There certainly isn't any still running 705 which serves useful purpose. In fact they were probably all replaced by 7080s and then 360s in sixties as 7080 is software compatible and specific 360 models have some support for running 7080 software. Also the software that ran on these machines is probably simple enough that it got rewritten for more modern machines cheaply.
