Though it may be that modern Intel or AMD chips do not have enough registers. Somewhere I got the impression that Athlon and AMD and the Pentium chips were RISC chips with a hardware layer which converted Intel instructions to RISC instructions, but that may have changed if it existed.

JIT 6020+ & FPU emulation I suppose the answer depends on what do your customers use the QL for? Probably tinkering and hence the answer neither.
