PS2 PS2 UART diagrams (EE/PPC/ARCADE)

[El_isra]

I started lookin around for diagrams to make EE SIO on gh-001 PS2...

And I thought it would be a good Idea to have a place where we can post pics and diagrams for EE SIO on models wich dont have leaked service manuals (because on those, its as simple as getting the manual, opening it, look for the word 'TXD' and find the associated pad on B side of motherboard)

GH-001, SCPH-10000 (1.00 Boot ROM)​

Notes:

• I determined this is the EE bottom because of the 3 big black components (i didnt remove the board from the console) because These are on the same layout as the USA release model EE bottom, Wich I saw in an old pic for the EE sio on that model by Marcus brown
• ProtoKernel models (10k and 15k) only have pads for the TXD (transmission, aka: reading from PC) the RXD (reception, aka sending from PC to PS2) has no pad, to get it you must go the kamikaze way, solder it straight to the EE, (only for pro solder skilled people I guess)
• the correct pad was pointed to me by almighty Leo oliveira
  
• ProtoKernel models, just like devkits, use 2.0v for the EE UART unlike the rest of models, wich use 1.8v

PowerPC UART diagrama will be located here

For anyone with knowledge on PS2 hardware:

Information on how to locate the PPC UART on the 79/90k models, where the usual footprint is no longer seen (probably because PPC is merged with EE on those models), will be highly appreciated.

So @pcm720 released FW for ESP32 S3 zero for a PS2 UART Bridge over wifi....
