Hello Valentin: I'm curious about the Sharp calculators you have. How do they compare to HP calculators? What models do you consider the better ones? Thanks, Nick

Some of my HP calculators are pictured here: http://www.hpcalculators.net but many others aren't, I'm still too busy (or too lazy :-) to add more pictures. However the best I have is the HP-9100A, I like sometime to switch it on and play "Moon rocket lander", the software had been loaded from magnetic card more than one year ago and is forever present in the magnetic core memory (a true continuous memory!)

                  
SHARP vs. HP comparisons [LONG]

Hi, Nick:

Nick posted:

"I'm curious about the Sharp calculators you have. How do they compare to HP calculators?"

All the models I have but one are what they used to call "pocket computers" as opposed to "pocket calculators". As such, they usually are much faster than HP's, have much larger RAM, are programmable in an advanced version of BASIC, have full I/O capabilities (even the smallest models), and boast larger, dot-matrix, alphanumeric and graphics displays, sometimes 2-line or 4-line, and support keyboard redefinition and assignment of program entry points and arbitrary definitions or sequences of characters to keys.

All can be programmed in machine language by using PEEK, POKE and CALL, all have 12-digit accuracy, all can recall the executed command line for re-executing it or edition at the touch of a key, all can insert the last result in the middle of a new computation, or continue an already executed expression.

IMHO, the main operational difference between "pocket computers" and "pocket calculators" at this level of price and size, is, briefly, that "pocket calculators" have very extensive preprogrammed capabilities but essentially poor programming capabilities (small RAM, slow, low-level language) while "pocket computers" have larger RAM, faster speed and high-level language, but less preprogrammed features, *unless* they are specialized models, which effectively provide the best of both worlds.

These specialized SHARP models, akin to the Voyager series, have been fine-tuned for such fields as business & finance (a la HP-12C), statistics, matrix operations (a la HP-15C), CASL and statistics, and computer science (a la HP-16C), among other applications and fields. They do have the same advanced BASIC with the same base capabilities, but extended with their specialized functions set (say, IRR computation in the finance model), fully integrated with the BASIC language so you can use them in your own programs.

Some models also feature a separate "calculator mode", where you can use the machine as a typical algebraic calculator, albeit with a larger function set (hyperbolic, statistics, matrix operations).

Considering all the facts, it's difficult to see why HP models are usually considered 'the very best'. Take, for instance, the comparison between two financial models, the HP-12C and the SHARP PC-1421 (aka EL-5510 in the US).

  • Both are more or less the same size, with the 1421 being slightly longer (6.7" vs. 5.1") but less wide (2.8" vs. 3.1" ) and also 50% thinner (0.4" vs. 0.6"), both weight more or less the same (5 oz. vs. 4 oz.), but the 1421 has a shiny, full metallic body with a slight golden tint.

  • The 1421 has a fully alphanumeric, dot-matrix, 16-char LCD display, vs. the HP-12C's numeric-only, 12-char, segmented LCD.

  • The HP-12C's keyboard is better, but that doesn't mean the 1421's is bad, quite on the contrary it's perfectly usable and long-term reliable as well.

  • The SHARP-1421 is programmable in an advanced version of BASIC, including long variable names, two-dimensional arrays, string arrays, I/O commands including printing and serial I/O, multi-statement lines, easy program editing with insertion, deletion, and editing of whole lines, and can use up to 4 Kb for programs and data.

    Further, all BASIC commands and statements are internally tokenized, so that "INPUT", for instance, takes only 1 byte (not 5), which helps save RAM and improves speed. All financial statements and functions can be used in BASIC programs. Besides, it can be programmed in machine language if need be, or desired, or just for fun, without any add-ins. You can enter several programs at once and assing their entry points to specific shifted keys on the keyboard for immediate execution.

    On the other hand, the HP-12C is programmable in RPN keystroke language, no insertion or deletion of lines, no advanced programming features at all, not even subroutines (!). Programs can be 99 bytes long, and that's all. Machine language programming is out of the question, and not only can't you assign programs to keys, but it doesn't even have labels to mark their entry points.

  • The SHARP-1421 is fully alphanumeric, and has a full QWERTY keyboard, including lowercase characters. The HP-12C has no alphanumerics whatsoever, so that even program steps have to be displayed as numeric keycodes, and neither inputs nor results can be labeled at all.

