I think the FastTrak 100 has an internal EEPROM with either the PC or the Mac code on board. With the EEPROM internal, reprogramming it is problematical. I've never heard of anyone converting one of these cards.

The Acard 6280M is fairly cheap on Ebay these days -- less than $20 pretty often. The 6880M and 6290M turn up as well (ATA RAID, SATA non-RAID).
