Is there a catalog, or some outher SYS1. dataset residing on the volume?

Yes, unless you had authorization to examine the running Master from IPCS.
There is an address space named MASTER; I don't know how many jobstep tasks run
in it these day, but I suspect that it's still only one.

Thanks for the brief on what the TIOT is (which I could have looked up).
However, I don't understand what you mean by 'run the TIOT in the master
address space'.
Do you mean to dump some address space, and then look for a specific data area
with IPCS or some such?
