有冇諗過一粒CPU係點運作？
讀大學嗰時都有學過 computer systems，做過幾個bit既 adder。雖然對 CPU 個 basic design有啲 concept，但係冇諗過自己可以做一個function 既CPU 出來。
Jon 用咗US$60（我估唔止）買咗 281 個 relay，design 一個CPU出來。可以每秒行 30 - 50 個 instruction。而家買粒 dual core 既 CPU 都係HK$400-600…
佢話如果切個 x86 instruction set 既 relay CPU，boot 起 Windows XP 大約要 幾百年！

Why on earth build a relay computer when there are already computers over a hundred thousand times faster? Well, for two reasons: to prove that silicon is not magic and because I want to.
