By contrast, the ASCC's "successor" -- the IBM Selective Sequence Electronic Calculator (SSEC) of 1948 -- contained 21,400 relays and 12,500 vacuum tubes. Its electronic arithmetic circuits could perform 14-by-14 decimal multiplication in 20 milliseconds, division in 33 milliseconds and addition or subtraction of 19-digit numbers in only 0.3 milliseconds. The SSEC was more than 250 times faster than the ASCC.
