When testing a modified board a while back I discovered that I had forgoten one important ingredient and step in this recipe. I've just updated http://stuge.se/m57sli/ and added a photo of the finished mod while I was at it.

For the better modification, you also need: 2x 0402 4k7 chip resistors (1k is OK too, 10k does not work!) 2x 0603 100k chip resistors 2x SOT-23 BC847C transistors
Add:
1cm AWG 30 wire (but get some extra so there is some to work with)
Better: NOTE: Switch wires can be rather long. Several meters has been tested. 4. R90,R91: Populate 0402 4k7 resistors
Insert:
5. Q2,Q43: Solder 5mm or so of AWG 30 wire between Q2-2 and Q2-3. Solder another wire between Q43-2 and Q43-3.
I am happy to sell boards pre-modified with the better modification. Unfortunately I cannot offer these boards to consumers in all EU member states because of EU environmental regulations, but many are OK.
I've made a table showing which states I can sell to on the web page too.
