Unfortunately that's a deal breaker for me Due to age related issues I can no longer solder things. I did for decades so I know how...

So my search for a decent emulator (not a simulator) continues. And yes Pierre I've tried yours.

You don't know anyone who would assemble it for you? I assemble kits for all my friends just for the pleasure of the assembly. In fact, when I buy a kit, I assemble it, test it then usually give it away or sell it cheaply because that's the fun of it for me.

Being attached to semantics, I will therefore repeat here the introductory message present on my site :

Quote:It seems that some people qualify my TI-58C program as a simulator on the pretext that an emulator is a program which takes the kernel (ROM) of a machine "to run" it, in computer science, in France, it is common to say "to process" it.
To be precise with French terms:
the verb "to simulate" designates the action of imitating, pretending. (The flight simulator represents well the action of imitating and feigning. Some women have the art of pretending or feigning : in short simulating.)
the verb "to emulate" refers to the action of trying to match or surpass... which my TI-58C program does!
When the execution of a ROM from a calculator, it would surely be more judicious to speak of "executor", or even of "processor" or ROM "engine".
In any case, I don't believe that my program imitates, pretends or feigns ..."

So, AnnoyedOne, if you are looking for a ROM microcode "executor" I recommend :

The “purist” TI59e of Hrast Programmer (https://www.hrastprogrammer.com/ti59e/ and http://www.hrastprogrammer.com/ti59e/ti59epc.zip)

Thanks for trying, and sorry it didn't meet your expectations.

That my definition of an emulator yes. Runs the original ROM code vs what anyone thinks it does/should do (simulator).

I've tried the Hrast Programmer emulator. No thanks.

PS: It seems that TI has threatened anyone who publicly publishes ROM images of ancient products. Their code and choice. I assume that's why there's are almost no emulators but many simulators.

Hi all.

Some insight, please. The faceplate of the ET-58 in the OP looks a bit crowded and cluttered with way too much nomenclature. Is that the actual faceplate or is that from a prototype?

That is the actual faceplate !

When, like me, you know the TI-58C keyboard, nothing monstrous.
Just a 3rd function to assimilate in addition.
3 functions per key is quite usual on HP... (without speaking about the WP34S)
To explain :
Above the button in large characters: the basic function
To the left of the button, upper text: the 2nd function
To the left of the button, lower text: the 3rd function
Ex:
the 1/X key gives tan if 2nd before 1/X and gives tanh if 3rd before 1/X...
(We can also make a color overlay)

[Pierre]

Among the "plus" I was going to forget :


the alphanumeric display that the TI-58C did not know!

To which must be added a list of 112 pre-recorded terms to help compose the texts.
(OK, ERROR, Diagnose, Result, Input, Enter, Index, Row, Column, Continue, STOP, Matrix, Complex, Number, Element, Item...)

Very interesting. TI deserves clones as well as HP. Will buy one when available.

@Pierre. tu as mis un drapeau hongrois au lieu d’un drapeau tchèque sur ton site.

@badaze. Merci mais je ne me suis pas trompé sur mon site mais sur mes deux sites !

I would certainly buy this clone if it was sold assembled...

Same here! (hint for ET-58 maker :)

Hé, les gars, pas besoin de chuchoter. On a du mal à vous entendre sans une loupe !

Hello Pierre, Thank you for pointing this out ! Nice ! And thanks to Miroslav Nemecek for creating the ET-58.
My first programmable device was a TI-57, I couldn't afford a TI-58 or 59. I had an oppertunitie to play with a TI-58 for a couple of weeks, and I still love it. So when I saw your post, I immediatly ordered a kit ! It arrived yesterday, but now I have to find the time to solder it.
Luckely there are only two smd parts, I'm no hero soldering smd

Regards,
Marc.

Hi Marc,
Congratulations on your purchase.
Don't hesitate to take pictures during your assembly work that will be useful to other fans. (and I can publish them on my site with your agreement!)
And your comments will be welcome.
For my part, being bad at electronics and especially at soldering, I can only help you with the use and programming of the ET-58.
For the manual you will have to be patient... I have as much skills in Czech as in soldering... but I will know how to do it!
I have already made a 259 steps program that I immediately transposed for the PX-41CX then for the HP-15C...
Have fun !
Best regards
Pierre

Hi Pierre,

I will take pictures when I assemble/solder the ET-58 and post them here, and you may put them on your site. The building instructions, in English, can be found at : https://www.breatharian.eu/hw/et58/index_en.html

I first have to make room in my office or storage. both are packed

Best regards,
Marc.

The Pajenicko.cz website has restocked the ET-58 kits and is therefore putting several of them back on sale!

[badaze]

I’ve just ordered one.
I just have to learn how to solder !
Cost 43€ shipping to France included.

Félicitations !
Je pense que vous aurez fini le montage avant que j'ai pu terminer le manuel.
Le manuel en français avance doucement...
J'en suis à une trentaine de pages sur 260 environ...
Plus que 230 pages à faire avant d'attaquer la version anglaise !

Congratulations !
I think you will have finished the soldering before I had finish the manual.
The French owner's manual is progressing slowly...
I am at about thirty pages out of about 260...
Only 230 pages to translate before starting the English version !

Hi Pierre,

I am ready soldering the ET-58, but I have to find out how to program the Atmega328p. I'm only familiar with pic microcontrollers, and Arduino ( also a 328p, but with a bootloader ).
For now I've used an ic socket so I can reprogram the 328p. It only makes the distance from the top cover plate to the pcb greater, I'll have to find out if this is workable once I have a working 328p.
I'll let you know if there's any progress.

Regards, Marc.

Hi Marc,

Thanks for the information.
I will be very interested in your progress.
