    Is there any possible way to use only NAND and NOT gate to make a OR or NOR gate?

    thanks!

    Yes. For an OR-gate take two NOT-gates (or two NAND-gates with the inputs tied together) and feed the outputs to the inputs of a NAND-gate. For the NOR-gate just cascade a NOT-gate (or NAND-gate with inputs tied together) on the end.

    Univac made the first transistor computer with all NOR gates. They changed to NAND gates for the next model.
