[Coco] Wiring inputs to the Coco : Followup

[Bruce W. Calkins]

I got the book (Build Your Own Universal Computer Interface by Bruce Chubb) 
today and was disappointed.  It is a Second Edition and was rewritten for 
Pentium era computers with no mention that I see so far for 8 bit machines.
So, one needs to get the original Edition, and probably update the designs 
themselves.
