Thanks Tom... thats the bit I needed (I had been searching for slightly
the wrong thing) !

Unfortunately it didn't quite get me all the way there.
I'm using my own sfp.insight file (modified from the original .gdbinit68
file used with 
the coff gdb).

I succeed with connecting to the target.

I can do chip select setup ("addresses", "setup-cs") from
"setup-and-load" (I tested it manually
from a console window of gdb).

I can examine memory using "x /100 100" in the console window, but
occasionally it comes
back with "BDM error: Invalid target command". It really does seem to be
talking to the target

I can't load files though !!
If I try "load afile" in the console window it always comes back with
"Error: Not an object file".
I get this error for binary, elf and coff format files. I have tried
both explicit paths or
"cd xxx". "Download" menu option fails with the same error. It's a bit
of a mystery whats going
on here !  In the old m68k-coff-gdb "load" used to load a binary image
no problem.
