    A nand gate takes 2 transistors. So 554,000 transistors if this were manufactured in a physical device.

    By way of comparison, the Intel i386 had 275,000 transistors.

      Most of the gate budget here is on SRAM used for system memory and video memory, so not exactly comparable to a i386 which had neither on-die.

      4 transistors for a two-input NAND gate in CMOS.

        1 transistor for DTL... certainly CMOS is more relevant.

      ARM1 was only 25,000 transistors.
