How to monitor Oly E-series camera firmware/info/statistics?

I asked Andrzej Wrotniak at www.wrotniak.net how to read out camerahouse stats, and he says this:

How to display the info pages of your Olympus 4/3rds camera

Open the CF card door. (This can be done with the camera on.) If the camera is off, turn it on with the On/Off switch. The "Card-Cover Open" message will appear on the camera's LCD monitor.

Simultaneously press the following two buttons:

- E-1, E-300, E-500: Press the [>] (play) and "OK" buttons.
- E-330: Simultaneously press the "Menu" and "OK" buttons.

On the E-1, the firmware version of the camera and attached lens and flash will be displayed on the camera's LCD monitor. If you're using an E-300, E-500 or E-330, the camera model name will be displayed.

Press: Up, Down, Left, Right, Shutter.

Use the navigation buttons to display the desired info page:

- Up – display Page 1
- Right – display Page 2
- Down – display Page 3
- Left – diagnostic display

To return to normal camera operation shut the CF card door.

Here is what each info page contains:

E-1 Page 1 (up)

Note the line
"Press: Up, Down, Left, Right, Shutter."
Skipping this step will prevent page navigation!

Useful i.e. when buying used, for checking total number of exposures etc.
