[Coco] FD-50X series power supplies

The FD-501 & 502 were a little under rated in that Radio Shack installed a 
fan with the dual disk drive installations.  It appears to be more of a 
cooling issue than a part rating issue though.  I have used CPU fans from 
dead PCs instead of Radio Shack's can motor kludge.

In short, I have not seen a disk drive power supply fail from normal use.  I 
have even bypassed the transformer and plugged in to the truck's "12 volts" 
without any problems.
