Calculators I actually use.
Hi everyone
I was looking at my collection and there’s a couple I don’t use at all. So decided to make a list of ones that I actually use for work, etc.… 1970’s thru 1980’s: HP-45, HP-11C, Jeppeson CR-2 Flt Computer (Circular Slide Rule). Late 80’s thru early 90’s: HP-11C, HP-42 Mid 90’s thru 2000: HP-11C, Military E6B Home Office: HP-42 Garage Office, HP-28S, HP-35S On my person : (Depending on the day) HP-11C, PX11C/15C, Hemmi 32 Slide Rule, and now the DM15C Credit Card Calc. Calc I use the least HP-18C Calc used most for fun: HP-41CV Wife uses a HP-12C. (she was at work and the big boss from corporate walked by and said “Wow you use a HP”, upped here creds with the staff. For the ones that are just in my collection I need to start rotating them or at least pull the batteries. Randy |

Hello!

The only one I really use is the smartphone app shown below that can add and subtract times (and nothing else). I only need that at work, so I don't make stupid mistakes when filling in logbooks. I would prefer to have it in hardware, but unfortunately nothing like it was ever made. Of the other 1,000 calculators, I don't really us any, apart from occasionally trying one out, but this is all. What a waste of keys and displays! Regards Max |

RE: Calculators I actually use.
Almost all of my machines are in storage.
Most of my mathematical work is done on spreadsheets these days, not calculators. I do keep a small assortment of restored machines on hand in case I have the urge to use one or write a program. But that falls more under 'recreation' than anything else. -J |
