LINDY CPU Switch Dual Multi-Platform Installation and Use Page 40
4.4 COMPUTER display and key switch
The COMPUTER key selects the computer port that is to be connected to the user
port that is currently displayed on the green USER display (see figure 1). Pressing
the key will cause the red COMPUTER display to change to the next available
computer port in numerical sequence. The next available computer port is defined by
the way that the LINDY CPU Switch Dual MP is configured.
There are two special computer ports that may be selected using the COMPUTER
key switch. These are the on-screen menu port 'o' and the non-existent channel zero
'0'. Selecting the on-screen menu port will cause the on-screen menu or the login
menu to be displayed. Selecting channel zero will cause the video to be disabled and
all keyboard and mouse activity to have no effect upon any of the connected
computers. These channels are provided as convenient places to 'park' user ports
that are not currently in operation.
