Since Is is not well controlled and is temperature-sensitive, the results will not be very good, especially outside of simulation land. If either of the input voltages are negative, the op-amps will rail, and for a 741 operating from +/-15V supplies (and the Is used in the Circuitlab model) the maximum input voltages are only a few mV before the output saturates. The main error currents in the circuits have been reduced to very small.
