The Oracle Thinks

An answer that arrives instantly feels cheap. Add a thinking pause — a delay loop with a SID tone humming for its length — and the answer means more because you waited for it. That's suspense.

67% of Oracle

There's something wrong with an Oracle that answers the instant you finish typing. Wisdom takes a moment. So make the player wait — a beat of silence with a low tone humming, and then, only then, the reply.

A C64 screen showing only SPEAK, MORTAL? WILL IT WORK — the question asked, no answer yet, the Oracle thinking.
The moment of suspense: the question is in, a tone hums, and the screen holds its breath before the answer comes.

The new part is the subroutine at line 300, called by GOSUB 150 before the answer prints. It gates a SID tone on (POKE 54276,17), holds it through a delay loop (FOR T=1 TO 800:NEXT T — counting to 800 does nothing but take time), then gates it off. The screen sits on your question, the tone hums, and the answer waits.

That pause is suspense — and it's something you build, not something that happens. The answer hasn't changed; the wait has changed what it's worth. Too short and the Oracle feels fake; too long and it feels broken. Find the beat where the player leans in.

Try this

  • Tune the wait. Change 800 to 400 (hurried) or 1500 (ponderous) and feel the difference in tension.
  • A different hum. Change the pitch in line 300 (POKE 54273,20) — a lower note broods, a higher one frets.

What's next

The Oracle thinks now, but every answer looks the same. In Unit 5 colour gives each reply a mood — green for a yes, red for a no — read before the words even land.
