Abajo mostramos un listado completo del código fuente para obtener datos del PC: tipo de procesador, número de procesadores, arquitectura, tamaño de página, memoria virtual, dirección de memoria baja y alta, ... Para ello necesitaremos un formulario, un ListBox y un botón:

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;

type
  TForm1 = class(TForm)
    ListBox1: TListBox;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var 
  SysInfo: TSystemInfo; 
begin 
  GetSystemInfo(SysInfo); 
  with ListBox1.Items, SysInfo do 
  begin
    Add('ProcessorArchitecture:' + IntToStr(wProcessorArchitecture)); 
    Add(FloatToStr(dwPageSize) + ' Kb page size'); 
    Add(Format('Lowest memory address accessible to applications and DLL - %p', 
      [lpMinimumApplicationAddress])); 
    Add(Format('Highest memory address accessible to applications and DLL - %p', 
      [lpMaximumApplicationAddress])); 
    Add('OEMID:' + IntToStr(dwOemId)); 
    Add('ActiveProcessorMask:' + IntToStr(dwActiveProcessorMask)); 
    Add(IntToStr(dwNumberOfProcessors) + ' - number of processors'); 
    Add('ProcessorType:' + IntToStr(dwProcessorType)); 
    case wProcessorLevel of 
      3: Add('Intel 80386 processor level'); 
      4: Add('Intel 80486 processor level'); 
      5: Add('Intel Pentium processor level'); 
    end;
    Add(FloatToStr(dwAllocationGranularity / 1024) +
      ' Kb - granularity with which virtual memory is allocated'); 
    Add('ProcessorRevision:' + IntToStr(wProcessorRevision)); 
  end;  
end;

end.
