I just noticed that the 32V tape on the TUHS Unix Tree page includes a directory “slowsys”:
https://www.tuhs.org/cgi-bin/utree.pl?file=32V/usr/src/slowsys

This “slowsys” directory appears to contain the 32V kernel with a pure swapping architecture. 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 — 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=32V/usr/src/sys contains the scatter loading, partial swapping version of the 32V kernel.
