Comparing the HP 95LX Calculator to the HP 19Bu
The Calculator application on the HP 95LX was designed to approximate the
functionality of HP’s top-of-the-line business and financial calculator, the HP-
19BII. But because of the HP 95LX’s vastly greater memory, its much larger
display, and the availability of Lotus 1-2-3, the interface with the user is quite
different between the two machines.
Here’s a summary of the key differences between the two machines:

The 95LX’s larger display allows more detailed menus and variable specifica-
tion, shows up to 10 list items at a time instead of just one, and allows much
extensive plotting and graphing.
The 19B11 allows you to name, store, and recall SUM lists. The HP 95LX offers
no way to name, store or retrieve lists—only use a temporary, “current” list. In
many cases, it may suffice to enter the list of data into the built-in _ STRAT
template and then save the modified spreadsheet with a different name (see
page 67). Lists saved in this way can be used in most (but not all) of the same
ways that SUM lists are on the 19BiI.
There is no dedicated bond calculation menu on the HP 95LX as theres on the
HP 19B11, although you can create your own fairly easily, by creating a Solve
equation (see pages 58-59).
The HP 95LX has no menu dedicated to calendar arithmetic—the calculation
of the number of days between dates, the date a given numbers days into the
future, etc. However, the functions you need to do these calculations are
available to you if you write Solve equations (see page 60).
The Cash-Flow (CFLD) lists—and associated functions—used by the 19B1 to
work out the profitability of uneven cash-flows have been moved to their own
dedicated 1-2-3 spreadsheet (see pages 50-52).
The Statistical calculations made on SUM lists in the 19B1 are now accom-
plished by the 1-2-3 template, _STAT (see pages 67-69).
Solver has no depreciation functions (SOYD, DDB, etc.) but instead relies on
accessing these functions in Lotus 1-2-3 (see pages 61-62).
While the conversion feature on the HP 95LX is much easier to use than its
counterpart on the 19B11, it doesn’t have built-in conversions for temperatures
like the 19B1.
The Solver in the HP 95LX has a few functions that allow it to import data from
1-2-3 spreadsheet cells and to use that data in a Solve equation. Similarly, a
result can be exported to a 1-2-3 cell to be manipulated via Lotus @ functions.
See pages 63-66 for an example of these “communication” functions.
