The 386 was the first significant microprocessor to be single-sourced.

The Intel 80486 microprocessor ( alias i486 or Intel486 ) was a higher performance follow up on the Intel 80386.

Intel's i486SX was a modified Intel 486DX microprocessor with its floating-point unit ( FPU ) disconnected.

, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, IBM POWER, and SPARC.

Intel was willing to undertake a very large development effort on IA-64 in the expectation that the resulting microprocessor would be used by the majority of enterprise systems manufacturers.

In about 1991, Software Components Group was acquired by Integrated Systems Inc. ( ISI ) who further developed pSOS-now restyled pSOS +-for other microprocessor families, by rewriting the greater part of it in C. Attention was also paid to supporting successively more integrated development environments, culminating in pRISM +.

When the IBM Personal Computer was being developed, DR was asked to supply a version of CP / M written for the Intel 8086 microprocessor as the standard operating system for the PC, which used the code-compatible Intel 8088 chip.

After Intel introduced the 8008 8-bit microprocessor, Fairchild developed the Fairchild F8 8-bit microprocessor, which had an unusual architecture and was not a great market success.

Paul Allen had developed a program that could completely simulate a new microprocessor system.

It was developed for a Japanese calculator company, Busicom, as an alternative to hardwired circuitry, but computers were developed around it, with much of their processing abilities provided by one small microprocessor chip.
