Re: PET 50Hz editor ROMS

The data I posted previously had errors in it (none of you caught that, 
you're slipping). The corrected data is below (8296D register 0 and 
values calculated from it).

I have added the ROMs that use each set of data. 901474-04_ is still 
obviously PAL. 901474-04-3681 is the most commonly used set of values. 
That must be the standard.  There is still no explanation for 901474-04.
Comparing the ROMs, only the register values and checksum are different,
so there is no way to track modification history.
