[Version 2.10 Beta Build 4 from 2009-26-04 18:00 GMT]
Made with Phun 5.28
It is done! The second version of the phun computer is ready for your input!
The computer is part of the Phun Computer Project

Features:

Tutorial / How to use:


General important input details:
-Don't type too fast! Wait until your input appears on the screen
-Don't hold any key! Touch the keys and release them quickly!
-Press and hold Alt if you accidentally have held a key for a long time. This will repair the virtual keyboard 85% of the time.
-Don't press Ctrl+Z to undo your input! Use the undo button << to undo your input (otherwise phun will crash)!
Supported input keys:
-Keypad, ENTER (not on keypad), A-Z, 0-1, SHIFT, +, -, .

-Use Ctrl-Left to make a SPACE

I used the QWERTZ keyboard.
