Apart from the fact that NiCd's are less than ideal for calcs
like the HP48, there is little need to reverse batteries to
drain a capacitor or wait the 8-15 hours or more it may take
to drain it with the batteries out. Find a paperclip, or
other handy dandy conductor and short the leads. Then press
the ON key. I have to do this regularly with my radio because
of the strange voltage properties of NiCd's when low.

I would like to know the opinion of exeperienced 
people out there.

I have used the equation/library card, and I have used the
EE (Electical Engineering card). Not that I own them.

I am thinking to buy one of the cards, but 
I am not sure which one would be the best choice.

As a EE major, I have found the EE card is not much help
and the eq/library card kind of handy.         

I have not have the chance to exploit the full potential of the cards
That is the reason why I need your advice.

so, which one should I get.. 


Thanks for any info.

Actually, what HP Corvallis told me is that they bought back all the dealer
stock, etc., that they could get their hands on and made it disappear.  Maybe
your dealer decided to sell off their stock instead?  Or maybe your order 
came in before their RevB shipment arrived?

Did you have anything stored on the RAM card when you got the "Invalid
Card Data" error? Because I regularly get this error but only when I
have nothing in the card. As soon as you store something in it you 
don't get this error.  When the '48 is switched (generally) it
checks to see what the system is set up as ie, looks to see if RAM
cards are installed (or ROM)  and does any system configurations
required but apparently (I've read this somewhere before) if the 
card is blank it considers it to be "alien" and gives the above error.
Therefore, I don't think it's any great worry.
However, I could be wrong!   [|8-))

     There is some info about how to open the hp48 with relatively little

months ago to install a more common serial connector (1/8" phono jack),
and wrote up that description and uploaded it to seq.  You can get it by

I *know* MEM does garbage collection.  How else could it tell you how
much free memory you have?  Are you sure that when you did your
experiment with the long variable 'aaaaaaaaaaaaaaaa', that you didn't
forget about last argument, last stack, last command line, etc.  If you
didn't turn these off completely, you probably changed that least the
last command function.  Remember that last command save the last *4*
command lines that you entered.  I believe that if you account for all
these hiding places for memory, that you will find that MEM does garbage
collection.

OK, I've looked, even in sysRPL, but I can find no easy way to do what
*should* be an easy operation. How does on insert an object into a
given place in a list? I.e. Insert object ob after the i`th element of
{}:

{} %i ob -> {}'

\<< 3 ROLLD DUP2 GET 1 \->LIST 4 ROLL + REPL \>> 

will do it, but is slow. Exploding the list onto the stack and inserting
the new element then reassembling the list is faster, but complicated. A
sysRPL function I wrote to divide the list in two at the key place, add
the element and join the two halves takes ~70 bytes and still can only do
20 or so simple cases per second.

The prickling in my neck tells me this is way too much trouble. 

What have I missed?

All it takes is a two cent diode to protect against voltage reversal.  I haven't
seen a piece of consumer electronics without this part since I started taking
everything and anything apart 20 years ago.  ( I am aware that disassembling my
hp48 is beyond my skills. ) This diode will also make reversing the battery
completely ineffective for discharging the power supply.  If the reset doesn't
work, leave the batteries out overnight.  This should happen so often that one
can't wait 8 hours for the power supply to discharge.  ( I'm not known for my
patience.... )

Thanks to Sam Liddicott (phudl@csv.warwick.ac.uk), I have regained
my sanity.

Before I made my own user-key assignments, I noticed that RCLKEYS 
returned { S }. I thought this was wrong, because I hadn't made any
user-key assignments, so I "fixed" it by doing 'S' DELKEYS. 

I didn't notice the behavior in my earlier post until later, so I
didn't connect the two.

Aparrently, you need an 'S' in your user-key definitions to give the
user-keyboard keys their default functions when in 1USR/USER mode.
Because I had -61 clear ("USR twice to lock"), the second time
I hit "left alpha" was actually "left user-alpha", because the 
second time, the keyboard was already in 1USR mode (because the 'S'
was missing from my user-keys definition).

In summary, if you define your own user-keys, and still want 
to be able to go into USER-lock, make sure you leave an 'S' in
the keys definition.

Doesn't the HP48 have a mem. cleanup feature that takes care of
fragmented memory? I believe the side effect of this is that sometimes
the calculator freezes up in the middle of something, and then continues
as if nothing happened.

I just got TRON 2+ and loaded it up.

But I don't have the docs.

I tried to play it, and it showed me two cycles on different screens. 
The left one was moving, and I controlled it with alpha, left-shift,
right-shift and 4.  But there seemed to be no point, because...

The other player just sat there.  I could change his direction by NXT,
down-arrow, right-arrow and 1/x, but he didn't move.  Nor could I figure
out how to make the HP play him.

I could be totally silly, and TRON 2+ is a two-HP48 game, to be played
by two people.  If so, can someone recommend a TRON game for single
people, who don't have friends w/48's?

And if not, can someone tell me how to get the computer to play?
