IBM Personal Computer XT 5160

The IBM PC XT extended the original PC with a hard disk, more expansion slots and a strengthened power supply. Its 8088 processor remained compatible with the growing PC software library.

The XT configuration became a widely copied standard for business PCs and established hard-disk storage as an expected feature.

Notable Features

• A 10MB hard disk distinguished the original XT configuration.
• Eight ISA slots made it more expandable than the 5150.

Historical Significance

• The XT configuration became a widely copied standard for business PCs and established hard-disk storage as an expected feature.

Collector’s Notes

• Original IBM documentation, matching display and keyboard, and an unmodified configuration add historical context.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
