Easy.

module ti74ls00 (a,b,q);
input [3:0] a;
input [3:0] b;
output [3:0] q;
assign q=~(a&b);
endmodule;

I prefer to think that the ECU emulators of the future will be open-source.
Look at the emulators for classic arcade machines, Apple ][+, Commodore64,
Atari 400/800, Amiga, etc.  Modern computing hardware and the tools to
program them are so powerful that it's possible to reproduce what 
was 15 years ago on the cutting edge of technology by a college kid in
his spare time.  A 1985 Amiga is way more complex than a vintage 1985 ECU,
so it's only a matter of motivation.
