  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.
