I am replacing the old attic fan motor with a slightly less used one
from another house. The motor is a a two speed motor, but this house
is only a one speed wiring and switch.
After installing it, using only the high speed terminal, the fan is
going in the wrong direction. I tried reversing the wires in the box
to see if that'd reverse the direction but no joy.
Does this indicate that this motor cannot reverse direction?

Could be. Is the wiring inside a box with a plate on it? Some have wiring
diagrams inside, some have a plate on the motor. Some have none and cannot
be reversed. Check the manufacturer web site also.
