Midway Arcade Cabinet by Big Electronic Games
jbserra:
It requires an RCA input. There are RCAs out on the "computer". You would need an LCD with RCA input. You could always run sound to speakers if it's a monitor with a single video RCA input.
There is a video switch box inside the cabinet for the TV, so you could switch the video between sources, but that doesn't switch the controls. You can probably wire your pi to the controls simultaneous to the existing computer and just power up one unit or the other and use the switch box for video. If your LCD support HDMI, then you would switch inputs on the LCD.
If you don't want the old game unit, let me know. I might be interested as a spare.

My son in law just dropped one of these off to me that he has had since it was new.
Monitor h-hold was out, so I replaced the cap and got everything up and running.
I checked the monitor while it was out using a commodore 64, and it looked good.. really good.
But when I got it back in the game, every thing was dark and smeary, with horrible colors.
So I removed the cart assembly and tried it on different monitors, and it's color is awful.. Black and white on most lcds (if they sync at all),
Look at it on a scope, the colorburst signal is very low. Has anybody ever figured out a hardware fix to get good video out of these things?
Thanks.

What do you mean, "it's color is awful"? Do you mean it doesn't look like the original game, it's faded, wrong color selection or what? It does look like some folks had issues with getting LCDs to display properly (see above posts). The original tube looked fine when I got mine, but it was dark. I found my brightness was at 50%. Cranked it up to 100% and image looked just fine. I now run a 20" Sony tv in it and it has colors and I think it looks decent. If you want to use the original cartridge, just grab a free/cheap tube off Craigslist and off you go!

What I mean is that the games are too dark, and colors are wayyyyy off
But the same TV using a different input device. (I.e. a commodore 64.) is displaying all the colors correctly, brightness and contrast are good. And looking at the output of the original game board (cart),
it's a very weak signal.
Hooking the board up to one of my Sony PVMs, same dark screen with very muted colors. Like everything is muted pastels.
Robotron has never looked so bad, and bubbles is basically unplayable (Player character is lost in the background except for the eyes and smile.)
Another example, in robotron the hulks are grey. And I still don't think I've see a bright red out of this thing while on the PVM.
Joust logo is pale yellow with orange highlights.
Here's the title screen for splat

Yeah, I'm not sure. Maybe there is something with the board. There isn't much red (as you mentioned), but there is some. Here's a couple of screens:
