I have SORD FDOS and CP/M-68k for the M68, but not sure when I'll be able to fire up my working M68 to get them copied. I've never seen the P-System for the M68, although it was advertised as available.
If you haven't already, check
https://www.sord.co.nz - the site is incomplete and wildly out of date, but there's info about my SORDs there!
