Prototype PCB!


@Freddy Champagne Yes, I said exactly this, an optional "internal cartridge expansion pin header". Surely, it's an optional internal "daugtherboard". But can be used for "real SID" PCB as well, since then probably a single layer/side little PCB is enough as well with a SID socket is enough, and it's extra cheap then rather than re-designing a 6/8 layer main PCB to have SID socket as well. And as a bonus it can be other PCBs as well like with that OPL, if someone wants, but not for everyone, as you also noticed.
