OT: looking for pic of an ARISTO M27's backside

[Mike (Stgt)]

Wrong forum, I know. I once found in the internet a picture of the short instructions on the backside of the Aristo M27. And lost it in my filing. Today I tried to find it again, alas with no luck.
Anybody here who may point me to the right direction?

TIA.....Mike

Hello again,

here is the photo (a bit difficult to take, because the label is nothing but "raised white plastic on white plastic background")

Full size is here: http://www.bombie.de/tmp/IMG12553_5_6_tonemapped_fullsize.jpg

I have two of the three variants of the M27 and both have identical backs. Still missing the one without the "CE" key...

Ciao,max

Hallo Max!

Thank you very much for this excellent picture, it is realy perfect. Now my question: do you mind if I use it as "help" for a 4-banger I programmed with Delphi? My son has programming lessons at school and I assisted him a bit in the 'build a four function calculator' exercise. Looking for a fewest keys model I found the Aristo M27 ideal, in addition it has a good coloring and shaping. Like other calculator programs it has moving keys, error beep depending on the kind of error, keys with clicksound, changing cursor, and PC-keybord mapping. To simplify things it lacks calculating with constants and the display is made with fonts instead of pictures of the LED digits. But the backside picture as help screen would be nice because meanwhile I discovered that I accidentally used as faceplate the first calculator made in old Germany.

So I hope your answer will by yes.

Ciao.....Mike

Of course it is, since I took the photo for you (and your son) :-) I hope he enjoys the programming excercise as much as I did mine back then!

BTW: The Aristo M27 is one of the three calculators that I will keep if one day someone or something forces me to give my collection away (together with an Hp-25 and my faithful companion when I really needed a caculator: the Ti59).

Ciao,

Thank you very much for your permission! Of cause I will mention you as source of the original photo. I try to augment the contrast, may be I colorize it.

But - is the protokoll for substraction realy correct? To calculate 20-25 press C, 2, 0, +=, 2, 5, -. I assume there is a typo where += and - should be exchanged. As lucky owner of an ARISTO M27, could you please check this.

My son knows the emulators from Christoph Gießelink and as such he had the idea to use a nice faceplate/skin instead of a simple mask for this simple calculator exercise. Alas, because he lives not with me I could not show him my way unfamiliar with Delphi to get a result which was of much more importance - at least for me - than the result on its own.

I try to publish the result next month.

Ciao.....Mike

That's really not necessary!

It really works that way, I just checked to be 100% certain. But this kind of entry logic is not unique to that calculator. Quite a few other calculators of that era work the same way.

And regarding the "lucky ownwer": Yes for sure! What I really can't understand is that mass-produced memory modules for HP-41s from the late 80ies are sold for more than 100 Euros on eBay while you still can find absolute rarities like the Aristo M27 for less than 50 (I think I paid around 30 for each of mine).
