It worked with the Vivitar 5600, since it was one of the few flashes
that allowed setting the film speed on the flash (independently
from what was set on the camera...). The adapter is still around, but
it can't transmit the film speed for TTL use (if you look, one pin is
missing, compared with the ISO-Nikon TTL shoe...). I would like it
to work, but it doesn't if it doesn't pick off the film speed info
from the ASA ring on the F3 in some way...
