[M100] TSDOS + page fix

[Joshua O'Keefe]

Does anyone have a M100 TSDOS rom image with Ken's page down fix?  Or 
instructions on what to patch?  The one Kurt used for SARDOS has it, but I'd 
like to have a TSDOS-only rom on hand if possible.  I'll come around to 
learning SARDOS eventually but I'm not there yet.
