A little update...
Did a redesign since the old version didn't sound that great. A bit scratchy compared to the original. Did GND fill and relocated all the components. The board is 3mm shorter now. All the resistors on the back is more bunched up in the middle. But when trying it out now with MIDI attached to the Atari, the 3,5mm jack is located very stupid. Which I haven't thought about before for some reason. So made a new order for some PCB with the jack facing to the left if attached in the cartridge slot. Or back of the cartridge if you like that analogy better. Otherwise it's more final now.
Pic below is v1.2 on the left and the most recent v1.4 with better sound performance on the right. v1.3 is more or less v1.4 but without gnd fill. I also did a v1.5 with 1206 resistors on the bottom (36 of them) and 1206 on the 2 resistors on top but didn't order that board. Would have been a pain to solder.
