On [[CECH-25xx]]/[[JSD-001]] the pinout of the PCI connector seems to differ from what is published in frontpage. See [https://www.psdevwiki.com/ps3/images/5/50/PCI_connector_JSD-001_SB_and_SC_UART.jpg this photo], and the comment about the noralizer schematic [[Syscon_Hardware#Syscon_UART|here]]
On [[CECH-25xx]]/[[JSD-001]] the pins 78 and 79 of the "80-pin PCI connector" are directly connected to syscon [[SW2-303]] UART pins 78 and 79. See [https://www.psx-place.com/threads/syscon-firmware-key-is-now-public-release-by-zecoxao-what-does-it-mean.26148/page-17#post-273673]
*[[PCI]] pin 4 directly connected with [[SW2-303]] pin 79 (SC_TxD)
*[[PCI]] pin 6 directly connected with [[SW2-303]] pin 78 (SC_RxD)
*[[PCI]] pin 75 directly connected with [[South Bridge]] (unknown BGA pad number, UART SB_RxD)
*[[PCI]] pin 77 directly connected with [[South Bridge]] (unknown BGA pad number, UART SB_TxD)
