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?
