The Bill and Melinda Gates Foundation has pledged $15m (£8.54m) to the Computer History Museum in California.
The gift is the museum's largest and will be used to create an interactive exhibit, tracing the computing revolution and its impact.
The Gates' donation boosts a $125m (£71.2m) fund-raising campaign to set up a long-term endowment.
The institution still needs another $50m (£28.4m) to reach its target.
It wants to use the funds to have more exhibits, have longer opening hours and set up educational programmes.
I think this is a really good idea, not only in our life time have WE seen so many changes, but think of future generations. We laugh at what we had, how long before they will be laughing at OUR LACK of knowledge
