(I'm not sure Robot Odyssey will even run under Level II...)

The only one of those that will actually use up all 512K is Multivue,
and even that only if you get lots of stuff going at once.  Plus,
gshell's little more than a toy, you'll eventually need real shell
windows anyway.

As far as which /term to use, 2 boot disks were always suffiencent for
me: an all windint boot, and a vdgint+windint boot.

I'm not sure why you want to autostart specific apps like this?
Wouldn't it be more generally useful to just start out with a shell?
Whichever /term you booted?

autoex is a binary module that will be run after startup but before
sysgo spawns a final shell and exits.

Here's my startup, maybe it will provide hints:

*  shell+ commands used here
* Echo welcome message
echo * Welcome to NitrOS-9 Level 2 *
echo *   on the Color Computer 3   *
* Lock shell and std utils into memory
link shell
load utilpak1
* set bit banger to 2400
xmode /p bau=4
* Start system time from keyboard
*setime </1
*Start system time from smartwatch
setsystim
date -t
lookterm2 $012B5D
*touch /dd/tmp/term_win if /term is 80 col
var.1=foo
if -F /dd/tmp/term_win
then
    var.1=windint
    control -e
    iniz /w1
    iniz /w2
    display 1b 20 02 00 00 50 18 0a 03 03 > /w1
    display 1b 20 02 00 00 50 18 0a 03 03 > /w2
    shell i=/w1 &
    shell i=/w2 &
    cd /dd/sys
    merge stdfonts
    merge stdpats_2.plus stdpats_4.plus stdpats_16.plus
    merge stdptrs
else
    setype rh
*    shell i=/v1 &
*    shell i=/v2 &
fi

On a term80 boot disk, this automatically sets up for multivue
("control -e", merging the fonts, pats, and ptrs), but leaves me with
shells running on /term, /w1, and w2.  To actually start multivue, all
I have to do is run gshell.

On a term_vdg boot, it still sets the monitor type and mouse pointer
type, and again, drops to a shell, ready to run carmen, dm3, koronis,
whatever.

Oh yeah, and to use that you'll need lookterm2.  Here's the source:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <modes.h>
#define MARK "/dd/tmp/term_win"

main(argc,argv)
    char *argv[];
{
  int pipe,sin,sout,status,marker;
  char line[80];
  if((pipe=open("/pipe",3))>0)
  {
     sin=dup(0);
     sout=dup(1);
     close(0);
     dup(pipe);
     close(1);
     dup(pipe);
     os9fork("ident",8,"-m term\n",1,1,0);
     close(0);
     dup(sin);
     close(1);
     dup(sout);
     while(readln(pipe,line,80)>0)
     {
#ifdef DEBUG
       if(argc>1)
           writeln(1,line,80);
#endif
       if(strncmp(line,"Module CRC:",11)==0)
         {
          if(strncmp(&(line[13]),argv[1],7)==0)
            {
               marker=creat(MARK,S_IWRITE);  /*unlike the raw asm */
               close(marker);                /*sys call, C creat dont */
            }                                /*bomb out if file exists */
          else
            {
               if(access(MARK,S_IREAD)==0) /*file does exist*/
                 {
                    unlink(MARK); /*delete it*/
                 }
            }
         }
          
     }
     wait(&status);
  }
  else
  {
    writeln(2,"Couldn't open pipe",80);
    exit(216);
  }
  return 0;
}

Umm, ick.  I should really clean that up before I blast it over the
entire net.  Oh well.
