I could guess but, what is a Z1000? A Z1000 is a multiprocessor Unix box. The one I've got is running Xenix, but since SCO is now shipping Corollary's MPE (Multi Processing Extensions), you can now run SCO Unix on it. You forgot _Z1000upstart. I would guess that they're for controlling the built-in UPS. Unplug the sucker from the wall and you get no reaction, other than that it runs /etc/powerfail, which tries to kick everybody off and shut the machine down. My biggest complaint with /etc/powerfail is that it never checks to see if it got AC power back. Perhaps a little hacking with the above functions will let me fix that, eh? I've heard rumors that Zenith was the first to use Corollary's technology, which is believable. Unfortunately, they're fairly close-mouthed about the product. That's too bad, because it's one heck of a lot of machine. The one I've got has four processors, 32 MB of memory and 600 Meg of disk. That's really not enough disk, but Zenith donated it to us, disk and all.
