I ran EForth under Muxleq (multiplexed subleq) under an n270 Atom (32 bits Intel) and was fast enough. Much slower than GForth or even PFE (which is slow compared to GForth), but usable even to do Algebra exercises. Rendering a Mandelbrot fractal (ASCII) lasted half a minute but it's amazing that few lines of C enable you to run a Forth with input composed of numbers. I even have a backup in paper.

I did some syntax changes for floats and that's it.
