(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.

[*] 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...)

>19BII menu 95LX notes > >FIN TVM AMRT TABLE through 1-2-3 application >Craig A. Finseth fin@unet.umn.edu [CAF13] It was a little ambiguous from your table, so I wanted to point out that the TVM and Amortization capability is available in the Calculator application. If you want to create an amortization table, there is an easy way to direct the amortization information into a 1-2-3 spreadsheet. From your table, it could be assumed that TVM & AMRT are accessible only through 1-2-3, which is NOT the case. --Susan

The calculator application can generate the TVM amortization and send the table to EITHER the printer or to 1-2-3. Also, the HP 95LX calculator has an added "adjust" menu that makes it much easier to calculate adjustable rate mortgages. Cash flows are available as a 1-2-3 template, as you mention. Bonds, however, are NOT included in the product, either as a part of the calculator or as a 1-2-3 template. There are (expensive) add-ins available for 1-2-3 that handle bond calculations, but HP has not tested these and does not support them. Depreciation is not available as a 1-2-3 template, but 1-2-3 does have @ functions for doing depreciation, so it's pretty easy to set it up. >BUS CURRX different implementation > UNITS different implementation, missing temperature units The HP 95LX has a user-definable screen of currency conversions, where the user supplies/edits the currency names and exchange rates. This could, of course, be used for setting up any type of conversion that is a simple linear relationship, but not ones with an additive component (such as temperature). >SUM 1 unnamed list, otherwise through 1-2-3 application The HP 95LX list is limited to a maximum of 100 entries, whereas the 19BII was limited by available memory, a maximum probably in the range of 700. >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) > SINH COSH TANH --not available-- > ASINH ACOSH ATANH --not available-- > FLOW SIZEC #T --not available-- Here, it's not clear what you mean by the "1 unnamed sum list". The SOLVE portion of the HP 95LX calculator allows you to have as many different files of equations as you wish. Each file can contain many more equations than the 19B could hold. Other additions on the HP 95LX include: Backsolving of 1-2-3 spreadsheets. STO to spreadsheet cells, force re-calc, and RCL from spreadsheet cells. Equation graphing functions (similar, but not identical, to the HP 48's). Find function (for finding an equation; remember, the HP 95LX can support LONG lists of equations). Typing aides when entering/editing expressions. >TEXT MEMO and PHONE applications > >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...) > >Craig A. Finseth fin@unet.umn.edu [CAF13] Other than that, a pretty good comparison of basic functions, Craig. And the reason why the 19 had hyperbolics: ?because they were there?...:-).

You are correct: my summary was ambiguous. I meant that the TABLE menu under th AMRT menu under the TVM menu was implemented through a 1-2-3 application. Craig

For the most part, I was avoiding mentioning things that the 95 did that the 19 does not. >Cash flows are available as a 1-2-3 template, as you mention.

I stand corrected. I can always use my 12C to do these (:-). >>SOLVE (again, you get 1 unnamed sum list, otherwise through 1-2-3 application) >Here, it's not clear what you mean by the "1 unnamed sum list". The SOLVE >portion of the HP 95LX calculator allows you to have as many different files ... The reference was to the solver functions that use sum lists. The 95 doesn't do CFLO type lists at all.
