    A known issue, affecting the functioning of the mouse port, was addressed by changing the order in which themicrocontroller handles certain interrupt requests.

To update themicrocontroller firmware:
- Download the firmware object file to the server's c:\tmpdirectory
- Stop the 'server applet'
- Switch off the ZX Spectrum
- Connect a joystick to the interface's port
- Connect the interface to a USB port of the server
- Hold the joystick to the RIGHT while switching on the ZX Spectrum. No LED will light up.
- Release the joystick
- Start the 'server applet' on the server machine. The leftmost (U) LED willlight up and the (C) LED will blink shortly for each 1 KB block transferred.The process takes less than one second.
- Switch off the ZX Spectrum.
