[comp.sys.handhelds] HP-48SX Equation Library Card

madler@piglet.caltech.edu (Mark Adler) (08/01/90)

I just got an Equation Library Card, and I like it except for one very
annoying "feature".  Everytime you turn on the calculator, it spends
some time doing something (I guess attaching the library).  (It also
spends some time when you turn the thing off, but that doesn't matter.)
This wouldn't be so bad, if it weren't for the fact that the keyboard
strokes from that time are lost or never read.  I'm used to using my
calculator by hitting the ON key and immediately hitting the numbers
and operations as one continuous stream of keys.  This no longer works.
I now have to wait about 1/2 a second before doing anything.  Very
annoying.  It would be okay if the keyboard queue worked during that
time.

Also, a warning for others: DON'T PLAY THE MINEHUNT GAME.  Don't even
look at it if you value your time.  I thought I had relatively good
willpower when it came to computer games, but I played that darned
game for hours, and I still catch myself doing it all the time.  It's
amazingly addictive for something so simple.

What MineHunt game?  Does this come with the card, or is it available from some
FTP site?

I've been thinking about getting an Equation Library Card, but I've been
holding back until I can determine exactly what it contains that will be
of use to me.  Could someone post a "specific" list of what the card
does (or does not) include -- for my purposes, the list would not have to
be 100% complete.  I just want to know more what I've been able to learn
from HP adds.

Of use to me would be applications to the following:  s-plane, z-plane,
electrical engineering equations, Digital Signal Processing, root-locus,
control systems equations, electrical constants and units, physics
contstants and units, etc....

Thanks...

The mine-hunt game IS included on the Library card....

The extra wakeup time Mark refers to is dependent on the total amount of
memory plugged into the HP 48SX, and is not specific to the Equation
Library.  When the 48 is turned off, it computes checksums for all of
memory; when it's turned on, it recomputes the checksums to find out
whether memory contents have changed, requiring additional memory
integrity checks and reconfiguration.

The Equation Library does have configuration code that auto-attaches its
libraries to the home directory, but the execution time is negligible.

Some people seem tohave forgotten their classics
It should have read (to be correct):
