Schematics/Info for differents boards layout..

[Mauro72]

Hi,

I'm searching schematics from differents boards. Example, in one board L27 is present, in other board not exist. Some inductors are with different value too.

Another example, the repair manual from coleco put check R40, C62 in B/W image (sheet 4), but that resistor/capacitor no appears in my coleco board. How can i trace that?

Is there some technical info/manuals with the differents revision?

Thanks!
