Maybe not exactly what you wanted because I'm using the HP-48G but it might lead you into the right direction.
I created a function $$F(t):\mathbb{R}\rightarrow\mathbb{C}$$:
Code:
\<< \-> t   \<< P     'x(t)' EVAL     'y(t)' EVAL     'z(t)' EVAL     \->V3 *     V\-> R\->C   \>> \>>
Save this as F.

These are the 3 functions for a helix as an example:
Code:
\<< \-> t 'COS(t)' \>>
Save this as x.

Code:
\<< \-> t 'SIN(t)' \>>
Save this as y.

Code:
\<< \-> t 'h*t' \>>
Save this as z. You can save 0.1 in h or change that later.

For the projection P I used:
Code:
[[  1 1 1  ]  [ -1 1 1  ]]
But you might want to use two vectors that are orthonormal instead.

Now in the PLOT menu set:
TYPE: Parametric
EQ: 'F(X)'
INDEP: X

You may choose other values for LO and HI in the OPTS sub-menu.

With this I got the following picture:
