Yeah. I had an TI SR-10 that was much faster than a slide rule. I always brought the slide rule to an exam in case the TI battery conked out during the test. It did a couple of times and I discovered how quickly one's slide rule skills can get rusty.

oh. HP in the 70? you had already big money in the family ;-)
That was NOT easy for me to get an HP41CV in 1983. That was expensive. But unbelievable good fun.

I never liked that stupid rippin' logic (RPN). Oddly I found an HP with AOS and got it because for years friends told me the key quality was unprecedented. Tis true, how many buttons would break on a TI calculator. I still have the HP my daughter used it in high school. Never use it these days, either just my phone or a desktop computer, and usually Excel formulas or MATLAB.

Stupid RPN?
I have another view: RPN makes thinking in sequencing and stacking before you click the keys. A kind of brain jogging.
However by these days, all sequences are stored in the new expensive calculators. by recalling the sequence and modifying it, error can be corrected.
For me, the best calculator would be
- RPN (and switch possible to the mode arithmetic)
- Stack of 4 (X Y Z T) and adjustable (till 1000) according user wish
- Storage of the last 23 operations (and recall possible)

My whole life I chose the 'loosing' side (RPN, Beta, Linux) and love it.
When my HP35 gave up its soul decades ago because of coffee overdoses, I never buy another expensive one again.

I found the HP-15C simulator to be rather good; multi-platform and written in Tcl.
