For this week's MM theme, I again, thought of an old friend who's been with me for decades. We spent a lot of nights solving endless problems together and she always got me through each one of them. Things have changed a lot since but I decided to keep her all these years. I'm sure someone out there might still have a slide rule hiding somewhere.

Here is one of my potential Macro Monday captures taken today for the theme this week that is "Back in the Day".
This was my grandfather's calculator he used for work and for doing taxes. Can add, subtract and multiply.
Captured here at f/32, ISO 100 for 30 seconds.
The numbers I entered into the mechanical machine is the 'date' around when these were made.

Taken for 'Saturday Self Challenge': "Mechanical workings"

My contribution to Macro Mondays' challenge, "Pouch", on 14 Sep 2020. It's a well-used HP financial calculator, a relic from my pre-retirement past.

This model belonged to and was well used by my grandfather. Stylus may not be original but has been with the machine since at least the late 1940s. Still works perfectly.
For WAH who are visiting calculators. I couldn't decide so you get both with this for the daily shot and the other for the 123.

THEME: BACK IN THE DAY
I have no idea why I'm still hanging on to this calculator, my very first one. I know it has helped me a lot in passing exams that I could have not done with a slide rule!
an infinite field full of cabbage
as far as my eye could see, a field of green.
I found this field in Broek op Langedijk (West - Friesland) Noord-Holland
a warm memorie of a nice summer.
Thanks for the texture my friend: lenabem-anna
