OK, the cord "fits", but having looked at it now I'm not at all convinced, 
either. The two-pin socket is actually the same as the four-pin socket on 
the other two machines, but with the upper two pins (intentionally) missing.

The PSU board inside appears to be a switcher, but I'd be inclined to agree 
with Allison that it's intended to run from low-voltage AC (I've put the 
machine back together now, but just realized that I should have checked the 
voltage rating on the rectifier stage's caps).
