but I too am getting graphic problems with the foreground graphics
(cars, signs, etc...)
And I also did some Googling and found an Atari Tech note which said
that problems with the foreground objects
can be caused by problems with Horizontal Address counter chips (74LS161)
located at 9H, 9K, 10H, 10J, 10K and 10L .
So can anyone confirm that I'm looking at the right area,
or am I way out in left field ... ?
Here are some pics...
Let me know.
Thanks,
Steph
