Seems that python2.7 (the default version on westkill) works here.
This is still unsatisfactory mainly because it is too slow.

j0.py is as far as we got in translating the BASIC 
program. We're stuck at the endless loop. 

j1.py is stuck on defining rnd()

so j2.py works, but does not leave anything behind.
We need to fix pset(x,y).

and j3.py works using dot() in pset, and hideturtle()

fixed an error in translation and rescaled things for j4.py
for j5.py move the definition of pset outside the loop, no speedup

j6.py is the end of the line, and the speedup has been negligible.
So we're at the end of the line.
