Anyone out there know about Coherent Unix (whose advertisement is frequently seen in Byte magazine)? What exactly is the product? A unix operating system or just a collection of unix utilities for DOS? Also, which magazine can I find reviews on it?

A summary of all the comments on the Coherent package I've ever seen posted (since the very first article asking for comments) is available for anonymous ftp from math.princeton.edu:pub/rjc/csip/coherent.Z. Users who cannot ftp may obtain a copy by sending the one-line mail message send coherent to rjc@math.princeton.edu. Details can be found in the Frequently Asked Questions file.

The biggest catch is supposed to be the fact that the C compiler only works in small memory model.

Doesn't comply with SVID (System V Interface Definitions) or POSIX. Also, CCCP (Coherent-to-Coherent CoPy) is broken. Byte did a review of Coherent. Turned out to be a much bigger lemon than I had even envisioned. What was surprising is that the Byte Labs Unix benchmark did compile under Coherent, but would not run. Now that was worth a good laugh or two after I read that in their review on it. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | Small memory model only for ** ARPANET : crash!pnet01!jca@nosc.mil | Unix?

Coherent was reviewed in a recent Byte (a real review, not the commentary from a previous issue). Turns out it's similar to MKS Toolkit, and not very effective. Read the article.

The MKS Toolkit is a set of programs that work with dos, providing a Unix-like interface; Coherent is a standalone implementation of a Unix-like kernel and utilities. For me, Coherent 3.10 is deja vu. It appears to exactly duplicate the Version 7 Unix on a PDP-11 that I used in 1980 (except no source), with a few enhancements like clones of emacs and vi. Coherent has the same 64KB text + 64KB data limitation; it has on-line manual pages, cc, yacc, uucp, nroff (plus troff with HP LJ output). I marvel at how faithful the implementation seems. Coherent is a clone of Unix as it was 10 years ago. You'll have to decide if it fits your needs. -Dale

Coherent is in the class of Minix which is a V7 clone.

Coherent is an entire multitasking operating system, with versions of many of the same utilities that come with MKS Toolkit and with Unix. This is not very profound similarity, really. -- Scott Rose rose@cs.wisc.edu

Coherent does not have vi; it was felt by Mark Williams Co. that, given a decent implementation of a decent editor like MicroEmacs, a bear like vi was not necessary (I bet the code licensing had something to do with it too). I for one will not disagree with their decision. --jp

I don't know if PC Magazine did a review on Coherent yet but Byte did.. SCSI disks are supported under Coherent release 3.1.0. I think only Adaptec AHA-154x series host adapters are supported under new release. -- ------------------------------------------------------------ Mohd H.

Actually that may have been V6... a multitasking o/s with compiler for $99 is not all that much of a lemon, even if it isn't UNIX. That just means that it won't be the right solution for all problems. Wendin had unix and VMS clones out some years ago, which would run three users on an XT, with some happiness. They were subsets, too, but useful if your problem fit their solution. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me

That's probably quite correct, given that MWC ads also state that it won't
work with SCSI disks.

Just to clarify this, MWC has released a new version of Coherent (3.1.0) which support Adaptec SCSI adapter. May be you should call them first before make any statements. And PC MAG never reviewed Coherent. -- Mohd H. Misnan */* UUCP: mhm!hamid@uop.uop.edu University of The Pacific, */* Inet: acs17111@uop.uop.edu Stockton, CA 95211 */* hmisnan@madvax.uop.edu

And PC MAG never reviewed Coherent. It would be easy to check that there was in fact a recent review (first look) in PC mag, Issue 19, Nov 14, 1990. Also, never is a long time. I believe the first time coherent was in the mag was about 1984 when there were reviews of xenix, qnx, coherent, and other "unix" systems. Yes, we're talking versions for the then current XT with 10mb disks on board. Kaare Christian
