Im pretty shure he knows the difference, the thing is that on the ti89 with 1.x
rom it works quite similar like RAM. (ie cleared at reset and so)
or.. hmm.. now that I read his mail again, I can see that he doesnt.. but
anyway, here is the reason that archive exists:
archive memory is basicly the part of the flashrom that is not used for the
calculator OS. It is not a extra chip or anything.
So, TI figured, that instead of just wasting that part, they let the user store
his/her own stuff in it. quite nice actually. however, they could have done it
better, so it is kept in case of reset. But they made it easy for them, and let
the "VAT" handle the flash too.
if it is true, that they will fix that in 2.00, that is great!
then we will have easy ways to store applications, like oncalc assemblers that
everyone seems to want. But I dont think they will..  more probably, you will
have to use the tools from ti, and then send it in to them, for approval and
have it as an applet or whatever they call it.
But I don't know.. I havn't kept up to date with ti's doings lately.
