Last time I heard, their custom chips don't have enough address bits to access more memory than it comes with. A big design botch, as far as I'm concerned. Megabit chips are definitely on the way, but they probably won't be real useful in today's Amiga. > 4.

Hello, I just recieved an Amiga to compliment my mac I currently own. I think the Amiga graphics/color/sound are great!!!!! I have done alot of programming on the Mac, so now must reenter 'MASS LEARN MODE' for the Amiga, but, what the heck.... Having a DOS environment with batch capabilities on the Amiga is very nice, I wish the Mac had it. Anyway, just thought I would let everyone know, someone DOES have both systems.
