HP 82204B Printer

Another tick box checked.   I purchased an HP 82240B Infrared Printer, which allow printouts from a lot of legendary HP calculators including (not an-all inclusive list) the 42S, 17B family, 32S family, 27S, 48 family, and the Swiss Micros DM41X and DM42.

The printer works on 4 AA batteries, I still have to buy an appropriate AC adapter for it.   

The printer works beautifully.   Check out the HP 82240B and some printouts using the HP 17BII+.

where a_i are all real coefficients.

New Videos: TI-65 Timer, TI-55 III Intro and Programming Demo

TI-65 Timer Demo 

A short demonstration of the timer feature on the Texas Instruments TI-65 calculator (from 1986).  Timer functions are rare on calculators.  (The only other non-graphing calculator I can think of that had a timer was the Hewlett Packard HP-45, and it was a hidden feature).

TI-55 III Intro and Demo

I recently purchased a TI-55 III programming calculator. This video presents a short demonstration of the calculator and a short program: the area of a circle.  The video is filmed with my phone.   My blog:  Eddie's Math and Calculator Blog:  edspi31415.blogspot.com

Math Videos and Update

Sample Slide

Over the next few weeks I am going to working several short math videos that I will post on YouTube.  When each video is completed, I will leave a link to that video on this blog.  

The videos are going to be pretty short covering various topics in mathematics.  

I hope you enjoyed the HP 15C programs posted over the last two weeks.  I plan to continue to post programs for various calculators this year. 

 I thank you for the comments and reviews.  Talk to you next time, and be safe everyone,

Eddie
