    i soldered to a VGA header, and used a VGA extension cable from the PC to the header.

    Problem with that is that VGA extension cables are really horrible and signal quality goes to crap. I'll probably solder some BNCs on later.

    Anyhow, if anyone's in Australia, DSE has PSOne LCDs backorder via their website for less than A$100.. really good.

    anyone whos interested,i also hacked the car adapter 4 the psone to connect it to my power supply.any one tried this?it was my first thought when i saw that it converts 12v to 7.5.hacking the plastic apart is a bear but i finally got it on a molex.now,lol,im afraid to try it cause someone told me that it would be too much drain on my power supply.if anyone has tried this please let me know.

    Ground on VGA goes to ground on PSOne: Pin 8 on PSOne goes to VGA Pins 6,7,8 (Red, Green, Blue grounds).

    You might also need to connect VGA pins 11 and 4 to a ground (VGA Pin 6), as some monitors will detect a display if these are grounded.

    So yeah it'll look like a lot of things connected to pin 6... ^_^

    With regards to the PSOne car adapter (i wish i had one of these), how does it do the voltage regulation? Is it a switchmode regulator (it'll have an inductor inside it: Some brass / copper wire wound around a torus or a bar), or is it just a linear regulator (it'll just have one IC, possibly with a heatsink on it if the designers were being sensible)?

    Better yet, do you have a digital camera or have access to one? A photo of the inside would be nice (especially if the IC print was readable).

    Connect all grounds to VGA Pin 8 [ do something like solder one wire to VGA pin 8, and solder all other grounds to that wire, don't solder everything directly to the pin socket! ].

    You can probably get away with just soldering PSOne common ground (PSOne Pin 8) to just Red ground (VGA Pin 5), but it's probably best to ground everything to a common point.
