book on PAL/GAL programming?

I liked "VHDL for Programmable Logic" by Skahill.

Note that it covers VHDL and Cypress PLDs, rather than PALASM and
Lattice GALs.  The concepts it teaches are all relevant; you'll just
have to deal with the significantly different syntax of PALASM and
the lesser capabilities of the GAL parts.  (Or use Xilinx XC96xx
parts instead.)

For more in-depth coverage of VHDL, I quite like the "Designer's Guide to
VHDL" by Ashenden.

I'm not sure what's out there in the way of books that directly cover
PALASM.  There are probably some good books on Verilog.

On the U.S. west coast, almost all ASIC design is done in Verilog.  I'm
told that VHDL is used for most ASIC design on the east coast and in
Europe.  However, VHDL seems more popular for FPGA and CPLD design
everywhere.
