Although I didn't have time to open up my two-prong with a serial number in 
the range of 6000, I can't recall ever seeing the early NTSC type 
motherboard on a PAL VIC before.

I have read in then contemporary magazines that the PAL 6561 chip was quite 
delayed, which means it took a while between the US launch and the European 
one, and that availability at first was much less than demand. Could it be 
so that Commodore at first adopted the NTSC motherboard (clock etc) to PAL, 
and while waiting for chips they redesigned the board so the number of units 
with the older board were very few as the new board got ready in time for 
when they could start shipping computers?

Best regards
