Installation of the REI Colormod Module
for a PU8 PlayStation Console
(Model SCPH-3000, SCPH-5000, late SCPH-100x)

Making the connections between the Colormod Module and the PSX PC board

Wire 5 -> Data (mod)

Connected just above an 8-pin 2903 chip on the underside of the board about 4cm below and 5cm to the left of the corner of the board closest to the external power cable socket.

Wire 7 -> Gate (mod)

Just below that same chip

Wire 1 -> Vdd (mod)

Wire 3 -> Ground (mod, color)

Wire 9 -> Freq (color)

Locate the CXA1645 video generator chip. It is located on the top side of the mainboard just above and slightly to the left of the "PU-8" marking in the solder mask. Pin #1 of this chip will have a small dot inset into the plastic of the chip (in the upper right if viewing your mainboard from the orientation it would be in when installed in the case - the following image shows the chip inverted 180 degrees from that position)


(this picture representative only and may not match your mainboard exactly)
Step 1
Connect wire #1 to pin #12 of the CXA1645.
Step 2
Connect wire #3 to pin #1 of the CXA1645.
Step 3
Lift pin #6 of the CXA1645 off the PC board or cut the trace coming from that pin. Connect pin #6 to wire #9.
Step 4
Lift pin #7 of the CXA1645 off the PC board or cut the trace coming from that pin.

Mount the Colormod board on the top plate of the PS by use of a ~5mm spacer. Then reverse the disassembly instructions, remembering to connect the wiring harness to the module before replacing the outer cover on the PS unit.
