of the Roland Alpha Juno-1 and Alpha Juno-2 keyboards. This unit has been professionally refurbished, unlike most. The internal battery was replaced and what we believe to be the original factory patches were reloaded. All synthesizer parameters were systematically tested on all voices and are working as they should."
