I have this console and I can't identify what mod chip is used. It use 5 wire. Here is a picture: https://postimg.org/image/ockxos3f7/ Because was a poor modding sadly the pin from C718 (right pin) has broken and someone tried to repair it but with no success (green wire). For this mod that pin can be wired in other location than that? Best regards!
It's a glob-top chip of some kind, and I can't find any that use that exact installation. Though I think: red = power white = ground brown = BIOS patch green = data (point 6 on many other chips) purple = not sure, maybe clock? Did find this with a similar chip: http://assemblergames.com/l/threads/strange-ps1-modchip-found-what-is-it.61505/
Mord.Fustang where I can find others point 6 on the board? Can you post a picture? Thanks! Purple is wired to PIN 9 on AL10228 chip if you read bottom-right.
Point 3 and 6 are common with your picture. Power + ground (pins 1 + 8) can be obtained from various points. Maybe someone will chime in here and know about this modchip... maybe guru @TriMesh knows? See also: http://imgur.com/a/N5lKn http://imgur.com/a/52KY2 http://imgur.com/a/6MlbM
As I said in my first post the right side of the SMD capacitor (point 6 in your diagram for ONEchip) is damaged and I can't solder a wire there. The metal part is scraped like in this picture (that's how it looks now the SMD capacitor): https://s13.postimg.org/ardefc347/45006_pt_large.jpg So I need other routes. What function have that SMD capacitor in this model SCPH-102? P.S. I have tried to solder the green wire to the red point in this diagram (https://s12.postimg.org/5az4ztrnh/qb_JJ0_Vw.jpg). Sadly it wasn't working. I have tested the trace with my multimeter from my point red to point 6 and I have continuity. The problem is when the drive is spinning the backup disc it cause some annoying sounds. This was not a problem when the modding was not damaged with point 6... Can my modchip be fried or the laser lens because point 6 was damage or when I tested with point red in my diagram???
The only test I was doing was with Crash Bandicot PAL version original and backup (created with the latest version of CloneCD). Sadly my friend have taken back the original and left me with the backup only so I can't test it anymore with originals. The console was working with both. If this is an important test I will buy one to test my console. But what function have that SMD capacitor? It have something to do with the laser lens? Thanks!
