== Features ==
The XT was regarded as an incremental improvement over the PC and a disappointment compared to the next-generation successor that some had anticipated. Compared to the original IBM PC, the XT has the following major differences:<ref name=":0">{{Cite magazine|url=https://archive.org/details/byte-magazine-1983-05|magazine=Byte |volume=8 |number=5 |page=520 |title=IBM Unveils Top-of-the-Line Personal Computer |date=May 1983}}</ref>
* The number of expansion slots was increased from five to eight
* Base RAM was increased to at least 128 KB
* 2x32KB ROM ICs replace the previous 5x8KB ROM ICs
* A 10 MB hard drive was included
* [[IBM PC DOS#PC DOS 2.x|PC DOS 2.0]] was included
* The [[DIN connector#Analog audio|5-pin DIN]] for the cassette interface was removed

In 1986, the 256–640 KB motherboard models were launched, which switched to half-height drives.
Submodels 268, 278 and 089 came with 101-key [[IBM PC keyboard|keyboards]] (essentially the IBM Model M, but in a modified variant that used the XT's keyboard protocol and lacked LEDs).
Submodels 267, 277 and 088 had the original keyboard, but 3.5" floppy drives became available and 20MB Seagate ST-225 hard disks in 5.25" half-height size replaced the full-height 10 MB drives.
