This week I have been cataloging some of my Rockwell Microcomputer Chips. These are very unique 64-Pin ceramic parts with lots of gold and very hard to find these days. I have noticed with Rockwell Gold IC's the gold leads tend to be more fragile than say Intel and others. I need to find the best way to preserve them as they get brittle, corroded and start to fall off.
Here are some I got today. They are all new old stock. Some are really nice and others have spots and marks caused by age.
