Question about capcom IO

OldFoo · Post by **OldFoo** » Mon Apr 26, 2010 5:59 am

Does the capcom IO scale down to 15khz? Or is there a switchable output for 31/15khz mode?

I ask this because I plan on putting my naomi in a cab with a 31khz monitor and want to make sure I don't get an IO that only outputs 15khz.

No, It's not a video upscaler. You switch 15K and 31K on your Naomi mobo on the back / filterboard choosing the output you want. You don't need to touch the Capcom i/o for that. The Capcom i/o takes care of audio, video and controls through jamma. Maybe it's a good idea to stick the VGA cable right in the back of you Naomi mobo instead of using the capcom i/o one.

You could stick the VGA cable directly into the NAOMI, but be aware that Arcade monitors often do not support a normal VGA signal. It will display a picture, but very dark/dimmed. The Capcom I/O has an onboard video amplifier that amplifies the signal to the monitor.

True, because the Naomi outputs a standard VGA signal
