當年，中國的半導體整體水平和美國差遠不止5年，在計算機係統上差10幾年以上。

The world's first single-chip fully 32-bit microprocessor, with 32-bit data paths, 32-bit buses, and 32-bit addresses, was the AT&T Bell Labs BELLMAC-32A, with first samples in 1980, and general production in 1982.

當時用得最廣泛的是MC68000. MC68000 is a 16/32-bit CISC microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. 

我是中國第一批軟件畢業生。在83年就用過MC68000小型機，是國內第一批進口的。
