Mockingboard for IIc

이안김 2016. 1. 23. 22:35

The APPLE //c has no expandable slot and it has no support by sound card such as Mockingboard.

So, If you play some game on //c, It would be some disadvantage compare to APPLE //e with mockingboard.


Due to this lack of this capability, I tried to build mockingboard compatible sound card and completed designed.

Now, It works very well as the Mockingboard A/C(no voice chip).


It was required accurate timing control and firmware conflict evasion techniques.

APPLE //c doesn't have I/O slot and I needed to make required signals.

For this, I used CPU socket for it.



This sound card can be used on APPLE Iic 4000and 4100 all models.(Not //c plus nor Laser128)

Tested more than several days and no any issued encountered.


I prepared a AUX sound connector for external speaker.

And two small speaker provided for pre-order users.


Anyway, I'm receiving pre-orders from the Korean APPLE II enthusiast,

About a month later, I will put some on eBay for international APPLE II enthusiast,

If you have this device on your APPLE //c,  Your APPLE//c would be almost complete sets.


If you have any concerns or question, please let me know.
Before to finalize it, I will try to apply your idea for perfect one.

Thanks;
Ian Kim

** ADDED **
Present sound card has semi-fixed sound volume so, I'm enhancing it to be able to control as followed APPLE//c Volume dial (It is located on left side of APPLE //c).
It would be controlled sound volume by APPLE //c itself without other device or connector.
