And the 8051 is a particular bad one. It doesn't even have a
proper stack pointer.  I've written a couple simple kernels for
8-bitters like the HC11, and porting something as simple as
those to the 8051 wouldn't have been easy.  Porting something
like eCos to 8051 is, IMO, a practical impossibility.
