It happened to me as well.  Normally, I use a small program I got from
somewhere called "BOOT5" from the Orca Shell (I boot into it, and use
aliases to get everywhere).  It didn't work with ACS.  However, if
I typed PR#6 from Applesoft, the ACS logo shot up fine.  However,  a cold
boot from slot 5 munged the screen.

I tried changing the system to 50Hz to see if one of the demos would work
better (I didn't think it would, but who knows?)  FYI, the monitor didn't
take the top of my head off with angry electron beams.  Switching to 50Hz
also changes all the control panel settings back to the defaults.  Boom!
Upon switching back to 60Hz, the ACS demo boots fine, even with that
Boot5 program from the Orca Shell!  No more munged stuff.  Unfortunately,
I have no idea which setting it was.  Perhaps something was lurking in
the battery RAM that was planted there by a rival french hacker group.
I tend to think it might be the Display settings I had.  I normally have
the machine boot up in 80 columns.  It's now back to 40.  Now that I
think about it, the munged screen looked like some kind of bank disaster
had messed it up.  I'll have to try it when I get home!
