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.
