It is HP-11C in stead of HP=11C..... sorry for this typo error....
But am the only one (apart from 6A3sUMMER) using a slide rule in the very very past?? 😕

I used a slip stick as I grinded my way thru the system.
Joining HP in Toronto in 1965 I managed to try several generations of the HP Calculators, beginning with the HP 35.
Including the HP 80, the financial calculator with LED display.
By the middle 70s I was carrying an HP 67, I still have it & it still runs. I was very quickly converted to thinking in terms of RPN calculations.
RPN solves problems the same way we do with pencil, paper & slide Rule, from the inside out.
A few years ago I bought an HP 35s. The computing power is quite a bit beyond the HP 67. But the display is the sh*tz.
Both LEDs & small batteries have come a long way since Hewlett & his shirt pocket HP 35.
The 35s could have been a lot more usable with a better display.
The small collection of HP goes on, I've two 71Bs, a 75 all work on the HPIL, HP Interface Loop The commands are all in Basic.
Also a disc drive for the system, tape reader & interface board to a Windows Computer. Most not used now. The Slide Rule does
not hookup to the HPIL!😀
