[Coco] Frank Hogg Labs E-Forth, which is the only thing I’ve found that won’t run on the CoCo3FPGA ?

Hi Dave, et al.
I'm finding it very interesting indeed.
I've tried E-Forth out on all the available emulators I have.
Only works correctly on David Keil's MS-DOS emulator, but it's difficult
to debug there.
Doesn't work on VCC or Jeff V's emulators, you just get a row of chars
for each keypress.
Still trying to work out exactly what it is doing....
