41c vs 41cx display compatibility

[3p141592654]

Wow, thank you for that info. I went back and double checked. The seized 41cx is on 00041-80004 and the 41c is 00041-60004 as the photos show. I bought the cx when it first was released probably in 1985 so it would certainly be an early model. Its never been apart until now so its guaranteed to be as it was from the factory.

So I measured the motherboards and indeed, the 41cx is ~50 mil and the 41c is ~60 mil as you note. Excellent, that clears that up. Except I see no trace of 15 mil teflon washers. I must have overlooked them and now they are lost. Mcmaster has these which seem like they will work

Chemical-Resistant PTFE Plastic Washer, Number 8 Screw Size, 0.197" ID, 0.28" OD, 0.013"-0.017" Thickness

I'm not sure how to spot a tall key 41c but the measured key height is ~100mils for both.

So I did try flushing the rockers with IPA, but that did nothing. However, if its sugar then I need water not IPA. Do I literally dunk the keypad in a jar of DI water, or should I spray it on only the affected keys?
