Unicomp Model-M a disaster --RESOLVED--

This weekend, flipping the membrane over, I discovered that I had totally removed some of the traces when I used the alcohol; so some of the traces were "cut" and will never again make contact with the controller board. So this keyboard is toast; Could you use some of the silver(?) conductive paint to re-draw the traces? Ohhh, I did not know about this. Found a "pen" of conductive paint, ironically from MG Chemicals (the 100% Alcohol is from them.) Darn, I have already removed a bunch of parts from the keyboard; guess I'll have to put it all back together now. Excellent suggestion, thanks! I will try this in maybe 2 weeks? Will come back and let you know if it works. Best Regards, http://www.pckeyboard.com/mm5/mercha...uc t_code=MEM Membrane assembly Price: $10.00 The problem is the membrane sits between the metal backplane and the black plastic base which holds the keys. The two (metal backplane and black plastic base) are held together by melting the black plastic rivet-like - I cannot separate them... Have a chat with them, see what they've got. They have seen this thread, I am pretty sure, and are probably not happy; they are not chatting with me anymore. But for a hundred bucks, I expected a working USB controller; there were different bugs on two of the controller versions I had. I expect bugs from some things, but not from a Model M keyboard. Regards, I have a membrane keyboard (now retired) and the membranes are welded to each other, but not to anything else. They fit over alignment pegs, and that's what keeps the membrane aligned with the key array. It made it very easy to clean. After a coffee spill, just pull the membrane pile and rinse in cold water for a while. The membranes can be held apart while it dries, then reassemble. How I ruined that, is removing the keycaps and cleaning underneath. That seemed to be too much for the thing. So on my keyboard (not the same brand as yours), the keyboard treated me really well. Now, if you take the $150 boat-anchor Apple keyboard, that one when I spilled coffee on it, the thing was riveted together, and an attempt to drill a rivet, just made it spin around. I rinsed that for a long time, dried it for a couple days in a gently heated airstream... and still three keys were sticky enough to not work properly. $150.00 out the window... Paul |

I'll have a look at it again, maybe I can pull it out without separating the keyboard and the backplane - there must be a trick, if UniComp sells the membrane separately. I would ask them what the tick is, but since they're not really talking to me anymore... They did send me a foam pad, free of charge, when I told them about my problem (or when they saw my post here,) so they still want to do the right thing; I'm pretty happy with the service I got from them.

See, using water on a keyboard is possible, lol, but make sure to dry those blucking springs properly, or they will rust! ;-) Best Regards, -- ! _\|/_ Sylvain / !
