How many transistors would a physical implementation of the Jack computer require?

Just curious.

Edit: Or if the question is easier to answer: how many physical NAND gates would be required in a physical implementation of the whole computer?

The total size of the Hack Computer is primarily for the memory requirement: 256 Kbits for RAM, 128 Kbits for Screen and 512 Kbits for ROM.

The CPU can be done in 1160 2-input Nand gates. In CMOS, each Nand requires 4 transistors.

An actual CMOS implementation could take advantage of other logical gate types, and transmission gates, to substantially reduce the transistor count.
