Just from curiosity
I saw two variants of A500: One with C= Logo near the "status lights"
and one with Commodore A500 near the "status lights"
When i whas replacing the FD Drive (by Chinon!), I found on board text like this:
B52 / ROCK LOBSTER
CPR/JSP/CUAY/FISH
RVW/VFA/DCA
GET/LLK/ITCH/BCN
C= A500 REV 6A
And found strange thing: The power light is green instead of red and vice versa
