R0...RH - Nineteen tuned-path traces leading over to the main processor. These appear to be address/control lines?
D0...D7 - 8-bit bus that leads from main processor, past button-cell and up from below (south of) the NAND chip.This could be
an 8-bit data bus?
J0...J6 - 7-bit bus emerging from VIAs near button cell, leading around to the north side of the NAND chip. This could be the
re-flashing control lines?
?? - Indicates a pin that is connected by a trace to a VIA beneath the NAND.
!! - Indicates a pin that is connected to a diagonal neighbor by a trace beneath the NAND chip.
