Does the HP-35S need a 'guide for dummies' how-to guide?

[TASP]

My first exposure to HP calculators was the HP45. An upperclassman had one and it was quite the topic of discussion.

I had a TI-SR10 (IIRC) and a Commodore SR1400 (IIRC). At some point after it came out, I decided the HP-25 was at the right price point for me to get one. I still have it and it works. I've had a couple HP41s, and I am astonished at how 'primitive' the HP25 feels now, even though when I got it I was totally amazed. Since the 25 was programmable, it was clearly better than the 45. At $795, the 65 was just unapproachably expensive. I never knew anyone who had one, and to my knowledge, even to this day, I've never held one in my hands.

I consider an HP55, and thought it was really potent, but it was around 2X the price of the 25, so all I could do was look at the brochure and dream. The HP55 timer was a VERY appealing feature. When the Time Module came out for the 41 series, I was a happy camper; that was WAY better than a 55.
