當年讀書要學設計，必須自己動手製作。樓下有個小車間，通過培訓可以自己在車間動手。
裡面就有金剛砂飛輪，車間內必須戴防護設備，尤其護目鏡。
無論什麼堅硬的材料，到了金剛砂飛輪，向下一串火星冒出，馬上磨平。
另外，大學一年級時候學的Z80是作為匯編語言的單板機而用，估計當年就沒啥用。現在更是毫無意義。
早就過時了幾個世代。
Motorola 68008
The Motorola 68008 is an 8/32-bit microprocessor introduced by Motorola in 1982.
It is a version of 1979's Motorola 68000 with an 8-bit external data bus, as well
as a smaller address bus. The 68008 was available with 20 or 22 address lines
（respective to 48-pin or 52-pin package) which allowed 1 MB or 4 MB address space
versus the 16 MB addressable on the 68000. The 68008 was designed to work with lower
cost and simpler 8-bit memory systems. Because of its smaller data bus, it was
roughly half as fast as a 68000 of the same clock speed.[citation needed] It was
still faster than competing 8-bit microprocessors,[dubious – discuss] because
internally the 68008 behaves identically to the 68000 and has the same microarchitecture.
Motorola ended production of the 68008 in 1996。
