Not a lot. The Color basic Rom Code 1.2 from $A000 to $BFFF has 
about 10 bytes or so. The Extended Color Basic Rom is full and 
Super Extended basic Rom has 1012 bytes free from $FA0C to 
FDFF.  Finally DOS 1.1 ROM has 167 bytes free. 

Not really much room to do a screen type editor. 

Now if you map the 8K space from $C000 to $DFFF as internal rom 
and get rid of the author's picture you can recover about  7376 
bytes. Otherwise you have about 1172 bytes give take a few. Could 
be more depending on how much of the old DLOAD code is 
patched and what isleft of it can be overwritten with a patch.
