They are spot-on with the transistor count for the CPU (though I believe it doesn't include all your RAM registers). SERV is a serial CPU that can range from doing calculations just 1 bit at a time up to doing them 4 bits at a time. https://github.com/olofk/serv https://github.com/olofk/serv It's pretty incredible considering the 6502 was already considered tiny when it was released with just ~4500 gates vs the 6500 in the 8085 and the 8500 in the z80.
