Early to mid 70's .. but I may be wrong about the model #. I do recall that is was designated as a "student calculator".

Don't hold me to the exact particulars.

--------------------------------------------- My first job out of school was in the engineering dept which included the estimating group.

Everybody in the estimating group had a comptometer on his desk.

If they had been Orientals, maybe they would have been an abacus instead.

My first was an HP45--marvelous when it worked. Four hundred bucks and it wasn't reliable. Seems downright primitive today.

In 1970 I bought with a loan app - a $600 calculator from a business supply company. It was a 12 digit Nixie tube four-banger with memory. It saved the beloved and I when doing grades. A few more years later I had a machine language computer.

I did logs on that 4 banger - trig sin and cos and tan. There were some very creative guys learning tricks and approximations and small formulas that one could get good numbers.

The company was Cannon. I scrapped out the machine in about 1995 or so. It had a bad supply - HV likely leaky and the controller wasn't up to speed.

Several years after the first TI and HP came on the scene - and we both died. $150 for a full blown ? - I think we still owned about that much on the Nixie box. TI's SR-50 ... Been a TI and HP guy since. Went to HP in 85 and back to TI in 2008.

I had a small circular slide rule, Dad had a tubular slide rule. We both still have slide rules in our desks and use them. Faster than getting out the banger and entering the number.

Long calc's or complex ones bring out the box - one or the other.

Nope ... mid 70's.

I held off buying a pocket calculator until I could get one that was both programmable and affordable.

I ended up buying an HP-25. I still have it stored away somewhere, and the last time I powered it up, it still ran.

I used that until 1980 when I got a Radio Shack TRS-80 Pocket Computer that could run (sorta) BASIC programs, read/write to a cassette drive, and print on a cash register size tape. It's here on my desk needing new batteries (and a new ribbon for the printer).

Just a comment but I picked up a piece of software a while back called "The Mathematical Explorer" for about a hundred bucks. Turned out to be the Mathematica 6 core with a couple of features turned off and without some of the add-on packages. They've discontinued that now and have a full-featured version sold for non-commercial use for 400 bucks or so. If you happen to find the older one though for the low price it's well worth getting if you ever have to do any kind of serious computation.
