   From the comp.sys.apple2 Frequently Asked Questions (FAQ) at
http://www.visi.com/~nathan/a2/faq/csa2.html section 2.4:

--- snip

The //c had a number of internal revisions; the best way to check is
to go into Basic and type "PRINT PEEK (64447)" and press return (no
quotes). If it says 255, you have a very old //c; most of those
motherboards had problems that prevented most //cs from getting
reliable serial communications on faster than somewhere in the
300-2400 baud ranges. See your dealer about getting an upgrade, which
is apparently no longer free (tell them that the Apple authorization
number is ODL660, and try anyhow). If it says 0, you can connect a
3.5" drive, but you don't have the internal memory expansion
connector. If it says 3, you have the internal memory expansion
connector-- extra RAM can be added with certain cards.  If it says 4,
you have the latest model of the //c. If it says 5, you have a IIc+.
