Ok, I found a great link detailing which traces go to which pins courtesy of unbricker.com

unbricker tech page
Using the reference letters from the Undiluted Platinum mod-chip instructions, here is the correspondence to each.

Pin name: UP reference letter
IO7: A
IO5: B
IO4: C
IO6: D
IO3: E
IO0: F
IO1: G
IO2: H
RE: I
CE: J/P (the one you cut)
W/En: K
R/B: L
ALE: M
CLE: N
WP: O
Looking at the pins that are wired up, is it possible for the mod chip to actually re-write the data to the flash rom? I think if the PSP is bricked, then you must always use the flash rom from the mod chip. Does that make sense?
i think it can
"UP" USB -> "UP" Flash
other i don't know :P

1. i haven't U.P.
so i don't know what format they use on FW backup
2. i can't send FW image to anyone
because it is illegal !!
it's so funny
i don't think PSP will work without RAM :P
