I have a couple small color TV's that would suffice, but, I was looking for something more light weight. I have an older Compaq laptop, LTE 5100 Series 2880D, and the LCD screen looks like it would fit with little modification to the case.

The LCD uses a 30pin connector (I am tracking down the schematics for pinouts) for video and an 8 pin (using only 5) for power. What would be involved in using this LCD screen? Could a solution be simply using a video converter like Roy's and matching the ouputs of it to the LCD (of course after changing it's connector to an SVGA standard)? Or would there be more involved? Also, is there an issue of convertig analog to digital or vice versa involved? If someone could point me in the right direction (or tell me it's not a bright idea) on this I'd really appreciate it.

First, please setup a word wrap in your editor and set it to about 72 
characters per line.  I'd have to scroll about 10 feet to the right to 
see the end of the line on some of this, and its only a 15" lappy 
screen.  The reader screen in thunderbird (linux of course) shows it 
wrapped, but the composer screen shows it all on one line.

Second, if it has a 30 pin interface, I'd expect to find the actual 
controller on the motherboard, and unraveling ntsc video enough to drive 
that lcd is going to take some pretty inventive tactics to accomplish. 
I believe you would be, at 50 cents an hour for your time, hundreds of 
dollars ahead of the game to just go buy a more suitable display at 
wallyworld(sub your fav dealer here).  Preferably something with either 
a svga input and use Roys adaptor, or something with an svhs input and 
use that adapter.
