I have been talking with the company doing the Unix port for Definicon,
and they assure me it is System V r2.  I have some literature about it
(I know... what does that prove?...:-), and it looks real nice.  It is
based on National Semi's validated port called System V/Series 3200.
I also have the manuals for the Unix, sanz a few update pages for the
DSI-32.  These are AT&T manuals with updates for the 32k and DSI-32.

As far as new chips go, you will need *specific revisions* of the
CPU and MMU.  These, for all practical purposes, will be available
only through Definicon as an upgrade package.  This because the
chips needed are still in limited production.  I tried to get them
through the NS & TI Distributers with no success.  No word yet as
to whether there will be a cost for the upgrade.

This all depends on what your idea of fine is. 
If you just want to run one thing real fast (*not* a bad idea!) the MSDOS
shell *is* just fine.   However, if you have a need for concurrent tasks,
its another story.  The people at Definicon swear by DRIs Concurrent CPM/
DOS.  However, my experience has shown several fatal (for me)flaws in CCPM.  The
main one is that CCPM does not work with the Cartridge Drives I have
installed in my system.  DRI ackowledges this, but has no fix or explanation,
though one of their techs said something about buffers not being flushed.

I agree, lets here some more from DSI-32 owners!  Anybody got some nifty
code they want to share?  How about ideas for *using* all this power, now
that we've got it?  Even queries on how to do things...   Lets hear from you!
