I believe it was 1996 that most cars went to a new computer system . (OBD II ? )
So of course new scan tools will not work on a 1992 .
The guy that does this test , probably wasn't even born in 1996 .

I don't think any of the newer scan tools will work with cars older than 1996 .
The earliest computer system I can recall was the CCC ( computer control command ) system on 1982 GM cars .
It was so simple that you needed nothing more than a paper clip stuffed into two terminals of the ALDL , turn the ignition switch on and count the flashes of the " check engine " light .

Everything with OBDI is hit and miss. Those were dark days.
Why would you need a bi-directional unit for an OBDI car? You're not going to get new firmware or tunes from anywhere. If you're hacking the car then you're better off building your own adapters.

OBD-II was 1996. OBD-I started in '91, although it's fair to state that OBD-I was barely a standard, not universally implemented, and wildly incompatible between makes. A bunch of higher end systems advertise OBD-I compatibility and tend to come with 6+ adapters for the different connectors used in the early 90's.

It's been a loooooong time since I even had an OBDI car, so I have no idea what works and what doesn't now.
I'm currently using products from Autel and their documents are pretty reliable. I'm pretty certain they have an online lookup that will tell you if a tool is compatible with a car, and they are mid-range priced. If I remember correctly they do have a couple of combination kits that include OBDI adapters.