  • The SHARP-1421 has complete I/O capabilities, can be connected to a printer, to a mini-tape recorder, and to arbitrary serial I/O devices, with full support from dedicated BASIC commands. The HP-12C has no I/O whatsoever, not even printing, which some business users could probably have a use for.

  • The SHARP-1421 is *much* faster than the HP-12C, more than 20 times faster. Like the HP-12C it also has continuous memory, and like the HP-12C, it uses standard batteries (CR-2032) which last very long.

Considering all these facts, it's easy to see that the SHARP-1421 is, by far, the most powerful and arguably better handheld for business applications, capable of running very long and complex financial programs dealing with large amounts of data at great speeds, while labeling all inputs and outputs and storing them on tape, sending them to a printer, or to a serial device.

Similar comparisons could be made between other HP models and their SHARP counterparts.

"¿What models do you consider the better one?"

It depends on whether you're considering them just for collecting purposes, only to use them, or both. Obviously, the very first models are much less powerful than the later ones, but they *were* the very best at their time, so the comparison would be unfair. Anyway, here's a commented selection of the ones I consider best:

  • Specialized for business applications: the SHARP PC-1421 (EL-5510) is an incredible machine, the very best bar none.

  • Specialized for statistics: the SHARP PC-1425 is to statistics what the 1421 is to business, another incredible machine with powerful statistic functions and data gathering and analysis features integrated with its BASIC language and up to 32 Kb RAM.

  • Specialized for number-crunching: the SHARP PC-1475, it has a large 2-line x 24-char alphanumeric display, very fast built-in matrix commands and statements including inverse, determinant and system solving plus a convenient matrix editor to enter and edit them, up to 128 Kb RAM for BASIC programs and data, a separate calculator mode & keyboard, a very comprehensive array of math functions, plus it features double precision for variables and results, up to 20 decimal digits.

  • General purpose: the SHARP PC-1262 is incredibly small (HP-15C size), metallic, has the same BASIC and I/O capabilities, 10 Kb RAM, 40 Kb ROM, 2-line x 24 char alphanumeric display, full QWERTY keyboard, comprehensive help menus, very fast.

  • General purpose, large screen: the SHARP PC-1350 and PC-1360 do have a large 4-line x 24-char, fully alphanumeric and graphic display, including specific graphic BASIC commands and statements. They admit up to 20 Kb and 64 Kb RAM, respectively, by using small RAM cards in various sizes, which keep the programs intact even when removed from the machine. This allows you to have a series of long, complex programs and data stored on cards and swap them in and out of the machine in mere seconds. And to top it all, you can interface them to RS-232 devices large and small.

    For me, it is the most pleasurable machine to write programs in without using paper, because of its large display, which can show many statements at a time, plus full QWERTY keyboard. You can do amazing graphics and menus with it easily.

There are many, many other models worth mentioning, such as the ultra-capable, 2-processor, 80 Kb RAM PC-1600, the incredibly built-in library and ultra-fast speed of the 544 Kb RAM (!), 4x40 display PC-E500, the specific models for machine language programming such as the PC-E220, the superbly beautiful earlier models (like the PC-1211 pocket computer and the EL-5100 and EL-5101 (left) advanced calculators, which surely are the most beautiful advanced calculators in the world), etc, but this post would get even more unreasonably long, so let's stop here :-)

Hello, Could you tell me what the Sharp EL1611P is ? The "P" in the name puzzles me...

I'm suprised that not too many people have quite a lot of machines. Of course, some people haven't spoken yet like GW (2029 calculators !!!!), JW, VT, DH himself, or the authors of THE GUIDE (about 1500 !!)...

I will just list the ones I do not HAVE:

LCD's 16C 9G 9S 49G+ 17BII+ 48GII 39G+

LED's 34C 31E 29C 19C 27 22 10 55 65 67 80 70

So I am missing a total of 19 of Hp's calculators. Boy am I in sad shape! I will have to buy a couple shortly.

But I will try to consol myself as to not having some of the above. I don't try to collect the business calcs, unless they just fall into my lap. 6 of the above are new Hp's that I haven't even seen retail.

So that leaves me with my must have list down to 16c, 34c, 27, 19c, 29c, 55, 65, 67. That is only 8 that I reeeally miss at the moment.

I also have a large collection of the DARD SIDE, Ti, but they are cheap and easy to come by (no $500 Ti-59, mine were much less). I have nearly every scientific USA released Ti (I didn't say all, as Ti has so many, and I have probably overlooked some model, and again, it would be easier to list what I don't have).

