Without a scanner you can get pre-OBD2 codes, and apparently even some OBD2 codes with a simple piece of wire jumping a small blue 2P connector, key in ON position, and counting the long and short flashes of the CEL on the car's instrument panel:

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
