Hi, I have several of these:
But I don't have any instructions with them and I don't even know if it is a PS modchip or not. On one side is the well known 12C508/P chip and on the other 59L010T (I can't find any information about it). It has 7 wires. I think it has to be placed over a chip on the PSX board and the wires soldered to specific points. Has anyone seen something like that?
Recently I found an old PS1 SCPH-7025 (PU-22) with no modchip installed. It would be great to have some fun with it and remember the old days. However I don't know if this is a PS1 or PS2 modchip or is it a modchip at all . Maybe I can unsolder and use only the 12C508/P chip but I don't know how it is programmed (classic, stealth or multimod).
I also have some 12C607, 12C508A and 12C509A chips which have been used as modchips but then removed and I have the same problem - I don't know how to connect them because different type of modchips have different diagrams.
