Nice. Thanks for the update, Guy.

As I mentioned the other night, I'm peripherally interested in an
FPGA-implemented -10, but I have a definite budget - I'm willing to
roll a lot of my own hardware (loose parts, soldering, etc), but I
really can't justify more than a few hundred $$$ in total. I
certainly can't assist with the VHDL-end of things.
Once things get past the experimental stage and it's booting TOPS-20,
I'm likely to be more interested. My requirements are pretty loose -
if it runs one of the extant compiled versions of MDL Zork, I'm in.
