The Osborne 1 was the world's first truly portable computer. It was really innovative, in that the main unit and keyboard folded up together for easy carrying: folded up it had a similar weight to a portable sewing machine. It was invented in 1981 by Adam Osborne (1939-2003).
I have just learned that Adam was the son of Arthur Osborne (1906-1970) a British academic and writer who lived for a time in India and was a follower of Ramana Maharshi. His family home adjoins that of my friend in Tiruvannamalai, who I hope to visit again very soon.
According to Wikipedia, Adam wrote a bestselling book about his experiences together with John C. Dvorak, Hypergrowth: The Rise and Fall of the Osborne Computer Corporation. In later life, he returned to India, where he lived in Kodaikanal, Tamil Nadu.
Never heard of the Kaypro. There are plenty of images on the internet of the Osborne 1. Of course anything that included a CRT had to be a bit bulky, even if everything else could be made smaller. The Osborne had a really tiny screen (which lacked any kind of graphics ability)
