Hello. Pardon the basicness of this request, but I don't own a Mac nor do I
have access to any Mac reference books (otherwise I would most certainly
RTFM ;-)

I need the pinouts for the 8-pin Mini-DIN connector (at least, I *think*
the Mac II uses an 8-pin mini-DIN connector for its serial port - I'm
certain I'll be quickly corrected if I am mistaken). I've seen cables which
connect the Mac II serial port to a standard DB25 (for use with a Hayes modem).
How are these wired? 

(Warning, Will Robinson - Crude ASCII graphics to follow!)

I picture the connector this way:




    __________
   /          \
 /  6   7   8   \
|                |
| 3   4   X   5  |
 \              /
  \   1   2   /
    ---------

Note: The real connector has a round shell, not the abomination I have drawn
here. Also, the 'X' indicates the absence of a pin).

Given the above pin numbering system, how does a standard Mac II to DB25
cable connect, pin for pin?


Many thanks in advance for all assistance you can give. Please email me unless
the response would be of general interest.
