    So you are claiming that the videos showing the 68k core for FPGA running at a speed equal to a 200MHz 68000 CPU are fakes?

    A 200MHz 68000 is not particularly fast ;)

    Depends on what you are comparing it to. Compared to a 7MHz 68000, the 200MHz+ 68k FPGA core with some 68020 instructions added is fairly impressive. What if they can get it to run at 400MHz to 500MHz, or faster?

    When compared to my 2.7GHz G5 PowerMac tower, it is still slow, but much less difference than the wide gap between 7MHz and 2.7GHz.

    But I still think that it is interesting to see what can be run using a fast FPGA with the 68k Apollo core. It may be that if/when the Apollo accelerator card(s) are released, original Amiga hardware might be able to run a decent web browser, as well as productivity software (if any is ported or written from scratch) and more demanding games that were not previously possible, even on an Amiga with a 68060. The Apollo team has stated that they also plan to provide improved graphic capabilities, but I don't know exactly what they have in mind, and I am sure it won't compete with modern video cards. This is going way off topic, and I really don't want to speculate on what might happen if/when the Apollo core is widely available, but IMO, it is interesting to me and a lot of existing Amiga users.

    Hi David,
    I'm not trying to incite anyone's ire or call anyone a liar.
    Some of the last' 060s were capable of running at 75 to 100MHz.
    The '40 and' 60 cores are vastly superior to the original 68000, running circles around them at similar clock speeds.
    So, a 200KHz FPGA 68000 may not out perform an overclocked 68060.
    However, if we are willing to spend more for larger, faster FPGA AND we aim at a more competent core that will change.

    And I am glad to see the Apollo team actually releasing their work to the public.
    It lends them credibility that other projects have lacked.
