- After 10 years of the original modchip design for the PSX machines which used the older PIC 12C508, we came across a bunch of un-modded new PS-One machines, and since we had the old source code for the PSX mod-chip, and the original design used the PIC 12C508 chip, which is hard or costly to get these days, and there is tons of the newer 12F629 chips around these days due to the Wii-mod.
We decided to release to the world, our quick and dirty recode of the old Classic 4-wire mod for the PSX using the 12C508 which was originally coded by the famous Old Crow (Scott Rider), and updated it to support the newer 12F629 chip.

Included in this package is the our source code, plus a complied HEX file for programming the 12F629, and a bunch of install diagrams from various sources.
From the ReadMe file: Remember when looking at the install diagrams that this is a classic 4-wire modchip design, so only use the pins marked 1 , 5 , 6 , 8 on the install diagrams.
And on the newer PSX models (9000 and Slim designs), only 3-wires were used with a link wire between 2 points.
I didn't think we would ever need to due another...
