Buffalo Shield revision for B3SE

As I said, I will release a new revision of the Buffalo shield that will have better support for the B3SE.

Since that will probably take some time, in the meanwhile, this is what B3SE (or 32s or II) owners should do to their shields in order to support the B3SE:


The idea is to connect the photosensor side of one of the optoisolators directly to the IP_S header on the B3SE. In order to do that, you will have to cut one trace on the PCB and solder directly onto one of the optoisolator’s pins. That’s pretty much it.

On the new revision of the shield there will be a jumper where you have to cut the trace plus an extra pin so that you don’t have to solder onto the isolator’s pin.
