I have a short story related to memory upgrading.


There is a sophomore at my high school who has done many hardware upgrades
to his TI-85. I don't doubt his expertise at electronics-he has a turbo
switch and is an ham radio operator. Today he told me he upgraded his
memory by adding a chip. I didn't catch how he did it but he used the word
"parallel". There was nothing on the link port. On examining his
calculator, there was a string variable named "B" with a size of about 50
K. This is where the extra memory was. He said a assembly program could
access this memory.


"Great," you say. "So how did he do it?"


That's the problem. This kid is a little wierd. He has his calculator
password-protected so nobody "steals" his games. He also says he
"link-locks" his programs so they can't be copied. To put it simply, his
line of thinking is the opposite of a classic "hacker"--he HATES the "free
flow of information." He wants to charge for everything, and he has no
intention of supplying information on his memory upgrade. Incidentally, he
also plans to make a working wireless link "just for himself."


Anyways, if this is for real, someone else may want to look into this more.
Can this memory be used for something? He wasn't using it when I looked at
his calc, he just said it COULD be used.


On the other hand, he could have put one over on me with a fake memory
screen of something. Thins was my inital instinct, being the cynical person
that I am.


Any thoughts?
