Re: I think I can help... Message #9 Posted by Ellis Easley on 2 Sept 2002, 1:30 p.m., in response to message #8 by Vieira, Luiz C. (Brazil)
Yes,I think those will help because the BA55 and 54 should be closer to my model than the BA Solar. Mine is just called TI Business Analyst, it is the same family as the TI57. Here is the datamath.org page:

On this page at TI, you can download a QRG for a BA-35 Solar and a complete manual for a BA Solar, which I think TI must have supplied with the BA-35 Solar. This page is for the English version and the only other choice is French. The BA Solar manual has the notes on page viii "Special Note to BA-II Owners" which helped me understand my machine better, especially the section called "Enhancements" at the bottom of the page:

The TI website also has manuals for the BAII Plus and the BA Real Estate. I downloaded the BAII Plus manual and it appears to be much more advanced than my calculator. Here is the TI page where you can choose a manual to download:

You could be right about the "polarity" of money - here are some notes I made from the BA Solar manual (I don't think they apply completely to my BA because for annuities, it requires one of PV or FV to be 0):
PMT=0 : Compound Interest
PMT<>0 : Annuity
PMT + (discounted backward) : mortgages, loans, leases, bonds - have PV, FV may be 0 - PV, PMT flow opposite directions
PMT - (compounded forward) : savings - have FV, PV may be 0 - FV, PMT flow opposite directions
I wonder if the two wire TI printer you mentioned is the PC200? I have one that I got in a package with the TI66 from a closeout catalog. (Datamath.org indicates the PC200 was only used with the BA55 and the TI66.) The TI66 is the LCD version of the 58/59: it has a little more memory than the 58, 512 steps (the 58 had 480 and the 59 had 960) but like the 58, the 66 has no card reader. BTW, there is the 58 and the 58C, both have 480 steps but the C has constant memory. I wonder what kind of courage it takes to type in a 480 line program knowing your batteries could go out at any time? These calculators allow you to partition memory between program and registers (8 steps per register), and as has been pointed out here, some small programs need a lot of storage space.
