Be aware of one thing. the old HP penplotters came in two 
variations. The serial driven and an odd parallel type used in 
labaratories with a special daisy chain cable. I got one of 
the last type and had to change the connector  + find another 
kind of driver. It works now but try to get the serial one is 
my suggestion.
