What a great project!
I hope stuff like this is still around when I retire, because right now it would just collect dust and make my heart heavy because I don't have the time to pursue such a hobby
If it's any peace of mind, the parts to build them should be available pretty much forever. It's possible I do more runs in the future :) Just for the sake of growing the Forth hardware community!

I find that's the most interesting aspect of this board. It's an excellent addition to permacomputing-optimized designs. It's a simple digital civilisation landmark for the ages. Or if you're pessimistic, the ultimate fallback computer.
