For what it's worth there is a virus for the HP48.  It attatches
itself to a program and when you transfer a program to another hp48
it goes along.  It doesn't really care, if I remember right, what
program you send.  It manages to send a copy of itself.  Resetting
the calculator doesn't help.  Of course a resent on the hp doesn't
necessarily clear memory.  Clearing memory will get rid of it probably.


I don't know if this could or couldn't be done on a TI but I suspect
it could.  Since there isn't an infrared port there probably isn't
nearly as much file transferring going on.
