Portable computer, 1983, Tandy. The TRS-80 Model 100 was the first commercially successful notebook computer, designed by Kyocera in Japan with software written by Microsoft (Bill Gates says it was the last product for which he wrote much of the code himself). It runs for about 20 hours on four AA batteries, has a full keyboard and an 8-line LCD, and its ROM contains BASIC, a text editor, a terminal program with a built-in modem, an address book and a diary. About six million units of the Model 100 and its siblings (NEC PC-8201, Olivetti M10) were sold, largely to journalists.
