And in that case, say for an Atari or an Amiga, there
are so many
complex custom chips in there, a beginner isn't going to get much of an
education out of it.
I do agree with Dave. I have some "ready to run systems" like an Amiga,
or a Genesis/Mega Drive, or a mac. But the fun is to understand how it works
AND build it. I have not much use for a 68000 system, nor its assembly, but
I just want to learn :o)
