But I thinking more on a solution to directly connect to the 8bit port data
of the DiskOnChip device to the PIC. On the DiskOnChip you have data port
and address port, plus a few control pins, so it is like a slow NV SRAM,
much cheaper, thus having to use an intermediate USB connection is
unnatractive. The problem I face is that you cannot access it like a SRAM
because the driver expects you to work with it like a FAT16 disk.
