It is not quite the kernel = described in the well known 32V paper, as it seems to have advanced from = a fixed 192KB image size mapping to a more variable mapping of up to 1MB = =E2=80=94 but otherwise the code appears to be as described in the July = 1978 paper. The directory https://www.tuhs.org/cgi-bin/utree.pl?file=3D32V/usr/src/sys= contains the scatter loading, partial swapping version of the 32V = kernel. Paul =20=
