For reference, the advanced features of the HP-15C calculator are described in the May 1983 issue of Hewlett-Packard Journal magazine (page 25). A PDF of this issue can be found at:

Is there a link to the full pdf file?

emefff provided a link to the original site for the May 1983 issue of HP Journal magazine in post #21.
http://hparchive.com/Journals/HPJ-1983-05.pdf

At one time in the past this link for this one issue did not work so I had posted an alternate link to the same issue (post #4).
https://drive.google.com/file/d/1IrYfbFS...sp=sharing

The original hparchive link works now.

The link emefff posted doesn't work for me either. However replacing http with https does.

I'm not blocking http but something/someone is.

That depends on your browser/firewall settings. Not having https is very uncommon these days as the cert will cost you maybe 1-10$ per year.

Yes it does. And I control both. I know (for certain) that http isn't being blocked at my end. Perhaps my ISP is. I do know that http links won't work.

As you said very few sites are limited to http these days. Most are https.

PS: HTTPS mode only was disabled in my browser. I just enabled it.

The http link worked for me.

The https link did not work -- the browser was unable to obtain a secure connection.

The download was slightly over 10 MB.

Thanks.

Some browsers are set now to force https everywhere, which should automatically try https when given an http URL, but maybe some are misconfigured and just refuse to work with an http URL.

There's no excuse for not hosting on https now because certificates are free with LetsEncrypt (which I've been using for my sites since about 8 years ago).

Interestingly, for me the https site won't load because of an SSL error but the http site works fine.

Frankly, I think the 15C CE exists because it's basically just a variant of the current HP-12C. They did it because they could. A hypothetical 42S CE would presumably require too much engineering effort.

The best calculator is the one you actually use.

The 11C exists in a very sweet spot of a small, ergonomic package, and what it does, it does well. The same more or less applies to the 15C. The 42S is the all around more powerful machine, but if the subset of functionality you actually use is well-served by an 11C/15C, then the 42S is just more complicated. And there's one thing the 42S is not: It is not keystroke efficient. The LN/e^ switch aside, all the functions it shares with the 15C require at least as many keystrokes as on the 15C, and quite a number require more keystrokes, e.g. [f][FIX][2] vs. [SHIFT][DISP][FIX][2][ENTER].

And then there are the people who prefer the 32SII over the 42S, as evidenced by the fact that SwissMicros saw it fit to create the DM32. Comparing the 32S(II) and the 42S, it strikes me that the 32S is a tool ready for use and the 42S is a tool chest that you use to build the tool you need. Bear with me. The 32S provides all the functions many people will ever need, plus some limited programming (so as to not be inferior to its predecessor, the 11C), and the added equation support in the 32SII obviates the need for many programs. The 32SII is also more keystroke efficient. By contrast, the 42S has a somewhat more powerful program model, alpha support and, importantly, the memory that allows you to build custom programs. Using a 42S without writing your own programs seems like a waste.

These are all different sweet spots for different users.

Well Written.

It seems to be an issue lately. Newer browsers and/or policies?

FYI this site is https but requires TLS 1.3 to connect. TLS 1.2 won't work although it is still ok to my knowledge (TLS 1.0/1.1 are compromised).
