title: POKE in ZX Spectrum
body: <p>I'm playing with an old ZX Spectrum 48k and I'm wondering how exactly it is possible to enter <a href="https://en.wikipedia.org/wiki/PEEK_and_POKE#POKEs_as_cheats" rel="nofollow noreferrer">POKE codes</a>.</p>
  <p>You load a game with a tape - then somehow break out of the program, type in the POKE statements, and start running the program again?</p>
  <p>I've done a lot of searching on this but haven't been able to find exactly how this is done so any leads on this would be greatly appreciated.</p>
