The fist Mockingboard Sound card that can be installed internally in an Apple IIc has been produced by Ian Kim (Apple II Forever).
There aren’t many details about the board, but it seems it won’t be available for the general audience anytime soon.
According to A2Central, the first batch of cards are going to Ian’s friends with international sales coming later (No, you cannot friend him on Facebook just to get it). Although you can install it internally on the IIc, you cannot use the expansion card at the same time. There is no further information about prices either.
I know, this post is more about lack-of-news than news, but at least know you know you will be able to make your IIc to sing soon!
