PLA programmed equal at same Commodore's part number!
More originals than originals:
For own computers Commodore initially has programmed PLAs (supplied from market by vary brands),
after this the PLAs was produced, saving too much, directly by Commodore with terrible consequences:
on C64 "breadbin", for example, the PLA became the first reason of fault....
My chips are PLA (NOT produced by Commodore) that I have programmed with same logical equations of relative Commodore "part number", each PLA is tested with "vectors generator" that supply the PLA under test with all possible input configuration (65536) and for each of them will checked the correct response.
