INSTALLATION
INSTRUCTIONS
The guide here shows the processes of installing an mod-chip
in an
older grey Playstation as for the newer PSOne the steps are simillar but
in general easier.
Removal of
the PSX cover
- Be sure that there
is no disk inside the PSX and anything is plugged into the ports!
- Turn unit upside down and remove the black screws. (6 pcs)
- Turn unit right side up, and lift off the cover. Make sure
that you also save the parallel port connector cover
in a safe place.
Removal of
the CD drive
- Pull the flexible
orange cable straight up to disconnect it from the motherboard.
- Disconnect the power-connector (the other cable from the CD
drive) by pulling it straight up. Be careful,
itīs easy to break!
- Lift off the CD drive and put it to a save place.
Removal of
the Heavy Metal Bracket
- Disconnect the
power cable from the motherboard. You must disconnect this cable
from both end, as it
is fixed to the heavy metal bracket.(at the SCPH
750x)
- Also disconnect the ribbon cable from the motherboard by pulling
it straight up.
- Remove the 4 screws holding the metal bracket.
- Lift off the bracket.
Removal of
the Metal Shield (SCPH 700x , SCPH 750x)
- To remove the metal
shield you have to resolder 8 pads, where the shield is fixed.
Wiring the
Chip to the Playstation
- If you have a model SCPH 550x you have to remove the lasting
screws to remove the motherboard
from the housing, because all soldering-points are at
the bottom (except point "2" or "3").
- Make sure that only a very small amount (about 1mm) of bare
wire extends past the insulation on the
wires that you must attach to the Playstation.
(In case that you have a model SCPH 550x turn the Motherboard
up side down)
(In case you install a "classic" modchip into the model
SCPH 750x or 900x the green wire is just
needed as link-wire with no connection to the chip.
You must cut the green wire!). Donīt make the link wire
longer as needed,
- Solder the wires beginning at point "1"(red) and "8"(blue)
next "4", "5", "6", "7", and at least "2" or "3"(brown).
Temporary Re-Assembly
You have to reassembly
the PSX temporary to ensure that the chip is operating properly.
- Check again all
connections
- Resolder the metal shield.
- Put the large metal bracket back to its original place. As
you do this , pass the wires attached to the chip
through the small gap between the metal bracket and the
metal shield on the bottom of the motherboard.
- Place the chip in the small indentation at the front-right
corner of the PSX.
- For now donīt attach any screws.
- Reattach the cables from the powersource and the Controller
connector.
- Set the CD drive back to its place at reattach the two cables.
- Put the main cover onto its place.
Testing
- Insert a real,
non-pirated game. Turn the unit on and ensure that the PSX boots
the game.
This happens if the white Sony-Logo turns into the black
Playstation-Logo.
- Insert a real, non-pirated imported game. Turn the unit on
and ensure that the PSX boots the game.
- Do this also to your other cds. :-)
- If there are any problems (for example the disk spins at a
very high speed maybe the laser has to be
adjusted see

Final Reassembly
- Simply go to the
"reassembly" steps, this time screwing everything in.
- Repeat the "testing" steps.
