The spacing of the sockets on the Microtan motherboards are multiples of 0.2" so that they are compatible with the guide rail spacing in (old?) standard 19" racks. For the Mini-motherboard the spacing is 1.4". On the full-sized Tangerine motherboard they are 0.8" apart except between the CPU and TANEX boards which are 2.2" apart.
