I think we do need *a* simulator other than the talos II server. When we 
have the core somewhat working, we will want to run a bunch of tests on 
it, and check those against a reference. While we can use the Talos as a 
reference, running code on it (I assume) will be a somewhat manual 
process, not really amenable to unit testing. If we have a simulator 
though, we can write (or randomly generate) a bunch of unit tests, and 
run them in the simulator and our core and compare the results. So we 
will need *a* simulator.

However, I do agree that we don't need 4.
