You can patch FaccII to use a device different from trackdisk.device,
you have to change the name of the FaccII.port too if you want to
use FaccII for disks AND for a hardrive.
Nevertheless, unless you want to read a short file that can be hold
in the cache several times, you'll get a severe slowdown. The FaccII
program might be faster than floppies but it is definitely slower
than a harddrive. And it doesn't help against disk thrashing (write-through
cache).
