Hmmm, yep, you're right, no TTL with it or any other flash unit, Olympus or
otherwise. Only two contacts on the OM-10, the flash trigger center
contact and the "flash ready/flash OK" contact. The third contact missing
from the OM-10 (along with the circuitry to support it) required for TTL is
the "flash quench."
Dedicated flashes such as the T-20 and T-32 must be used in "Manual" or
"Normal Auto" modes, and cannot be used in "TTL Auto" mode with the OM-10.
"Normal Auto" uses the sensor inside the flash to quench itself (just
behind the center of the "O" in "Olympus" on the front of the flash).
