The Z-80 has enough registers for Ada (or at least a reasonable subtest) --  
see the original Janus/Ada compilers. If you want *real* registers, even the 
x86 doesn't have enough registers for reasonable code optimizations. A 
"register architecture" is an iffy model for an intermediate language if you 
ask me.
