   The pinouts for the mini Din-8 connector (and tons of other Apple
II connectors) are available at
http://www.visi.com/~nathan/a2/faq/pinouts.html

   Hmmm. I'm missing a full pinout for the 9 pin serial and 25 pin
serial. Time to do some hunting.

   9 pin serial is something of a standard. Note the Apple did put 9
pin connectors for various devices (Joystick, early mice) on various
Apple IIs and early macs; those are NOT standard serial ports, though.

   This error message is contained in the comp.sys.apple2 Frequently
Asked Questions (FAQ) post, which was posted here on the first of the
month. Your local news server _should_ still have a copy, as the posting
was configured to expire in a month. If it is not available, please
contact your local news admin to help fix your feed. If you skipped
over unread articles such as the FAQ before posting (a very bad habit),
you can read it on the WWW at
http://www.visi.com/~nathan/a2/faq/csa2.html

   A more detailed list of differences between the regular and
enhanced //es is in the FAQ; for a quick check, the best way to check
is to turn on the computer and look at the top of the screen. If it
says "Apple ][", it's unenhanced. If it says "Apple //e", it's
enhanced.

   Please note that to get an Apple //e on Appletalk, you must also
add a 'Apple II Workstation card', which provides the interface to
talk to an Appletalk network; neither the regular or enhanced //e can
do this on their own.
