A friend of mine had a Trek touring bike of that vintage, possibly a 728 (until it was stolen) and he commented that it took a 3/16 allen wrench to adjust the seatpost, not metric.
No I'm fairly certain to positive that this is metric. The older late 70s era Treks had 3/16s binder bolts; I know my 1978 Trek TX 900 does.
