Is anyone interested with the Z80?

COMPACT
COMPACT over 10 years ago

The Z80 is still manufactured today and I was wondering whether there is any interest for a community or discussion group.

    What sort of things would you discuss - Z80 has such poor performance compared with modern processors that surely no one would use one in  a new project ?

    Would you believe the Z80 is still in production today?

    I know it's still being made but so are spares for Ford Model T !

     

    My question was about using one in a new project, is there any reason why one would ?

    So what's watching the watchdogs, and what's watching the watchdog's watchdogs, and what's watching the watchdog's watchdog's watchdog?.....

     

    A zap of uncontrolled ESD can put it all at risk.

     

    How did Toyota and other car manufacturers get some of their code so wrong to cause safety issues?

    MISRA standards are only a starting point.

    Safety Applications?

    What would you be looking at doing? Most off the shelf safety controllers used in industrial applications that require certification (very few safety applications don't!) are dual processors with watchdogs to each from each to ensure that it all behaves according to plan.

     

    If you want to certify this application for use then there is a very long road ahead to get certification to the relevant standards.

    Programmable logic doesn't count because it can be applied to both!

    I'll raise your 50MHz ........

    re provability  - I told you no one cared - the VIPER was a total flop (and that's about how fast it was image)

     

    It's interesting that when people have built fast versions of old architectures it hasn't turned out to be good business - remember Scenix and the 100MHz PIC ?
