The capacity (bits) of the largest DRAM (dynamic random access memory) chips
commonly available at retail has increased as follows:

Year Bits
1971 1,024
1980 64,000
1987 1,024,000
1993 16,384,000
1999 256,000,000
2000 512,000,000

Regress the DRAM capacity on year. Is there anything unusual in the residual plot?
