The Turbo shuold be the same as the standad 6502 C0-processor wihich has
a pretty simple layout:

FFFF
       Tube hardware
       OS (RAM Copy)
F800

       Free RAM

C000
       RAM copy of Language

8000

       Main User Mem

800
       Language Workspace
400
       OS workspace
000

If you use a Hi language it starts at B800.


Langauge workspace is used exactly as it would be on the host.
Page 0, 0-EE is not used by the OS (though it probably is by the language).
Page 1 - stack
2      Vectors
3      error messages

P.S. I've got a music 5000, and would like to hear any good demo's that are
around.
