6S review not too unfavourable: "Just for grins, I ordered a new-in-blister-pack HP 6S Solar. I figured it would be fun to experiment with HP's cheapest calculator. From the Museum description, I expected a minimal-feature machine. I was surprised to find a calculator fully worth the USD $8 I paid (shipping included.)"  from John Shelton https://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv015.cgi?read=76976

Take care Jackie!  

from EdS :  4:13 PM

Eddie you don't seem to have reviewed the 6S

from Edward Shore :  4:13 PM

You are correct, Ed. I have never had the HP 6S; only read about it.  

from EdS :  4:14 PM

It seems to me maligned. But I think the same about the 35s.

from Edward Shore :  4:17 PM

I can see that, Ed. The big knocks against the 35S seem to be: the bugs, lack of Polar/Rect conversions

from Godwin Stewart :  4:18 PM

Not to mention only 26 labels...

from Edward Shore :  4:19 PM

Thankfully, we can use step addresses within those 26 labels. Also, it would have been great if we could have transferred 35S programs to and from the computer.

from Edward Shore :  4:20 PM

The HP 71B roms are hard to find!

from Godwin Stewart :  4:21 PM

Ed, that's true, but the renumbering of GTO destinations is buggy when you insert/delete steps, so it makes using step addresses (the only option available) very unreliable.

from EdS :  4:23 PM

(For me, these maligned machines are good, just not as good as we'd like them to be.)

from Edward Shore :  4:26 PM

Exactly, Ed.  

from Edward Shore :  4:27 PM

The lack ability to have multicharacter labels or prgram names hurts the 35S (and 33S).  

from EdS :  4:28 PM

My biggest gripe with the 35s is that hex mode isn't nearly as easy to use as I'd like.

from Edward Shore :  4:28 PM

I totally forgot that the 35S has base conversions.

from David Hayden :  4:29 PM

It's far from perfect, but if you the program name as an equation in the first step of a program, then at least you can tell what's what by going into program mode and going to the label.

from Edward Shore :  4:30 PM

Agree, David.

from Edward Shore :  4:31 PM

Was the 35S the last RPN calculator before Swiss Micros?  

from David Hayden :  4:32 PM

The problem with step addressing is that it's only practical when you're branching back to existing steps. If you need to branch forward, then what do you do?

from David Hayden :  4:34 PM

I tried a technique that would have been handy if it worked: program with the 26 labels, then delete the labels. In theory, the GTO and XEQs should go to the statement after the deleted label. But it doesn't work. The code that adjusts addresses doesn't work when going between alpha labels.

from Edward Shore :  4:38 PM

Indirect addressing labels only go to the first step on 35S; another missed opportunity. (OT: I miss my 27S)

from EdS :  4:39 PM

> Was the 35S the last RPN calculator before Swiss Micros?  

The 30b comes after, I think.

from David Hayden :  4:39 PM

Good point Eddie.
