Oleg:

I do not want to break the party, but let me ask what is the goal of
targeting 6502 or Z80? These were wonderful machines some 25 years ago. Is
there any use for such processors anymore?

Let me point my finger at the lowest-end member of the Blackfin family,
that is BF592 with 68 kB on chip and the C run time library in ROM. It
costs $2 (when you buy a thousand chips).
http://www.analog.com/en/processors-dsp/blackfin/adsp-bf592/processors/product.html

Blackfin is a 32-bit chip. Its performance lets me ask whether there is
any payoff in spending effort addressing ancient hardware, if you can get
an inexpensive chip that is orders of magnitude more powerful?

If you do not like Blackfin then there is ARM.

If one wants to address some hardware that nobody is using, then maybe a
better target would be Wirth's soft RISC processor running inside the
FPGA? It is a fascinating project in my opinion.

Not that I want to criticize 8-bit chips. I am only wondering whether
anybody is going to use 8-bit chips in future.

Thank you,
Wojtek
