Perfect as always, rama3!

Picked up an old unit; I think the CD drive is near-enough shot, but I can always replace that at some point will let you know how it goes!

I've been searching everywhere for PU-8 Mechacon placements/pinouts without success for a SCPH-1000 series install . Does anyone know where I can find some specs/service diagrams so I can work out the SQCK & SUBQ placements?

Sorry for the lack of updates. Reasons follow: Firstly, lack of time. As always! Secondly, I foolishly traded most of my PlayStation games many years ago, and it has taken several weeks of scouting around retro stores and eBay to get some titles for proper testing. I *did* create a wiring diagram fo...

Glad I could help. But I've got to disappoint you with the re-wiring a bit, I'm afraid :p The WFCK signal offers some advantages I want to use, so that'll be one extra pin / wire. On older boards, I'd also like to use the gate wire again. It is easier to support and well tested. I added the WFCK wi...

Oh god, what were they thinking! :lol: That's exactly what I thought! Is that "Pin 8" there, the one floating off the board, is that connected to the serial receive LED / RXLED? Well, I needed that, thank you very much Arduino guys. From my limited research it appears that you can remove ...

Might be. Unfortunately, SQCK isn't available on the top side as a test point or even a via. You could do it like this for top side mount: https://i.imgur.com/Ign8tPW.jpg Alternatively, go for the chip on the backside (ring out the connections) and only route the data wire to the other side, throug...

Would I be correct in thinking these are the correct pins (front and back) for a PU-23 board?
