Re: Genuine Model M 1390131?

For sure many 1390131's have the "silver" instead of "rainbow plates". From what I've seen and from the 1390131's I've managed to acquire, it seems the early 1986 models are most likely to have the "rainbow" back plates. All of them are excellent boards but the "rainbow" plate ones do seem to have a...

Re: Numeridex Oak FTM Board Rebuild

This is way cool! So many rivets :o So I'd assume they server no real purpose? Thanks! I thought it was sort of an interesting board. The rivets are formed from the four corner posts of each switch and hold the switches and membrane to the back plate so they are important. I used silicone sealant t...

Are the stabilizers for the keys seated properly? If the keys are working with single unit keycaps, but not the larger stabilized keycaps, that could be the source of the problem.
