Rare AGI Games on standard PC DOS

[Threepwang]

My title says 'rare', but I could have used 'untraceable' or 'nonexistent'. I don't know.

Please, I would like to know if the following games exist on standard PC DOS or only on PC BOOSTER and PCJr?

They are:
-King's Quest 1, Game version 1.0U, Interpreter version 2.272.
-King's Quest 2, Game version 1.0W and 1.1H.
-The Black Cauldron, 1.1J, 1.1K, and 1.1M.

I sent a DM to @lance.ewing, but he hasn't been around for a while; I hope he's doing well. I'm just a simple translator and I don't have your knowledge; I hope you can provide the answer.

P.S.: I'm testing the existing versions: https://github.com/Thpwg/AGI-SCI-index If you see any mistakes on my part, please feel free to point them out, and I will make the corrections.

Interpreter version 2.272 can?t be a booter. The booter used GAL (which I *think* was called AGI0 also?).
As for TBC, we have the source code for it! - so we know that it builds on regular AGI, at least.
