If there is a new backend will it lend itself to writing code generators
for other architectures? Eight and sixteen bit microcontrollers would be
obvious challenges.
On the other hand; after having done some reading on the 8 bit
controllers, I'm not so sure that any programming language is
particularly suitable for these devices.
At any rate it looks like tasking would be no good. There is not much
context switching that can be done in 128 bytes or less.
However devices like the Z-80 (HD-180) and 68xx should be feasible.
