UNIX/370 was the name adopted by two separate efforts to run UNIX on an IBM System/370 class machine.
The first, at Bell Laboratories, ran Unix Seventh Edition as a 'supervisor' to user processes, under the TSS/370 Resident Supervisor. This approach, instead of running it directly on the bare hardware, was taken because System/370 machines had characteristics which made doing so un-attractive. For one, the I/O system of the System/370 was quite complex, with a large number of channels, device controllers, and devices, which could be interconnected in multiple ways. For another, IBM field service expected the operating system to provide error logs in a particular format, which UNIX running on the bare hardware would have to provide. The TSS-based approach was successful, and Bell ran the result on a number of large System/370 machines.
The second, originally at Princeton University, proposed to run UNIX Sixth Edition under VM/370; this was made to run in a preliminary manner. The project then moved (along with its progenitor) to Amdahl, where it ran on an Amdahl 470V/6, under VM/370; the result was named 'Au'. (Amdahl later got UNIX Version 7, and then announced Amdahl UTS.)
