Yeah, that's what I was thinking...use the laptop as it is, and talk thru the serial port to the "host" mame PC. I was just hoping that someone might know an easy way of getting mame (mame32) to talk over a serial line, specifically for marquee displaying.

Thanks for the reply...

: If you want to use a laptop LCD be ready to spend some big bucks. Finding a laptop screen is easy, check ebay- they go for $20-$50. Actually using the screen is another story. To use the LCD to display images from your computer you will need an LCD controller PCI card. You can find cards like these at www.earthlcd.com, but none of them are less than $200. So to you're looking at roughly $250 to use a junk laptop LCD. It would probably be easier if you used an old working laptop. You could store the images on the laptop and possibly setup some remote control of it through ethernet or whatnot. My only concern would be that the laptop LCD wouldn't have enough brightness- especially if it's an older passive LCD. Good luck though, if you can get it to work it is sure to be an amazing touch.
