The 8087 chip I added on to my 8086 system sits on my monitor pedestal, forever. Right now, it's next to my ()&(^&^%%$%^ Pixel 2 XL USB C audio connector. I was a grad student in numerical analysis and holy smokes! Hardware IEEE 754 floating point!
Sometime aroundish 1988 I paid $600 for an 80MB hard drive, out of a $12K/yr stipend. Good times.
