The tests were complicated by the fact that Chinese manufactured transitors are of very low quality. The ones already on the board had to be desoldered, new ones tested and placed. Due to a stupid mistake 4 PCB traces are missing, but that can be fixed quickly and proceed with tests. The software will be modified as the second prototype uses different bit ordering. The original was rather counter-intuitive.
