a) you cant roll back to membrane keybord....
b) it need somer work to do....and tools...
c) because shιιιιt hapent you take the responsibility... if you are damage your QL....(i checked and the keyboard works)
at second you need... the plate...
(i will give gerbers only in p.m of the rev 2 because now i install the rev 1 and i work on rev 2...)
tools(file.....rotary drill or dremmel sand papers solering iron...)
step 1.... remove everithing from upper case of the ql.... and the pilars that not have bolts .....
step 2 tri to match the plate circuit withe center of the keys.....y can use the dremel to center the bolt screws and the pass hole bolts....
step3 try to close the ql....(maybe you must move the plate little up-down-left or right to do this .....)
step 3(i done it with a 16 mm drillbit) remove the circular pilar of the old keys.....) picture 1
bold the pcb back or make the next step with the pcb out....
then you solder the cherry mx....(because we have not a plate that holds the cheery mx in line..... its allitle tricky to...solder it strait)
pic 3
the space stabilew with the space bar so do not damage it(all the system o stabilization)
part 7 take a cable of a disc drive or hdd and cut 9 and 11 wires...
solder the wires (the 11 is all from bottom of the pcb..and the 9 from the top so its difficut to mess the lines)
part 8
i found this... and is corrected of this board.,...4 keys is no rigth on the matrix o-9 and 1-3 its inverted)
