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.
On an Apple the pins 45 and 47 (the way this card is numbered) would be
daisy chained to the other side.
Not Apple IMO.
