JAMMA compatible MAME cabinet : Feedback please

Pages: << < (2/2)

ma70ltd:

Thanks for the input CheffoJeffo.

Maybe I was a bit unclear in my first post.

I'm actually building a Cabinet from scratch - primarily to run MAME, but I also want to add the JAMMA compatibility, hence why I am running a TV - and note that arcade monitors are hard to come by second hand in OZ, otherwise I would have gone the arcade monitor route.

And as for sound, I plan on using an amplified sound card, that way it should be fine to run sound for both the MAME machine and the game PCB's.

You're wrong. You're mixing up vertical and horizontal refresh rates.

He's not alone ... I  goofed (in my head at least) thinking that TV had horizontal scan rate of 30 kHz instead of 15.75 k
Hz ..

ma70ltd: I get it now ... will be intrigued to see how it works out ... wonder what kinds of resolution issues you'll run into. Keep us updated.

Cheers.

You're right, My mistake.
But that shouldn't affect my project plan.
I should be fine running the video feed from the J-PAC/JAMMA harness and running it through the RGB-> PAL video convertor - as per Jeffo's bit of advice

I guess in the end it comes down to : I either have to buy an arcade VGA card or just build an S-Video double adapter. I think the latter will be cheaper for me.

Thanks Jeffo, Ray and Bob for your feedback :) Will keep you all posted
