23-May-2013     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. |
