Resetting the shared keyboard and mouse
The LINDY CPU Switch Junior is fitted with a keyboard and mouse reset function. This function
powers down the devices for a couple of seconds and resets them. The rest of the LINDY CPU
Switch Junior continues to work normally and the connections to the CPUs are unaffected. This
function is useful if the mouse has become disconnected or is to be changed for another type. It is
also useful if there is an error that has caused the keyboard or mouse to operate incorrectly.
To reset the shared keyboard and mouse, enter maintenance mode (see section 4.2). Whilst within
maintenance mode press the front panel key. The power light will go off for a few seconds and
then come on again when the keyboard and mouse have been reset. The LINDY CPU Switch
Junior will then be operating normally.

Resetting the LINDY CPU Switch Junior
The LINDY CPU Switch Junior is fitted with a hardware reset function that does not require the
power to be disconnected. The reset function is accessed using option switch 5 (see section 4.1).
This option switch is connected to the microprocessor within the LINDY CPU Switch Junior. When
switch 5 is in the ON position the LINDY CPU Switch Junior's processor will halt all operations.
To perform a complete reset of the LINDY CPU Switch Junior, move switch 5 from the OFF
position to the ON position and then back to the OFF position. This action is equivalent to
disconnecting all the power from the LINDY CPU Switch Junior and then powering it on again as it
performs a complete microprocessor hardware reset.

Querying the LINDY CPU Switch Junior's firmware version
For technical support purposes it is sometimes useful to know the firmware version of the LINDY
CPU Switch Junior. The LINDY CPU Switch Junior can report its firmware version using a
maintenance mode function.
To find the firmware version of your LINDY CPU Switch Junior, switch to a CPU that is showing
the DOS prompt or is running a text editor or word processor package. It doesn't matter what
package this is provided that the characters typed in at the keyboard are displayed on the screen.
Enter maintenance mode and type
version number will be reported on the CPU screen as three numbers. For example, if the LINDY
CPU Switch Junior reports 118 then the firmware version is 1.18.
