Imp-Export Mode


This mode's primary role is to allow users to download files onto a standard OZ v2.2 or v3.0 Z88 so that a copy of the Eazylink popdown can be written to a Flash card or EPROM card on the Z88.


Although it is possible, it is not recommended to use this method to download OZ 4.5 due to its size and lack of file checking facilities.

You should skip this section if you already have a copy of OZ4.x or Z88 Eazylink. Please go to Starting Eazylink on the Z88.

  • Connect Z88 to the Desktop.
  • On the Desktop, start Eazylink2


  • It only allows saving and receiving files from the Z88's root Directory.
  • Drag and Drop is not supported.
  • Eazylink Popdown Protocol Testing is not supported


Downloading Files

Download from the Internet the files needed to transfer to the Z88 and save them all in a directory.

On the Desktop start Eazylink2.

First time use

The first time Eazylink is connected to the Z88 the Com Port window is displayed.

The Com Port details will be displayed.

ImpExp communications preferences

  • Clear the 'Open Serial Port on Startup' tick box
    Select the 'Default Serial Port:' to the device name the Z88 is connected to.
    Click the 'Refresh' box and click OK.

An intelligent guess is made at which Serial Port is being used. Here is your chance to check that the correct one has been selected. In this case Windows is using COM 5.

Getting control of Eazylink can be difficult to do initially because Eazylink2 is expecting the pop-down to be running on the Z88. Just keep waiting until  you receive the Reading Z88 Devices Command Failed Command Error window.


Choose 'Ignore.'

What you really need to see is the top Eazylink Menu not being greyed out.

Select the Directory to be used

Here is a picture of the blank screen you should see. The left-hand window (normally used to show the Z88 side) is not used in this Imp-Export Mode. The right-hand side window showing the Desktop side is used. Select which Directory is to be used here. The selection of the files are made in a different window later.
