Many times Wyatt and I exchange notes through the use of the same software. The software is basically free. He just gives you a registration # to enter into a line in the program and sends you the connector to plug your laptop into your car.
You may be able to inquire with him whether this software would be compatible to obd-1. By telling him I was a DSM member, I was given a discount and bought his package for $88 if I remember correctly.
