I have now finished comparing the 8296 PLAs.  I found out that
André Fachat's commented logic equations in "829desc.txt" in the archive
82s100.tar.gz contain some errors.  Only one equation for UE5 is in error,
and only two for UE6 are correct (unless I made some mistakes).  However,
the output from his tool is correct.

I uploaded C programs that contain the correct logic equations for each
PLA.  When they are run, they generate a 64-kilobyte truth table dump
that can be compared with a truth table dump of a real PLA.  (You may
need to permute the inputs and outputs in the program; the programs now
correspond to the mapping generated by Jens Schönfeld in 1994.)
