Hey Everyone -
I hope that you all had a good holiday.
In follow-up to the problem that I'm having in achieving consistent stereo sound output from my IIgs ROM 3's CPU (which I explain in detail in my 11/13/2011 entry within the AppleFritter.com Apple II Forum), I found the following Apple IIgs sound card currently listed on eBay for sale.
I'm unfamiliar with this eBay card's brand, and I'm not sure based on its accompanying eBay description (or any other information about it that I was able to find on the Internet), that this sound card would be any more effective than the partially-working Apple //e Enhanced-designed 1986 Mockingboard stereo sound and speech output card that I currently have inserted in Slot 4 my IIgs ROM 3's motherboard (which works and produces stereo (different sound to the external Mockingboard card port-attached left and right external speakers) sound only for my //e Enhanced-specific Music Construction Set software.
But then, the IIgs ROM 3's CPU automatically switches its sound output from this inserted Mockingboard solely to its non-split-sound (identical sound sent to both a left and a right externally-attached to this built-in 3.5 mm earphones/external speakers CPU port), when I use IIgs-designed Music Construction Set software (loaded from [virtual] Slot 5 via a 3.5" floppy, directly upon powering on the IIgs), and also when I use all other music creation software that I have that I've tested by running it (stored on a hard drive) after having first loaded (from that same hard drive) GS/OS 6.0.1.
The eBay Listing for this IIgs sound card that I found is: 320722692829.
I'd really appreciate any information that any of you AppleFritter Members might be able to offer! (Including, if you think that this particular sound card that I found on eBay will not solve this problem, any other currently-for-sale IIgs sound card Internet for sale listing[s] that you may know about on eBay or other Web site[s].)
Thanks very much!
Best Regards -
