Vintage Simmons Drums (UK) Users Group

I know someone working on it. A guy able to dig in & sort out much more complicated systems like Fairlight PPG etc ...
But not that simple as it seems apparently.
He won't communicate about it, till it's not finished & working.
There are a few issues to solve ^^

I have looked for one but can't find one. I have searched for the schematic for it but again cant find it. So, if someone has the schematic or owns a cartridge and can get some good pictures of the pcb (top and bottom from directly above) I could reverse engineer it. Due to my work, I have the ability to do short runs and prototypes from my home workshop so it would be possible to do a run of them for people that may be interested.
