Omph,
Its close enough to the Early HP detachable cord and yes if thats
done (could not scream nooo loud or fast enough) the result is
both load and spectacular.
I forget the ideal voltage though. The only transformer are
ones floating loose are the 4pin plug versions. But there
are TI 99/4A sites on the net with all that.
I have a crate of 8" used and a box or two of NIB. They seem
to last if they don't say noname or Memorex blackwatch ;)
I use them more for RX01/02.

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).
If somebody found a mains cord that "fits" and plugged it in with the
low voltage AC input connected to the wall, then it might not be happy now.
You might want to avail yourself of some of Allison's expertise.
Might I suggest a box of 8" floppies for XMAS?
