Title: Sanyo 20-EZ Monitor Advice
Post by: wirikidor on September 25, 2014, 08:07:46 pm
So I picked up this old Donky Kong that's got a Sanyo 20-EZ monitor in it. It looks great, no burn in... but I have read some conflicting things on different websites about connecting a PC to this monitor. Has anyone out there successful used this monitor for a MAME cabinet? If so what did it take any type of converter card?

Also for you purists out there, I have no intentions of modifying this cabinet, adding buttons, changing anything, etc.  I only want to be able to play a few vertical games like PacMan and DigDug as well as DK.

Also, here's some pictures http://imgur.com/a/qF0mR (http://imgur.com/a/qF0mR)

What video inverter?

Nintendo games used negative video. basically everything was backwards to how most if not all other games video works. basically a regular jamma board hooked up to a sanyo ez without an inverter would result in black being white and white being black.

I'm not sure if the programs such as soft 15k can account for this or not but I know the inverter is needed for regular jamma boards and what not.

here is some info on the inverter.

all the ez chassis i have worked on you can bypass the inverter by moving a connector on the inverter pcb-which is mounted slightly to the right and behind the flyback cage

But the inverter is an added part, correct?
  I've worked on 20ez' in donkey kongs and Mario bros that didn't have the inverter board,
Or so I thought.
