HP-45 Full Circle

[teenix]

Hi all,

My interest in HP calculators was re-kindled after seeing a HP-45 image on the web some time ago. I have no recollection of what happened to my original one many years ago, but young and silly and lots of moving around in those days.

I came across another one which was purchased in the same year that I purchased mine. In good condition, works, same serial number as documentation and the documents are in as new condition as well. So full circle, almost like when I purchased one back in the day :-)



cheers

Excellent!!

And of course, all answers are correct for this particular question...

Retirement is looking increasingly good once I find a country home that I like.

Do you have the grey plastic case these came in?

Hi Paul,

Yes, it came with the calculator. I haven't seen one of these before, I was sure my one came in a white cardboard box.

As it has an early serial: does it have the "old" register arithmetics mentioned here?

Congrats!

The 45 was also my first HP calculator, purchased when I was studying electronics in college. (I think I paid $450.00 in 1974....a fortune back then.)

I almost got the 35, but when I saw that the 45 could do polar<->rectangular conversions, I had to have one. (Try doing complex transmission line analysis problems with a Teledyne Post Versalog II slide rule!)

I've got dozens of other models now, but there's still a 45 on my desk for doing quick misc calculations. (And 3 more in storage as backups.)

It's still a great calculator.
Have fun.

Register = X - Register

The HP-45 was my first calculator. I still have it and it's working.

In the 1970ies I was in primary school, and if I was lucky and my father brought the HP-45 to home from work, I could use the calculator to do my maths homework. :-) Secretly, of course. :-)

Needless to say, I grew up with RPN and still don't understand those calculators with "=" and "(" ")" keys...
