Yes, I hacked up one of my CNC control boards to make it 
into a read-only adapter for Pertec formatted drives.  Works 
well, but is pretty slow.  I've thought that using the PRU 
(attached 32-bit, 200 MHz micorcontroller) on the Beagle 
Bone would make a really great formatted Pertec interface.  
One problem is limited memory directly on the PRU, I haven't 
learned yet how to use the bulk system memory from the PRU.
