Phil & everyone else with an Obtronix-

I have been unable to figure out what the failure is.  I talked with
Rich Dreher about it, but he unfortunately sold his Obtronix
(presumably to fund the CFFA 3000).  I've added the old trace code
back into John Matthews' code and I watch the Obtronix run off into
the woods while traversing the linked list of vocabulary entries.
Works like a champ on the Replica1.  I can only speculate the DRAM
refresh is confusing the SRAM on the CFFA1 and causing spurious values
once in awhile.  I also have lock-ups with other large programs on my
Obtronix that I downloaded from Vince Briel's site - including the
figForth without CFFA1 support.  I even tried swapping a 65C02 into my
Obtronix and an old 6502 into my Replica1 without any change in
success/failure.  I really don't have any more ideas.

However, if you have a Replica1, I've updated the release to 1.2.  It
only makes some small improvements to the memory footprint and file I/
O.
