I thought I would just post this to save others a few hours of troubleshooting since there’s almost no documentation on this card to be found anywhere.

If your base address for the soundcard is 220, the cd interface is at 230, which you’ll need to tell slcd.sys where to look for the drive in the config.sys.

Most other interface cards for the sony interface drives put the address up in the 300 range (usually 320), but for whatever reason, this card puts it at 230. I haven’t tested it, but I’d assume it’s a +10 offset from whatever you have the base address set at, but I’m just happy to have it working!
