Speech phrases stop partway (for example Gorgar says the first words of a phrase but not the last one).

A word missing from a speech phrase

Cause: One of the five sound lines stuck, bad speech data in an EPROM, a speech board fault, wrong DIP settings or mis-seated ROMs.

Checks

• Power off, unplug 10J3, power on and press the sound board test button.
• Sound only with no gaps: the board is sensing a speech board problem.
• Gaps, garbles or static between sounds: suspect speech ROM data or a speech board part.
• Check the two DIP switches, that each speech ROM is in its right socket and that the ribbon cable is seated.

Fix

• Fix the line, ROM or board found.
