Yup, they use an early FPGA, whose configuration information is 
downloaded from a DOS driver.  I'm sure the driver code is around 
somewhere in form of Chi Corp's DOS Ninetrack software.  But without it, 
the cards are strictly decorative.

Probably perfect for a slower drive, such as the Qualstar 105x series, 
but unsuitable for the fast (75-150 ips) streamers.  Other than the FPGA 
configuration memory, the only memory on-board is a 256 byte FIFO.

The obvious limitation is that these really are 8-bit ISA boards.  I 
might have the software somewhere, but no promises.
