The (lack of) latency is probably the most difficult part to reproduce not just emulation, but with a modern hardware+software stack period. It’s not necessary to go back as far as the Mac Classic to get that though, anything that can boot Mac OS 9 (including a few that can hacked to run it, like the G4 Mini) will get you that too. When I boot up my PowerBook G3 the sheer responsiveness when typing immediately stands out.
