In the xenix-group there are some more or less hot debates to SCO in
general and SCO UNIX 5.3 in special. I'll have to decide:

	Should I buy 386/ix or SCO UNIX 5.3  ?

My question to all of you who have experience with the SCO UNIX and/or
ISC 386/ix:
1. Does SCO UNIX have so many bugs as noted here ?
2. Is there an online manual in SCO UNIX 5.3 ?
3. How is the support from SCO ?
4. How do SCO UNIX and ISC 386/ix compare (documentation, support, bugs,
   device drivers, performance especially to disk IO) ?
5. What about software: X11, TCP/IP, VP/IX for *SCO UNIX* ?

Thanks for any reply.

Note: please email, I'll summarize.

It is at least there, and they seem to come up with workarounds for problems
that cannot be fixed quickly.  All of the important updates are available
from their dial-up uucp site. My experience with other companies has been
much worse.

It's hard to compare disk access speed at this point - at least SCO UNIX
will be (hopefully) changing in terms of its SCSI support.  SCO and several
other companies have been working on speeding up SCSI support for both
XENIX and UNIX, and these changes will eventually wind up in both (I assume).

One product that SCO has that makes them hard to ignore is the product that
supports multiple CPU's in a single machine, such as the Compaq Systempro.

What product is this? I haven't seen anything in my SCO price lists or
other info that says they have a multiple CPU product. I remember seeing
a press release that said they were working on a multiprocessor
implementation along with a couple of other companies.

Do you know something I don't?

  It was demonstrated at UNIX Expo, among other places. WIll handle 386
or 486, although I'm told that the 1st CPU must be 386. This was
developed for the Zenith (I believe it's called the model Z1000)
multi-processor machine. Now that ZDS has been sold I don't know the
status of the project.

  The version I saw at Expo looked really good. Like any multi-cpu
system it becomes outstanding with pipes. I didn't see any info on a
multi-make, although that's one of the best reasons to have the extra
CPUs. I'm not sure thay don't have it, just that I didn't see it.

Right now i think they only have 2 processor Machines, but they were talking
about having 16 processor 386's (and 486's).  

All I can say is this kinda stuff makes me drool :-)

Any information whose UNIX kernel SCO is licensing this time around?  Or
is this a flavor of the ISC System V.3.2 UNIX one?

  The kernel seems to be Xenix 386. I believe that the company who did
the port is called CONSENSYS, but I don't have the info right here. The
port was done for the Zenith Z-1000 multiprocessor system.

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).

The product in question is called SCO Unix/MPX.  It should be available early
1990, perhaps Feb or Mar.

The company that wrote the extensions to Xenix is named Corollary.  They have
been building their own boards based on 286 processors and using the kernel
extensions for several years now.  Yes, SCO is licensing the technology from
Corollary.

Zenith has been selling a 386 multi-processor system for a year now.

Compaq has announced a new computer called the SystemPro which contains two
processors and will use this new Unix version to "acheive truly symmetric
multi-prossing" according to Compaq and SCO.  As a disclaimer, I must say that
I am by no means an expert on what is or is not symmetric, so perhaps someone
else might clear this matter up.

Several other computer mfgs are also releasing multi-processor systems which
are built around the 386 and 486 chips.

Bill, normally you are right on the money, but this time a little correction
is in order.

SCO MPX is the multiprocessor extension for SCO Unix System V/386 rel 3.2
and Open Desktop. SCO partnered with Corollary in Irvine, CA to implement
this. First done for the Z1000, it also runs on the Compaq Systempro,
Mitac 500, apricot MC486 and Corollary 386/smp and 486/smp. Other
vendors to come.

I don't want this to turn into an ad, if the consensus of the net is that
more detail are desired, I can post them. Anyone who wants can get our
technical background paper from their local SCO Authorized Reseller or
by emailing a request to sco!info.

Quoting the Nov/Dec 1989 DiSCOver (SCO Newsletter) article on SCO MPX:
"SCO MPX is based on multiprocessing software technology developed by
Corollary, Inc.  Through a joint development agreement with SCO, this
technology has been adapted to become the standard multiprocessing
extension for SCO Operating Systems."

MPX will be installed by invoking the "Add a Supported Product" function
in custom(ADM) after you have installed SCO UNIX System V/386.  MPX is
not XENIX based; the Corollary technology has been re-implemented as an
extension of SCO's standard UNIX 3.2 product.

SCO started with the AT&T UNIX System V/386 flavor to which it added C2
security and POSIX FIPS compliance (among other features).

The Zenith Z-1000 is shipping with a XENIX 2.3.2 GT based operating
system developed by Corollary, SCO, and Zenith Data Systems.  When
SCO MPX becomes available it will support "... OEM designs based on the
Corollary's 386/smp and 486/smp machines [and] ... the Zenith Z1000."
as per the Nov/Dec 1989 DiSCOver article.
