I like Peter's approach of using WinUAE with QDOS Classic since it's not double emulation and WinUAE may be the fastest 68K platform out there.
A relevant "double emulation" happens for the screen memory though. I wonder if a QL screen model could be directly implemented in UAE.
Also I wonder about mass storage beyond floppy images.

QDOS for Amiga solves that QL screen-to-Amiga-screen problem by employing the Amiga Copper, if I remember right. I'm no expert in modern Graphics cards, but something similar could possibly be achieved with a simple Shader running on the GPU.

My low-end PC from 2019 with QDOS Classic under UAE:

Thats a pretty hefty "low-end" PC youve got there! Nearly 3x faster than QPC2 on my 8 year old i5 PC and 5x faster than the same PC running Qemulator with Qdos or Minerva at full speed. Either UAE is very good, or your PC is very fast or theres some other magic going on..
UAE is in fact very fast as it uses more than one CPU core to pre-compile 68k code into x86 code in parallel with running the actual 68k emulation. I don't think QPC2 is actually using more than one CPU core.
OK. Thanks for the explanation!
