The Tandy 2000 was a personal computer introduced by Radio Shack in late 1983 which used the 8 MHz Intel 80186 microprocessor. By comparison, the IBM PC XT (introduced in March 1983) used the older 4.7 MHz 8088 processor, and the IBM PC AT (introduced in 1984) would later use the newer 6 MHz Intel 80286. Due to the more efficient design of the 80186, the Tandy 2000 ran significantly faster than other PC compatibles on the market, and slightly faster than the PC AT.
On the surface the computer was quite the catch: The “T-2000” featured new instructions and new fault tolerance protection over the TRS-80 and COCO lines. Tandy built the 2000 with advanced color graphics, Intel 16bit processing at 8 Mhz and 2 720K 5.25” Floppy disks; and a CPU that was out performing even the 80286 computers of the time! It was a robust computer with excellent features but that 80186 CPU would come back to haunt it. The Tandy 2000 by many was considered the first AT style computer in North America, a bold and risky move by Tandy.
