Hi, what is the difference between PSone SCPH-102A and SCPH-102C ?
Do they have different diagram to mod the ONEchip (pic 12c508) on own motherboard ?
I have seen that FatCat proposes two different diagrams (with 8 wires), I think the first diagram is for SCPH-102A
In these the pin 8 is linked on different points
Difference between SCPH-102A and SCPH-102C?

I think it just comes down to the chip itself and the code (binary) that is programmed, because each GPIO pin on a PIC MCU can be changed around to be whatever, so they probably had many different revisions for the binary that was flashed.
As for revision A versus C, I can't tell you. It might just be a different BIOS revision or some minor tweak on the PCB.

Ok so the difference is just about the chips on the motherboard (hardware)
Does scph-102c has to be modded with a different diagram than scph-102a's?
