Sometimes, because I don't understand chip design, I wonder why we can't simply make 5nm MOS 6502 or similar chips. Technically I suppose we could design a modern CPU with the 6502 or Z80 instruction sets, but would they be of any use? They should be absolutely tiny and use virtually no power, but would they be compatible with anything?
- bombcar 3y agoThey exist (though today it's so cheap to make CPUs that you can find embedded tiny little CPUs used for one thing that are actually miniature versions of old CPUs).

I don't know the process scale offhand, but they're used all the time in USB to serial chips and other interface type devices. Another example, the Chinese counterfeit Saelea logic analyzers use a 68000 core with a USB phy tacked on
