I have to agree, the PB1xx series are my favourite machine to work on, take the two case pieces apart and everything's right in front of you.

Speaking of replacing the LCD panels in these machines, I have to point out one thing - do not adjust the position of the display with the faceplate removed - the faceplate provides strength for the display casing, and with it removed, you run the risk of breaking the mounts for the hinges. I know this because over the years I've broken two of them myself, and now I unscrew and remove the entire, intact display assembly from the machine before playing with the panels.
