1994 Accord what type of OBD?

On my 1994 Accord I have found the blue plug 2 pin data link connection (and there is another orange 6 pin connection next to the data link also and don't know what this is). From what I see this model has no OBD 2. Can anyone tell me if if there is software and connection cables available for this system to look at the internal workings of this car (sensors, temperatures, RPM etc..). Or I am only able to read trouble codes with this data link? Thanks
