Sorry Gene, they left out the 12 volt supply on the CoCo 2.



Yes a later disk controller might be a little more reliable.  26-3029, 
FD-500, FD-501 & FD-502 are all 5 volt units and work as is with the CoCo 2 
& 3.



There is a major hack for the 26-3022 controller to use quad-density drives. 
Although 15 years ago I could not find the parts, let alone a 26-3022 
controller.
