The first computer I owned was a Heathkit H-89 that I assembled from a kit.  I still have it gathering dust in my garage.  It stopped working a long time ago.  But it had not one, but two Zilog Z80 microprocessors.  I pretty much taught myself assembly language on that machine as a teenager.

After all these years the venerable Z80 is gone.  Quite a run though.  From The Register.

The chip that changed my world – and yours
