There's a ProDOS 8 Technote defining a convention that allows programs to
tell the difference between a slot3 RAMdisk that uses Aux Memory and one
that doesn't.

I don't know how well this works in practice--there may be 3rd-party RAMdisk
drivers that don't follow the convention.

Anyway, this question is separate from the one of using non-disk cards in
slot 3.  There's no interference between a "slot 3" RAMdisk and the physical
slot 3.

Yup, it will work if your comm program lets you configure it to use a serial
card in slot 3.
