Hi,
i made something really easy, a Covox Speech Thing on ISA Bus Card.
Using AD7524 Digital to Analog Converters and a simple Output Buffer with LM358.
It sounds really nice.
To get it recognized one simply has to modify BIOS Table and enter the Port Adress of each Channel.
This is done with debug.
A2 to A9 is connected to 8Bit Comperators, so you can set your IO Adress freely.
I tested already a Lot of Software but had no time yet to to make Recordings!
It does not need a IRQ like a real LPT Port.
Note i know it makes not that much sense as you also can play your MOD Files with a Stereo Soundblaster.
But its fun to try things out.
Stereo Playback works fine with Visual Player and some others, and it sounds nice.
Maybe i have time to do the recordings tomorrow!
I also will Open Source this Project.
So everyone can build one.
