Man I'm old. I remember 5 and 1/4 inch floppies and 286 CPUs that you could upgrade to be faster for certain operations by buying a math co-processor. It was literally a DIP style IC chip youd insert on your mother board.

I remember upgrading my computer back then with one. It was a store in the city that had this glass case with various IC chips in plastic cases, no box or pretty packaging but it had a sort of sterile beauty to it with a little holographic sticker on it I think.

Its weird I was pretty young at the time, barely into my double digits. Only went to that particular store once. But I can recall exactly what the inside of the store looked like and even the city block it was on.

It invokes strong feelings of nostalgia.
