By a special arrangement with author Eric Isaacson, we are including
evaluation versions of his A86 assembler and D86 debugger.  If you
decide to use these products to write your own programs, you should
purchase them from Mr. Isaacson, at the address given in the documentation
for those programs.  The complete package costs $90.00, and includes
some extra utilities not found in this evaluation version.

Before using A86 to assemble the source code listed in the book, it may be
necessary to make minor changes.  The macros, for example, in AO3.ASM need
to be modified.  A converted listing for this program can be found on the
disk, titled AO3_A86.ASM.  ASCIIORG.ASM will require no modifications.  Due
to the complexity of changes that are required for AO2.ASM, it has not been
converted.  It is suggested that you wait until you have a good understanding
of both assembly language and the A86 assembler before attempting this.

Mr. Isaacson has provided extensive documentation for the A86 assembler.  
Please refer to this documentation with any questions concerning the use
of this product.
