It's even easier than that.  Just look on the back above the
battery compartment; it's permanently displayed in a little
window, whether the calculator is on or off--you can even tell
the serial number if the calculator has no batteries or has
suffered total electronics failure!

The problem with giving each calculator an individual
electronically retrievable serial number is that you have to make
one component that is much harder to mass-produce.  It's common
in software where your software duplication program can embed a
serial number in the easily writable software medium; it's much
harder to burn new ROMs for each calculator that contain the
serial number.  And if the calculator does go bits-up, you can't
get at that serial number any more.

Message-ID: <2a74760d.1477.2comp.sys.hp48.1@hpcvbbs.cv.hp.com>
Newsgroups: comp.sys.hp48

Regarding the use of 512k RAM cards intended for the 95LX in the 48SX...
I am not familiar with the 95LX but, the 48SX is limited by the
addressable memory it can access.  In other words, the 48SX can only
address memory using a 20 bit word.  This allows 512k of addressable
memory, which must include the 256k of ROM which leaves 256k of
addressable RAM (keep in mind that the 48SX addresses by nibbles instead
of bytes).

To get 288k of RAM on the 48SX, something called "bank switching" is used
that allows some ROM to be "hidden" or overlaid by RAM.  In order to use
a 512K RAM card, some form of bank switching must be used.  A 512K bank
switching RAM card is available from TDS (see EduCalc catalogue) for the
48SX.  I wouldn't think that the 512k RAM cark for the 95LX can work in
the 48SX.

The TDS bank switching card is like having four 128k cards in one.  The
bank switching is an electronic means of removing one 128k card an
replacing it with another.  Because of this, only one bank of 128k memory
is accessable at a time.

Disclaimer:  I am not knowledgeable enough to have figured this out on my
own.  The above is just what I have been able to gleen from the
conversations of those more informed than I.  I apologize for anything
that isn't exactly correct.

Hope this helps.

EDUCALC has brand new HP-16C`s for sale for $34.95, without manuals.

Having wanted one for years, I immediately ordered one when I found out.

It arrived a bit ago. There are some differences between it and my
original HP-15C, the logo is brushed metal on the 16C, and polished
on the 15C. There is an FCC class B notice on the 16C, but not on
my 15C, and the keycaps look like they were painted over keys from
an HP-11C or HP-15C. I cannot see enough to tell which.

The display is also slightly better on the 15C, the LCD segments are
bolder. 

But it is indeed an HP-16C, the ultimate bit twiddling device. Wish I
had had it when I wrote my assembler. The HP-42S is rather akward for
this sort of thing. 

I am at work, and do not have educalc's number available. Perhaps
someone who has it handy might post it?

Well, I still HAVE the 48... I still use it for the things the 32S II can't
do.  Also, a 32S II is probably a little less likely to be stolen than
a 48, nor would I feel quite so bad if I lost the 32S II.

It's interesting to note that HP's RPL manual says that one of the
distinguishing characteristics of a calculator vs. a computer is the
"instant on" feature. :-)

I probably should clarify the naming convention used for the Sparcom
cards. 

Reference cards-----contain data, tables, 'numbers', etc.

Application cards---contain formulas and 'solved problemns' ready to have
		    data plugged in for quick solution.

For a chemistry class, I'd suggest the application pack.

OK, how's this for a design concept: When first turned on, the machine
would be in "calculator mode" (no vars, no libs; that's programming,
that's computers!) and turn on real fast because it wouldn't have to
do a RAM checksum.  And if you want, you can use it, and turn it off
again (it'd turn off fast), still in "calculator mode".  But, if while
it's on, you press VAR or LIBRARY or USER etc., it would ONLY THEN
pause to do the checksum, and then be in "computer mode".  The fine
details of memory management in "calculator mode" would, of course, be
HP's headache, but be transparent to the user.

Sound like a plan?

Hi there,
  Well I was playing around with my calc the other day, and found out
this neat, but basically useless fact. Say I have the directory FONE in
my HOME dirctory. If I recall the directory to the stack ('FONE' RCL)
which as most know does not really recall it to the stack, but just
points to the memory location which holds the dir FONE. Anywyas the dir
is recalled to the stack. Now if I type 'FONE' PGDIR it transfers the
pointers and the directory object is on the stack, and is not just a
pointer to a memory location (same as performing a NEWOB). 
  Well what I wasn't expecting is if you go back to the point where the
dir on the stack points to the mem location, and the directory still
exists, but take a different approach. What you next do is go into the
directory and do a CLVAR (clears all vars in a directory). This thime
instead of the HP moving the object to the stack, after the HP has
cleared all vars the stack reads 
1:   DIR END

Oh well I thought it was neat. Hope I didn't waste too much bandwidth!
