I got this card with a system I purchased complete, and found myself not really using it. The SC-01-A chip itself seems to fetch a sum of $200-$300 (!). This card has no docs I can find, but here are pictures of front and back:https://imgur.com/a/JaDamZ5
I tried random softwares with it until I was able to get some voice out of the old HULK text advenure. The card doesn't work completely as expected for the game (although this may have been a beta disk imafge) but it seems to indicate the SC-01-A is fine, and you can hear it here:
As opposed to or before auctioning this off, I would like to just offer it for an even $300 to an AppleFritter member, with hopes it won't get taken to just scavenge the SC-01-A IC by a random buyer. Open to reasonable offers, and I will cover the cost of insured US shipping.
