That looks pretty neat - I may have to get one or two of those for my Apple ][s.

According to http://fd.fabiensanglard.net/prince_of_persia/Inside%20the%20Apple%20IIe.pdf (around page 365), this card has signature bytes that indicate that it is compatible with the Pascal system (signature bytes at $38 and $18 $Cx05 and $Cx07); further, the code $15 at $Cx0C shows that this is a printer interface card.
