Having total control so it can be the way I want it can be important. I 
really don't know of any Forth whose main goal is easy porting which is 
the most important feature I desire. Most Forth are either all 
assembler, or a mix of assembler and Forth, either one is hard to port, 
there are a few written in C but they fail at being simple to understand 
and change.

eForth is the closest to those goals that doesn't break the bank and 
there are a multitude of architectures available, Indirect Threaded, 
Direct Threaded, Subroutine Threaded, and even Token Threaded versions 
of eForth so in the end that might not be a bad way to go but no matter 
what when a new FPGA CPU or an existing one is modified one needs to 
port the software to the new device.

Before I put a lot of effort into creating something from scratch it 
might be worth the effort to attempt to port an existing eForth version 
to a different CPU and see how practical that is. port ep16 eForth to 
become ep32 eForth that would be a nice test as I have working ep32 
software to compare it to. If it works OK then no need to write anything 
from scratch just port a new version as needed. ep16 CPU eForth to J1 
CPU eForth might also be a nice test since the CPUs are quite different.
