Finalman's Sony PlayStation 2 IDE PCB mod

I DO PLAN TO SELL THESE AT SOME POINT

Either through Ebay if your in Australia or order-able through pcbway.com

------------------------------------------------------------

I am designing afew a printed circuit boards to restore hard drive IDE connector on the rear of v12-v13 slim PlayStation 2's.

Will work on all SCPH-700xx model PS2s. Does not work on SCPH-750xx, SCPH-770xx, SCPH-790xx or SCPH-900xx model PS2s.

The advantage of this doing it this way over soldering SATA \ SD to IDE adapters is that if those adapter fail you have to de-solder the 30 plus adapter wires and then replace the adapter or if using maxdiypower's PS2 HD connect and the adapter board fails you cannot replace it because it is now discontinued.

On my IDE adapter boards, SATA / SD hard drive to IDE adapters will be quickly swap-able.

The disc drive will need to be removed from the PS2. Not really a big deal though cause the HDD will be faster and lasers wear out requiring disassembly of the console to replace.

PROS:
Faster Load Times
SATA HDD, SD to IDE adapters easily swap-able

CONS:
29 Wires require soldering
Requires Housing Modifications
Requires Chassis Modifications
No disc drive
Cannot mount a screen to the PS2 rear.

FOR SALE - COMING SOON

INCLUDED:
PS2 IDE PCB
Enameled Wire
GND wire
2x 3mm bolts
2x 3mm nuts

TUTORIAL

PREPERATION:

If the two pads in the following picture have solder on them, use a de-soldering braid to remove the solder so that the adapter PCB sits perfectly flat on the PS2 motherboard.


MOUNTING:

With the head of a 3mm bolt facing the floor put it through each of the two holes shown in red in the following picture. Then mount the adapter PCB so that all three of it's and the PS2 motherboard  holes line up. Finally install the 3mm nut onto the bolt and tighten.


SOLDERING

Vertical Adapter PCB:
You solder all of the wires directly to their respective IDE pins except for ground pins, for them you only solder a single ground wire to one of the ground pins.

IDE pin number one is denoted by a rectangular pad. The other IDE pins on that same side of the PCB are all odd number pins going from 1 to 39. The IDE pins on the other side of the PCB are all even number pins going from 2 to 40. The odd and even numbered pins increase the further they get from pin 1.


Horizontal Adapter PCB:
You solder all of the wires directly to their respective IDE pins except for ground pins, for them you only solder a single ground wire to one of the ground pins.

IDE pin number one is denoted by a single solid white circle right next to it. The other IDE pins on that same side of the PCB are all odd number pins going from 1 to 39. The IDE pins on the other side of the PCB are all even number pins going from 2 to 40. The odd and even numbered pins increase the further they get from pin 1.


A white circle around a hole means that a wire must pass through that hole to the other side of the PCB, to be soldered to the closest IDE pin where the wire comes out.


PS2
All credit goes to AUTOMAN for discovering the solder points.

NOTE: Rather than soldering to all 8 GND IDE pins my IDE adapter board only requires you to solder to a single GND pin. Use a thicker insulated wire for this.

CASE MODIFICATIONS:

NOTE: After you have finished the mod and when you go to reassemble the PS2 you need to put a ...mm thick washer where you cut off the metal shielding from both top and the bottom side of the motherboard where any of the 6 housing securing screws goes through.

Top Chassis:
You need to cut along the red line at the end of the plastic shown in the next picture.


Before.

After.

Bottom Chassis:

You can choose to either cut or drill depending on your preference.

Drill - Not Recommended.
You need to enlarge two holes with a 3...mm drill shown as red circles in the next picture. 


Then:
  1. Secure the adapter pcb to PS2 motherboard using nuts and bolts.
  2. Solder the wires.
  3. Remove the nuts and bolts securing the adapter pcb.
  4. Hold the adapter pcb in place.
  5. Secure the, bottom chassis, motherboard and adapter pcb together through the two holes you drilled using nuts and bolts.
After.

Cut - Recommended

You need to cut along the red line shown in the next picture.


Before.

After.

Bottom Housing:
You need to cut along the red line shown in the next picture. Leave the thin plastic middle part that runs length-ways in-place. Try and keep it as square as possible. Use a file once you are done to neaten up the area.


Before.

After.

Disable The Eject Mechanism:

3D PRINTED COVER - OPTIONAL

HOW TO MAKE THE HARD DRIVE BOOTABLE

Through the Memory Card:
Install FREEMCBOOT onto a memory card. Then...

With a Modchip:
Install a modchip and set the DEV mode to whatever ELF file you want to boot.

SATA TO IDE HDD ADAPTER

NOTE: The adapter and hdd will require external power to be supplied.

Use an adapter like the one below plugged into the PS2's new ide port.


OR

Use an adapter like the one below with an IDE cable running to the PS2's new ide port.
