Replacing the 1541 mech with a microcontroller is relatively simple
(yes, I have also been thinking about this several times :). You only
have to monitor the motor control, head stepping, and r/w control, and
then output a continuous stream of GCR bytes. D64 sectors can be
converted to GCR on the fly. The biggest hurdle is giving the device a
decent user interface, and some way of uploading D64 images (USB + PC
client, SD card + buttons, etc).
Of course, with the absolutely fantastic 1541 Ultimate being
available, this is largely an academic excercise :)
