A word of warning to anyone interested in any of this stuff. I have parted out hundreds of machines in similar condition over the past 10 or 12 years taking every possible safety precaution I could and about three years I started having respiratory issues from doing it. PLEASE consider the risk to your health before you get involved with machines like this. The time & effort for the small financial return is bad enough but the health risks just are not worth it.
All of us feel like we are invincible when we are younger and typically don't think about long term health effects our actions might cause down the road. Messing with machines like the ones in these pictures just are not worth that risk. Spend a few extra dollars and start with something a little cleaner and you will likely live longer and have more time to enjoy the fruits of your labor.
If you are as "foolish" as I am sometimes - at least tear the stuff apart outside with plenty of air movement, try to work from the upwind side and be sure to wear gloves & a good mask as well as eye protection. "A little dirt has never killed anyone" but if you are exposed to enough of this stuff over time bad things will likely happen.
Thankfully I don't think I have anything really bad but I know my lungs will never be the same as they would have been had I not gotten involved with some of the really nasty stuff I tried to save. Thankfully about 6 or 7 years ago I "wised up" and started really avoiding buying the really nasty stuff. I still saved as much as I could but if something was really bad I just didn't even bring it home.
