notes: label: Description
content: The IBM PC-AT was introduced in 1984. The "AT" stood for "advanced technology." The machine was the first upgrade from IBMs original PC architecture introduced in 1981 (the XT expanded storage options, but not the processor, bus, chipset, etc.) The ATs used the Intel 80286 processor chip. The first ATs were released with a conservative 6 MHz processor which was quickly upgraded to 8 MHz. The BIOS allowed for the definition of aftermarket hard drives. The AT also introduced the 1.2 MB high-density 5.25" floppy drive which became an industry standard until the advent of 3.5" disk drives.
