In the U.S., ODB-I was mandated beginning in model year 1988, and ODB-II was mandated for all cars beginning in model year 1996. Technically, California mandated it, but the manufacturers all made their entire U.S. models comply with California rules for easier logistics.
ODB-I had terrible standardization and requires a bunch of model/make specific stuff to properly interface with, but in theory the 35-year old cars do have some kind of data port available.
Oops, most of my cars are 1985. more like 40 years old now. I do have a 1989 Ford Ranger but it has some special proprietary data port and when I bought the special reader it wouldn’t read. I have to use BRAIN POWER to keep it running.
Thanks (speeduino) but…all my cars are 35 years old. No data port available.

Nice, but speeduino can so completely replace the computer of a car it can add the data port to a car without one.
This could be you with speeduino
