Really Great Job, Everyone who has an electronic PDF copy of the CoCo3
Service Manual should keep your file next to it.
I wish that I could place your file where I found the one scanned 2
pixel / inch. But I almost got killed the last time I offered to do
anything like that. (And no one else has done anything as far as I can
see in what, two or three years and it has gotten more and more files
not sorted. *eg* )
I see you are on Facebook, do you want to make a post there or should I
do it? Don't forget the OS-9 group.
