Now all the electronic and mechanical sections of your HP9800 calculator 
have been repaired, all that remains is to complete the reassembly.

In an HP9830, refit the {\bf Display} PCB fixing screw and check that the 
tape drive and expansion ROM unit are screwed in place. In an HP9810 or 
HP9820, check that the card reader and printer are screwed down. Refit 
the keyboard, hooking the bezel behind the printer paper guide if 
appropriate, and fit the 4 fixing screws on the underside of the machine, 
starting with the 2 nearest the back which screw into the metal pillars 
on the keyboard.

Do one final check of the machine's operation before refitting the PCB 
hold-down bars in an HP9830 and the top cover.
