In this thread, I describe my journey of making a simple plug at home (using off-the-shelf parts) that fits the original Sony PlayStation's parallel expansion port.
As of this time, I have failed quite badly.

So, I fixed the 5 broken pins. But guess what? Another 5 pins (which worked completely fine before) started to act up! So I even fixed those, but some still remained broken and some other unrelated pin all of a sudden started bending its matching pin inside the console's connector! Words cannot d...

Alright, so I've modified the PCB by removing the now unnecessary power regulator, and I've also added a header for controlling the chip enable line coming out of the PlayStation's CPU with a simple switch, in case you just want to disable the ROM without removing the cart from the console, since...

It's coming closer, I promise. I'll take my PlayStation back apart next week and continue working on the connector and getting it finally working. In the meantime, I found some Action Replay schematic to see how the ROM is hooked up to the PlayStation's parallel port, and what struck me as being...

Finally, another update to my project! I haven't fixed any of the broken the pins yet (I have reassembled the console back together), as I am currently tackling another problem: finding a working ROM and burning data to it. Now, as luck would have it, I found at home an old SST29EE020 (in the PL...

Alright, so I did the first continuity check and only 4 out of the total 30 pins were bad (one data pin and 3 address pins), which is by no means perfect (the connector won't work properly when a single pin is bad), but it's way better than I was expecting. Upon looking inside my connector, yeah,...

Well that's definitely not good. There are 3 pins that did this: one in the front (in the red circle), one in the middle and one all the way in the back of the connector (I figured this out by looking at the mating part of the connector – I saw 3 pins pushed in). There is perhaps a reason w...

Ladies and gentlemen, She's in. Tomorrow (or even today, if I make it), I'll take the console apart and test the continuity (and detect potential shorts) between the pins to make sure it's making full contact. I've hooked up the power lines, chip select, read enable, the first 8 bits of the...

On the previous post, MottZilla asked me whether I plan to create a PCB-mount version of this connector. First of all, thank you so much for expressing interest in my little project. But to answer your question: currently, I intend to solder directly to the connector just to prove that it works....

First of all, thank you to everyone for giving me advice. About the Cybdyn Systems deal: they offered to sell me 4 connectors for $30 AUD, so around $21.53 USD ? $5.38 USD per connector. Actually very reasonable, considering that these are purpose-made connectors. However, I did not go through ...

So, the fine folks over at Cybdyn Systems have actually responded to my request: Uh-oh. Well, that immediately tells me that the total price will be in the human organ territory, and since I am a broke student (who would really like to keep his kidneys intact, thank you very much), that probab...
