There is some at ftp.funet.fi:/pub/cbm/pet.

The character generator ROM had them swapped, yes. Many machines upgraded
from Basic 1.0 to 2.0 at the same time as they got a new char rom,
but definitely not all. There were lots of machines with 2.0 Basic but
old char roms.
The reason why the chars were swapped originally does make sense.
If you switch to lower case more, text already on screen remains as
it is. I guess that having to keep shift depressed to get lower case
characters was considered too inconvenient. The result was new
programs looking funny on old machines, and vice versa. I have a few
programs that were obviously meant for the old char roms.
