MM5740 EMU

Hi,

II made an MM5740 emulator to replace the MM5740 IC. All the necessary information about it that may be needed for post-production is available on my website.

Very interesting,and did you

Very interesting,and did you use "normal CHerry MX" buttons as keys?Did you adjust the key holes for this on the PCB circuit board?The black plate for fixing and positioning the individual MX keys is well solved.Did you "print" the black plate yourself?

Greetings and thank you for sharingmikel

Thanks for the translation

Thanks for the translation help,But even with that I unfortunately can't find anything about the buttons themselves.If I have understood correctly, we are only using the previous Datanetics board and unfortunately it cannot be used directly for MX Cherry.So it's more about the equivalent circuit. I'm curious until someone with the skills to draw circuit boards brings a new MX variant.

There will be an article and

There will be an article and a video shortly about how the Cherry MX can be used on the original Datanetics PCB. Above will be the files for the spacer PCB and the plans for the support frame. Please be patient. I already have a video of it on my channel. There is no subtitle for the first part yet, but it will be too soon.

Pretty awesome to be able to

Pretty awesome to be able to replace an obsolete and hard to find chip like the MM5740 with something new and even better that it is programmable/customizable.
