 The Tandy 1000 series was an attempt to enter in the IBM compatible world. The 1000 EX was a PC-compatible school and home computer that runs 50 % faster than any other PC. The Intel 8088 microprocessor-based system runs most MS-DOS software. Features that helped the machine sell well on the market are classroom Network 4 network, price, DeskMate software, and telecommunication software. It was also possible to install other high resolution graphic cards for AutoCAD and drawing applications.
