The 80286 went into the IBM PC AT. The XT was the one with the 8088 chip. However after the AT 80286 came out, it was possible to get an upgrade card for the XT 8088 that was essentially an 80286 and motherboard on a card. It was like brain transplant for your computer. It wasn't as fast as running a real AT but it was cheaper and a lot faster than the 8088.
