Processors ranged from the 486DX2-50, 486SX-25, 486DX4 -100 to the Pentium 200 and in case of the Models 360 and 365 the Pentium Pro. 486 models had a selectable bus architecture (SelectaBus) through a replaceable riser-card, offering the choice of either VESA Local Bus / ISA or PCI /ISA. Within the 300 series the following models appeared:

The Model 70 486 was introduced in December 1989 in two variants: the Model 70 486-B21, with a 120-MB ESDI hard drive, and the Model 70 486-B61, with a 60-MB ESDI hard drive. Both ran the Intel 486 processor at 25 MHz and were essentially rebadged variants of the Model 70-121 and Model 70–061 with the 486/25 Power Platform preinstalled. [ 22 ]

The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386 . It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386 .

Compatible processors for 486 PC have been produced by multiple brands, which include IBM, Texas Instruments, AMD, Cyrix, UMC, Compaq, and SGS Thompson. A lot of variations were clones, while others used advanced instructional sets.

Intel CPU 486 首次上市時間約是 1991 年 6 月的前後，之後 486 歷經數個型號的版本更迭 (SX DX 之類，再細分還有 CPU Clock Rate 的高低之分)，直到筆者退伍之際，也就是 1994 年 5 月 31 日，Intel CPU 的最新型號仍是 486 開頭。
