TANDY 1000 TL/3 (250-1603) Math Coprocessor Faxback Doc. # 1246 Note: The 1000 TL/3 requires a 8MHz, 80287 math coprocessor. Refer to Faxback Doc. # 9002 for Catalog Number. Note: Refer to Faxback Doc. # 1248 for installation location on the Main Logic Board. The installation of a math coprocessor will speed up applications requiring many arithmetic calculations, such as Spreadsheets or CAD packages. The coprocessor takes over the mathematical processing which in turn frees up the cpu for other tasks. Note: Incorrect orientation or installation of the coprocessor can damage the coprocessor or the socket. Radio Shack Service Center tech- nicians will install optional devices if you choose not to do so yourself.
