Back in the late-80s when I was a kid, I was fascinated by both the ST and Amiga. I bought several books about them and read everything I could find about their internals in computer magazines.
Unfortunately, my knowledge remained theoretical as they were too expensive for me. I had to invent tricks and find ways with the Z80 of my cheap home computer to simulate the marvels that could run on these 68000 power-horses!
It was a great, yet tedious exercise. I owe a lot to the nights spent trying to emulate some feature of the Amiga or the ST on my limited Z80 machine.
