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).
