I was discussing the TT with one of my friends today, and the question
came up about how the memory in the TT is configured to get 26 meg out of
4 mb simms.  26 seems like an odd number - especially with a 32-bit data
bus on the '030.  With 4 mb simms on a thirty-two bit bus, you get banks
of 16 mb.  Is part of the memory configured at 16 bits?

I would also like to add my thanks to KenB and the others at Atari for being
here on the net.  That's one reason I'm sticking with Atari and am eagerly
awaiting the US release of the TT.  Keep up the great work guys!

Happy Holidays to all on the net!
