There are 230,400 square inches in a 1,600 sq-ft house. But you are assuming
that you cannot somehow compress the information that you are trying to store.
How many chair legs are in your house? Store the location and size of every
obstruction and you don't necessarily need to have one byte (or even one bit)
per square inch to completely map the place out.
The RCX is roughly comparable in computing power (and 4-16 times faster than) my
old Apple ][ computer. Yet I look at the software that I used to run on that
baby. Even some pretty decent chess programs, but how many possible moves are
there on a chess board? Work smarter, not harder.
I'm not saying that it wouldn't be great to have more memory and a faster CPU,
and I imagine that this is a foregone conclusion in a redesigned RCX 3.0. But I
agree with others here that I'd rather have an affordable RCX than one that can
solve any computing problem that I throw at it. Part of the challenge of any
LEGO modeling is to make do with what you've got.
