What type of equipment did that come out of. I've never seen one like that.

I think you might have sold it for several times the gold value before you removed the plastic 486 CPU.
It's a bit slow for the retro computing crowd but I think the CPU collecting crowd would have been interested in it. The asking price for a SX683 seems to be above $10 but it seems that a more realistic price would have been in the $8-$12 range.
Now it's just a piece of gold scrap with quite low gold content, I would just toss it in with black fiber pentium CPU:s and process it with the pins from those. The black chip probably contains some gold bond wires.
Are the pins magnetic (kovar based) or non-magnetic (brass)? How many do you have?

Now that I see it with the black chip on it I can recognize it. Thanks.
The second one is a power-pc CPU, probably from an apple computer. As far as I remember, those pins are easily removed by heat but the plastic will melt in the process, maybe the plastic can be peeled off first.
If the pins are based on copper alloy (non magnetic) then one alternative is to use a copper chloride etch to dissolve the base metal. It will take some time, produce quite a lot of waste for a small amount of gold but you will get an opportunity to refine some gold and learn something along the way.

If I remember correctly I peeled the black plastic part with the pins attached to it off with a thin putty knife, and sold it along with other green fiber cpu's.
