Zenith Data Systems is currently shipping the Z-1000, a 386 multiprocessor
based on technology developed by Corollary, Inc. which includes a SCO XENIX 
2.3.2 GT based kernel.  The Z-1000 configurations are 2 to 6 CPUs (each with
64KB of local cache), up to 64 MB of EDAC (Error Detecting And Correcting)
memory, an integral UPS power supply, SCSI (Adaptec 1542) host adapter,
1 to 4 SCSI (150, 300, and 600MB) disks in the main drive bay, a 150MB Archive
tape drive, floppy disk, and up to 160 tty devices...  Additional SCSI devices
are supported by a second Adaptec host adapter, "mkdev hd/tape" can configure
9 disks, 2 cartridge tapes, and 2 reel-to-reel tapes as shipped.  The Z-1000
supports additional ISA bus cards with standard SCO XENIX device drivers.
Standard SCO software packages are used on the system, including SCO XENIX
TCP/IP, XenixNet, Development System, Text Processing, and Office Portfolio.

whew... sounds like an add...
The SCO XENIX OS for the Z-1000 is not listed in SCO price sheets because
it is a specific version for the Z-1000 and it is bundled with the
Z-1000 hardware -- if you can use it you already have it.

SCO announced its MPX extension to SCO UNIX System V/386 -- this product
uses Corollary Inc. technology -- I believe announced availability is in
1st quarter 1990...

That's a little rough...  SCO has their own system software group that
started with standard AT&T UNIX System V.3.2 -- when/if you get into it
I think you'll find that it differs from the AT&T release about as much as
ISC does, only in different places.  BUT it does run all the same binary
apps that AT&T and ISC run (given appropriate system/package support).
