Editing Cherry G80-9009 (section)

==How to disassemble==
# Turn over, bottom side up. 
# Remove the 11 recessed screws in the bottom: 4 at the 'back' edge, 4 at the 'front' edge, one each on the left and right edge, and one dead-center. A couple may be under "Warranty voice if broken" stickers. All screws are the same size. 
# Note: There is no need to remove the four screws securing a plastic, rectangular plate.
# Turn the keyboard right-side-up, with its the back away from you. (Normal typing position) and pretending the back edge is hinged lift the front edge up. Watching the many wires between the top and bottom find a stable position for the top.
# Inside there are three PCBs: the main set of keys keyboard (0-9, A-Z, Num pad, etc.), the Function keys (F1-F24 and related), and finally the "main" PCB which contains more logic, ROMs, and the 3 DB ports that are exposed in the back.
# To separate the keyboard PCBs from the "main" PCB undo the gray ribbon cables at the "main" PCB end.
# There are grounding straps, but no screws holding in the main set of keys keyboard. If you undo the grounding straps it can be lifted out.
# Additional screws hold down the "main" PCB and Function keys PCB.
