That's great, but...(the 35s)



#4

We're like a group of good professors, always pushing their students (that's great, but did you consider THIS case??) :)

I'm greatly looking forward to the new 35s. Here's one detail that I hope is addressed:

I'd hope (in addition to the requisite matrix support, and other oft mentioned capabilities) for the 35s to not carry over the lingering 'operation' trait that the 33s has. What I'm referring to is the response to a keypress where the operation name is shown on the screen (x^2 for example) for the duration of the time the key is depressed. I've always been annoyed by that on the 33s.

How does the 41C act compared to the 33S?

I have never found the 41C operation to be an irritation. In fact, I almost never notice it.

In fact, with USER mode on the 41, it is a very useful, (almost required) feature that I rely on. With my 33s, it would be useful if it had the same implimentation that the 41 does in that if the keypress is held long enough, the command is canceled.

#7

On my 41CX, the display responce is just slow enough that you don't see the function preview when the key is held for what I would consider a "normal" duration. Not so with the 33S and it's faster display.

IMHO, that's the difference (in addition to the 41's null option).

Best regards, Hal

In fact, with the 41, (and others,) the function will cancel if you hold it long enough. That's super useful if you sometimes make errors. The 33S previews, but won't cancel. So you get to sit there like an idiot, with disaster staring you in the face in the form of a function that will kill all the work you did today, not daring to lift your finger, but having to use it for something else, like dialing the phone for example.

Of course, I don't make errors, but my evil twin does. He just loves this wonderful preview capability on the 41.

Sorry to hear that...

I use my own 'undo' routine. When I err, it launches with fairly little delay (although it often generates curse words). Some of my jealous co-workers claim that my 'undo' routine is nothing more than me re-entering the arguments a second time, but I usually don't let that bother me. ;)

Hi, ECL --

In fact, I mentioned that one in 2004. From

http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv014.cgi?read=62029#62029:

"The display instantly changes to name of function when a key is pressed, instead of after a time delay when the key is held down, as on the 32S, 32SII, and 42S. It is disconcerting to watch the display flash each time an operation is performed."

The "null" feature of the HP-41 and HP-42S (also in the HP-15C matrix navigation) that others mention in this thread would also be desirable.

The 35s is obviously a retooled 33s, with some of the major shortcomings addressed (appearance, data storage). So, when in doubt about what behavior to expect, I'd look to the 33s and assume something like that, until we actually have the 35s in hand.

What about those "800+" registers? Two-alpha (alpha-alpha: "AA", "AB", "AC" ... "ZZ") naming would allow for 26*26 or almost 700 separately addressable registers. Alpha-alphanumeric ("AA", "AB", ... "AZ", "A0", "A1", ... "A9") would allow 26*36, or over 900 addresses. I wonder where "800+" comes from?


#14

I think Valentin Albillo came up with a senerio that works for the 800+ registers. Of course we'll not know for sure unless one of the HP folks reading this forum responds or we finally get or grubby little fingers on one...

Thanks for that. (I've been away, and only just now found out about the 35s -- I haven't had time to read through everyone's observations.)

I've been able to get past the 33s' looks and limitations, and have enjoyed it immensely. I certainly am looking forward to getting 'hold of my 35s!

I do to! I have peaceably lived with the HP33s's more embarrassing bugs, like the errors involved when cos and tan take arguments close to 90 degrees. I am looking forward to the increased register number. But I am especially hoping that the restricted number of program labels is rectified, perhaps with an alphanumeric labelling system akin to how the registers are directly addressed.

If the 35s uses 33s processor electronics, or better, then I am particularly looking forward to its speed. I have a number of special function routines that basically iterate a series or continued fraction to convergence. They are agonizingly slow on the otherwise revered 15C, a bit faster on the 11C, a bit faster still on the 41CX, somewhat quicker on the 42S, but quite peppy on the 33S. I really hope for more labels and registers so I can easily port some of my favourite 41C programs and watch them run much faster.

Indeed, despite its many flaws, it is the speed of the otherwise maligned 33s that makes the revered 15C, for example, seem embarrassingly archaic and irrelevant in comparison. If the 35s extends the strengths of 33s and incorporates the improved quality observed in the 50G, then we could have a pretty darn good RPN programmable scientific.

Both the 33s and 35s data sheets specify a SPLB31A processor, with many other similarities (batteries, display, etc.) I'm sure it's a 33s with a new skin and updated firmware.

  • The 800+ storage registers might be addressed like this:
          Register 00 to Register 99  =  100 registers
    Register A to Register Z = 26 registers
    Register AA to Register ZZ = 676 registers
    Register (i) and (j) = 2 registers
    ----------------
    804 registers



The above may be very close to how it will be done, but the fact that the numeric keys 1 through 9 also have letters R through Z, and 0 has (i) on it, will complicate things a bit. For example, how will the calculator know the difference between RCL 89 and RCL ST? My preference might be to dispense with the letter designations altogether. Just give it 3 digit memory addressing, which would be typed in fully for three digit numbers, such as RCL 123. To access registers 1 through 99, you’d terminate with ENTER, e.g. RCL 1 ENTER recalls register 1, RCL 11 ENTER recalls register 11, etc. That paradigm would yield 999 registers plus (i) and (j) for a total of 1001, so I doubt that is correct either.

#19

I see the "(i)" and "(j)" functions, but no "i" or "j". (Yes, there's an "i" key, presumably for imaginary number entry, but no obvious way to store or retrieve directly the i & j registers.)

There must be some new contextual method of distinguishing "STO i" from "STO (i)".

Yeah, I'm interested . . .
