sounds neat - do keep focussed, though.

btw is the div core in a position where it could be plugged in to the
FPDIV "stub" code?

 takes a lot to switch context/focus, doesn't it?  particularly on
complex topics.  i'm trying to keep the 6600-style memory work "in
mind" every couple of days, to keep it in "electrical neural memory",
so that when i come back to it after doing the FCVT etc. i don't feel
completely lost.
