Hi Conan!

Have you seen the entries lists that were posted by Mika Heiskenan to
seq.uncwil.edu in the hp48/Uploads directory?  These lists contain many
commented entry, both supported and unsupported (by hP, that is).  These
"entries" lists are a valuable tool for exploring the various
undocumented sys-RPL commands.  For example, entries.3+ (I think this is
the latest, although I think Mika has made one in entries.a format for
use with the RPL tools) has the entry at 40828 (PTR 40828) described as:

::  TakeOverGETPORC
@  get object bound to menu key (key number follows)

The (::) in the above example indicates that the entrie is an RPL
program and the name (TakeOverGETPROC) was made up by whoever discovered
this particular entry, I guess.  The (@) indicates that the following is
a comment regarding the function of the address.  Many, many entries are
covered in these lists (Thanks, Mika!) to varying degrees of
thouroughness.  Some are left to you to decipher.

This can be done using the <-RPL-> library for RPL routines and MLDL for
machine code routines (at least that's how I've been doing it).  To use
the rpl library, let's take PTR 40828 as an example.

1: "PTR 40828" ->RPL  --->   1: "82840"

where ->RPL is in the <-RPL-> library.  "82840" is merely the address of
the pointer in a string and reversed.  So, you can type the string in
directly if you like.  Next,

$->  --->  1: External External

where $-> is a command in the RPL library.  What has just happened is
that the $-> routine has just put whatever is at the address in the
string (backwards, that is) on the stack.  Now, you can decompile that
with the RPL-> command to get

1:  " :: TakeOver 'R GETPROC ; "

Now you may have to dig deeper to figure out GETPROC, but that's the fun.
 Eventually, all the commands lead to machine language routines and
that's another story.  But, usually you can figure out what is going on
before you run into ML.  If not, try MLDL for some more fun!

Combining all the above tools, you can learn a lot about this machine and
how HP programmers think.  Keep in mind, I am NOT an expert at this.  In
fact, when I started playing with this stuff about six months ago, I
didn't even know what machine language was!  I am just an ignorant
aerospace engineer who didn't get enough comp sci in school.  But, I have
learned plenty from this machine.  Primarily, I've learned how little I
know.  But I am having fun!

I hope all this helps.  Let me know

I believe that the hpbbs does not directly tie to comp.sys or comp.sourc
etc. conferences.  I suspect that they copy files from/to these bbs as a
batch overnight or something.  I also suspect that some of the files
which were to be updated got blown away.  i.e. comp.sources no longer

I don't know if this is related to your problems with missing memory
but...

A while back I had an unexpecte warm start during the debugging of a
sys_RPL program.  After this event, I too noticed missing memory.  AS I
investigated, I found that the contents of the Equation Library Card I
had in port 2 had been copied to port 0 (at least part of it!).  And
these libraries had been attached during the warm start.  So I had to 
detach and delete each one and that recovered my missing memory.  I
posted a question to c.s.hp48 out of curiosity to see if anyone knew
anything and didn't hear anything so I figured it was just an aberition
but I'm still curious.

Yes, it draws the minimum power possible while retaining memory, however
it also shuts off the time clock.  HP ships the 48 this way.

Yes, it's possible!  Coma mode turns off the HP's internal clock, so that even
less battery power is used.  Supposedly when you first buy a new HP48, it will
be in coma mode so they have a longer shelf life (can you imagine having an
expiration date on hardware?)

Yes, I know.

The spreadsheet is named Omnibus (TM) and is an application for
the SmartROM (built-in).

What is the SmartROM ?
The SmartROM is a library containing hundreds of commands available
from EduCALC in USA and from ForCALC in Europe.

What the actual price is, I cannot guarantee because I got some
feeback from EduCALC mismatching with feedback from users.
It should be 119.95$ after a rebate but somebody told me that it is 169.95 yet.
Surely, the latest catalog still reports 169.95.

This fact is my only concern with the SmartROM.

If anybody could confirm whichever price is currently
applied, I would be most grateful.

There is a program on seq.uncwil.edu that converts GROBs to TIFF files.
The only problem is that when I tried to get it a few months ago, I
found out it was corrupted. Someone from HP sent me a working version
and I think he was going to put it on seq.u.e but I'm not sure if he
got around to it. Basically, try to get that one and if you have trouble,
I can send you my version.

I did do the ':IO: filename' restore thing.  The thing I might have
screwed up was the settings on the recving computer.  I backed it
up once with the computer configs set for binary and the other with
the configs set for ascii but now neither of them work properly.  What
I mean is that when I download from the mac to the hp48 they arrive
as strings instead of backup objects.  Am I setting something improperly?

Its pretty good for programming.  Its like the Microsoft "Quick" language
interface and is pretty solid.  A few of the features that I like are
being able to put up all the characters without having to resort to
codes, etc.  The remote host mode works quicker than the kermit method
and downloading is quicker.  The system is a little hard to grasp at
first and the docs are pretty thin.  The system is based on applications
which include variables programs etc.  Overall I think its pretty decent.
If you don't do programming you don't need it, though it would probably
help you learn to program easiser.  My two bits... ;-)

Yes.. this version of tetris is indeed the one that was supressed before.
Tetris was written for the hp48sx very early at HP.  And then as one might
expect it was found to be pretty popular.  A goodly number of the hp48sx
hacks there got copies.  Unfortunately at least one copy got out and this
I presume is the one you have.

Anyway, I've been waiting a long time to talk about it.  I'm glad it's 
out and available.  Joe Horn listed all the features but I'd like to 
comment that everything was done very well.  I don't believe anyone is
going to find any bugs in this software. A few points to comment on.
- As Joe stated two player mode is sweet.  Found my hp to hp connector quite 
useful for this purpose.

- It's very fast, and the higher levels are pretty scary, but you have 
further to go unlike the other machine language tetris.  

- The scoring is consistent with the original game if I recall correctly.
Sometimes it's better just to start at higher levels because not as many
points are available at lower levels unless you can take out multiple rows
all the time.

- Changing the key layout is very intuitive and simple to do.

Overall it's a quality bit of software.

I just hope people aren't so burned out on tetris games for the h48sx
that this one doesn't go over well.  I think it'll be a hit eventually.

Heelo threre!ere!Hi There!

CR/LF is an abbreviation for LineCarrage Return/Line Feed, ie. the
key on your calc that is the  right-shifted 2nd, 3rd or 4th key on
 the bottom row of your calc (I don't have my calc with me just now
so cant check exactly which key it is, and my memory's just given out!)
It's the key with the curving, leftward pointing arrow above it.

There are also many other similar programs on the other Goodies Disks
including (I believe)  an improved version of ROLDX, although this
is still the one that I use.

There's a conference called q_and_a and a a few FAQ archive files at
anonymous ftp seq.uncwil.edu   (128.109.221.20) also you should read
back postings and buy the other Goodies Disks or download them for free
from the above ftp site in directory hp48/EduCalc/.

A few months ago, after I changed the batteries in my HP48SX, I've had
what looks like a lowercase `l` (ell) in the top (status) line of the
display. Any ideas?
