There is some wonderousness that they completed the emulation enough to run something complicated like linux. Its very easy to use something limited, say a HP48 in RPN mode and some arrays as "memory" and variables as registers to implement a couple opcodes of say a 68hc11. I did that around '93 or so when the 'hc11 was contemporary (its ancient history now, but it was kind of a 6809-like microcontroller with pretty good specs for the era) On the other hand its hard to get a complete emulator working of everything, or at least close enough to everything to boot a major software project on top of it. Sort of like implement a system/360 emulator that only does opcode ADD, well, ok cool, but when you can boot MVS/360 thats a whole nother level of wow.
