The ZX81 Companion, like other ZX81 books, is totally applicable to the TS1000. It begins with a chapter on graphics techniques. First the screen field is explained. Then PLOT and UNPLOT are used to develop the basic components in graphics: drawing straight lines, using triangles, circles, parabolas, and ellipses, and moving a point around the screen. After the PRINT AT instruction is discussed, it is combined with INKEY$ to create realtime programs.
