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.
