I've just hit publish on a post about the history of the original Amiga, more from the perspective of the story of Jack Tramiel than the technology. The platform I use limits links and embedded images and videos as well as length as it's also a mailing list. I'm also very aware that a lot of the information around is muddled and changes depending on who you talk to, so please be aware that accuracy isn't always going to be 100%. A lot of what happened is disputed and we'll never really know.
Still, if you'd like to take a look, Crash and Burn: The Amiga ST Story is here.
