People who examined the IBM 7552 Gearbox, ostensibly a factory-hardened version of the AT, notice something odd about the unit's bus: It had more bus lines than could be accounted for by the AT bus. The extra lines turned out to be the 16-bit Micro Channel. Nobody at IBM said anything about it at the time, because PS/2 hadn't yet been introduced.}}
