Matrix Equations — Jan Håkansson

Floppy IMG derived from archived files. Mount as FLP1 and boot using Minerva 1.98a1 ROM, 640 KiB and Toolkit II 2.32. Corrected determinant sign handling. Verified two row-permutation determinants equal -1 and a three-equation solution (1,2,3). Original retained. Basic functional check in sQLux, not a complete test or a test on physical QL hardware. Audio not tested. ROMs are not included.
