MPE runs on HP/3000s, or, as they call them now, e3000s.
I like it that HP keeps documentation online.
Although I use Python daily in Phaseit's consulting practice, I haven't had occasion yet to try Python/iX, nor Perl/iX, although I'm also expert in Perl. C is the single language in which I'm most experience, but, again, I've never used it under MPE.
