You are using fixed point hardware today.  Fixed point tracked the
"decimal point" (or "binary point" or whatever) in the mind of the
programmer, not in the state of the hardware.  There never was
"fixed point hardware," it was simply a way of viewing the results
of the gates of the same hardware we use today.
