- ALG48 is a symbolic math library, and also provides a good amount of
number theory functions.
- Erable is also another great symbolic math library (probably more
suited for your differential equations class than ALG48). The latest
version is actually not on www.hpcalc.org; however you can get to the
page with the latest version using the link provided by www.hpcalc.org
- Eqstk is the bare-bones algebraic stack. It is much faster than Java
and the current version of SpeedUI. Both of these programs encapsulate
real numbers within a symbolic, which really slows down the rendering.
- Jazz is a great programming library (machine language, sys-rpl,
debuggers, etc). The latest version still has a few bugs in it; I
submitted a bugfix update a few days ago.
- SpeedUI will speed up the interface a bit. The key handling is
almost as fast the built-in interface. On the other hand, you will
notice that the editor will respond much faster.

Great, thanks a lot for your reply. I guess that over the period of 10
years things could have changed a bit. You are saying that currently
worthwhile stuff is:
ALG48, Erable, Eqstk, Jazz, SpeedUI
I have dug up my 10 years old archives, and found a backup copy of my
hp48g libraries that I was using years ago, those are:
I have no idea what I was using them for :) I can only recognize that
currently I won't be needing FEM.
I can see that Alg48 remains useful - I'll download the latest
If you recognize any others of those, perhaps you could tell me about
their newest replacements.

Why SpeedUI isn't listed on http://www.hpcalc.org/best.php ?

The SpeedUI version 9.08 will include your suggested change
for speeding up decompiling real number in algebraics,
so that should help. (Yes, I have read your related posting;-)

Thanks a lot. with hptalx I uploaded SpeedUI and UFL3, I guess that
after few weeks I'll be back on track and try what libraries I need.
Another question is there any real difference between having port 1
merged or not? I have two 128kb chips soldered onto motherboard. One
above another, with their legs connected to each other.
I can only see that with port 1 merged the 'MEM' command shows more
free memory. But what else? Something affecting battery life maybe? (I
vaguely remember that the sole adding of 2nd 128kb chip decreased
