The IBM PS/1 was a brand for a line of personal computers and was IBM's return to the home market in 1990, five years after the IBM PCjr. It was replaced by the IBM Aptiva in September 1994.

The IBM Personal System/1 was a compact, easy-to-use computer primarily for use in the home. Its developers wanted a computer that would be easy enough for the novice to use and powerful enough for the more advanced user, flexible enough to meet the needs of every family member, a snap to set up, and priced economically (ranging from $999 to 1,999).

Making its debut on June 26, 1990, the PS/1 fit the bill in every respect as a serious machine that was simple to use. New users could simply take it out of the box, plug it in and turn it on with a touch of a button. Colorful graphics on the first screen guided users to the PS/1's built-in software and to online services, eliminating the need to understand computer language. On the other hand, the PS/1 had the power and capacity to help run a home-based business or connect users with their office. The compact system unit was powered by the Intel 80286 microprocessor, with either 512K or 1 megabyte of memory. For storage, consumers could choose initial models with either a 1.44 MB diskette drive or diskette drive plus 30 MB hard disk. The system unit also included a built-in 2400-bits-per-second modem. A variety of options were available for additional expansion and flexibility.
