Intel 80286

(processor)
(Or "286", "i286") A microprocessor developed by Intel. THe 80286 processor has a 16-bit data bus and incorporates a memory management unit that allowed a limited amount of multitasking. The 80286 only has a segmented MMU while the later processors add a paged MMU "behind" the segmented one.

The 80286 was the processor in the IBM PC AT personal computer.

This will cost about $800 more than an AT with an 80286 microprocessor, but it will operate three to 10 times faster.
Intel's list of the top fifty anticipated applications for the 80286 microprocessor, the successor to the 8088 microprocessor chosen by IBM for its first personal computer, did not include the personal computer (Cogan and Burgelman, 1990).
OCLC has announced that it will reduce prices by almost 20 percent on all models of the M310 Workstation (a 16-bit 80286 microprocessor running at either 8 or 12.5 MHz with 1MB RAM, a 1.2MB 5 1/4 floppy, a 40MB hard drive, an enhanced PC keyboard, two serial ports, two parallel ports, and a VGA adaptor and a monitor).
While 386 PCs already run OS/2 (the operating system developed by IBM and Microsoft as a successor to MS-DOS), the current version is just as appropriate for the PC/AT's single-tasking 80286 microprocessor and 16-bit architecture as for the more powerful 386.
The AT, using the Intel 80286 microprocessor at speeds of 6 to 8 MHz, is about two to three times faster than a PC or XT.
The consequent first expense of this law office is a high level PC (based on at least an 80286 microprocessor).
The PC and XT use an 8088 or 8086 microprocessor, while the AT uses the 80286 microprocessor. The type of microprocessor determines the internal structure and speed of the computer and what kind of programs can be run.
The installed base of x86 microprocessors created by IBM's success in the PC market segment (with Intel's 8088 and 80286 microprocessors) had significantly and fortuitously shifted bargaining power in Intel's favor.
