The pcoder22.s19 is not supposed to be used for the HandyBoard (I think it's for the MIT robotics course). Your HB needs the pcode_hb.s19 (...) (25 years ago, 6-Jul-99, to lugnet.robotics.handyboard)

The output pin of the LM35 gives you the ambient temperature in 10mV/degree C directly. The 47k pullup resistor will form a voltage divider with the output.
