Timeline: Dell since 1984, a roller-coaster ride

Twenty-nine years after its founding, iconic computer maker Dell Inc agreed to a $24.4 billion deal to go private on Tuesday. The $13.65-per-share deal for the world's third-largest computer maker involves chairman Michael Dell, private equity firm Silver Lake and Microsoft Corp.

Here is a look at Dell's 28-year journey:

1984 - Michael Dell, a 19-year-old, pre-med college freshman starts selling computers built from stock components out of his dorm room at the University of Texas in Austin. He later drops out to focus on the business he names "PC's Limited."

1985 - PC's Limited creates a 10-megabyte personal computer, the Turbo PC, with a pricetag of $795, undercutting IBM's costlier machines. The business expands to set up its first international subsidiary two years later in Britain.

1988 - PC's Limited changes its names to Dell Computer Corp and goes public, raising $30 million and increasing its market capitalization to $85 million. Its shares debut at $8.50, or a cumulative split-adjusted price of 9 cents.

1989 - First laptop computer, the 316LT, goes on sale.

1990 - Dell opens a manufacturing center in Limerick, Ireland, to serve Africa, Europe and the Middle East.

1992 - Company debuts on Fortune 500, making Michael Dell the youngest CEO on the list at the time, at age 27.

1995 - Dell goes global, expanding to Asia, Japan, Europe and the Americas.

1996 - Dell.com launches, hits $1 million in daily sales in six months.

1997 - Second manufacturing center in Texas opens, ships its 10-millionth PC.

2000 - Dell.com's online sales hit $40 million a day.
