[M3devel] using interpreter as a bootstrap

[Daniel Alejandro Benavides D.]

Hi all:
I guess that is the same as asking with a high-degree of compatibility a X mating machine core of a M3CG, and I believe it is the VAX-9000, it supported a CISC/RISC-core, but this was a huge machine, and so I think could be handy to get a sample of execution traces and match to  every other possible one.
I believe they made a RR on that machine:

Thanks in advance
