I am a sucker for retro videogames. You may recall from my How I do my computing article that I mentioned I own a PlayStation. I’ve recently replaced the one mentioned in that article with an original SCPH-1002 (PU-8) revision, and I felt like sharing pictures of all the mods that I’ve done to it.

UPDATE: I re-did this mod and improved the efficiency of the modchip wiring. See: better_ps1mods.html

A description is below of the mods that I’ve done. Followed by this are actual photos.

There is also a video, which you can see here:

Alternatively, a direct link to the video is as follows: https://av.vimuser.org/ps1mods/ps1mods.webm

If you have an old gaming system that you would like me to mod, send me an email :) I love any excuse to sit in my lab and tinker with electronics, and I thoroughly enjoy the work!

I have performed the following mods to this system (an SCPH-1002 model, with the high-quality audio DAC and the separate RCA phono jacks for audio):

I really just wanted to show off my work. In addition to the above video, here are pictures:

Composite Sync mod, for proper RGBS output:

Mod for enhanced audio quality:

Mod-chip installation (7-wire MultiMode3 stealth):

Replacement LED (red colour. Resistor is underneath the board):

One more shot of the mod chip, for good measure!

Laser assembly power rail connected to LED via detachable jumper wire (male+female):

System has been re-assembled and its ready to go!

I had a lot of fun building this! I’m soon going to be creating a whole new company (on a new website. it won’t be done through minifree.org) selling these systems pre-modded similarly to the above.
