[Coco] Disto 1MB or 2MB upgrade

[Chuck Youse]

Does anyone have one of these the want to part with?  I'm pimping out
one of my Coco systems to serve as my main dev box, and I'd like to bump
a past the 512K mark, as I'll probably be hammering this system pretty
hard...

Barring that, does anyone have the boolean equations for U6 on the 1MB
upgrade? :)  The schematics are available, but not the PAL stuff ..
