|Location||Super Gold Card|
This command is the complementary command to SCR2DIS - it enables the QL’s second screen and is also memorised by the Super Gold Card so that the second screen will always be available for use by programs.
In order to make proper use of the second screen, you will still need to startup Minerva in dual screen mode and use the appropriate MODE commands. Non-Minerva QLs can still use the second screen by using various machine code techniques.
See SCR2DIS for more information.
