Interesting! GODIL modules (AFAIR) were (are?) CPLD based? 

http://www.oho-elektronik.de/index.php?c=1&s=product1

These ones? There's one Spartan FPGA based but all are with small pincount. The larger ones apparently are no longer there.

Do you have more info/reference on that particular implementation?

Oh, and I trust there must be a comprehensive compatibility testing "suite" for that somewhere? I vaguely recall something running on a 1541... was it from VICE team?
