16*L*8?

Security fuses don't make much sense there ... If everything fails, just 
wire it to an EPROM socket and read the output bit pattern ("data") for 
each input bit pattern ("address").

Then just create an EPROM of same content and wire it to the PAL socket.

And if you really want the equations, feed the dump into a 
Quine-McCluskey minimizer or just do a batch-driven source generation 
(be it PALAM, ABEL, or VHDL), feed that into your favorite tool for 
minimization, and let it dump the minimized equations.
