I like the idea, I'm in and I have an idea how it can work for the user. We start with a code of four or six numbers. When we have unlocked the computer there will appear two pictures. One picture is "on" in 1.30 seconds(using SR latch were reset input is powered after 1.30s. When that is reset the other activates) When that is done you will come to the menu - where it is three possibilities to choose between: Apps, Clock and user help. To choose the one you want, you use the touchpad that th3 3l3ctroman made. And then to when you click in to one of the programs:
Apps: As you said longer up th3 3l3ctroman, we could have music, video editing, word and games. I agree that we need that stuff but we still need more like calculator and a helping program for binary counting, many people dont understand that.
clock: When you chooses clock from the menu, I think there should appear a digital clock on the screen that is possible to set and always goes. I'm not sure but maybe there should be a stopwatch there too, but it is not the most important part.
User help: You will come to a full page of text. (I think there should be space for up to 24 letters per page). If we uses a keyboard with a "next" and "previous" button we can just use them. We have to make an 8-bit counter to make this work because we will not get any information if we only have 16 pages. Using an 8-bit counter we can go from page 16-17 and from 17-16. That is because of that with standard two 4-bit counters, with an overflow output going to the +input of the other then, when you tryes to go from 17-16 you will go from 17 to about 30.
