I have this mystery card. It came to me with no documentation, no verbal history, no indication of where it came from or where it's been in life.
It appears to be "asp" serial and parallel card, yet there is no crystal. The DIP switches are labeled to control baud rate only. I do have headers for it, but with a header present, the combination will NOT fit in an Apple II/II+/IIe case--the card is too high physically to allow the sunroof back on. I assume it's for some other variety of the fruit?
I have found nothing on the Internet about this card.
I tried it in an Apple II+ but could not get anything happening on the apparent serial port.
Does anyone recognize this card or can tell me what I have? Thanks in advance,...
