::: So this happened : The Fabled Simmons SDS 6 In the Wild :::
Today in the shop i have a Simmons SDS 6. This one is serial number 105. Seeing as there was only 109 of these ever made i'd say this is practically a Chupacabra! It was shipped to the US from Europe so the power supply had to be changed to see 110 volts. The transformer has two primary coils that were hooked up in series for European voltage but once they are changed to a parallel configuration it should be fine!
The manual also says to use a 1A fuse in the US.

There's not much info on these in the world ( google ). I have the manual and schematic here with this one which is helpful. The circuit boards are riddled with modifications that were probably done on the production line. This one doesn't have MIDI but supposedly a few had been updated to support it. There's a few videos on youtube that show off how utterly awesome this is to program and watch:
