OK, using a 1 million gate FPGA to replace a 7400 is
overkill, but it would work
--
Not if the FPGA isn't 5v tolerant.
I am quie sure the problem of level-shifting between TTL levels and
whatever's common in 50 years time will be solved by then :-). 50-year-on
parts will be so much faster than good old TTL that the extra delay
caused by the level shifters won't be a problem either.
