Is the Z80 the greatest processor of all time?

Is the Z80 the greatest processor of all time? 50 years later and it's still being made and used in millions of devices.

    it's primary focus today is as a coprocessor in low power embedded systems or industrial microcontrollers. i doubt consumer devices other then the TI calculators use it at all.

      >other than calc

      well it is found in LCD display systems of alarm clocks, temperature monitors with screens, inside the microwave oven systems..
      that kind of thing

      but in a mobile phone? nope.

    For embedded, yes. For general purpose computing, the 68060 takes the crown.

        z80 != Sharp LR35902. it has some things from 8080 and z80 but the 35902 is not compatible with either chip.

      I agree that it's a pretty good processor. It's based off the 8080 after all. However I think we should encourage the use of the ez80.
      The Aigon Light has the ez80 on board and it needs an OS that can take advantage of the 512KB of RAM it has.

      This looks really cool, but the task manager having vertical trace instead of horizontal is a fricking moronic design decision.

      I've been sorely tempted to pick one of these up, the idea of making software on a system that I can understand holistically is incredibly tempting.

    The Z80 is okay but the greatest processor of all time is this thing right here. Pretty sure it's also still being made and used albeit in a slightly updated variant.

      About 200 million annually with a license from WDC, plus an unknown volume from alternative providers.
      > and used albeit in a slightly updated variant.
      Not much, really, though a few things could be done.

        Don't they mostly manufacture WDC 65C02s nowadays?

          Probably, but since nearly all is for embedded use (mouse, pacemakers etc.) it is hard to know. Others, like Sitronix, have their own variants built upon 65C02.

          The original core instructions in 6502 (no "C") remains constant from what I can see, and then the free instruction slots were filled differently by various companies. You also have more radical variants such as 6519 optimized for Forth.

            Yeah, that's why I thought it was fair to say the 6502 is still in use, even if it's not exactly identical to the 80s one.

            The 6502 (and 65C02) is very responsive with interrupts and code is rather compact. I think it would have been a greater competitor to AVR had WDC had a wider portfolio of IO chips. Even today it is hard to get a 6502 type chip with memory and plenty of IO in a convenient package.

          yeah, and 16bit version too, i think. (65816)

          6502 will forever be in use. great instruction set, well documented and understood, delivers what it's expected of it. similar story with 68000 and z80. they'll be around and found in products long after we're all dead.

            Supposedly the code is denser than for 68K, yet nobody ported unix like OS to it from what I can see. Also it looked like a 6502 that was stretched to 16 bits but without the elegance of the normal 6502.
            I am still disappointed that a 65000 with 32 bit architecture was never made.

    No, it's just low tier tech and perhaps radiation resistant. You could probably use vacuum tube satellites in space and call them "greatest". Ruggedized and stupid is not "greatest".
