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 -rw-r--r-- 0 steve staff 6521 6 Feb 1991 romana/relic/d/lib/libc/sys/mch/z8001.tar.Z drwxr-xr-x 0 steve staff 0 14 Jun 2003 romana/relic/d/lib/libc/stdio/z8001/ -rw-r--r-- 0 steve staff 268 9 Nov 1984 romana/relic/d/lib/libc/stdio/z8001/fgetw.c -rw-r--r-- 0 steve staff 169 9 Nov 1984 romana/relic/d/lib/libc/stdio/z8001/fputw.c -rw-r--r-- 0 steve staff 340 9 Nov 1984 romana/relic/d/lib/libc/stdio/z8001/getw.c -rw-r--r-- 0 steve staff 231 9 Nov 1984 romana/relic/d/lib/libc/stdio/z8001/putw.c -rw-r--r-- 0 steve staff 4906 6 Feb 1991 romana/relic/d/lib/libc/gen/mch/z8001.tar.Z drwxr-xr-x 0 steve staff 0 14 Jun 2003 romana/relic/d/bin/diff/z8001/ -rw-r--r-- 0 steve staff 8445 2 Nov 1984 romana/relic/d/bin/diff/z8001/diff1.c -rw-r--r-- 0 steve staff 7767 23 Mar 1990 romana/relic/d/bin/diff/z8001/diff2.c -rw-r--r-- 0 steve staff 92 8 Jul 1985 romana/relic/d/bin/diff/z8001/Readme -rw-r--r-- 0 steve staff 17512 7 Mar 1991 romana/relic/d/bin/db/mch/z8001.tar.Z -rw-r--r-- 0 steve staff 13929 7 Mar 1991 romana/relic/d/bin/db/mch/z8002.tar.Z -rw-r--r-- 0 steve staff 21823 6 Feb 1991 romana/relic/d/bin/as/mch/z8001.tar.Z -rw-r--r-- 0 steve staff 19275 6 Feb 1991 romana/relic/d/bin/as/mch/z8002.tar.Z -rw-r--r-- 0 steve staff 6521 6 Feb 1991 romana/relic/b/lib/libc/sys/mch/z8001.tar.Z drwxr-xr-x 0 steve staff 0 14 Jun 2003 romana/relic/b/lib/libc/stdio/z8001/ -rw-r--r-- 0 steve staff 268 9 Nov 1984 romana/relic/b/lib/libc/stdio/z8001/fgetw.c -rw-r--r-- 0 steve staff 169 9 Nov 1984 romana/relic/b/lib/libc/stdio/z8001/fputw.c -rw-r--r-- 0 steve staff 340 9 Nov 1984 romana/relic/b/lib/libc/stdio/z8001/getw.c -rw-r--r-- 0 steve staff 231 9 Nov 1984 romana/relic/b/lib/libc/stdio/z8001/putw.c -rw-r--r-- 0 steve staff 4906 6 Feb 1991 romana/relic/b/lib/libc/gen/mch/z8001.tar.Z 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. DF
