I believe Dave has previously approached Casio but got no reply.

Yep, no reply  :(

Right. Not easy task to get in touch with big Japanese company about your small business offer. Regional office shall be tried first to get at least some contact, then you work your way up the food chain:

I found the head of product marketing on LinkedIn and emailed direct. It's possible that it wasn't the right email, but it didn't bounce.

With 32K followers on Twitter, maybe worth a tweet asking if anyone has any contacts at Casio, or can translate a request into Japanese ?

Casio makes great calculators don't get me wrong, but the build quality I think has nothing on the vintage Casio FX-82 style calculator. Something like that with modern plastic buttons and inserts and a dome keypad on pcb would last forever. The aluminum keypad bezel and the LCDs they were using back then have stood the test of time as well. The Casio FX-61F is a little too flexible for my liking.

Then again if you were doing things from scratch going the landscape HP 15C route (w/optional RPN) wouldn't be a bad idea either.

I wonder what would it take to manufacture made by Casio EEVblog calculator (maybe as crowdfunding project)? I would love to have such next to my fx-991es.

I would definitely see an EEVBlog branded calculator with functions and capabilities like this FX-61F (electronics engineering), but with directions and input from Dave to the manufacturer. Just like with the 121GW.
Oh ... it wasn't supposed to do that ... is it ?

Maybe the Swiss Micros guy would take up the challenge?  I've got his DM16C "programmers calculator" and it's glorious but highly refined for bit twiddling.

I have 2 of these calculators, one working and one with the LCD broken. I've emailed casio several times about a replacement screen over the years. The first time was late 90s early 2000s. And they quoted £25 to repair the calculator, I waited several months and then got in touch again ready to send the calculator to be repaired and pay the fee. Unfortunately, the several months from my fist inquiry until I acted on it was long enough for casio to no longer repair them. I've also asked them several times if any models of a similar age use the same LCD, but they don't have details on such things and no interest in looking I guess.
Does anyone know if there are compatible screens on similar casio calculators? I'd love to revive my old one

I have a Radio Shack EC-4014 which is made by Casio and looks to be the baby brother of the pictured unit.

I had a quick look for you and found the same series all seem to have unique displays.

If you want to research this yourself inside the first few pages of the each calculators manual they show the display layout of the calculator. The product catalogs also show most of them are different.

I never though of looking in the manual, I still have a pristine manual and box for the 61F
Thanks for your input. I feared the screens would all be different.

If you have a spare manual for loan or for sale I'm interested. Ideally I want to end up with a good electronic version of the manual that is easy to read.

His LinkedIn profile states that he has quit Casio in 2016, so two years before your post. Perhaps it's time to find someone else now.

Hmm, perhaps!
If anyone has any linked I'd be glad to contact them again.

Are you asking them to build a reproduction of the FX-61F or other 80s-era calculator?  I'd be all over that, but I can't imagine it's even remotely possible.  Never mind the parts, the tooling will have long since been obsoleted or lost altogether. 

They'd have to charge thousands of dollars per unit to justify a limited run, I imagine.

I'd settle for a modified FX-260
The housing for the CFX-400 watch still exists as a databank calculator, it would just need a new LCD, chip and key overlay.

Hi, so i recently bought an fx-61F that came with a manual. I tried to scan it at a reasonable quality.

What a champion, thanks you did great job on that. Even though the contrast is lower it's very low artifacts from bleed through so way easier to read.

The manual from Daywalkerdha is lower contrast so way less artifact noise from bleed through. Appreciate both your work on this.
FYI, the way to prevent bleed through when scanning is to put a black backing sheet on the reverse of the page being scanned.

Looks even better now, higher quality seems to make the page alignment a bit more noticeable. In the past I found rescanning pages as I went produced better results than using processing for alignment. If I recall correctly I changed my desktop to a lower resolution and used the scan preview and crop tool as a ruler to check text/table/line alignment which made it fairly "quick" (which it never is).

Tooki sounds like he wants to volunteer to proof read the manual changes. :D

It appears that the post from Daywalkerdha has disappeared - can anyone provide the scanned copy of the manual?

Can someone please upload that scan somewhere? Makes no sense to PM and mail it to everyone.
