In article <15343@cbmvax.commodore.com> you write:

OK, so I'm a total ignorant when it comes to hardware, sorry... :o)

What IS the not so simple answer, then? Don't tell me Commodore doesn't look upon the custom chips speed as a problem. I certainly do. I didn't mean to flame Commodore (or you) in my article, I just think it's kind of stupid to have a custom graphics chip that performs worse than a general purpose CPU (68030). Well that's my opinion... I LOVE graphics animations, and I want mine to be FAST. I'd just like the Amiga to blow away the competition completely, OK? :-) Well I guess people would buy Macs and other









 inferior hardware/software combinations anyway. Shame on them!

Sorry for being such a pain in the ***.
