Hey @_The Doctor__, I was working on cleaning up a 130XE this past week that was previously upgraded to 320K BITD, and I came upon this area of the PCB. These 'piggybacked' resistors sure look like the keyboard mod you describe above. Any idea which keys these three resistors here would be helping? I'm guessing start/select/option, as the reset key seems ever so slightly less responsive...
