Maybe you would notice > the 0.76mm difference for a 40-pin socket and chip. 0.4 mm is the approximate worst-case misalignment (~0.76/2) of the four outward pins if one aligns the chip cleverly ie. to the middle of the socket. > Maybe the ignorant could just dismiss the difference as Soviet > tolerances :) Rumour has it that Russia redefined the railway gauge, > extending the track width by 3mm, because it was cheaper than rebuilding > all tracks after the collapse of the Soviet Union. Wikipedia has an interesting article about the Russian rail gauge (haven't known, for example, that Finland uses a broad gauge of similar inheritance). They indeed mention a redefinition of the gauge size from 1524mm (5ft) to 1520mm starting from the '60s. Levente Message was sent through the cbm-hackers mailing listReceived on 2014-06-02 16:05:12
