I bet you'd detonate a LOT of code just by trying to compile it for one of
those ancient BBN C Machines.  Instruction set tuned for C, with only one
small catch:  10 bit characters.  Didn't last long, and that was an era when
people were USED to characters being "somewhere between 6 and 9 bits, possibly
different on the SAME machine".

I wonder how long it would take to get GNU C running on one?

I wonder if time_t would wrap before it could be accomplished...?
