Mystery card
I bought an Apple //e today with a card in it that I can't identify. The
connector
on the outside has a D shaped end with 37 pins. On the keyboard edge
of the card itself are 50 pins. On the solder side is something that
looks like a
lower case a with a line in the middle of the right side of the letter
(almost like a lowercase a printed on top of a lowercase c), then lower
case i then II followed by "-Dl (or I or maybe 1) - (o or 0) -
3285-00-03-04. In faded white is stamped on it "Jan 16 `86"
On the component side is "S/N 25-136" "rev G 02"
Except for a ROM chip which has the number 103684A printed on the paper
covering the chip, all the other chips seem to be various logic chips.
I doubt it
will help to identify this card, but I'll include them just in case:
