I got a freebie ISA card with adapters for what I thought were floppy drives, but it appears an IDE cable fit on it. There are 3 adapter sockets, one appearing for Floppy labeled SONY. The others; Mitsumi and Panasonic. It has silk-screen for SMC (chip IDs as SunMoonStar)- 31083 Ver 1.0
Two white connectors for power and audio I presume and two more jumper sections. There is an CN6 marked audio jack on the backplate, here again, I'm just guessing
Any insight on this board welcome. I was interested in adding additional optical drives on independant cables so I can read and write to and from them at the same time, whereas typical two-port IDE is used for drives and Hard disk
