Hi all:

A few years ago a bought the Voicing Board & Volume Board of a TR-707. The boards where fully functional, I could trigger the sounds with MIDI, but I couldn't use the sequencer as it didn't have the Switch Board.

I built the Switch Board and a case to hold all. I also added some mods to the analogue circuits and a big EPROM to have a total of 8 banks of sounds that I can select from 3 switches. I based the EPROM mod in the mod that Thierry Eppherre did (Thank You Thierry).

Here is a video (comments in spanish):
