Wanted : Used Serial card for Apple II+

[rmb2491@tm0006.lerc.nasa.gov (ROB BUTTON)]

Do you have an extra Apple II+ serial card laying around somewhere?
I want it.  I would prefer a Super Serial Card because of the 
flexability of the port set-up.  I am planning to connect it to a 
specialized application with unknown handshaking.
I also need the manuals, since I will be writing my own interface
drivers.
Please respond to rmb2491@tm0006.lerc.nasa.gov if you have such a beast.

Thanks,
Rob Button
