Well, there is good and bad news. The new v7 controllers are much
better than previous versions, even tho they still do that weird thing
when coming out of sleep mode. And the new foam pad Unicomp sent
worked great, all the keys that were ever going to work were now
working. Unfortunately, I had used 100% alcohol to clean the traces on
the transparent plastic "membrane" earlier, trying to get better
contact to the controller board. 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; my fault. I offered to send it back to Unicomp instead of
throwing it away but have not heard back.
I'll just buy another one if I need a gaming keyboard with no Windows
keys. I don't expect my current Unicomp WITH Windows keys to ever stop
working, these keyboard are like tanks. Sorry it took me so long to
update this thread. Conclusion is: If you have some issues with your
current Unicomp, especially during boot or sleep, get a new controller
board.

And that suggests that perhaps washing the keyboard in water
would have (slightly) damaged it too - if it was alcohol soluble.
Water might well have done a job on it too, as might spilling
a Coke on it (followed by frantic attempts to rinse it clean).
Well I only tried to clean the traces that were on the plastic
"membrane" which sits under the keys but which also protrudes from the
key area, and goes touching the controller board from below. I used 100%
alcohol from MG Chemicals, not rubbing alcohol. But the stuff is strong,
way too strong. Usually, when I clean contact points like this, I just
use a white eraser; I even have one with a deep groove in it to clean
the connector parts of expansion cards etc. On cheap "normal" keyboards,
or on remote controls, or calculators, I also use an eraser. But 3 weeks
ago, I went "Hey, I got this nice big bottle of pure alcohol" - Mistake!
I HAVE washed the keyboard part of Model M's with water in the past. So
long as you use something like a paint brush, to wash around the keyb
after having removed all the keys (which you can wash separately but let
them dry a full day before putting them back) then all is well. But
don't do like I once did, and just put the keyboard under the faucet
trying not to touch the holes where the keys go. You WILL screw-up and
/some/ water will make it into the keyboard. It's not as bad as it
sounds, but what happened, get this, is some of the buckling springs
rusted! So some keys were a bit weird after that (that particular Model
M was REALLY dirty.)
With this latest screw-up, I'm now pretty good on what NOT to do to a
Model M ;-)
