[Coco] C64 converted into low operating keys

[Brian Blake]

Bill,

He was also working on another version which he told me was more along 
the lines of an add-in sound card with far more features than an O-90. 
We did discuss the cart you described, but, he said he had other ideas 
as well that he had no uploaded to coco3.com or the Maltedmedia FTP. 
This conversation took place probably a month or two before he vanished 
from the list. I'm trying to find those email messages right now - so 
far, no luck...

Brian
