Contour Plotter — Dormand

Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB emulator RAM and Toolkit II 2.32. Evaluated the built-in function on an 11×11 grid over −1 to 1 and drew contours at 0.25, 0.5 and 0.75 with axes and legend. Printer output was not tested. Basic functional check in sQLux, not full validation or a physical-hardware test. Audio untested. ROMs are not included.
