I don't remember all the terminology, but I thought they did come out
with a 16 bit CPU. It was on the 32 bit machine they threw in the
towel. I remember a quote by the chief architect who had also
designed the Z80 basically by hand... after designing the 16 bit CPU
with random logic, something about never doing it again. That was the
days before VHDL and Verilog and every gate had to be put on a
schematic! But then that was how Seymour Cray designed his super
computers.

The Z8 was a quite good 8 bit core, it had the advantage of not being
as early as the 8051, but Zilog were very late bring flash versions,
and they have a lot of very similar variants.
Zilog DID buy a good Compiler tools company, but their truly
appalling web site would never let new customers know that.

Yes, as an example, Rabbit have spun 3 variants of their core, whilst
Zilog only managed a single bug-fix pass of their Z80Acclaim.

Given the truly massive software base the Z80 enjoyed,
even now there is a lot of potential for the Z80 still, but again
Zilog's web site would not let you know that...
[Imagine if they had dropped Turbo Pascal 1.0 in ROM, into a corner
of the Z80Acclaim...]

Agreed.

Z280, Z380, Z80000...

I.e., anything with a 'Z' and an '8' in it seemed doomed!
(well, the Z8000 actually *did* materialize)

Even the Z180 was actually a Hitachi part (HD64180 and
its variants).

Not specifically about Zilog but it is about the Sw /IT /Computing
industry and the complete mess some companies made of a sure fire
success.

The premise is the top dogs are not the top because they are good but
that they made fewer obvious mistakes.

Another interesting read about this subject is "On the Edge: the
Spectacular Rise and Fall of Commodore".
