Days ago, I posted an article asking questions about HP-28S.  There has 
been a fews responses, which I truly appreciates.  Nevertheless, not all 
of my questions are answered, possibly because many people 
are no longer interested in HP-28S.  But before can afford 
a HP-48SX in my next incarnation, I would like to use my HP-28S 
to its full potential.  So I decide to give the following questions 
another chance:

1)  Do the two books: "Custominzing you HP-28S" and "HP-28S insights" 
substitute or complement each other?  If the answer is the former, which 
one is the better?

2)  How on earth can one change the speed of a HP-28S?  We know its pros and 
cons; now we want to try it ourselves/

3)  In one of the posted articles about HP internals, I remember seeing a 
warning that says improper use of SYSEVAL can result in memory loss or even 
hardware problem.  I do not know how the later is possible.

In addition, I have one more question for all experienced users: what can I 
do to prevent loss, theft, and damage to my HP-28S, especially when I bring 
it to the campus, where it is crowded and confusing?  (For example, punch a 
hole on the upper part of the left-hand leaf and through it chain the 
calculator to my backpack or my wrist.

I appreciate you answers.
