有時很羨慕現在的年輕人,
因為從出生起就享受著網路及手機的便捷,
在那個沒有網路, 手機及pc的年代裏,
要學電腦就要從終端機及大型電腦的操作開始.
就在那時學校買了新的電腦系統: vax-8530

(VAX 8000 series index)
是的, 您沒看錯!
1個CPU及最高320MB的記憶體,
這種規格連現今的PS4都會笑吧!
在那年代稱為迷你電腦,
使用靠terminal終端機登入及輸入指令,
這台電腦的本體擺在一間終年有冷氣的大房間
聽說學校花了百萬的資金購買,
每次從房間這端走到另一頭時總帶著敬畏的心,
好處是不用打紙卡了,
只需在螢幕前用鍵盤輸入各項指令,
再等待電腦回應即可...
