The best approach would be to have a small amount of code inserted into 
the Edit command to turn off interrupts and switch to internal ROM mode. 
Then you new code can do its work and jump back to the Edit patch. The 
Edit patch would then return to RAM mode and restart the interrupts. You 
can use the Super Extended Basic graphic routines as a model for this 
approach.

Ultimately, your new ROM code should patch Edit on startup to add new 
vectors. That may be what you are now doing.
