Application 5150

I've already built a 64 byte RAM, a 4x4 bits multiplier, a 6 bit adder. My 64 byte RAM used D-Flipflops and was controlled by pressing some buttons and changing some levers. If both the output of the Flipflop and the global read command for the actual byte were high, the output went onto the (binary) "torch" display. For example, if I wanted to display the number 10001011, the left torch, the 2 torches on the right and one torch in the middle was turned on. A long time ago i've built a kind of cinema with 16 Pixels (2x2 blocks moved with pistons) which played a film with a length of about 100 Redstone ticks (saving of the film included). At first, the film was saved in Repeaters which were in a circuit (a kind of clock). Each repeater had a delay of 4 ticks, and so the film was turned on all the time. Later I changed the circuits saving the film into AND-Gates. One input was a kind of "clock", the second input easily was a lever. If you pressed the button to play the film, a redstone signal went on to the first AND-Gate, was delayed 4 ticks after it, went to the next AND-Gate, was delayed 4 ticks after it, and so on. That time I used CraftBook's Transmitter and Receiver IC's in order not to need much redstone.
