Assembly x86 Microprocessors

8086/8087 (1978) The 8086 was the original x86 microprocessor, with the 8087 as its floating-point coprocessor. The 8086 was Intel's first 16-bit microprocessor with a 20-bit address but, thus enabling to address up to 1 megabytes, although there was a limit of 640 kilobytes of RAM. this limitation is still presend in modern CPUs, since they all support the backward-compatible "Real mode" and boot into it. 8088 (1979) After the development of the 8086, Intel also created the lower-cost 8088.
