Among the large number of OPL3 cards i re-found was this one which I haven't seen much of on the web. (I actually found this one in another box that's been in storage, not as good of a story as the opl3 cards) I'm probably going to put it on ebay but I wanted to share it first as it's the only one I've ever seen. (i believe it's a re-branded IBM) (edit: I forgot I had posted pics of it on here but without the disks or box)
