Playstation one компонентный кабель
Post by CosmoGuy » February 2nd, 2014, 4:48 am
I was wondering today, why is there no possibility, to plug ps1 via component cable which is ok for ps2 and ps3?
Why is there so big problem to show image through it with ps1?
Regards .
Edit: sneaking on the internet i found this nice little thing: http://www.amibay.com/showthread.php?t=40575 Does someone of you guys have this? Pretty rare thing i guess.

Because PS1 can’t produce YPbPr component signal. It does Composite (CVBS), S-Video and RGB.
On PS2 R, G and B pins double for component and you have to manually toggle between RGB and YPbPr (in BIOS).
In that configuration G pin (now Y) outputs sync while in RGB mode (which is same as in PS1) it doesn’t.
If you were to modify PS1 to output sync on green you could use that cable with a SoG (Sync on Green) RGB monitor.

I have something pretty similar to that, but I would be sceptical of the seller listing that one as «official».
The unit I have plugs into the AV port and also takes its power from the memory card slot.
The picture quality isn’t great but the main problem is the refresh rate. Most TFT monitors I plug it into complain about the sync being out of range. The picture quality isn’t good either, the colours are a bit washed out and I get a much better picture by using a decently quality RGB start lead on my TV over that via the VGA port.

It supports RGB (japanese SCART) too.
RGB totally rulez! 
Back in PSX era, I used to use S-Video all the time.

0.7V, where as the cathodes require a bit of a higher voltage. The cathode voltages depend on the TV, so use a voltmeter to check and try to match them with the amplifier. It will work on a lower voltage, but the picture will be dim. It’s best to add potentiometers to the back of the guns so you can fine tune them according to your likeliness.
As for the sync, just feed the C-Sync signal to the RF, Video 1 and Video 2 pins on the driver IC. That way, as soon as you turn the TV on, no matter what channel it is on, it will always display your picture. This mod will now render the TV as a dedicated RGB TV only, so unless you add a bunch or switches or make yourself a circuit that will use something like an ATMEGA328 with mosfets to control everything via a single button, it’s stuck like that.
I’ve also found you can drive the on screen display chip (aka «Jungle IC»), but most of them use digital RGB and not analog RGB, so you wont see gradients for example.
I have a really big and old NEC CRT that I will try to get working using the direct gun driving method. I will start a worklog so that others can see how to do it.
