→Device Overview
It has 2 buttons on the PCB: 1 - RESET, reset circuit and IC 2 - Launch monitor diagnostic mode. A 50 pin header provides easy access to most address lines and relevant (to operation) CPU/RAM/Flash lines. This will be convenient to run a logic capture during boot and operation later.
I beeped out the 50 pin connector - thankfully Many pins have multiple connections. Happily; the vias were not tented - this took absolutely ages as it was a long endeavour even with continuity through the vias : ) <gallery>
