[Coco] LCD panel

The OKi chip is now obsolete. On rare occasions you might see one 
or two on Ebay. Only place now is to go to the houses that stock old 
and obslete ICs and pay their price and lot quantity. 

I got four HD63C09E's  off of Ebay about 5 months ago and have 
been looking for a few other ICs. 

One thing also that Espon Seiko may have a compatible 
replacement. It doubt it will be an exact but something similar that 
maybe usable. The problem is the monochrome panels are starting 
to go the way of the dinosaurs. Every one wants color panels now. I 
have seen some older LCD color panels on Ebay also. Some are in 
the 6 inch range and will take composite video in.
