A bit of dirt but not too much. Works on the AC cord. Has 2.02 bug. A little flakey-ness with the on/off switch and decimal point if not pressed right.
Nice! I see the back label is in great shape. It always nice to get extra literature. I have a flip book of program forms and a buyers' guide that came with my HP-65, so I can appreciate the extra stuff. That errata list is nice too, I wish they did that nowadays! I just hope that on/off switch doesn't get to you. If it does and you do take it apart, (you may already know this) you can gently clean the switch contacts, then bend the metal shorting bar that fits into the plastic switch out a little so that when the calculator is reassembled, the switch "clicks" nicely into place.
Make sure you read the manual, that's how I learned that 355 รท 113 approximates Pi extremely well.
Good luck,
Dan
