With a production code of mid-1985, this is the oldest 286 in my collection. Back in '85 this 6MHz 286 was an expensive part, despite that the 286 was available for 3 years already.
The 286 had various performance improvements which made it a lot faster than the original 8088/8086. The mathematical DOSBench shows an incredible 32 points compared to the 18 points of an 8MHz 8086 which is almost twice the score despite the 2MHz lower clock-frequency.
