I have had a similar problem myself. However, I download the files onto an 
Apple //e first, and then transport them to the Macintosh w/ Passport. However,
the filetype comes out wrong. To correct this, I tried to use ResEdit to change
them to APPL or SIT!(I used Macdown on the //e to view the filetype.) When I 
changed them to APPL and executed them, it gave me a system error 26. (What
does that mean?). Now the only thing I can think of doing is to connect the
two with a null modem cable and transfer the files using Red Ryder with
MacBinary to keep the correct filetype and creator.

This is where my problem comes in. How do I make the null-modem cable? What
do I have to connect? I know that the RCD and TXD pins have to be cross-
connected, and the GND needs to be connected, but what else? I would appreciate
it very much if someone could give me a connection diagram for a null modem 
cable.
