Building screen and keyboard RAM

[tyler1313]

I'm trying to build the hack computer on a program called logisim. I'm curious about how to build some of the built in chips in this course as there is no explanation of how there are built here. If I was going to build say the screen and keyboard RAM, how big (how many registers) would they each be and would I build them exactly the same as the RAM16k chip? In this case, the only difference between the RAM 16K and the screen/keyboard RAM is that the value of the screen registers affects the pixels on screen and the value of the keyboard registers is affected by keyboard input?

The main problem with Screen and Keyboard with Logisim are that you can't connect what you build with your PC's screen or keyboard.

IvanT build a custom component for Logisim that is the nt2 Screen and you can use Logisim's built-in Keyboard component.
