I've dropped my HP48 from about 1.3m with the EQ Lib card while in
its carrying case. It made my heart skip a beat but otherwise the
48sx and owner were both fine. :-)
More recently, a friend had his 48sx drop sans case on a carpetted
floor from ~.8m and the expansion slot cover went flying, the card also
went airborne but otherwise no permanent damage resulted. I was actually
comforted by the flying debris because the cards appear to be even
more sturdy than the calc and transferring energy to those things
is probably sound disaster engineering. Sorta like my fm radio the
way the belt clip, battery cover, and batteries fly about every time
I drop it.

I'm halfway there..I have the hardware built, but not the software.

Here's what I got so far:
 I can send full RS-232 from the calculator..just enter a string and run a
small IMC. I have been effectively making disassembly listings to aid me in
trying to solve the second part (receiving). Basically, the IR LED has been
extended out to a prototype board for interfacing to a DB-25. All that is
needed is that other than getting the timing correct, invert everything you
send since RS-232 is normally held HIGH instead of low and I didn't want to
unnecessarily drain calculator power.
 There is a second connection which makes a fake keystroke via a similar
arrangement that is already built and functional. The key it fakes is the
"nonexistant" key beside the ENTER key.
 Now, so far, I have figured out that there are 20 lines going to/from the
keyboard matrix. These lines are polled by setting bits via the CPU port
(OUT function) and reading the corresponding CPU input port (IN function).
Somehow, the interrupt is also tied to this mess.
 I tried disassembling the ROMs in the keyboard test routine for clues. I
found out about the polling mechanism from there, but I was not able to
figure out which OUT lines are controlled and in what way since some of the
memory mapped I/O on the 2 I/O chips seems to be involved also. I also
believe (not positive) from disassemblies of the beeper routine that bit
11? controls the beeper on the output port (appears to generate tones by
pulse width modulating the piezo-electric element).
 But I haven't been able to figure out how the keyboard works yet at all,
so developing a reasonably fast (1200-2400bps) input routine is at a
standstill, and just using RPL and the KEY function is VERY slow, since
about 500ms of a "keystroke" are needed for KEY to recognize a stroke.
 Does anybody know any of the following:
 How does the interrupt routine work in the case of the HP28S version 2BB?
 Where is this routine (or even the vector if there is one) located in
memory?
 How are the 12 bits of the output and 16 bits of the input port mapped to
the hardware?
 The interface I have built required opening the calculator (of course..). I
connected it via a 4 pin 100 mil spacing SIP (it turns out that only 3 pins
are actually needed). The circuit itself is driven by a 9 volt battery and
requires 2 optocouplers and 2 op amps. I will post the complete details,
including the circuit, programs, conversion, etc., when I can piece together
a usable input routine.
 If you are working on this same circuit or need any additional information,
you can mail me.

Yes, the TI-85 is MUCH more useable with respect to solutions of polynomials
or simultaneous equations.  You can store any of the results in variables
of your choice.  I had a 68 before the 85 and I agree, the ability to store
results of these two operations was severely lacking.  Fortunately, I don't
have to worry about that now.

The cards in the hp48 insert into one of two slots inside the case, behind
a cover, so they would never fall all the way out of the machine; you cannot
tell they are there since they are inside, except for the added weight.
As for if they fall out? Well, they can tend to move if you were to
drop the thing such that it lands along the top edge of the unit
(since this is the way they went in). I have had a 128k memory card
merged with internal memory, pulled out accidentily by me (I thought
I was grabbing the other card; how embarassing) and I thought I blew
away the file system. But the hp simply said on the screen
"please re-insert ram card". I did so, and it picked up where it
left off. Now THAT's robust software!

I am thinking of getting myself a Psion 3.  If I do, I would like
to be able to transfer files to and from a Unix box.  From what I
have read, the serial cable and software for the 3 is meant for
an MS-DOS machine, which is not exactly the most convenient
machine to use (for me).

Can one transfer (easily) between a Psion 3 and a unix box?  (a
Sun ELC, in particular, but this shouldn't matter...)

I seem to remember reading that HP tested the 48 by dropping it from ~6 feet

I believe EDUCALC has them, and for HP stuff, they are pretty cheap.
I think the price is about $279 or so. EDUCALCs number is 1-800-677-7001.

