Thanks to everyone that provided help for the drive controller problems
I was experiencing.  I put a jumper in the controller to allow me to
use the leads on the drive controller standard interface, 3 and 4, to
let me power the pack over these leads.  I hacked a power supply in
the drives themselves, and used this to run the 12V devices on the pack.
I think it's probably what one person that helped out did.  And as he
said, it's not standard, but it works.  It also is invisible.  Also,
as I was told, the COCOMAX I uses a part of the address spectrum for
hi-res control that the COCO III has allocated for something else.
It starts to load the first time, then stops.  Second time, it prints
the DISK BASIC information.  Anyway, from what I've heard, COCOMAX III
ought to be pretty impressive.  

Again, thanks to everyone that helped out, and also for the extra
interesting tidbits.  My daughter should enjoy her new machine.
Now I'm about to try to teach a six-year-old BASIC... (I figure by
the time she's about twelve, she can build me a nice 100 MFLOP
graphics processor...
