I have installed several 720K drives, and none of them had a
terminating resistor.  Your drive may not need one either (or there
may be a jumper for it).

This is incorrect.  The drive should be set as drive *1* if the choice
is from 0 to 3, and drive *2* if it is from 1 to 4.  If you set BOTH
drives as Mr. Widell suggests above, the system will still work, but
the drive before the twist in the cable will be drive A:, and the
drive after the twist will be drive B:.
