Apple IIc expansion options

["**** ****" <***@***.com>]

Guys,
    What are the expansion options available on the 2c? I'm somewhat
familiar with what can be done externally, and I realize that there are no
internal slots. Are these slots totally absent from the design, or are the
sockets simply missing from the mainboard? It seems this would be the case,
but thought I would ask, rather than search around for the next 2 weeks.
I've read that there was a modem option, that plugged into it, what sort of
connector does this use, and do I understand correctly that this is an
internal connection?

Thanks in advance,
John Oyler
