They can be dismantled... Getting them back together is the difficult bit :-) What I would do is take off the casing (2 hex-head bolts under the feet, unlatch the plastic clip in the bottom section and slide the keyboard assembly out), then separate the PCB from the keyboard membranes. From what I remmeber there's a clip that holds a regulator to the chassis, one screwm and you then bend up the tabs on the metal clips over the membrane tails and take the whole lot apart. With said clips removed, you cna conenct the PCB to the terminal with the normal modular cable. If it now gives no errors (very likely), you've got a matrix problem. You can remove the keycaps -- slightly twist them to free the locking hooks. There's even a special DEC tool for this -- I have it somewere, it came as part of a custom blank keycap kit. Now, the thing is heat-stakeed together. There are plastic housings with metal springs under them, then a rubber sheet, then the mebrane, them a metal base. Pegs on the plastic housings go through the whole lot and are moulded over on the back. It's triviel to take apart. The problem is leaving enough peg to be able to fix it all back again. I have wondered about making a hollow tubular cutter to remove the moulded-over bit from each peg, then putting said bits back on at the end and trying to melt the plastic together again. I am told this method has worked on HP handhelds with similar heat-staked assembiles -tony
