"This challenge inspired me to embark on a journey of reverse engineering," he continues. "Initially, I used techniques such as sanding down the original board and cross-referencing the exposed layers with datasheets for components like RAM and memory to define the pinouts. I also relied on original service manuals to guide the process."
Brodesco adds that he has already documented elements of the motherboard design which have previously never been made available publically. The final PS1 system was manufactured in 2006.
