Intel 8086 -1

This processor was manufactured in 1984 and is the oldest x86 CPU in my collection. It runs at 4.77MHz and is notable as the processor used in the original IBM PC. The first 8086 was introduced in 1978 and was sold for quite some time. Eventually most XT's were equipped with 8088 processors due to a less complex, 8-bit, motherboard. In late 80'ies the 8086/8088 was obsolete and the 286 processor was considered the slowest option in new PC's.

Because the 8086 (and 8088) is the first x86 CPU it is still popular under enthusiasts who like legacy hardware. With efficient programming it's possible to use the 8086 for a lot of tasks. Enthusiasts wrote programs to use FTP- and IRC-clients running on DOS, graphical web browsers and modified the original Wolfenstein 3D source code and let it run on the 8086.
