Lots of half-gates means lots of pulldown/pullup resistors. Probably uses a ton of power (per bit, or whatever.) We had to build a full 16-bit machine in schoo

Lots of half-gates means lots of pulldown/pullup resistors. Probably uses a ton of power (per bit, or whatever.) We had to build a full 16-bit machine in school. Thankfully, we were allowed to use 290x ALU slices.
