I wonder how hard/impossible it would be to implement this entirely in an
FPGA of some sort.   That would be a LOT of work, but extremely cool.

Start with the basic PDP-11/70 in that case. Once you have that down, extending it to an 11/74 should be less of a problem.

I know of several attempts in the past to do PDP-11s in FPGA. I don't know if any of them have reached a working stage, but they have also been aiming a bit lower. Going for 11/40 type machines.

But it should all be doable, I think. Just given enough time and energy. :-)
