    Hey guys,

    This is off topic and i dont care if it wastes space!
    For years i never got CMOS based circuits to work, they are really demanding chips. Make sure all the pincs go either to high or low, pull downs and decouplers.

    Well, last night (about 10:30PM) i finally finished my 4 bit (ALU) and i sent the instruction 1+0 to see if it would work, the answer, 1!

    I am over the moon, my first working project, i cried for hours afterwards in joy. Oh, and that 4bit project i was working on, i have stopped that because im designing a better one with goto's and if's.

    PS, are bit-shifts that important?

    With bit shifts you can perform multiplication and division, count the number of zeros oe ones etc.

    In other words, yes.

    Something you might try is to duplicate the function with software. If it can't be done it proves the necessity of it.

    Congrats for getting her done, no mean feat.
