If you want to reverse engineer the boards in a modern console, you’d better have a lab, a lot of fancy gear, and a good few months to dedicate to the task. The humble PlayStation, on the other hand, is more accessible in this regard. [Lawrence Brode] pulled one apart and started documenting it as part of a grander quest for console understanding.
[Lawrence’s] ultimate goal is to create a portable PlayStation using original hardware. That is, rather than cannibalizing an existing console, he wants to build an original portable from scratch. He needed to understand the PlayStation to recreate it, so he started by analyzing the original hardware.
The first part of [Lawrence’s] quest was to try and reverse engineer the PlayStation motherboard itself. The 1990s console has the benefit of only using a two-layer PCB, meaning it’s far easier to trace out than more modern multi-layer designs. [Lawrence] started with a damaged console, pulled out the motherboard, and stripped off all the components. He then cleaned the board, scanned it, and then sandblasted it to remove the solder mask.
He’s begun the work of tracing out signals, and next on the agenda is to create a new custom PCB that’s compatible with the original PlayStation hardware. You can grab his work via GitHub if you’re interested. [Lawrence] is also excited about the possibilities of grabbing the 24-bit RGB signal heading into the GPU and using it for an HDMI output conversion in the future.
It’s always an exciting time in the PlayStation community; we see lots of great hacks on the regular. If you’re cooking up your own, don’t hesitate to drop us a line!
