The PDP-10 could fall into this classification without too much arguing.
It had its set of 16 general purpose registers defined simply as the
first 16 locations in memory.  Naturally, they implemented the the
"registers" as logic (register files) rather than core (in the first
ones).  The secret way to get your program to run really fast in
a tight loop was to load it into the registers (up to 16 instructions)
and then jump to one of the registers......

Ok, so its not so fast nowadays....   .....but still kinda neat
