I had an amiga 500 with hd/memory sidecar and a 1084 monitor. My pc at that time (a 386) was used to run a bbs so the amiga 500 was my main computer for most things.
I wanted to upgrade to an amiga 2000 and run my bbs on that with cnet and have enough proc/ram left over to do my own stuff but never did. It was crazy expensive to get enough hardware to do that at that time.
My two computer setup worked nice for me at that time. The amiga for games, dialing out to other systems and anything I needed to do and the pc to run my bbs.
