Its great to hear good comments about Diablo after all these years, ..thank you!
I have to say that I really don't remember receiving anything for the ADAM. and Royalties from Extended Software were really next to nothing.
Actually, I only heard of Image Microcorp when I read this article last week,,lol. But I have seen other versions around too that I wasn't involved in.
You will notice that my name is not mentioned on the credits for the ADAM, as it is on most other platforms.
There was even a macintosh version, however it didn't make it to the market.
