So, we're at the end folks. The final fixes on this console were quite tricky to figure out because of assumptions I had made about the new old stock CXP Sony ram I had purchased from eBay and installed years earlier. the LSPC2-A2 chip is now completely functional, so its just a matter of debugging the ram issues.
Hopefully you can learn from my mistakes.
