  1. 2020.11.13 A2 OverDrive (APPLE II Accelerator) now playing 22Khz Stereo Music
  2. 2020.11.08 Stereo WAV Playing

Dear Friends and Customers,

 

 

I glad to announce these new features,

A2 OverDrive card can play 22Khz Stereo WAV files.

It has a 7bits INPUT with an AUX socket.

 

Now, sound much clearer and became HIFI sound as the attached video.

I'm very happy with it cause I can listen to nice quality music on APPLE II.

Even making the good sound, still have CPU resources and DISK bandwidth for more.

I hope to make a Music video player but, didn't understand how to convert video and sound for APPLE II system.

 

Anyway, Have a time to watch this Introduction with Music.

Stereo WAV Playing

◆ Accelerator / 2020. 11. 8. 16:29

Dear Friends and Customers,

 

Accelerator card name change to 'A2 OverDrive'

And built a revised PCB,  Add an AUX port with one more 8bits Digital output.

 

It can play Stereo 16Khz 8bits Way music as under.

 

I also tested to a minimized sound buffer.

Tested 12KB->8KB->4KB all size of buffer working without problem.

 

16Khz Sampling music is good to my ear.
