Looks like there's schematics, information about
trace errors on the
board, and some experimental equations for the PALs, but apparently
the originals are lost.
PALs are simple two-level programmable logic. It shouldn't be hard to
create a truth table from the real PALs by adapting them to a PROM
reader. From there you can recreate PAL equations from the truth
table.
