Oh, yes... the "Walden" simulation (speaking informally). I'd like to put my hands on these stuff, yo can be sure. But seriously: these efforts from Noel and Paul (Congratulations) deserves to be reflected in an IMP hardware simulator under SIMH (at least), both the interfaces and the IMP itself. And at least I do not care if it goes slower than hell.
