It costs only 4004 ￥ 3,000 in cash, today, in 1972, 8008 Intel is to create a much stronger than 4004, that price is from 14,004 10 times. The microprocessor can use your computer, in the heart of numerous applications.
Beginning of the year 1970, will be used PCs, only fans. The first "hobby" is the cash Altair 8800 computer, which currently costs EUR 900. The same performance of the PC 1950 is a price of 100 million years ago.
