Where is the joke?
Depends if you have been watching Intel attempts at SBC's/SoC's.
I'm not sure if they are serious or just messing about having fun.
I've used PC104 and Advantech boards too.
Had thought of making a PC104 adapter/motherboard board for the Pi's.
But my list is Pi projects is very long now.
Compile a PC bios on Pi's?
Coreboot, OpenBIOS, OpenBOOT.
Got a collection of PC motherboards from 486 upwards.
But so old, no parts and schematics.
Cam we design/make a Retro PC and code it with Pi's?
I'm dancing on Rainbows.
