Tandy Plans to Build IBM PS/2 Clones
Tandy Corp. holds a press conference in New York to announce its plans to build clones of IBM's PS/2 system computers. The conference comes on the heels of IBM's announcement that it would license patents on key PC technologies, a move that signaled its willingness to let other companies clone its machines. Within five years, IBM clones became more popular than original IBM machines themselves.
