Its commercial success doesn't make it a good architecture. ;)

Huh?? Except for perhaps SPARC, PowerPC, MIPS, Itanium, Alpha,
ARM...And then only if you're restricting your view to things that you
can buy *brand new* today. "The masses" can even pick up something like
a PDP-11 pretty much any time on eBay.

I love hacking with Z80s. I consider myself very lucky that much of
my work these days is done in the embedded systems world, where Z80s
(albeit at 50MHz with 24-bit address buses) are alive and well. It's
neat to see how it has made the transition from mainstream
general-purpose processor to common embedded processor. (and I'll bet
Zilog sure is happy about it!)
I remember the Adam...what a neat machine. A friend in high school
had one. I remember being utterly fascinated by those cassette
drives...cassettes as a file-structured medium? Neat!
