And speaking as someone who has has ported a real Forth to the 8051,
to be honest: that opinion is nonsense.

Eh?  Enough pointers?  All the architecture of the 8051 does is mean
that the Forth doesn't run very fast.  But an embedded computer olny
has to be fast enough.  IME, Forth code on the 8051 can be extremely
small, with byte token-threading.

Could be.  But that doesn't make it crap.
