Hmmm... No manuals, eh?  Well, try your dealer for those.  We have them, but
one with each board.... no extras unfortunately.

As for hacking the traces and the like, someone just posted an article on
just that subject.  It should still be around.

The WD1006V/SR2 is a hard/floppy controller.  The older WAH boards aren't
all surface mount from what I understand, the VSRx series is.  I don't know
all the differences between them as far as jumpers and the like go.

There is also a SR1 board which is the same but less floppy control.
