Hi EAUniW, love the enthusiasm towards a AAA type Amiga architecture. Now that you have gave some basic ideas towards a hardware system. I would now try to gather other people’s ideas of what they might want. I know for me I’d have a few particular requirements, otherwise I’d at this stage go for adding a Vampire card to my system.
I’ll take a few moments before posting my suggestions soon.
Also you need to consider software for this system, unless your making a cheaper Vampire system (I don’t have a Vampire yet)
Sincerely best of luck
