This is the same card as mine, right here. I'm not sure I buy the  
seller's description of it as a parallel printer card, though it's  
certainly possible. I could accept the description if somebody were  
to find some other corroborating evidence. 

Interestingly, it was also removed from a 5271.

Actually, the more I think about it, the more it makes sense that  
it's a parallel card. Would the 5271 have been capable of using the  
Async Adapter as a host interface? That's the only remaining I/O card  
in the machine.
