If you want Cherry MX keyswitches for future use, you might want to stock up. Cherry announced last year that production was moving to China, but today Mouser Electronics sent me an obsolescence notice for Cherry MX Blue.

EDIT: sorry if I caused any alarm. As several people have informed me, just replace the MX1A prefix with MX2A.

@brouhaha Is there any remaining justification to buy real Cherry MX switches instead of one of the many less expensive knockoffs? For that matter, was there ever a justification?

Personally, I prefer any of the Outemu silent tactiles.

@resuna @brouhaha I had not heard of that brand before. I'm planning to use some Gateron silent brown tactile switches in a Color Computer 3 keyboard upgrade.

If you make a keyboard PCB for the CC3, I'd like to buy one.

@brouhaha @resuna Cool! I’m still debating how to tackle connecting it to the computer. I don’t find any suitable pre-made flex cables available that would fit. How would you feel about desoldering the flex receptacle on the main board to replace it with a pin header?

Well, I'd prefer to be easily reversible, but it wouldn't be a disaster.
Do the cheap PCB companies in China not do cheap flex circuit? I haven't had occasion to look.

@brouhaha @NF6X you can get pre-made flexible flat cable and just have an adapter on your PCB.

The one for the Color Computer keyboard is very coarse pitch compared to the stuff made now. Maybe 100 mil pitch? I haven't looked at one in years. It seems unlikely that there's anything suitable off-the-shelf.

@brouhaha @NF6X

Molex advertises 2.54mm pitch FFC on their site.

I think you could trim this cable to work:

@resuna @brouhaha The same page shows that 0 are in stock, samples are not available, and the minimum order quantity (MOQ) is 1000 pieces.

@NF6X @brouhaha

Oh bother.

Show threadMark J. BlairApr 6
@resuna @brouhaha Yup! If this was a 0.5mm or 1mm pitch FFC then there would be tons of options available in single quantity. I don’t think 2.54mm pitch is commonly used enough any more for distributors to stock the pre made cables.

Cool! Thanks for finding that!
