We know of AIX/370, AIX/RT, and AIX/PS2.
PS/2s were used as terminals or workstations connected to AS/400

Was there ANY connection of a PS/2 to a S/360 system? Maybe not
directly, perhaps by using something like a 3172 or an interconnect
gizmo?
That's what the seemingly ubiquitous 3270 cards are.-a They let the PS/2 connect to a 3174, 3274, or integrated workstation controller and
function as a terminal emulator.
There is also the bus/tag card which can be used to either "emulate"
channel I/O (so you can hook up a mainframe tape/disk/controller to a
P/390) or hook up as fast CTCA data path to a mainframe.
You could also hook up a PS/2 to a 360/370 system using an SDLC adapter
as a SNA terminal (or printer) device, but almost no one did, the 3270
adapter was more flexible and faster. Or you could make an async modem connection to a 3174, though again the 3270 was "better" unless you
needed to access a system miles away from your location. I did this
when I was required to provide off-hours support for a VM/HPO system
where I was the System Programmer.
And let's not forget about Token-Ring adapters for PS/2 to 360/370
system connectivity. Once they were in common usage, almost everyone
dropped the 3270 adapters, since you could do both terminal emulation
and TCP/IP with the Token-Ring adapters -- same with an Ethernet
adapter, but most IBM shops were Token-Ring for YEARS before switching
to Ethernet.
