Alright, it seems you still hacked it. -Thanks for feeding my curiousity.
Didn't the new C-64 look somewhat like the

imagine they were less friendly for repairing in a hobbyist/repairman

There were two aspects to this. One was the case, including the keyboard
with the different colored keycaps, and that wasn't all that big of a deal
once you got into it. The other was the fact that they kept on changing the
board inside, there being a total of four or five different revisions that
we saw a lot of . Earlier units had differences in the video area, the
on-board 7805 regulator standing up rather than laying down, and similar but
the first three or four revisions were pretty similar. Then they did stuff
like combining the eight RAM chips into two, combining two of the three ROMs
(Kernel anb BASIC if I'm remembering right), and combining the PLA with some
other random logic to cut the parts count, those were a bit more of a PITA
to work on.
