Hello. This is my project. It was started in February 2013 and I have kept updating and making it better since then. The computer is currently on version 2.7, I have made various changes ever since version 1.0.

More info:

Command blocks are used in the computer, however ALL the logic happening is made up by redstone components. I am not using any setblock or anything of those. Command blocks are only used for the keyboard/mouse/music/some wireless redstone where that's needed and for the chat messages.

Current specs and features:
28 displays (36 if you count icons and mouse display) Capable of displaying A-Z 1-9 and alot more.
4 bit Multiplication, 8 bit addition and 4 bit subtraction, square
4 commands
Music Hub currently containing three songs
Fully Functional Trivia Game with 5 questions.
Wireless Keyboard and Mouse
Icons to launch/enable/disable etc. programs.
378 Bytes of memory, however due to the lack of 378 displays (hehe) only 14 bytes can currently be used at the same time.
A full working Tic Tac Toe game with it's own AI
My own OS: lpgOS

The computers programs are launched with the mouse on the icons.
I currently have 4 open spaces for 4 more icons, meaning 4 new programs/games/anything. If you wanna suggest anything feel completely free to do so, I suggest doing that on the forum page linked down below or through a private message to me on youtube (Lespaulguitar10).
