EDP Gnat Synthesizer Schematics

Tim Stinchcombe reverse engineered the EDP Gnat and has posted the schematics online.

"I originally bought one of these out of idle curiosity - having read all about the Wasp and its use of digital inverters in the analogue section, I couldn't resist buying a Gnat (a 'Special' in fact) when the opportunity arose. It was sold as none-working, and after replacing a few chips, I got it working. On acquiring a Wasp, and then a second Gnat, it became clear there were differences between both the Gnat and the Wasp, and between the Gnats themselves. Nothing for it to but to reverse-engineer the whole thing, and have a look-see myself! The schematics are only hand-drawn, and I make absolutely no guarantees to their correctness whatsoever (more notes follow)"
