Re: A92: Rom dump?
What they mean is a backup image of the 92. If you have a
GraphLink cable (which should be available from the same
place at which your 92 was purchased), you can download
the 92 GraphLink software from the TI Web Site and be able
to send and recieve data from the calculator. One of the things
that you can send and recieve is a backup of the calculator.
When they say "Rom Dump", they mean a backup of the 92.
There are 12 versions of the 92 in the US, and you can only
restore the version you have. In a nutshell, what Fargo does
is play off of a bug in the 92 GraphLink software. David Ellsworth
figured out that if he did a backup of his 92, and then stuck
some machine code at the end of it, he could send the whole
thing to the 92. When the 92 hits the end of memory, it starts
overwriting the first sectors of memory, which allows him
virtually unlimited access to all areas of the calculator - some
of which we really wish he didn't!! But as other Fargo programmers
have experimented from time to time with the same phenomenon,
they occasionally screw up their backup. The 92 will only allow
a backup of the same version to be restored to the calc, so that
is why you will see people calling for a rom dump of a particular
version. To see which version you have, from the home screen,
press <F5>, then the green diamond, and then the <(> key. To
get back to the home screen, press <APPS> and then <ENTER>.
