Yesterday I de-globbed the 18 Tiger games that go with the last 2 batches of SVGs. 2 came out perfectly clean and I could read the die ID on 8 more. Today I cleaned the epoxy off the 16 dirty ones with hot sulfuric acid. I put the 8 that I could read the IDs into one beaker, since I can sort them out by the IDs, but I had to do the other 8 one-by-one. I also cleaned the Tetris and Golden Tee CPUs, and Whinked the 2 Tiger dies that were clean.
Sulfuric acid works much better on the epoxy than nitric acid, but it didn't clean stuck plastic off a TI die at all.
