D.I.Y. JAMMA adapter - cool idea and a question
<< < (3/4) > >>

I thought that a Scart TV was the same as an arcade monitor and thus could simple be connected to a JAMMA board without much fuss.. so the voltages aren't the same?  In that case maybe it'd be cheaper just to convert a TV into an arcade monitor with one of those 8liner chassis.   ???

I read at gamesx.com that an easier alternative is to find an old Amiga monitor.

This is true.. I used a Commodore 64/128 monitor for some time.  Just be sure its an RGB monitor.  some of the c64 monitors were just NTSC video.

They are more or less the same if you're using the RGB input on the SCART.... You just have to use a resistor on each of the RGB lines to get the right level or it's too dark. I've got a SCART lead with the resistors inside the plug itself, which works fine.

Now forgive me here, as I'm not a SCART person (live in the USA, where SCART connectors taking RGB are unheard of), but I thought SCART RGB had an implicit DC level, meaning it needed external AC coupling, so there have to be capacitors, not resistors, in the line.  Putting resistors in the line would make it dimmer (due to the input termination).  I know that's what I've found inside all the PS2 SCART cables I've hacked up.
