You have to set the correct rom-page here. You know, ti-85 has 128kb 
of rom, and only 32kb of it is visible to Z80 simultaneously. The 
CLEARLCD  routine is in the page 4. So we put  this here:

ld a,4
out (5),a

You have an error here. Replace it with:
Loop:
 call GET_KEY
 cp K_EXIT
 jr nz,Loop   ; = jump if key NOT pressed
