The obd1 is a very simple computer... There isn't more than a hundred codes in it.....it is not the complex computers you see in the obd2 and newer vehicles.
 
You you use a paper clip and insert it into the a and b ports. you can read the flashes from the check engine lite...code 12 is flash pause flash flash...which is the every things ok code.

Actron makes a code reader which supports most GM OBD systems including that on an 82. The Actron PN is CP9001.
