Here are the pinouts (I find the Colour Code useless, as every Mod supplier will solder different Colour Wires)
(Source: http://www.modchip.ca/install/ps/)
Now - Pin 1, is where the LOGO is of an 'M' it seems. It is also usually, where the little in-printed circle next to a pin is on any chip. On my Mod Chip, the wire going to it is RED. Pin 8, is opposite Pin 1 - so the stage goes in a 'U' shape. Top left of the 'U' being Pin 1, and the Top right of the 'U' being Pin 8. Pin 8 on my chip, has a BLACK wire going to it.
Also, the GREEN Wire is used to allow Original Discs to boot. It is reccomened (of course) to install that wire too.
Now you WILL get a black and white screen on non-pal or ntsc games (depending on your console), so you will need to install or buy a color correction chip/circuit.
What is a "color correction chip"?
When playing an NTSC game on a PAL console or vice-versa, you will
generally get a picture without color. Unless you are using a TV with a
SCART connector and an appropriate cable from the PS, are able to process
the signal through a multisystem VCR or have a multisystem TV, the only
way to view these games in color is with a color correction modification.
How does a color correction chip work?
Video in all PS models is provided by the Sony CXA1645 video generator
chip. This chip is capable of generating both PAL and NTSC video, however
the colorburst signal overlaid on the video is generated by a fixed-frequency
crystal oscillator on the mainboard. The color correction mod works by
hard-wiring an alternate frequency colorburst crystal to the CXA1645 chip.
Note that the color correction modification involves either cutting copper
traces on the PS mainboard or unsoldering pins from surface mounted
components. It has the potential of permanently breaking the console if
botched and should only be performed by competent installers. If you have
the capability of getting corrected color by SCART cable or multisystem TV,
you would be better served by using one of those rather than installing a
colormod.
The color correction modification is generally sold in one of two forms,
either as a separate subcircuit from the mod chip (in which case the raw
cost for the parts can be as low as US$0.60, half the cost of the average
blank 12C508 chip) or more increasingly on a well-engineered, professionally
replicated printed circuit board fitted along with a mod chip under the
common name 'colormod/colourmod'. These boards offer an all-in-one solution
as well as some element of additional safety during install and secure mounting
away from any metal components that might short the chip out.
(ORIGINAL MESSAGE)
Hey,
I have a (12C509/P 04 HAG 9838)
(Seen on the Chip like this)
12C509/P
04 HAG
(logo) 9838
Mod Chip for a Sony PlayStation 1 (Known incorrectly as a PSX).
Now. The wiring schematic I got, is for a SCPH-750x Model.
I have looked up online other wiring diagrams, but are all useless because they are colour coded.
Does anyone have this Microcontroller (Mod Chip) installed in a SCPH-5500 Model - or have the Pinouts somewhere?
Thanks.
