I understand it does not amplify anything but it it mixes the PSG, PPI and 2 slots into MIXO and it does look like it also includes a low pass filter (but I am not entirely sure).

I am not a specialist in audio circuits, so I made a clone of the original circuit. If anyone has ideas on how to improve the audio, I could make a few experiments.

How much would each plate cost once assembled?

I don't have plans to assemble and sell these boards. I will make a few for myself in order to repair my own computers or computers of my friends. Maybe I will sell a few DIY kits to cover my expenses, but this is not decided yet.

@Stt1: noted

The boards have arrived. The parts are on the way. The total cost of the project for me so far is around 69$.
