Talk Of Building A Computer...

There's a Java applet that simulates the Turing machine... not to handsome, as
Applets go, but you can program it, etc. If you try hard enough, you've got
to get it right........ (There's always the afterlife...) And the truth is
that as far as memory is concerned, it always gets faster, cheaper and bigger,
within a few months, if not at the same time. Now, there are exceptions, such
as the South East Asia production cuts, but mostly, it's a strait line. As
for processors, I'm convienced that if you wanted to put your money into it,
you could get any amount of power you wanted (Well, there's the speed of
light) but we're talking barn, or even skyscraper size here.... you'ld need it
in the Arctic Circle (Or Antarctic Circle) to keep the thing cooled, and
you'ld need the Tropics to keep the thing warm enough to just "start up".
    But anyway, yes, I do have only the most BASIC KNOWLEDGE of the actual
inner workings of a computer.... I pretty much started caring with the
invention of a ZIF socket for the mainstream (cheap) market... so I'm not
really an old hand at this, but it seems that there MUST be a way to make a
simple, efficent (I mean that you spend days, or weeks/months, not decades
building this), and size effective (As in my house, not my block) way to do
this... wouldn't it be neet if you could make a fairly complex AI program for
something like the Virtual Pet (Tomagatchi) (Same size).

PS- I've been looking for this for months. Does anyone know where I can find
the latest version of Elisa (Or another good AI) on the net? Elsewhere?
