I tried the following code on my 83+, and it just does nothing and the tios resumes:

org $9d95
  pop hl

  ld a,r  ; very pseudo random byte
  ld e,a
  ld a,r  ;byte not really random anymore, just 2 or three bytes higher than
  add a,a ;the previous, so double it, to increase randomablility
  ld d,a
  push de
  push hl
  ret

therefore, I would assume The TIOS has some error correction for that
weird...
