Old Computers - rare, vintage and obsolete computers:"The Model 5100 is IBM's first microcomputer, i.e. not a mainframe, and is also considered the world's first portable computer. Although at 55-pounds, it might best be described as "self-contained" rather than "portable".
There were very few other computers available at the time, and nothing even close to the capabilities of the 5100. It is a very complete system - with a built-in monitor, keyboard, and data storage. It was also very expensive - up to US$20,000. It was specifically designed for professional and scientific problem-solvers, not business users or hobbyists. "
