Ironically (and sadly) the Z80 was discontinued not very long after this piece was published.
IIRC, only the classic 40-pin DIP Z80 was discontinued. The eZ80, which is fully compatible, is still in production.
I'm sure clones are still being made.
We still have the venerable 8051 for anyone who likes old architectures!!
