Of course, there is another way of looking at this.
The file on Zimmer's website was produced by William L. who most likely took the lid off his SuperPET and noted down what (EP)ROMS were actually fitted to his machine. If they were 2764's - then that's what was probably fitted to his machine when he looked at the time. Someone else may well have equipped the SuperPET with 2764 EPROMS on adapter boards (i.e. what William was actually looking at and documenting was his specific SuperPET at that point in time and not a general statement regarding what was originally fitted by Commodore).
This is why it is always wise to obtain two (or even possibly three) sources of independent data to either corroborate the position or highlight potential inconsistencies before undertaking work or modifications etc.
