Sure.
creating a 4.5 system, with the original order of
doloop doplusloop unloop in dict_core.inc
replacing words/doloop.asm with the file from amforth-4.4

building amforth with avra creates a working system --- I can
talk to it on the serial prompt.  :-)

I'm not sure, what to make of the current state of information.
So I leave this to the experts.
