Yes !!! it took me some time .. but today I created the cable Big smile and now I have SymbOS 2.1 running in full color on the PowerGraph Big smile

Are there other dudes that tried to use SymbOS 2.1 already with this nice v9990 :D ?

Great work !

Could you please post the exact connections you've used between the 15-pin connector and the SCART ?

I'd like to make myself one, to use the V9990 on my Panasonic Turbo-R ST Smile

Thanks !

And beside that cable , I created also a cable for this computer today Big smile but that seems a bit off- topic Big smile

Before the MSX .. this was my 'daddy's first home computer' .. so I learn basic on it ;)

"In full color"? I think it's still only 16 colors, right? Tongue

Is that cable for the TI simple to make? Please post the pinout for that if you want?

It was my first real computer also, and still have one stored...

Yes very simple. I used this link TI video cable

Do you have the PAL model or NTSC ? The one I own is from the US so for color output i used a television that's able to support NTSC.

I have a pal version. It is indeed very easy. I'm gonna make one, but my solderingskills are nonexistent... But this one's so easy, even I can't screw it up...

Be aware that 1 pin has 12V output ..it's not documented but I noticed. I think to power up the TV modulator which is normally connected on that port
