In a recent Dr. Dobb's Journal I came across an ad for a product called Coherent which claims to be a virtual clone of UNIX, and a *very* inexpensive one. Before I rush to place an order for the thing, I want to call upon the wisdom of the net to get some feedback from those of you who have used Coherent. Any input, positive or negative, will be greatly appreciated. --------- Rafael Cruz rcruz@paul.rutgers.edu

If you want to do programming in a Unix environemtn, it's probably OK. If you want to port much of anything from Usenet, then forget it. -- Bill Heiser | heiser@sud509.ed.ray.com _____________| heiser@world.std.com | bill.heiser@f322.n240.z1.fidonet.org (Think_Tank BBS 508-655-3848) | 75106.2332@compuserv.com

The answer is...not very. Here's the bull on MWC's Coherent. 1. Swapping is not currently supported. 2. It's only a small model 286 Unix (probably ala V7). 3. A lot of BSD/SysV code will NOT port over easily. It's basically a commercial 16-bit Minix. That's it. You have the 64K code and data segment limitation which makes a lot of code impossible to port. MWC claims (at least from some posts on the net) that there will be a 386 version that supports demand paging, but I doubt it will be for the same price. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | Small memory model only for ** ARPANET : crash!pnet01!jca@nosc.mil | Unix?
