Once you have chosen your Hardware Design Language (VHDL, Verilog or one
you have implemented from scratch in CL) you can start writing the
"Symbolics type CPU".
Can you estimate the cost for this enterprise?

This assumes you have the OS. Can you estimate the cost of this enterprise?

Again, can you estimate the cost of this enterprise, given the cost of

Yes. And this is usually beyond the time-frame of a Ph.D. thesis.

Once you have done all of the above, yes.

It isn't hard. It's costly.

How about helping on many other less risky, less costly, more directly
useful projects out there first? McCLIM for example.
