you can use _textshadow and ram page 1 for scratch space. 

you typically would load data into it using either:
-1 byte loads: ld (_textshadow),$ff
-ldir copies:  ld hl,source \ ld de,_textshadow \ ld bc,400 \ ldir
-10 byte loads: ld hl,source \ ld de,_textshadow \ call _mov10b

ram page 1 starts at $800b and ends at $bfff-22 or something.  just start
around $800b and you'll do fine.
