There is no public domain Unix anywhere.

There are various Unix `lookalikes' (with varying degrees of `alikeness')
that can be obtained for free or inexpensively; as far as I know, *none*
of those are public domain.

`Public domain' has a specific meaning above and beyond `may be given
away freely'.  For instance, GNU software is not public domain.

Coherent, which advertises in the popular Unix magazines...about $99.

Minix from Prenctice Hall (around $130).

I'm running Coherent here.  And Cnews, rn, and smail 2.5.  This is 286
protected mode Coherent.  386 VM Coherent will probably ship by the end
of the year.


 
 
 

1. My Unix 386 machine Is Faster Than My 486!!

I recently set up an AT&T StarServer S (486 machine) with 20 MB of RAM,
running Unix V Rel 4.0 version 2.1 and Informix 4.10.  I copied over a
database application from a 386 machine with 8 MB of RAM, running Unix 3.2.3,
recompiled and ran it.  The 486 is considerably SLOWER than the 386!!!

One thing that I know I must do is to tune the parameters (idtune,mtune).
Looking through the manuals they do not really give you a recommendation
on what to tune with 20 MB of RAM to make the system run instead of crawl.

If anyone has any information on tuneable parameters for REL 4.0 or why the
486 is slower than my 386, I would greatly appreciate it!
