Opera 1 for computers

The research browser that started it all. Opera 1.00 was written by Jon Stephenson von Tetzchner and Geir Ivarsøy at Telenor, before they founded Opera Software later in 1995. It was never sold, but it was shown publicly at the WWW '95 conference in April 1995, and it already had the idea that defined early Opera: several pages open at once, as windows inside one application.

What was new

• Shown publicly at the WWW '95 conference, April 10–14, 1995
• Several pages open at once, inside a single window (MDI)
• Multiple home pages, a hot list and a keyboard interface
• Kept in the archive as a research curiosity: it is not an installer but a zip of the program