Indeed, HP now makes algebraic calculators. TI on the other hand has
gone off the deep end with Algebraic. I played around with a TI-68 for
a bit, but it is difficult to use even for a TI, due to it's 'enhanced'
AOS (Algebraic Operating System). It has some nice features, like the
ability to solve 5th order polynomials, but you have to write down the
answers to use them in something else. They seem to have backpedaled 
a bit with the TI-85, but I'm not sure if it is useable.

When my HP-15C was crushed in the Loma Prieta (a full bookcase fell on
top of my monitor, which was saved by my HP-15C <sigh>), I wanted to
replace it. All they had at the time was the HP-28C and the new HP-27C.
I could afford the HP-27C, so I bought it. It is algebraic, and usable.
The equation solver is the best I have used, but there was that equals
key. Eventually I got an HP-42S, which I use today. And I even replaced
the HP-15C when EDUCALC got some in. 

I'd say AOS is about as unusable as you can get for anything but copying
straight out of a book. RPN with the 4 level stack is great for problem
solving and fooling around with the numbers. As for the HP-48SX, with
a full stack, I wonder. Anybody care to respond?

Tote-A-Lap (which advertises in BYTE, but not in C.S.) has the best prices
on memory upgrades and SRAM and FLASH cards.  So far I've bougnt a 2M

two 1M SRAMcards, and have been completely satisfied with all of these
items.

Their service was fast, their telephone people were courteous, the items
ordered were shipped as advertised and still work, and they're the cheapest.

Only trouble is, you have to look in the advertisers' index in BYTE because
I don't have their telephone number handy.

	Well, wouldn't the LCD be easier to break if you move the TI-85's
case cover to it's back?
	I thought that TI's are pretty rough against such accidents like
droping them on group.  Especially those TI-30 to 35 series since they
are light, small, and flat. I saw people banging them around before and
cause no problems.... While I'd say Casio is pretty fragil.  I am talking
about those Casio Scientifc caluculators here.  I once had a a Casio-115D,
which does a lot of neat thing even the manuplation of imaginary #'s.
However, once I putted it in my backpack with a game catridge asode of it.
After half hour, I discoverd that the whole LCD screen broke.  (I probabely 
dropped my backpack a little fast when I got home)  Anyway, does anyone
know if TI-85 did a similar "test-dropping exp"?  It would be nice to know
that at least your $100 calculator does have a little protection after all.
	Also, here is a key to solving this "TI backcover fly!" problem.
Go find a piece of really thick paper (like the paper boxes), cut it so
that it's about half inch long and as wide as the slit of Ti's backcover
hook.  Try to fold the paper if it's not as thick as the slit.  Insert
this tap in the slit (So that the hook has no room to squeeze back and
the backcover won't be open then).  You should have about 3-4 mm left
outside from the slit (Hey, back to the metric system :)fold it up, and
insert it it to the little slit above the main slit (sounds really 
confusing, I got use a CAT to show you exact what I mean, but use
your imgination)  After that, push the paper tap a little to make
sure it's flat so that when you put the calculator on a flat surface, it
won't "rocking roll".  Finally, go get a short stripe of masking tape
and tape it on the paper tap, so it will be staying there for a while....
This is not a good solution, but at least it works.  And it's simple
too!  (though I haven't "test drop" my TI yet to see the result)....
		And that is all, folks....

Well, it's pretty unlikely -- the cards don't stick out. Perhaps
your hp48 w/ a card inside is more likely to have problems after
multiple drops than one w/o a card, but the cards are pretty sturdy.
Here's a picture of the back of the 48:

with nearly all keys. The keyboard was terrible. Lateron I've aquired
the TI 30 Galaxy. The keyboard has been working perfectly all the time and
it still works today.

Now I have the HP28S as well. I like it's keys. The whole keyboard works
nice except of one key: sometimes I have to press it a little harder
in order to perform a function.

Repeat items

-  Timed and Untimed repeat items are stored in exactly
   the same way as normal timed and untimed items, except
   that they have a DayNumber of 65534 (fffe Hex).

-  The specific repeat details are stored at the end of
   the Text field and have the following format:

   Byte:      Type
   Byte:      Interval
   Integer:   StartDayNumber
   Integer:   EndDayNumber

-  The Type field can take the following values:

   Repeat Yearly                = 0
   Repeat Monthly By Date       = 1
   Repeat Monthly By Day        = 2
   Repeat Weekly                = 3
   Repeat Daily                 = 4
   Repeat Workdays              = 5


-  The StartDayNumber and EndDayNumber are stored as the
   number of days since 1/1/1900 (=day 0).

-  Setting the EndDayNumber field to zero will mean the
   item will repeat forever.
