If you put the program in 4 times, it should work in a 4kx8 EPROM, you
know, the 2732 series of EPROM's used in the C3 ECMs.  This is four
times as big, but it will probably still work.  I don't know what your
application does with the N/A pins that are used on the '32, so load it
four times.  One of the four ought to show up in the right place.
