I don't know, didn't check that version.

But I see no point in invoking the 6502 to execute some ROM code in
the serial card, since all you have to do to access the serial card is
to read, or write, some ports (which are memory mapped on the Apple
II).  And that is more easily done in Z80 code than setting up a call
to some 6502 ROM code.
