That's an old OBD system. You'd need an OBD scan tool to connect to the ECM under the hood. (make sure it's not an OBD-II scan tool, those didn't come around till '96)
You can also retrieve codes on the dash with no scanner, using the 'key trick' and counting light blinks like this video shows:

An OBD1 scanner will do code reading and limited data stream. But as far as hooking it up to a laptop or smartphone it isn't possible. You cant do flash programming with a computer on OBD 1. That is why OBD2 was created so the dealer could easily perform software updates.
