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.
当时用得最广泛的是MC68000. MC68000 is a 16/32-bit CISC microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector.
我是中国第一批软件毕业生。在83年就用过MC68000小型机,是国内第一批进口的。
