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...

Or > is this a flavor of the ISC System V.3.2 UNIX one? 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). --____ ___ ____ /| ) /) / ' /| ) Paul E.
