Oops, the pictures I provided were not the latest. There are additional modifications beyond the 8 data lines. Because the data port is now 16-bit wide, the address lines need to start from A1 to A3 instead of A0-A2 of the original design. This changes the memory map associated with CF interface. I also need to make change in CPLD to tell 68030 that CF is 16-bit wide port. So you'll need to reprogram the CPLD and reprogram the EPROM.

Give me a day or so to come up with an engineering change detailing all the changes needed to convert 8-bit CF interface to 16-bit.
