IBM PC AT
AT
PC AT
<computer> ("Advanced Technology") A version of the {IBM PC},
released in Aug 1984 with an {Intel 80286} processor, a 16-bit
{bus}, a medium-speed {hard disk} and a 1.2 {megabyte}
{floppy} {disk drive}. It had a larger case than the PC,
which allowed it to accept "{tall cards}".
The AT keyboard corrected the PC's non-standard placement of
the {return} and left shift keys but shortened the {backspace}
key, making it harder to reach.
