SD: Re: ROM calls and such




We will basically have the functions in the calc's ROM (believe me, there
are tons) and a few of our own design (such as your comparisons and such)
Trig would be nice, but would be better implemented in a data file that
coudl be shared.  Cause if a prog didnt need them, it would be quite a waste
in the OS code to have to be on the calc all the time.
Also, definetly not the VAT.  It depends what we find out about the way the
e2 stores files on it.  If that system is efficient enough, we may just use
that.  We may have to as the e2 microcontroller may deal with finding teh
files on the e2 mem by itslef.  If it just is plan crap, and it could be
done differently, we certainly will do it that way, most likely like the
classic FAT style.
