(I would like to apologize for interfering with the "how to split the
group" discussion.)

Differences betweeen the HP-19BII and the calculator mode of the HP-95LX.

Before I purchased my 95, one of the questions that I had was "is the
calculator a *real* 19BII?"  The answer is "yes, mostly."  This note
will itemize what is meant by "mostly."

Simple differences in the menu organization, and obvious physical
differences (keyboard, display, etc.) will not be mentioned.  This
list concetrates on functionality.

19BII menu		95LX notes

DISP	FIX All		Menu Options Format, adds Sci and Eng
	. ,		SETUP application

MODES	D/R		Menu Options
	BEEP		SETUP application
	PRNTR		SETUP application, only serial printers are supported
	INTL		SETUP application
	DEMO		--not available--
	ALG RPN		Menu Options

PRINTER	DISPL		Menu Print Stack
	LIST		1-2-3 application
	REGS		Menu Print Data, Menu Print Registers

FIN	TVM AMRT TABLE	through 1-2-3 application
	CFLO		1-2-3 application
	BOND		1-2-3 application
	DEPRC		1-2-3 application

BUS	CURRX		different implementation
	UNITS		different implementation, missing temperature units

SUM			1 unnamed list, otherwise through 1-2-3 application

TIME	CALC		--not available--[*]
	APPT		APPT application
	ADJST		SETUP application
	SET		SETUP application

SOLVE (again, you get 1 unnamed sum list, otherwise through 1-2-3 application)

	ASINH ACOSH ATANH --not available--
	FLOW SIZEC #T	--not available--

TEXT			MEMO and PHONE applications


[*] The TIME CALC functions can be written using the solver as:

   {0=DDAYS(DATE1,DATE2,if(s(DAYS),1,if(s(x360D),3,2)))-if(s(DAYS),DAYS,
   if(s(x360D),x360D,x365D))+0*TODAY*l(TODAY,CDATE)}

Limits on use: (1) when solving for DATE1 or DATE2, the actual
calendar is always used and (2) you have to solve for something once
before TODAY is initialized.


In conclusion, the only material differences are:

	cash flows
	bond
	depreciation
	hyperbolics (yes, I wondered too.  wondered, that is, why the
		     19B and 19BII had these...)
