EIGN — autovalori della matrice di Hilbert

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. For n=3, computed eigenvalues of z(i,j)=1/(i+j+1): 0.6570514, 0.01892631, 0.0002127372. Independently checked these numeric results. Basic functional check in sQLux, not full validation or a physical-hardware test. Audio untested. ROMs are not included.