I have Casio's and Sharp's as well, but not deep collections as their difference in pocket calcs isn't as pronounced.

I an assortment of other brands as well.

I haven't yet done an actual inventory for two reasons.

I haven't taken the time.

But even more, I don't really care to let people know HOW ADDICTED I am to this hobby. ie Question, well how many Calcs do you have? Me, "Well, I have a lot." vs haveing to say some ridiculously high number and prove that I am past hope or help.

I bought an HP-41C when I was in grad school, over the counter -- not eBay!! -- within a couple of months of their being announced. How would I find out if it had "all the bugs"?

Being a young physicist, it is essential for me to use high quality calculators, now and during the next 20, 30 or even 40 years to come. As the situation concerning new RPN calculators (that work ...) is nothing but a pity, my "stock" is composed like this.

4 48GX ENTER x (1 used daily, 2 new in the box, 1 like new)

6 32sii ENTER x (1 used almost daily, 5 new in the box (4 of them brown ones), 1 like new)

1 42s ENTER x (for playing around sometimes, like new)

1 x 20s (because most of my high school students use it)

and not to forget the 200LX, great for running Derive and playing around with Pascal and for using those otherwise useless 8Mb compactflash cards that came with the digital camera.

None is like new or NIB, especially not the heavily used 15C. And I use them, especially the 48SX which has become my favourite and which I carry around all the time.

PS Is a soroban RPN? I'd say not, but it's not infix either, and certainly not prefix. But what, then?

A helpful person responding to my question posted on CALCLIST-L offered this about my machine's serial # ("LE-1307-271258"):

"Some information that you might find interesting. The LE-1307. The L stands for a whole series of Monroes in the L series. The E does stand for Educator. 13 is for 13 lower dials,and 07 is for number of keyboard rows."

And someone else came up with:

" ... Does your calculator have flip down legs at the rear? There were two different styles of cranks (old style), one for a thin case, and one for a full case. I believe the LE has a full case ... "

and

" ... This machine base is the Monroe L-160-X (old style), or LN-160-X (new style). The internal workings of both machines are nearly identical. The Educator series was a reduced features offering for school sales at reduced cost."

and,

" ... The calculator that you own was used in business colleges, and universities across the US for teaching purposes.

"The portable model of the calculator (L-160-X) was the machine that performed all of the calculations that built the American road system. Nearly every field surveyor employed by the US Bureau of Public Roads, and every state Dept. of Highways used one of these machines. I serviced these machines for several years, and usually dreaded the surveyors' off seasons when these men would bring dozens of the calculators in for servicing.

"The calculators were carried by salesmen and auditors. The portable versions of your calculator cost over $300.00. A lot of money at the time."

[Victor, based on its flip-up legs, I'd guess yours is a portable "new-style" model, maybe an L-series too. But don't take that to the bank -- I'm no expert.]

By the way, both of the folks who offered the information above are experienced Monroe service people, and one of them has spare parts available(!) (I was able to buy a handcrank and a xeroxed instruction manual for a very reasonable rate!)

So, bottom line: hook up with CALCLIST-L and you'll get more information than you may have thought possible.

I think I win for having the least calculators and the newest aged collection.

I currently have 3 calculators in my posession: A 32sii (silver bezel) A TI-89 and a 49g+.

The only one that actually belongs to me is the 49g+. (The 32sii and the 89 belong to my school).(And I didnt even buy the 49g+)

Favorite (of the 3): 32sii

Well, I guess you could count those old TI-30's that I haven't touched in over 2 years:)

I've never stopped to count them all. Somewhere in the mid-30s or so I guess (I'm not sure if the ubiquitous Ti-80 whatnots should be included). My favorite is probably the Sharp EL-5150, although right now I'm using an HP-11c at home and an HP- 97 at work for everyday calculating. But every now and then, it's fun to switch (the 35, 33c, 34c, 67, 71b, 28c, and 41c have recently had their turns).

Say, does anyone know anything about Kings Point calculators? I've got an SC-20 and SC-40 and they've been a hoot to poke around in (the SC-20 appears to be hand soldered!). I'd love to learn more.

I broke the ugly habit. While I've owned many over the years, I am down to one (HP-15C).

Buying the MoHPC on DVD helped me kick the habit.
