Look what I just got! (slightly OT)



#16

I found an interesting non-hp recently. It's a Radio Shack EC-4018. I have never seen one like it before, works great and nice big number keys. This folds up like a Casio fx-411 and is about the same size. I've never seen another one with two solar strips at that either.

Here's a pic. I am not selling this baby...

There was a time when Radio Shack sold SHARP machines under the Radio Shack brand. Does this seem to be a SHARP in its design? Have you looked for it at RSkey.org?


#18

I have not seen it anywhere online.

Casio has a unique display for sexagesimal numbers and fractions, AFAIK (degree symbol and hooks, respectively). Does these symbols show up?

E.g., if you enter 1.5 and inv-[°'"], will the result show up as 1°30°00?

It looks really caso-ish.

Great. Further indications are having the display modes invoked by "mode 7" to "mode 9" and Ran# to get a random number.

Yep, that's likely a Casio :-).


#22

I wonder what Casio model number it is...


#23

It is function wise similar, but not identical to the fx-100c. Well, in the early 80th Casio made a lot of different models around similar displays and software. E.g., the only difference, beside the case, between the fx-180p and the fx-3600p ist a HYP key. The fx-190 is also clearly based on these models. I wouldn't be surprised if Casio put something together exclusively for Radio Shack and that it didn't take longer than a few days to develop it ;-).

The konstant registers seem to be missing, at least, I can't identify kin/kout keys. Thats very unsusual for a Casio at that time.


#24

Casio are also famous for having multiple product numbers for exactly the same product, depending upon the market it's sold into. Makes researching models a real pain.



This calc is almost identical in functionality to my Tandy (Radio Shack) EC-4014. Right down to the shifted functions on the keys. Except mine has a an ENG key to replace the ON button. The
FX-85M is very similar as well.

Not at all. The older Casio calculators use M+, M-, M in, and MR for number storage, which are present in the calculator shown, whereas kin/kout keys appear on later models.

Best regards,

It must be programmable to qualify for Viktors site. His site name is "R/S-key" which should be obvious.

okay, I said I won't sell it, but I would be willing to trade it for 10 HP-42S mint condition calculators. Nothing less.

:)

To Dave: Obviously I am not trying to post a real classified for this or anything. I just am showing off a little.

I'd bet that it's made by Casio. It shares many design traits and elements of functionality with my 1981 Casio fx-3600P.

Very nice.

What size is it?

Does it have dual solar/battery operation?



Interesting, I apparently found a "service manual" for it!:

Yes, thanks, but I saw that link too, but it does not seem to be anything.

When it is folded up, like a Casio fx-411/fx-451, it is 4.5" x 3". The display size is 2 5/8 " wide by 5/8 " tall.

I think it is solar only. I do not see any way to change batteries on this.
