I'm not sure if this is in the right place, but here goes.
I have three chips from inside an Atari 2600, marked C010444D-19, C010750-12, and C010745-12.
I know the C010444D-19 is the TIA chip, and I'm wondering what the other two are, and what can I use them for.
My first thought when I found the TIA was "I should make an awesome synth with this!" but I realized this may not even be possible.
