CGA Monitor with Dual inputs?????

[koolmoecraig]

Is it possible to hook up a standard arcade monitor(CGA) with two inputs going to it?  Maybe with a switcher of some sort?

I want to be able to use the machine in its dedicated form and then be able to switch it to MAME.

Is this possible in any way?

don't see why not.  Use a AB switch for the RGB G V/H Sync.
