Everyone,

Here are the schematics from my first version Lowerkit remake if it helps.  
The info is all in the data sheets, though of course, gotta parse that stuff. :)

It worked just fine and was based on the earlier versions (all old school ICs).

I miss you guys and the whole CoCo community.  I'm hoping to to get more involved again soon.
