Serial adaptor "8 din" to "9 pin"

[RFBG67A@prodigy.com (Stanley Schroeder)]

     I have a Hayes modem that has a built in cable on it with a male "8 
din" type connector, and I want to use the modem on an Apple ][e that has 
a "9 pin" type of serial connector. (The modem was one of those little 
cheapies that came with "Prodigy" software for the Mac Plus.)
     I have the parts to make an adaptor which goes from a male "9 pin" 
to a female "8 din" so I can connect my modem to the "9 pin" serial on my 
][e, but I need to fine out how the wires go !!!  Does anybody know where 
I can get a wireing diagram to make such an adaptor ?
     And I was also wondering if the "9 pin" serial ports of the Apple 
][e are the same as those that are on the Mac 512ke so I could 
interchange such an adaptor.

     P.S. I read the posting about connecting a ][e to an AppleTalk 
network; how can you tell the difference between a regular ][e and an 
Enhanced ][e ?  Is it stated on the label or motherboard ?

Thanks in advance !
