On: The Agon light is the fastest 8-bit microcomputer

It feels especially silly when it has modern 240 MHz ESP32 instead on-board, as if it is somehow more authentic than a FPGA.

[musicale → zokier]

Presumably you could do a cycle-accurate EZ80 implementation on the ESP32 as well.

If the cycle timing and user-facing I/O pins are the same, the main differences resulting from implementation would presumably be in areas like form factor and power dissipation.

I'm sure I've seen ESP32-based emulators running CP/M (or DOS for that matter) discussed on HN and elsewhere.
