[Coco] CoCo2 Strange Side Switches

[Louis Ciotti]

Can you verify where each wire really goes?  from prior posts we know one
goes to the second pin down from the upper right.  Maybe some better photos.

I wonder if this is a mod that is just wired wrong...  Is this a CoCo 2b
with real lower case?  Seems like this would be the green border and the
true lower can mods
