I’m planing on making an emulator of a handheld electronic game toy called Split Second from Parker Brothers. It used an LED screen that consisted of lines and dots to play 5 different games that have to be completed as fast as possible. The time in seconds is your score. I got it as a kid in the 80s and still have it because I loved it. Look it up.
At the moment the emulator only consists of the graphic engine that draws the LEDs of the screen.
The screen matrix is 7 x 11 and shows horizontal or vertical lines or dots, depending on the position referenced. To use it set x and y and gosub LEDON or LEDOFF. The positions between the horizontal lines do not light an LED.
If someone wants to use the engine for their own games, feel free to!
