Dumping The Rom

Dumping a ROM from a Newton device you own.

Two methods are available: via a serial line or via TCP/IP (i.e. via an Ethernet access).

Hammer/Newtsbug (serial line)

Using a low-level debugger such as Hammer or Newtsbug, you can make a dump of the memory. This is slow and works over the serial line.


  • A computer running a Mac OS version less than OS X, or the Classic environment
  • Hammer or Newtsbug (they can be found on UNNA,
  • A serial connection between your Newton and the Mac: – a built-in serial port for computers booting in Mac OS versions less than OS X – or a USB to Serial port adapter compatible with Classic.


  • Install Debugger Connection or Newtsbug Connection package on your Newton.
  • Plug the Newton with the Mac using the serial line.
  • Run Hammer or Newtsbug on the Mac.

A standard open file dialog appears: choose the debugging image corresponding to your Newton (Senior CirrusNoDebug image, Senior DCirrusNoDebug image or Newt KNoDebug image for the MP2x00 US, MP2100 or eMate 300 respectively). 

  • Tap the Debugger Connection or Newtsbug Connection package on your Newton and choose connect.
  • On the Mac, once the connection is established, choose Save Memory from the File menu.
  • Save memory between 0 and 00800000 (8 MB).
  • Wait.

ROM Dumper (TCP/IP)

ROM Dumper is a faster approach but requires an internet connection between your Mac (or any Unix computer) and your Newton.


  • A working TCP/IP or Internet connection between your Newton and your Mac.


  • Install provided ROM Dumper package on your Newton.
  • Tap the ROM Dumper icon in the Extras Drawer.
  • Tap start.
  • If your Newton isn’t connected to the Internet yet, choose a connection method. It’s also the time to insert your Ethernet/WiFi card.
  • Note the IP of the Newton (ROM Dumper mentions it).

ROM Dumper listening

  • Launch Einstein Platform (the GUI version).
  • Choose Dump ROM from the Einstein menu.

Dump ROM Menu Item

  • Type the IP address of your Newton.

Dump ROM Panel

  • Click start.
  • Specify where to save the Newton ROM. Be careful not to erase previously dumped ROM file if you are dumping the ROM of several different Newton models.
  • Wait (a little bit).

The platform will be configured to use the newly dumped ROM.

Alternatively, you can use nc(1) command line tool.

You can’t perform that action at this time.
