That looks like an IBM 3174 01L. I still have 4 of them running. The tape drives are IBM 3420 Mod 6 (we still have 3 of them running). I don't see the IBM 3803 to run the tape drives. The rack mounted unit, reminds me of the IBM 9370 (not running one of them). Of course, the terminal is an IBM 3278 Model 2.
