Gee, good question. I know people replicate them in FPGAs and verilog [1]. Improving on the design can be potentially done through software with verilog. I'm no

Gee, good question. I know people replicate them in FPGAs and verilog [1]. Improving on the design can be potentially done through software with verilog. I'm not sure of anyone who has improved on it because people focus on replicating it (it's a really fun chip to play with). Why fewer transistors though?
