Hello all. This is my first time dealing with a computer this old. I am wondering if these gold caps are worth removing. They are marked with what I belive is a Texas instruments logo and a code of 8279251 LE 379274 and then a 80XX HG. I don't want to remove them, as HG is the periodic table symbol for mercury, and save myself the trouble if they are worthless. Thanks!

Are you asking about removing the IC from the board or just the cap from the IC? It looks like those ICs are soldered on the board so I would NOT try to remove them. That board would classify as Gold Cap & Gold Edge & CNC at $8.00/lb

I Mercury there. It’s just a product code.
You can remove the chips but without gold legs they will fall into one of the middle class ICs (Chris would have to let you know which one).
From there it’s a matter of weighing up the two different aspects and seeing which is more value, chips in or chips out.
Looks like old TI controllers
