13) The slide switch SW 1 on the voice board is set 33MHz as a default. Change the switch to 66MHz.
The purpose of the slide switch SW 1 on the voice board is to change the frequency (33MHz/66MHz) according to the PCI bus transfer rate.
When the settings of the transfer rate and the switch are inappropriate, the voice is not played properly, resulting in catch during the play of the voice etc.
If the switch was flicked by an error, return it to an appropriate position.
In this machine, the switch must be positioned at 66MHz.
14) Insert the voice board [1] into the main controller PCB connector (J1012)[2].
Insert the voice board perpendicularly against the connector.
