Certainly disk2 looks like it has a filesystem on it, since there are
blocks which appear to be 16 byte directory entries, presumably
inode number and 14 char name.

I don't know about historical sources of the time.
The availale Coherent source has a few files with z8001 in their name:
$ gzip -dc ~/Downloads/mwc-COHERENT-Source.tgz|tar tvf - |fgrep -i z800

I looked inside the first one, and it gives this set of files, being the library for the syscalls:
$ ls z8001/
_brk.s chroot.s getegid.s link.s pause.s signal.s umount.s
access.s close.s geteuid.s lock.s pipe.s sload.s unique.s
acct.s creat.s getgid.s lseek.s profil.s stat.s unlink.s
alarm.s dup.s getpid.s mknod.s ptrace.s stime.s utime.s
bpt.s execve.s getuid.s mount.s read.s suload.s wait.s
chdir.s fork.s halt.s mpx.s sbrk.c sync.s write.s
chmod.s fstat.s ioctl.s nice.s setgid.s times.s
chown.s ftime.s kill.s open.s setuid.s umask.s
I've not explored any further, but if the kernel source isn't there, I rather suspect
the 286 kernel source could be beaten in to some sort of shape to work on the z8000.
There some RCS files in there if you wish to explore further.
That still leaves you with having to come up with drivers, but there do seem to be
(some) technical docs available for the machine.
