I recently succeeded in getting my Lucas board to work in my A1000,
and I have been comparing some benchmark tests to the results I got
with a 68000 installed.  While the machine now runs faster, I do not
get nearly the speed increase quoted in the Transactor article.
In addition, the benchmark programs on the Lucas disk do not run
as fast as advertised (they are about a factor of 10-20 slower than
given in the article, and about a factor of 2 faster than with the
68000).

I have an A1000 with 1/2 MB and one external floppy.  The Lucas board
is running at 20 MHz (with 16 MHz parts).  I am using Workbench 1.3,
and I believe that all the standard libraries are in the libs directory.
I am compiling with Manx 3.6a, and have tried using the +2 and +f8
compiler switches, with either ma.lib or mt.lib (in all cases I have
used 16 bit ints, small code and small data models).  When I use
the +2 and +f8 switches, everyting seems to compile and link fine,
but the machine crashes.

Any suggestions would be greatly appreciated.
