Probably the -03 then. It existed as a Mask ROM in early systems. Most 
systems did have the -04 and -05 though. Commodore even replaced the 
kernal in some systems with a -05 afterwards (the kernal ROM had a '86 
datecode while the rest of the chips were all '84). That makes me assume 
that some bugs were pretty bad.

Here's the 'cmp -l' output between -03 and -05:
