Interesting 8-bit SB clone board

It's quite horrid Very noisy, and doesn't work in 386 (FM is broken, half the channels are missing or such). Plays fine in a 10MHz XT, and Mark Cox's MOD player is able to play something remotely resembling a .mod... Has anyone seen something like this? Obviously it's a knock-off from the far end of the silk road.

Some chips read "SM64 JCBH" and there's an SZ1208-CD. Some hard-working soul "soldered" a CD-audio connector onto the back side of this one (not pictured, 18+)

SM64 JCBH seems a pair or the OPL-2 (YM3812) clone, SZ1208-CD is a i80c51 made by MHS (note an Intel's copyright)
8-pin DIP SM65 JCBH is a YM3014B DAC clone.

Since it has two OPL-2 chip it seems it's a SB PRO (not SB PRO 2)

That card edge connector is all sorts of oxidized and tarnished, which could have something to do with it not behaving.

Try using some phosphor corrosion remover or a pencil eraser across the contacts to see if it works any better.

It's missing quite a bit of logic if it's supposed to be a clone of the Sound Blaster Pro CT1330 - though to be fair, that could be logic that's driving the CD interface.

Both cards gave 25 ICs ;-) and the clone card does not have an IDE interface...
SMD for the win!
