I was speaking to Drussian a week or so ago about his incoming Katana kit. He'd managed to get a really good deal on eBay. Regrettably when the unit arrived it had been very badly packaged by the previous owner. Infuriated with this he immediately decided it wasn't worth proceeding with this particular unit, which I then traded. When we spoke it was clear that the facade had been damaged and the dipswitch section had been knocked off. Today the Katana arrived in my mitts and the damage is slightly worse, but thankfully limited to 1 PCB on the facade of the unit. From what I can gather, the unit must have been dropped heavily onto its left hand side, which forced the frame upwards cracking the edge of the facade and pushing the rotary switch upwards and forcing the dipswitch section to literally dump all the little switches either inside the unit or into the packaging. When I took the unit to bits I found the last missing piece! So, the legs of the rotary switch have snapped and I am not 100% sure there is enough left to solder them to recreate the connection to the PCB. Secondly, these little ALPS dipswitch sections are as fragile as all hell. The surround is missing and although I now have the top and 4 switches there is little hope of them remaining held down against the metal contacts. So, job 2 is finding a supplier of spare dip switches. These should do the trick I guess: http://www.omroncomponents.eu/home/products/Switches/DIPSwitches/default.asp?ComponentID=54292&SourcePageID=52194#1 Other than that, it looks in good condition internally and should work with a bit of luck. Is the laser a standard one found in the retail units? Or is it akin the the Nintendo NR reader, set differently?
