Changing keyboard behavior on the MEGA65 computer #Keyboards #VintageComputing @dan_sanderson
On Commodore computers that have a Home key, many people routinely hit Home when they mean to hit the Del key. The only way to move the cursor back is with the arrow keys. With the MEGA65, Dan Sanderson finally had the opportunity to do something about this.
I need a backspace key frequently on Commodore computers because I type faster than these old machines can handle. Specifically, they lack a modern keyboard feature called “n-key rollover” (NKRO) that helps the computer figure out what you mean to type when you’re typing so fast that you’ve hit the next key before letting go of the previous one. Despite its newness, the MEGA65 inherits this historical gap from its predecessors.
See how some clever assembly code allows for saving and restoring the cursor state in the post here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
