It could be also socketed but most likely the chip is secured so it can't be read with a normal programmer.If your programmer support the
PAL16L8 chip try to read it.If you obtain a .jed file filled with '1' 
then it means the device is secured.You need a special dumper in order to dump contents from secured PLDs (obvioulsy then dump must be analyzed in order to recreate equations for a GAL16V8 replacement)
