Re: ECHO+ Card

["Eric" <lonewolf@hotmail.com>]

Echo II+ has the capability to produce stereo sound effect (the 2 x
AY-3-8913 chips) and speech (TSP5220 chip) I think.

However, I have not seen any games or software take advantage of the sound
effect.

Don't think you can play Apple II sound thru the Echo card, but you can play
echo sound through the internal speaker using the 2-pin connector (labelled
as "Apple Spkr" on the card) connect to the motherboard.
