Un-Deletable Programs, is it Possible?
Posted 17 October 2002 - 01:05 AM
I heard about the possibility of programs that cannot be deleted when the CFX 9850G Plus is reset.
This would be a valuable asset but i don't know how it is accomplished-
any help would be great.
Thanx in Advance.

When the calculator is reset, the user part of RAM is cleared, so I don't know how one can acheiv that.
Maybe you are confusing it with the Flash Add-ins of the AFX models?

hm, the cfx-9850G has a program-database. in this database are some little helpfull programs from casio. do you mean these programs? they aren't removed if you reset the calc.
just the CFX 9850G "PLUS" has that extra program database. It isn't deleted when the calc is reset however there is no known way so far (except replacing rom etc.) to store data there.
I guess there is no way right now to make progs undeletable.

I don't know if this is what you've read about.

in principle there's no chance to create undeletable programs in the normal program memory. (or am i wrong, martin?)

I dont own that type of calc... so i cant test it.

You are right
(or am i wrong, martin?)
BTW: what about your ROM replacing? Is anything new?

i have to repair the display,too. but this won't be such a big problem. i have a new display (it is an other but it seem to work with the casio) and i have to change it the next time.
