Lets see, Stamp and Stamp II plus FEDBASIC. No doubt others which at
this point I cant recall. All of which do a good job considering the
access time for serial memory configurations. All utilise a caching
system for speed and optimum performance is achived by clever use of
subroutines and constructs. Yes I know these use interpreters but lets
face the fact, the interpreter reduces the development overhead and
although absolute speed is not what these little beasts are about, ease
of development is their biggest advantage...

A very specialised signals processor, not really tailored for general
purpose use...
