Apple II mistery card...
Dear all,
I have a card that is not marked, in the Apple IIe I recently bought, and
was hoping that a knowledgeable kind-hearted member of this group could help
me find out what it does.
It contains the following ICs: 74LS00, 74LS05, 74LS32, 74LS107, 2 X 74LS74,
74LS86, 74LS283, 5 X 74LS367, 74LS138, 74LS20, 74LS373 and an unmarked
40-DIP IC. It has no connector, no block-header, nothing. Only a little red
LED with the text next to it that reads: "CARD ON". There is also a
4-position DIP switch.
Does anyone have any idea?
cheers and thanks in advance
