|
|
|
|
ROMDIR=. ./napple1

|
|

How to use programs on napple1
|
|
==============================
|
|
|
|
- Key map
|
|
|
|
In normal terminals, if you press 'D' key, it will be echoed as 'd' on screen.
|
|
And press 'Shift + D' prints 'D' on screen. Shift key works to flip caps.
|
|
|
|
However, napple1, if you press 'D' key, it will be echoed 'D'. All letters
|
|
you can type is upper case only. Because original apple1 has a limit to do so.
|
|
And shift key works like a control key in napple1.
