I was blown away by the inclusion of the IBM PCjr's speech attachment in the built-in diagnostics. This machine's engineering continues to surprise me.

If the speech isn't clear, the words are "up, down, left, right, warning, well done, gotcha, zero, one, two".

For those thinking this is a speech synthesizer, it actually isn't; the words are prerecorded and there are less than 200 of them. However, there is a microphone jack where you can record voice at a fairly high compression rate via CVSD.
