If the chips are tested and known working to start with, I probably wouldn't bother with the sockets... If your using un-tested crap from China, then sockets are a must.

Don't forget the bridge/jumper in the bottom 68k footprint that says "flashy clock" and a small bridge between two pins in the RTC footprint to deactivate it.

Yeah JP14 is missing in the BOM.

The RTC I will add before i boot. TBH though i dont really care so long as I get an Atari Logo.

TOS206 and up has the logo, you can only use up to TOS104 on the STFU without a decoder board.
