/**
|

|
|
* The HACK computer, including CPU, ROM and RAM.
|
||
|
|
* When RST is 1, the program stored in the computer's ROM executes.
|
||
|
|
* When RST is 0, the execution of the program restarts.
|
||
|
|
* Thus, to start a program's execution, reset must be pushed "down" (0)
|
||
|
|
* and "up" (1). From this point onward the user is at the mercy of
|
||
|
|
* the software. In particular, depending on the program's code, the
|
||
|
|
* LED may show some output and the user may be able to interact
|
||
|
|
* with the computer via the BUT.
