Decided to start with the terminals first. I cleaned up and tested the DG Dasher D200, and it come out fairly good and all tests indicate it's working fine. No pictures of that.
The Dasher TP1 is much more of a hard-luck case, and I just finished cleaning the top of the top chassis. I did not clean the bottom chassis or stand or insides yet, so you can see a good comparison of the cleaned top half and the untouched bottom half. 7 pictures (unfortunately newest to oldest) are at https://www.flickr.com/photos/131070638@N02 No, there's no retrobrite involved. Just a normal spray on household cleaner, followed by Magic Eraser and a lot of elbow grease. Yep, Magic Eraser is a wonderful thing. J
