They've had heated discussion about Coherent recently and surely someone would be able to tell you more about it than I could. A lot of people on that group were upset that the Coherent cc wouldn't handle all of the PC memory models, as well as the fact that Coherent sells -- WITHOUT source -- something similar to UNIX v7, while Minix offers source and a v7 clone for about $10 less. I believe you can get Minix free from some FTP sites, tho' I don't know about the legality of it.

Does anyone have information >that would be of help to me? I bought, tried, and returned Coherent. Problems were: - Wouldn't run with my ESDI disk controller (won't work with SCSI controllers, either). - Not compatible with my AMI BIOS (though this may be fixed now.) - Limited to SMALL programming model!!! I found the last problem the most unacceptable. I was interested in learning more about Unix, but you can't even get a decent editor to compile in that environment! I definately don't recommend it. Don't just take my word for it, ask the same question in comp.os.minix and see what happens! -- ---------------------------------------------------------------------------- Mark Medici/SysProg3 * Rutgers University/CCIS * medici@elbereth.rutgers.edu ----------------------------------------------------------------------------

The release of Coherent that is being advertised lately is restricted to AT-class machines or "better." That means 80286 or 80368*, and precludes XTs. It also requires an MFM or RLL controller. The C compiler in this release generates code only for small model, a limitation that sours many on the product. That said, it sure is alot of product for the price, albeit not bug free. There is a mailing list for people interested in or using this version of Coherent- write to "coherent-request@cs.wisc.edu" to subscribe. Back traffic is available upon request; the answers to some of your burning questions (along with plenty of drivel, of course) may be lurking in there somewhere. There are also a few archive sites with a small but growing collection of public domain software that has been successfully ported to Coherent. -- Scott Rose rose@cs.wisc.edu

I have a friend who tried Coherent, and was also quite displeased about
being limited to the small memory model. He has spoken to a couple of
people, and one person recommended that he look at ESSEX (sp?), Everex's
version of Unix. Apparently, this operating system costs about
$500-600, but is as good as SCO Unix, which costs MUCH more. Also,
ESSEX apparently includes X windows, and other goodies (maybe NFS, I
don't know). As you can tell, I haven't personally seen any information
about this, but if I were looking at gettin Unix, I would definitely
look into ESSEX, rather than Coherent. Like they say, you get what you
pay for.

Esix is a SYSVR3 UNIX, unlike Coherent which is really just a SYS7 Unix CLONE. -- Bill Heiser Work: heiser@tdw201.ed.ray.com {decuac,necntc,uunet}!rayssd!tdw201!heiser Home: Bill.Heiser@f240.n322.z1.fidonet.org (Fidonet 1:322/240) The Think_Tank BBS (508)655-3848 1200/2400/9600-HST Other: 75106.2332@compuserve.com Other: heiser@world.std.com (Public Access Unix)

(Anyone who recieved that last posting before I canceled it, sorry!) I'm not sure where this should be posted, but for lack of a better place I'm posting here. Does anyone have/use/have used Coherent on the PC? I'm interested in getting a small Unix type kernel up on my PC, and I'm not sure which one to go with. If Coherent is not a good thing to go with, could anyone make a suggestion on what would be. (I'm on a budget, please be gentle) What version of UNIX is Coherent close to?

Does anyone have any experience with Coherent, a $99 dollar UNIX look-a-like for PC's that allows MSDOS to run as well? Please respond via email directly. Thank you.
