MY to MX

Hello good people of Deskthority!

I have recently been lucky enough to procure a Cherry G81- 8308 for only 10€.

Now what I have been wondering is, could I in theory rip out those membranes, put a Cherry MX PCB in and install some proper switches? Has that been done before? The metal plates in an MY Board do make them heavier and seem more well built..

So, in theory you'd only keep the case, right? Sure, why not?

Ahh, but I want to keep the macro functionality of those 24 PF keys. I guess I would need to keep the controller for that to be possible, right?

The G80-3000's matrix is probably not identical to the main matrix of the membrane in the G81-8308. Or maybe it has two membranes.

What does it look like inside? Please post pictures (and post an article in the Wiki about it)

Here are two pics I took long ago:

Just taken 2 pics, first one with top part of case lifted, second one with complete plate assembly also lifted:


Hope it helps.
And for your information, GMK offer what can be called a G80-8308, which in fact seems to be a MX-modified G81-8308: ... yboard.pdf

Ahh, but from GMK it would probably cost a pretty penny, whereas I got the G81-8308 for cheap.

Hmm..looking at these pictures, putting in a pcb with proper switches could be a thing. Will have to compare dimensions between a G80-3000 and this thing. If it fits, that would be nice.

Well, good news and bad news.

Putting in a PCB and trying out if it worked was easy. However, while I was desoldering the Blacks on the PCB to put in the switches I desired, all kinds of stuff on the PCB just came lose, including the green stuff on the lanes. Chyros is right about one thing in his videos: Those PCBs really are shit.
