RE: Free42 and cube root of complex number
The 1984 HP-71 was supporting the signed zero, but it was sometimes a source of confusion for users and the signed zero was not kept in later machines (starting with the 28C).

So yes, the HP-71, with the Math ROM, gives the same (correct) results:
> (-8,0) ^ (1/3)
(1,1.73205080757)
> (-(8,0)) ^ (1/3)
(1,-1.73205080757)
