On second thought, I concur. The fingers seem to
match the Apple II
slot (power and data lines in the correct positions), so it is very
likely an Apple II card.
Naaah, I disagree.
Sure, it yelled "Apple" at me immediately.
But it looks like the power is in the middle, by C1... and Apple II power is
at the (what would be in this pic) right hand side, and those look like
signals going to the 244.
