Someone must have opened up their cartridges with Jupiter Lander, Radar
Rat Race and the other early stuff. The date codes on the ROMs should
be some kind of indicator.

I get some impression that they didn't even believe in the Max that
much when it was new as atleast Radar Rat Race is a direct port from
VIC-20 and as it shows a small image with the same amout of data as the
picture on a VIC-20 it's actually worse than the VIC-20 version.

In Sweden there were more or less no stuff about C64 in the magazines
until sometime mid 1983.
