first, hi to all.
i like this forum, it is very interesting for people (like me) have passion for old computers and hardware.
After several searches, I managed to have a sound canvas (SCB-55 doughter-board).
I tested using a sb16, it works well (there is the problem of hanging notes due to sb16).
But if i look the card, i see one track cut (open) in the PCB in the rear, and in the front another track open and two wires.
i don't know why this customization of the board.
does anyone know why?
it is very strange.

that interesting, reminds me of modern day sound card mods for better sounds quality. how ever i think this was modded for different purpose maybe repair or compatibility of course that is just a wild guess. found this interesting, figured i'd toss my 2 cents in.

Judging by the number on the PCB (the '2' behind the 'M'), this is an early revision of the SCB-55. I have read somewhere that early revisions of this board had the left and right channels reversed, so this cut and these patches might have a way to correct that.

Edit: yes, a look at http://en.wikipedia.org/wiki/Creative_Wave_Blaster confirms that pins 20 and 24 are the ones for the right and left output channels.
