I've attached a C program which determines the model and the amount of
memory installed in C code (by querying the ODM directly). It can be
compiled using
  cc -o model model.c -lcfg -lodm

#include <stdio.h>
#include <sys/utsname.h>
#include <unistd.h>

#include <string.h>
#include <cf.h>
#include <sys/cfgodm.h>
#include <sys/cfgdb.h>

void main (void)
{
  struct utsname	name;
  int			memsize;

  char         s[3];
  int          model;

  struct CuAt *odm_obj;
  int          how_many;

  uname(&name);

  printf( "sysname  = %s\n", name.sysname );
  printf( "nodename = %s\n", name.nodename );
  printf( "release  = %s\n", name.release );
  printf( "version  = %s\n", name.version );
  printf( "machine  = %s\n", name.machine );

  printf( "model    = " );
   /* On AIX, the model is encoded in the last 2 non-zero digits
      of the model code (uname -m)
   */
   s[0] = name.machine[ strlen( name.machine ) - 4 ];
   s[1] = name.machine[ strlen( name.machine ) - 3 ];
   s[2] = '\0';
   model = strtol(s, NULL, 16);
  
   switch (model)
   {
