Why only 16K of RAM ?

iSol
Hello,

why we've build only 16K of RAM instead of the max addressable 64K ?

Thanks,
Ion

The Hack instruction set makes it difficult to use RAM addresses above 32767 (15 bits).
RAM addresses 16384 and above are used for the Screen and Keyboad I/O devices.

You will learn about the instruction set and I/O map in the next chapter.
