Quadric Surface Plotter · Paul Mitchell

Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB and Toolkit II 2.32. Selected a paraboloid with X=30, Y=150, Z=90 and visible axes: plotting completed. Other surfaces were not tested. Basic functional check in sQLux, not a complete test or a test on physical QL hardware. Audio not tested. ROMs are not included.
