Hi, Csaba:

Yes, it is. Most SHARP PC-xxxx were also marketed in other countries renamed as SHARP EL-yyyy. I usually own one of each, though they're otherwise identical.

Quote:Do you have English pdf manual for SHARP PC-1421?

No, sorry, I only have the German pdf manual, which you can download using this link:

Financial Pocket Computer SHARP PC-1421 manual (German)

Nevertheless, apart from the financial functions keywords the rest of BASIC keywords and features are exactly like most other similar Level 2 BASIC SHARP pocket computers so any manual for those would do, the keywords and syntax are the same (though there were some other dedicated models with specific words for matrix operations, double precision (20 digits) and advanced statistic functions, and so the manuals for these specific models include dedicated keywords not present in the PC-1421/EL-5510).

As for the financial keywords, they mostly have the usual standard English names such as PV, FV, IRR, etc., and thus they're pretty easy to figure out if you're familiar with financial functions in general. The rest of the functionality can be easily deduced from the German manual by simply studying the many keyboard examples and the various financial application programs featured near the end of the manual. In a pinch, Google Translate can be used for very specific details.

There's also an Applications Book for this financial model, called (in English) "Dollars and Cents Computing" full of advanced financial programs using the built-in BASIC financial keywords, which can also serve as a useful source. I've seen it but I don't own it, perhaps it can be located as a net download or in TAS.

As a final comment on also using the financial SHARP PC-1421/EL-5510 for general purpose programming, not only does its 40 Kb ROM BASIC include all trigonometric functions in degrees, radians, and grads but also hyperbolic functions, linear regression, factorial, statistic functions, cube root, polar-rectangular conversions, the works ! Compare that to the HP-12C's function set ... Wink

The dedicated Statistics model (SHARP PC-1425) is even rarer than the Financial model, which is saying something (never located an English manual for it Sad ). I got one of those, too ! Smile

You're welcome !

It has no info on my favorite Sharp! The PC-G850VS. Sad
You can use the PC-G850V(S) user manual, translated into English by Jack W. Hsu.
There is also a thread related to this Cal somewhere on this forum.

Yes, thanks very much, I have Jack's great manual already (I followed when he released it here last year), however I had not discovered the page you shared before, so I've found many additional manuals here.

Also: Note that the PC-G850 manual on the linked page is v2.2, but Jack released version 3.0 a bit later.

Want to ask you all to give your opinion for the best (vintage) BASIC pocket Computers, taking into account the following aspects:

1. Amount of basic and upgradable memory.
2. Number of lines in display.
3. Flexible variable names (supporting two or more alpha characters).
4. Support for SUB routines
5. Support for separate user-defined function.

I am listening!

Thanks. I'll update the manual.

RE: What is the best BASIC Pocket Computer
I was into Pocket Computers long before I got into calculators. 'Best', as always, is subjective, but here are my favorites:

For sheer options and processing power, the Sharp g850 is the best. BASIC, C, Assembler, Monitor... this thing is a really great machine. Quite a few posts about it above, so I won't go into detail, but this is a very handy machine, even today. I have a BASIC dnd stats roller on mine for rpg sessions. Great machine, and sadly, the last of an era.

What's even better is that it's completely simple to build a serial <-> usb cable for these with about $5 in parts (arduino wires and an ebay usb signal converter) which makes transferring files a snap. My only gripe is the lack of RAM expandibility.

For portability, I really like the Sharp PC-1250/Tandy PC-3 line. Tiny, but not hamstrung like some of the other small form factor BASIC computers. I quite enjoy these, even nowadays. They are probably the best compromise of all of the smaller form factor models.

The Sharp e500 and Casio VX-4 also get honorable mention.
