The first portable computer was known as Osbone 1 which was developed in 1981.
This heavy and cumbersome machine used CP/M operating system which means Control program monitor who was commonly used in 1970s before the MS-DOS wiped it out after the introduction of the IBM PC in the year 1981.
Finally professionals were able to move around with their data and information on a portable computer. The only problem was that it had to be plugged on an electric socket since it could not use batteries.
Kypro 11 was developed as perfection rather than a competitor of Osbone 1. It had twice the size of Osbone 1 when it came to the screen features and when purchased new, it came with a software bundle and it had twice the storage capacity and double density floppy drives as opposed to that of Osbone 1.
Next in line came the Bondwell 2 which was not released until 1985 which came as a result of the operating system decline of CP/M. The Compaq was introduced in 1983 at a time when standard computer platform was looked upon IBM Personal Computer.
Other laptop models that followed Epson PX-4, the NEC PC 8401A,PX-8 and NEC PC-8500. None of these four units came with standard hard disk or floppy although they made use of the CP/M modified system in the Rom.
