ABSTRACT:
In an interactive network board, method and apparatus for multi-tasking independently executable programs, makes use of a ROM, disposed on the board, for storing (i) a monitor program, and (ii) first and second independently executable programs. The first and second programs each include a relinquish command. A processor is disposed on the board for downloading the monitor program and the first and second programs from the ROM to a RAM. The processor executes the first program in RAM until the first program relinquishes control. The monitor program then begins execution and stores in the RAM information which indicates the execution state of the first program. The second program then begins execution in RAM until the second program relinquishes control. The monitor program then recommences execution to store in the RAM information which indicates the execution state of the second program. Thereafter, the monitor program recommences execution of the first program, preferably from the point at which the first program relinquished control.
