An Intel and AMD CPU in the same motherboard at the same time?

This is the FIC 4386-VC-HD - a 386/486 hybrid motherboard released back in 1992. It has a multi-tiered PGA socket that can be used for a 486 CPU or a math co-processor. Because it has a soldered on AMD 386 DX/40 CPU, it is one of the few boards out there that allows you to have both an Intel and AMD CPU installed simultaneously. Obviously the 386 CPU will be disabled when a 486 CPU is installed, but it is still an interesting sight to behold! There was a lot more flexibility in this era of PC hardware than we see today.
