# Multi-Tasking on the Timex-2068 Using Z80 Interrupt Mode 2

In-depth technical article on implementing Z80 interrupt mode 2 on the TS-2068 for multi-tasking. Explains the 257-byte interrupt table, vector table, and service routine structure. Author used the technique in his machine code word processor to run a print spooler, input buffer, clock/calendar display, and clock display simultaneously. Includes assembly code listing.
