     Yes. The card is a sound input digitizer (AD converter) which was included
in HyperStudio packages. You can plug in a microphone or other sound source and
record to memory using various sound input utilities. There is a socket to pass
through the J25 signals to a Stereo Card and a power cable which goes to the
12VDC pins located at the back of the motherboard.

     The standard Apple IIgs Memory Expansion Card holds up to 1MB. There is
some info about various other configurations at
