I just found my tools to re-open my broken HP50G (bought it for $5.00 on TAS). If you're hoping for some clues on how the traces are connected, you may be pretty disappointed. It's a multilayer PCB with very few traces visible from the front and back sides. The only exception is the LCD daughter board -- well, at least the portion not covered by the glass...
Anyway, I can take some photos tomorrow during daylight. My camera does a pretty poor job inside with the typical yellow lightbulbs
